If you don’t have a green job, you may soon be left in the dust. Green-collar jobs have experienced a 9 percent increase in the last 10 years. There’s no turning back now.The Obama Administration has proposed a $10 billion budget for the U.S. Environmental Protection Agency to develop new environmental programs aimed at protecting the country’s ecological resources, while creating new jobs. Additionally, President Obama promises to spend $150 billion over the next decade to create 5 million green-collar jobs. The American Recovery and Reinvestment Act has siphoned billions of dollars into the development of renewable energy. Green building will support an estimated 7.9 million jobs by 2013 and the American Solar Energy Society predicts that renewable energy and energy efficiency will be responsible for 8.5 million new jobs in the years to come.Four green jobs experiencing growth include: geothermal installers, environmental specialists, hybrid automobile specialists and OSHA safety-trained workers.Accredited geothermal installers install, operate and maintain geothermal systems. Geothermal is a renewable form of energy that doesn’t add pollution or greenhouse gases to the atmosphere because fossil fuels don’t combust during its operation. The extreme heat trapped in the earth core’s liquid rock creates naturally occurring hot water and steam, which, when close enough to the surface, can be piped to generate electricity. These systems draw from beneath the ground where the temperature is roughly 60 degrees year-round, and the process is used to heat and cool buildings.Certified environmental specialists protect and preserve the natural environment and human health. They address problems associated with drinking and surface water quality, solid and hazardous waste storage and disposal, indoor and outdoor air quality, radiological health, occupational health, system ecology (interrelationships of organisms and their environments) and sanitary hygiene. Environmental specialists collect and research hazardous samples, record data, prepare reports, maintain monitoring gear and provide support to engineers and scientists. These specialists work in the fields of environmental management, public relations, landscaping, food protection and more. Regulatory and public health agencies, industry, utility companies, engineering firms and universities all seek professionals trained as environmental specialists.Hybrid auto specialists work with hybrid cars. These vehicles address the problems of high gas prices and the greenhouse effect caused by our gas-guzzling society, by achieving 20 to 30 more miles per gallon than the standard automobile, which results in improved fuel economy and lower emissions. Most car companies have announced plans to manufacture their own versions of hybrid vehicles in the near future, which means this technology will continue to advance.OSHA safety personnel understand the basics of occupational safety and health. They recognize health hazards that may be present in the workplace and offer prevention measures. OSHA training programs are intended for workers, safety directors, foremen and field supervisors in construction and general industries. Those who undergo training obtain a Department of Labor completion card.The United States is retooling its workforce to meet the demands of the burgeoning green economy, and even more green jobs will soon await us.
