Green Job Series: Careers in Sustainable Forestry [Second Installment]

Fires have an important role in forest ecology. In some extreme forest conditions, small fires turn into large, catastrophic fires that cause significant damage to the forest. However, some species of trees release seeds and spur new growth only in the presence of fires. Managing forest fires is an important part of sustainable forestry.

This installment of The Daily Leap's green job series profiles selected fire protection and prevention occupations in sustainable forestry.

Fire Protection and Prevention Occupations

Workers in these occupations typically spend most of their time outdoors, sometimes under potentially dangerous conditions. They use a variety of tools and equipment in their work. Fire protection and prevention workers must be physically fit, because their jobs are physically demanding and may involve walking long distances through heavily forested areas and wetlands.

Job Duties

Forest firefighters use heavy equipment, hand tools, and water hoses to control forest fires. They also create fire breaks (gaps in vegetation that slow or stop the progress of a fire) to deprive fires of fuel. Some elite forest firefighters, known as smoke jumpers, parachute from planes to reach areas that would otherwise be inaccessible.

Forest firefighters are expected to respond to forest fires during all hours of the day and night and may spend several consecutive days or weeks fighting a fire. Many forest firefighters work on a seasonal basis, generally from early spring to late summer.

Forest firefighters sometimes assist foresters with conducting controlled burns, in which fires are intentionally set to clear underbrush and manage the growth of plants and trees in the forest.

Forest fire inspectors and prevention specialists inspect forests for fire hazards. They look for problems that pose a wildfire risk and recommend ways to reduce fire hazards. They patrol forest areas, to ensure compliance with fire regulations, and report fire conditions to a central command center. Most forest fire inspectors and prevention specialists work for state and local governments.

Education and Training

Forest firefighters need to be at least 18 years old and need a high school diploma or equivalent. They are required to pass a physical fitness test, and they receive most of their training on the job. Firefighters who plan and oversee controlled burns must complete additional training and become certified as a burn boss.

Forest fire inspectors and prevention specialists have at least a high school diploma; however, some positions require that workers have an associate's or bachelor's degree. Work experience in firefighting or fire suppression also may be necessary.

Earnings

The table that follows shows wages for selected forest fire protection and prevention occupations in May 2012. The wages shown are median annual wages for the United States as a whole; wages vary by employer and location.

Tomorrow's sustainable forestry series installment: Science Occupations.

Green Job Series: Careers in Sustainable Forestry [First Installment]

Trees provide many of the products, including lumber, paper, and cloth, that we need in a modern economy. Sustainable forestry ensures that forests are used in the most effective way and trees are protected against the harmful effects of pollution, fires, pests, and diseases, and they are not overharvested in a manner that does not allow regrowth and regeneration.

Jobs that are involved in this balance of fulfilling consumer needs and preserving the forest environment relate to careers in sustainable forestry. This installment of The Daily Leap's green job series profiles selected forest conservation and logging occupations in sustainable forestry.

Forest Conservation and Logging Occupations

Forest and conservation workers and loggers who practice sustainable forestry cultivate and harvest thousands of acres of timber each year in environmentally friendly ways. Conservation and logging work is physically demanding, and logging jobs can be hazardous. Workers spend nearly all of their time outdoors, sometimes in poor weather and often in isolated areas. Loggers work in teams, with each worker specializing in a certain task.

Job Duties

Forest and conservation workers help to develop, maintain, and protect forests. Under the supervision of foresters and forest and conservation technicians, forest and conservation workers help to sustain and develop forests by doing tasks, such as planting seedlings or removing diseased trees. They may spray trees and seedlings with insecticides and fungicides, to control insects and weed growth.

Forest and conservation workers may work on tree farms, where they plant, cultivate, and harvest different types of trees. Workers who are employed by state and local governments clear brush and debris from trails, roadsides, and camping areas. Forest and conservation workers who have a fire protection background may help prevent fires by constructing fire breaks or assisting with controlled burns.

Fallers cut down trees with hand-held power chain saws and mobile felling machines. They ensure that the tree is cut safely, so that it falls in the direction desired to avoid hitting other workers or landing on equipment.

Logging equipment operators use tree harvesters to fell trees, shear tree limbs, and cut the trees into desired lengths. They drive tractors and operate self-propelled machines, called skidders or forwarders, which drag or transport logs to a loading area.

Log graders and scalers inspect logs for defects and measure the logs to determine their volume. They estimate the value of the logs or pulpwood (logs that are ground up for paper products). These workers often use handheld data collection devices to enter data about trees.

Other logging workers include buckers, who trim the tops and branches of felled trees and buck (cut) the logs into specific lengths; choke setters, who fasten chokers (steel cables or chains) around logs to be dragged by tractors or forwarded by a cable-yarding system; and rigging slingers and chasers, who set up and dismantle cables and guy wires of the yarding system. In addition, log sorters, markers, movers, and chippers sort, mark, and move logs based on species, size, and ownership, and they tend machines that chip up logs.

Education and Training

Forest and conservation workers typically need a high school diploma before they begin working. They generally get on-the-job training by helping more experienced workers. Most logging workers have a high school diploma. They get on-the-job training, to become familiar with forest environments and to learn how to operate logging machinery.

Many states have training programs for logging workers, which may include technical instruction or field training in areas such as best management practices, environmental compliance, and reforestation. Safety is a vital part of a logging worker’s instruction. Tree fallers require more skill and experience than do workers in other logging occupations, so fallers typically work under the direct supervision of more-experienced logging workers.

Green Job Series: Careers in Water Conservation [Fourth Installment]

This installment of The Daily Leap's green job series profiles key construction occupations in water conservation.

Construction Occupations

Construction workers build and install the infrastructure for conserving water. They build new water delivery and storage systems. They also build new dams and reservoirs, dig wells, lay new pipes, and install water-efficient appliances and irrigation systems.

Construction workers typically are employed by construction or utilities companies and spend much of their time outdoors. Their work can be physically demanding.

Job Duties

Construction managers oversee building projects. These may include constructing reservoirs and water treatment plants or installing new pipes and water delivery systems. The primary duties of a construction manager include administering permits, contracts, and the budget, as well as monitoring project quality and safety.

On large assignments, a project manager typically oversees several construction managers who supervise individual aspects of the assignment.

Construction laborers do many of the basic physical tasks onsite. They may clean and prepare construction sites, load or unload building materials, dig trenches, backfill holes, or compact earth to prepare for construction. They do a variety of tasks, from easy to difficult and even hazardous, on almost all construction sites.

Equipment operators use heavy machinery to move construction materials, earth, and other heavy materials at a construction site. They may dig trenches for pipes or clear a large area for a planned reservoir. Equipment operators also control cranes to lift and place heavy objects, such as collectors and storage tanks for rainwater or greywater. They set up, inspect, and adjust equipment and do some maintenance and minor repair.

Pipelayers place pipes outdoors. They install large-diameter pipes, such as water mains, or smaller pipes that carry water from the main to houses or buildings. Pipelayers may also install sewage systems that carry waste to treatment plants.

Plumbers follow detailed construction drawings to install pipes and appliances in buildings and connect them to the water supply. They may remove older fixtures and replace them with water-efficient ones, such as dual-flush toilets and low-flow faucets. Plumbers may also replace leaky pipes or install plumbing systems that accommodate both drinkable and non-drinkable water and thereby allow a building to use rainwater and greywater.

Septic tank servicers and sewer pipe cleaners ensure that septic tanks—tanks that store human waste when sewers are not available—and sewer pipes are clean and that waste material is able to flow through them properly. If septic tanks or sewers become blocked, the waste material backs up and may flow up through drains or seep into the ground nearby, which can contaminate the water supply.

Education, Training, and Licensing

Construction managers typically need a degree in construction management, business management, or engineering and have experience working in construction. Experience is important for construction managers, so it may substitute for some educational requirements. Workers who have an associate’s or bachelor’s degree in construction management or engineering but do not have significant construction experience may be hired as assistants to construction managers. Construction laborers are not required to have a formal education.

Equipment operators often learn on the job, complete an apprenticeship, or do a combination of both to become certified. Becoming certified involves training and testing to ensure competence and safety. Because of safety concerns and the potential danger of operating this equipment, most construction workers are required to pass regular drug screenings.

Pipelayers typically need a high school diploma and are trained on the job in 1 month or less. Plumbers also typically have a high school diploma and receive training through an apprenticeship, which usually lasts 4 to 5 years and involves about 1,700 to 2,000 hours of paid on-the-job training and at least 246 hours of related technical instruction.

Septic tank servicers and sewer pipe cleaners need less than a high school diploma. They are normally trained on the job and are competent in performing their jobs with 1 to 12 months of training.

This installment of The Daily Leap's green job series describes construction and material-moving occupations in environmental remediation.

Construction and Material-moving Occupations

Construction and material-moving workers operate the machinery that is used onsite in a remediation project. These workers might be exposed to contaminants and might be required to wear safety gear such as chemical protective suits and breathing apparatus.

Job Duties

Construction laborers do many of the basic tasks on remediation sites. These workers do physically demanding work, such as removing debris and possible hazards, loading and unloading materials, digging trenches, and operating machinery. They are used when there is no danger of exposure to dangerous chemicals or when the site has been made safe for them to work.

Dredge operators excavate waterways. They remove sand, gravel, or rock from bodies of water that have become contaminated. They might operate from land-based dredges or those mounted on barges or ships to remove material that is then either disposed of or treated to remove hazardous materials.

Earth drillers operate machinery that is used to drill into the earth. Because many remediation techniques involve drilling deep into the ground to remove pollution in the groundwater or below the top layers of soil, drills are used to reach the deep layers of rock and sediment underground. Drillers are needed for pump-and-treat techniques and are used occasionally for other techniques when the pollution has seeped deep underground.

Excavating and loading machine and dragline operators use machines equipped with scoops or shovels. They dig sand, earth, or other materials and load them onto conveyors or trucks for treatment or transport to disposal sites.

Hazardous materials removal workers identify and dispose of materials that are flammable, corrosive, reactive, or toxic. They are responsible for cleaning up sites that are severely contaminated and must be made safe for other workers to enter. They might deal with sites that have chemical, biological, or even radioactive waste and must wear special suits and respirators to keep them safe from these materials. They must be familiar with the procedures for handling and disposing of certain types of hazardous waste.

Operating engineers and other construction equipment operators drive, maneuver, or control the heavy machinery used in remediation projects. They work with one or several types of power construction equipment and might operate excavation and loading machines equipped with scoops, shovels, or buckets that dig sand, earth, gravel, or similar materials.

Education and Training

These construction and material-moving workers require on-the-job training to become competent in their occupations. Construction laborers and dredge operators generally undergo on-the-job training that lasts one month or less and do not need formal education. Excavating and loading machine operators also do not need formal education, but typically have prior work experience as construction laborers or construction equipment operators. They typically undergo moderate-term on-the-job training that can last between one month and one year. Equipment operators and earth drillers typically have a high school diploma or equivalent and also require moderate-term on-the-job training.

Hazardous materials removal workers typically enter the occupation with a high school diploma or the equivalent and are required by the federal government to complete formal training programs, such as an OSHA-certified HAZWOPER training course that lasts approximately 40 hours. They also need to be trained in the proper handling and disposal of hazardous materials and in any safety equipment they might be required to use, such as respirators or self-contained breathing apparatus.

Earnings

The U.S. Bureau of Labor Statistics (BLS) currently does not have wage data specific to the environmental remediation industry. The table that follows shows wages for selected construction and material-moving occupations in the waste management and remediation services industry group for May 2011.

Green Job Series: Careers in Environmental Remediation [Second Installment]

Several types of workers are involved in environmental remediation. This installment of The Daily Leap's green job series describes engineering and mapping occupations in environmental remediation.

Engineering and Mapping Occupations

Engineers who work in environmental remediation devise technical solutions for cleaning up pollution. They work closely with scientists and other remediation workers to implement the best methods for remediating polluted areas. They also might be responsible for developing methods to increase safety and to reduce the risk of illness and injury for a company's employees.

Engineers are employed by a variety of organizations, including businesses, government agencies, and consulting firms. Most work in offices or laboratories, but they might travel frequently to remediation sites.

Job Duties

Cartographers and photogrammetrists measure, analyze, and interpret geographic information to create maps and charts. The maps and charts detail areas of contamination, as well as the physical characteristics of the site where remediation will be carried out.

Chemical engineers apply the principles of chemistry, biology, and physics to develop remediation techniques. Much contamination is chemical in nature, and many remediation technologies use chemical processes to deal with contaminants.

Environmental engineers use the principles of engineering, soil science, biology, and chemistry to solve environmental problems. They work to control pollution, clean up polluted areas, and monitor the progress of remediation projects.

Environmental engineering technicians carry out the plans that engineers develop. They test, operate, and, if necessary, modify equipment that is used for the cleanup of environmental pollution. They might collect samples for testing, or work to mitigate sources of environmental pollution. They might also assist in the inspection of the site for compliance with regulations.

Health and safety engineers combine knowledge of health or safety with systems engineering techniques to make sure that chemicals and other products are not harmful. In remediation projects, they ensure that workers are safe from contaminants.

Mining and geological engineers use geology to evaluate potential remediation sites. They study the geology of the local area and work with geoscientists and other scientists and engineers to determine the most effective techniques for remediating a particular area.

Education and Training

Cartographers and photogrammetrists require a bachelor's degree in geography, engineering, or physical science. Some states require cartographers and photogrammetrists to be licensed as surveyors, and some states have specific licenses for photogrammetrists.

Engineers must have at least a bachelor's degree in their specific engineering field. Many engineers are certified as a professional engineer (PE), a certification that requires several years of work experience as well as passing written exams. Employers also value practical experience, so many engineers start out assisting more senior engineers, and with experience, they take on more responsibility and more complex projects.

Environmental engineering technicians typically have an associate's degree from a technical or community college.

Earnings

The U.S. Bureau of Labor Statistics (BLS) currently does not have wage data specific to the environmental remediation industry.

Next week's environmental remediation industry series installment: Construction and Material-moving Occupations.

Green Job Series: Careers in Environmental Remediation [First Installment]

Environmental remediation is the removal of pollution or contaminants from water (both ground water and surface water) and soil. These waste products are removed for the protection of human health, as well as to restore the environment. In some cases, a site is so contaminated that it can only be fenced off and isolated as much as possible from the rest of the environment.

Several types of workers are involved in environmental remediation. They might be employed by companies in architectural, engineering, and related services industries; by management, scientific, and technical consulting firms; or by state, local, or federal government agencies.

This installment of The Daily Leap's green job series describes science occupations in environmental remediation.

Science Occupations

Science workers perform studies of the areas that will be remediated and help to determine the best ways to conduct the remediation. They perform tests to see which pollutants are present at a remediation site and determine the most effective technology for removing or remediating each pollutant.

These science workers might spend time outdoors studying the site or have technicians perform the site work. They might spend time in a laboratory testing soil or water samples collected at potential remediation sites.

Job Duties

Biochemists and biophysicists study the biological effects of pollutants and the effect of these pollutants on the local environment. They also study organisms that are used in bioremediation.

Chemists investigate the characteristics of chemicals that have caused a site to be contaminated and those used to remediate the site. When new chemicals are introduced into the soil or water for the purposes of remediation, chemists must ensure that those chemicals do not cause additional harm and will be effective in the removal of pollution.

Chemical technicians assist chemists and other scientists with testing chemical pollutants or with processes for cleaning them up.

Conservation scientists oversee the overall land quality of remediation sites. They work with landowners and government agencies to devise ways to improve the land and safeguard the environment. They evaluate data on soil and water quality and assess damage to the land from pollution. They help to monitor the remediation process.

Environmental scientists and specialists work to reclaim lands and waters that have been contaminated by pollution and work with other scientists and engineers to determine the most effective and safest ways to clean up a site.

Environmental science and protection technicians conduct laboratory and field tests to monitor the environment and investigate sources of pollution. They also conduct tests during the process of remediation to determine the progress of the remediation project.

Geoscientists work with other scientists and specialists to determine the effects and extent of soil pollution and the techniques that would be the most economical for remediation.

Hydrologists determine the water cycle at a contaminated site and the overall effects of pollution on the local water supply. They study ground water, as well as local water sources such as rivers, lakes, and streams, to monitor the flow of contaminants across different bodies of water.

Bioremediation techniques require the use of microorganisms to remove contaminants, and microbiologists determine which organisms would be best for a particular site. They also monitor the progress of the site as the bioremediation is carried out, collecting samples and analyzing them.

Education and Training

Entry-level education for science occupations varies from an associate's degree or comparable postsecondary education for technicians to a Ph.D. for biochemists and biophysicists. A bachelor's degree may be sufficient to enter some of the science occupations, but a master's or Ph.D. is typically required to conduct research.

Scientists must have a variety of skills and important qualities. Computer skills are essential for the majority of scientists because computers are used heavily for data analysis and integration, digital mapping, remote sensing, and the construction of computer models. Scientists must also have excellent written and verbal communications skills, because they must present their findings to other members of a remediation team, including those without a science background.

Earnings

The U.S. Bureau of Labor Statistics (BLS) currently does not have wage data specific to the environmental remediation industry. The table that follows shows wages for selected science occupations in the waste management and remediation services industry group for May 2011.

Green Job Series: Careers in Recycling—Material Recovery Facility Managers

Keeping a constant flow of recyclables collected, sorted, processed, and sold requires a proficient staff of sorters, drivers, mechanics, technicians, machinery maintenance workers—and experienced material recovery facility (MRF) managers to supervise it. This installment of The Daily Leap's green job series describes the job of MRF managers.

Material Recovery Facility Managers

Job Duties

MRF managers keep the recycling facilities working efficiently and safely. They have a broad range of responsibilities, including overseeing site improvements, submitting budgets, and developing long-term goals for the facility. MRF managers might also work with the sales team to identify new clients who might be interested in purchasing recyclables. When it is necessary to deal with the public or press, MRF managers are the face of the recycling operation.

MRF managers are also responsible for recruiting, hiring, and training employees. They evaluate employees' performances and offer feedback to senior managers on how to reward and compensate employees. Finally, because heavy machinery and large vehicles at an MRF can pose a risk to employees, a substantial part of MRF managers' jobs concerns workplace safety, such as providing employees with regular safety briefings and reviewing technicians' inspection and maintenance reports.

Education and Training

Positions for MRF managers may require education beyond a bachelor's degree. Many MRF managers have earned a master's degree in business administration (MBA) or a master's degree in industrial engineering. Management experience, especially in the waste industry, can sometimes be substituted for education. A combination of a graduate degree and several years of experience is ideal.

Earnings

The U.S. Bureau of Labor Statistics does not have data specifically for MRF managers; however, these workers are included in the occupation general and operations managers. The median annual wage for general and operations managers in the remediation and other waste management services industry group was $90,790 in May 2010. The wage is the median annual wage for the United States as a whole; wages vary by employer and location.

Green Job Series: Careers in Recycling—Mechanics, Technicians, and Machinery Maintenance Workers

Recycling operations rely on various kinds of mechanics, technicians, and machinery maintenance workers to inspect and repair the automated equipment in MRFs (Materials Recovery Facility) and to maintain recycling trucks. This installment of The Daily Leap's green job series describes the jobs of mechanics, technicians, and machinery maintenance workers.

Mechanics, Technicians, and Machinery Maintenance Workers

Getting recyclables from waste bins to manufacturers requires different types of workers. Drivers collect the recyclables and transport them to a MRF, at which mechanics, technicians, and machinery maintenance workers work.

Job Duties

Mechanics and technicians monitor and operate the machines in MRFs, including balers (compactors) that shape the recyclables into a form to simplify shipping to and use by manufacturers. They also regularly inspect the machinery and diagnose and repair any problems with the electrical or hydraulic systems of the compactors. They record their work in detailed logs.

Other mechanics, technicians, and maintenance workers are needed to repair and maintain the recycling trucks. They run inspections and diagnostic tests and perform preventative maintenance and vehicular repairs. Truck technicians also document vehicular part usage and repair times. They may be required to make emergency roadside calls if recycling trucks experience problems while out on collection.

Education and Training

Whether they work on machinery or recycling trucks, mechanics and technicians should have at least a high school education or a G.E.D. They should also have at least a year of formal education and experience performing repairs on machines or vehicles. Workers can learn these technical skills through vocational training programs or apprenticeships. While mechanics used to specialize in one area, many now have knowledge of multiple disciplines, including electricity, electronics, hydraulics, and computer programming. Machinery maintenance workers usually receive on-the-job training that lasts for a few months or a year.

Mechanics and technicians are required to pass drug tests and background checks. They should have clean driving records and need to be able to move equipment that weighs up to 50 pounds.

Earnings

The U.S. Bureau of Labor Statistics does not have data specific to mechanics, technicians, and machinery maintenance workers at MRFs. However, these workers are included in the occupations industrial mechanics; maintenance workers, machinery; and bus and truck mechanics and diesel engine specialists. The table below shows wages for these occupations in the remediation and other waste management services industry group. The wage is the median annual wage for the entire United States.

Next week’s recycling industry series installment: Material Recovery Facility Managers

Green Job Series: Careers in Recycling—Sorters

Collected recyclables are taken to an MRF (Materials Recovery Facility) to be sorted and processed. At MRFs, workers unload the recycling trucks, and dump the recyclables onto slow moving conveyor belts. As the recyclables move down the conveyor belt, they are sorted into different groups by their material. This installment of The Daily Leap's green job series describes the job of a sorter.

Sorters

In single-stream recycling systems, many different kinds of recyclables are collected together. Sorters separate the various types of recyclables so they can be processed.

Job Duties

Sorters work along conveyer belts in MRFs. As waste materials come down the conveyer belt, sorters pull out any items that cannot be recycled and should be disposed of. They sometimes work as quality control inspectors and remove unwanted materials from a single stream. For example, they might remove paper products from a stream of plastic containers.

At older MRFs, sorters are also responsible for separating all the different types of recyclables by material type. MRFs are increasingly relying on automated equipment as a faster way to sort recyclables. Even in these plants, however, sorters are necessary to ensure that no stray recyclables fall into the wrong group. Sorters also monitor the waste stream before it reaches the automated equipment to pull items that could damage the machinery, such as garden hoses, from the conveyer belt.

Education and Training

There are no specific education requirements for sorters. Many companies conduct drug tests and background checks on prospective employees. Sorters need to be physically capable of working on their feet for the entire day. They also need strong backs to handle repeatedly bending over to pick items off the conveyor belts. Sorters must have excellent vision to spot items as they come down the conveyer belt.

Earnings

The U.S. Bureau of Labor Statistics does not have data specifically for recycling sorters at MRFs; however, these workers are included in the occupation laborers and freight, stock, and material movers, hand. The median annual wage for laborers and freight, stock, and material movers, hand in the remediation and other waste management services industry group was $23,570 in May 2010. The wage is the median annual wage for the entire United States. Wages vary by employer and location.

For more detailed information on sorters in the recycling industry, follow the Occupational Outlook Handbook link.

Next week’s recycling industry series installment: Mechanics, Technicians, and Machinery Maintenance Workers

Green Job Series: Careers in Recycling—Drivers

Getting recyclables from waste bins to manufacturers requires different types of workers. Drivers collect the recyclables and transport them to a MRF, at which sorters, plant managers, and technicians and mechanics work. Skilled personnel in support roles, such as sales and logistics, are also essential to the recycling industry. Larger recycling firms also employ workers in many other occupations, including management and human resources, but these occupations are not covered in this report. This installment of The Daily Leap's green job series describes the job of a driver.

Drivers

Recycling companies or local governments offering home pickup services employ drivers, also called recyclable material collectors, to pick up and transport recyclables to a Materials Recovery Facility (MRF).

Job Duties

Several drivers usually work together as a team to collect recyclables. One drives the truck, stopping alongside each recycling bin, while the other workers ride inside the cabin or hold onto the side of the truck. At each stop, at least one worker exits the vehicle, grabs the curbside recycling bin, and empties it into the bed of the truck. When the truck finishes its assigned route, the workers return to the MRF where the recyclables are unloaded.

Depending on the type of truck used, workers might have to lift and empty the recyclables from the bin themselves. Other vehicles have hydraulic lifting mechanisms—in either the rear or front of the truck—that can be used to empty the bins automatically. To protect themselves from accidents around the trucks and lift systems, drivers follow detailed safety procedures.

Drivers are required to collect recyclables year-round and in all weather conditions. And, in order to pick up recyclables along long routes, some workers begin shifts as early as 5 or 6 a.m.

Recycling companies that offer services to construction firms pick up recyclable materials from construction sites. Because of the high volume and large size of construction waste, these workers might drive roll-off trucks, which can haul the large dumpsters used on construction sites back to special construction and demolition debris facilities.

Drivers are responsible for inspecting their vehicles at both the beginning and end of every workday. They inspect the tire pressure, fluid levels, safety equipment, and all gauges and controls.

Education and Training

Drivers should have at least a high school education or a G.E.D. To be certified to handle large recycling trucks, drivers must have a Class A or B Commercial Driver's License with airbrake endorsement. Recycling companies prefer drivers who have several years of experience with large commercial trucks.

Drivers need to pass drug screening and background checks. They should have clean driving records. Drivers must also be physically capable of lifting, pushing, and pulling full recycling bins repeatedly throughout the day.

Earnings

The U.S. Bureau of Labor Statistics BLS does not have data specifically for drivers of recycling trucks; however, these workers are included in the occupation refuse and recyclable material collectors. The median annual wage for refuse and recyclable material collectors in the remediation and other waste management services industry group was $29,610 in May 2010. The wage is the median annual wage for the entire United States. Wages vary by employer and location.

Tomorrow’s recycling industry series installment: Sorters

Green Job Series: Careers in Solar Power [Sixth Installment]

Site assessors, electricians, plumbers, and roofers are also involved in the solar photovoltaic installation process, but are not classified as installers. However, they possess many of the same skills as solar photovoltaic installers and often have work experience in these fields. This installment of The Daily Leap's green job series describes some common jobs in solar panel installation and maintenance.

Occupations in Solar Panel Installation and Maintenance

Site assessors determine how much energy can be harvested at a particular location and then make recommendations based on that assessment. Site assessors help determine the best type, size, and layout of solar panels, and help draw up plans for installation crews. Assessors may take readings of sunlight at a proposed location, review weather patterns, and calculate potential costs and savings.

Site assessors are usually hired for commercial projects by companies that are making substantial investments in solar power and therefore want to ensure maximum benefits from the project. Some site assessors may consult with homeowners or solar installation companies on residential projects.

Electricians install and maintain all of the electrical and power systems in a home or business. They install and maintain the wiring and control the equipment through which electricity flows. Electricians are responsible for connecting the solar panels, inverter, and other equipment to a building's power supply. If a new building or house is being constructed with a solar power generating system, electricians may be responsible for installing the solar power system along with the electrical wiring system, or they may be responsible for simply connecting the solar equipment.

Plumbers install solar water heating systems. These systems replace or augment a conventional water heater and must be connected to a house's or building's plumbing. To install these systems, plumbers require specialized training to work with solar water heater equipment.

Roofers install and repair roofs, and they ensure that any cuts or holes made in the roof during the installation of solar panels and mounting racks are properly repaired and sealed. They may also assist with the installation of mounting systems and structural supports.

Education and Training

Site assessors generally have past experience with electrical or roofing work or experience as solar photovoltaic installers. They receive on-the-job training as well as specialized training in the equipment and techniques used to assess a site for a potential solar project. Some formal educational programs are available that teach basic site assessment including how to gauge the feasibility of solar generation, estimate costs, and determine which products to use.

Electricians and plumbers receive training through supervised apprenticeships administered by technical schools or community colleges. Apprenticeships usually consist of 4 or 5 years of paid on-the-job training and at least 144 hours of related classroom instruction per year. Most states require electricians and plumbers to be licensed. Licensing requirements vary, but it is common for states to require between 2 and 5 years of experience, followed by an examination that tests knowledge of trade and local codes. Applicants for apprenticeships must be at least 18 years old and in good physical condition. Drug tests may be required, and most apprenticeship programs ask that applicants have at least a high school diploma or equivalent.

Electricians and plumbers working on solar installation projects must also have specialized training on the systems that they will be installing, or they must work under the supervision of a qualified solar photovoltaic installer. Certification by the North American Board of Certified Energy Practitioners (NABCEP) is required for many jobs, particularly large commercial installations and residential installations.

Roofers typically have on-the-job training and may participate in 3-year apprenticeship program. Many roofers in the solar industry educate themselves through additional training, or they gain experience to become solar photovoltaic installers.

Earnings

The following table shows U.S. Bureau of Labor Statistics data for selected occupations in the Construction of Buildings industry group for May 2010. This industry group includes new residential and nonresidential construction and remodeling. BLS does not publish data for site assessors. The wages shown are median annual wages for the United States as a whole; wages vary by employer and location..

Occupation	Median annual wage

Next week's new green job series: Careers in Recycling

Green Job Series: Careers in Solar Power [Fifth Installment]

Solar photovoltaic installers are key to the process of solar panel installation and maintenance. They use specialized skills to install residential and commercial solar projects. They are responsible for safely attaching the panels to the roofs of houses or other buildings and ensuring that the systems work. This installment of The Daily Leap's green job series describes the job of a solar photovoltaic installer.

Solar Photovoltaic Installers

Solar photovoltaic installers are often self-employed as general contractors or employed by solar panel manufacturers or installation companies. Self-employed installers typically have training and experience with installing solar power systems and are hired directly by the property owners or by a construction firm.

Job Duties

The main component of a solar installer's job is the preparation of the installation site. Before the installation process begins, a full audit of a structure is conducted, including a survey of the existing electrical system and developing safety procedures. The job is then designed based on the characteristics of the structure and the type of system being installed. After the layout and equipment are finalized, the permits are obtained from the relevant governments (local, state, federal, or a combination). If the installers do not do these preparations themselves, they must familiarize themselves with the site before they begin working on it.

Once installation begins, the proper safety equipment, such as a rope and anchor system, must be set up to prevent falls from the rooftop. Often, the building will have to be upgraded to support the solar panels; this may involve reinforcing the roof, replacing rafters, or installing supports to handle the added weight of the panels. The roof must be marked to show where the arrays will be placed, and holes are drilled in the roof to attach the mounting system. After the mounting system is in place, the solar panels can be installed.

Solar photovoltaic installers must be able to work with power tools and hand tools at great heights, and possess in-depth knowledge of electrical wiring as well as basic math skills. When necessary, installers must be problem solvers, able to repair damaged systems or replace malfunctioning components. Safety is a priority when installing solar panels because installers run the risk of falling from a roof or being electrocuted by high voltage.

Education and Training

Solar photovoltaic installers typically have a background in construction or as electricians. There is no formal training standard for installers, but courses are offered by a variety of institutions, such as trade schools, apprenticeship programs, or by photovoltaic module manufacturers.

Many solar installers are licensed as general contractors and many are licensed by the North American Board of Certified Energy Practitioners (NABCEP). Certification, while not necessary, can improve the job prospects of installers, and many larger projects require workers to be certified.

Solar installers may work alongside roofers, electricians, and plumbers in order to learn the variety of skills needed to complete an installation. Many installers enter the field with previous experience in one or more of these fields.

Earnings

The U.S. Bureau of Labor Statistics does not currently publish wage data available for solar photovoltaic installers, but these data are being collected. According to industry sources, solar installers usually have starting salaries between $30,000 and $40,000 per year. Installers trained as electricians or those that are licensed as general contractors can make significantly more. As with any occupation, wages and benefits vary by employer and geographic location.

Tomorrow’s final solar power industry series installment: Other Occupations in Solar Panel Installation and Maintenance

Green Job Series: Careers in Solar Power [Fourth Installment]

Workers at solar power plants install, operate, and maintain equipment. They also monitor the production process and correct any problems that arise during normal operation. This installment of The Daily Leap's green job series describes some of the most common jobs in operations of solar power plants.

Occupations in Solar Power Plant Operations

Concentrating solar power (CSP) plants require more workers than photovoltaic plants; photovoltaic plants can sometimes even be run remotely.

Job Duties

Power plant operators monitor power generation and distribution from control rooms at power plants. They monitor the solar arrays and generators and regulate output from the generators, and they monitor instruments to maintain voltage to regulate electricity flows from the plant. Power plant operators communicate with distribution centers to ensure that the proper amount of electricity is being generated based on demand. They also go on rounds through the plant to check that everything is operating correctly, keeping records of switching operations and loads on generators, lines, and transformers.

Some CSP plants have a secondary source of power generation, such as natural-gas powered turbines, that will generate power at night or when the weather doesn't allow for sufficient solar power generation. Power plant operators are responsible for monitoring this equipment and deciding when to switch from solar generation to the secondary source.

Pump operators tend, control, and operate pump and manifold systems that transfer oil, water, and other materials throughout the CSP plant. Pump operators also maintain the equipment and regulate the flow of materials according to a schedule set up by the plant engineers or production supervisors.

Electricians are responsible for installing and maintaining the electrical equipment and wiring that connects the plant to the electrical grid. Electricians in power plants work with heavy equipment, including generators, inverters, and transformers.

Plumbers, pipefitters, and steamfitters install, maintain, and repair pipe systems. The workers monitor, regulate, and control flow through the pipes using automatic controls.

Electrical and electronics installers and repairers use electronic power equipment to operate and control generating plants, substations, and monitoring equipment. They install, maintain, and repair these complex systems.

Electrical engineers are responsible for controlling electrical generation and monitoring transmission devices used by electric utilities in power plants.

Education and Training

Power plant workers generally need a combination of education, on-the-job training, and experience. Strong mechanical, technical, and computer skills are needed to operate a power plant. Certification by the North American Energy Reliability Corporation (NERC) is necessary for positions that could affect the power grid. Companies also require a strong math and science background for workers seeking highly technical jobs. Knowledge of these subjects can be obtained through specialized training courses.

Electricians and pipefitters and steamfitters must be trained on the specific systems on which they work. They attend specialized training programs and undergo extensive on-the-job training.

Earnings

The U.S. Bureau of Labor Statistics does not have wage data specific to the solar power industry. However, BLS does have wage data for occupations in the Electric Power Generation, Transmission and Distribution industry group, which includes the distribution of electricity generated by solar power plants.
