1 Alternative and Renewable Energy Systems

2 Known as the standard for technical training systems in use across virtually every industry and around the globe, Lab-Volt is now using its expertise to provide hands-on training solutions in Alternative and Renewable Energy Systems for Secondary, Career and Technical, Post-Secondary, and Workforce Development educational institutions. Alternative Energy is a natural progression for Lab-Volt. Since the postwar technology boom of the 1950 s, the company has been helping to train the minds and hands of the specialists and technicians who make the possible practical. Lab-Volt has maintained its leadership by combining expertise in virtually all scientific, technological and industrial disciplines with the ability to envision the most efficient and effective means to educate within the training center and classroom environments. Alternative and renewable energy sources are steadily climbing the ladder of environmental and commercial importance as scarcity and expense restrict the supply of non-renewable fuels. Lab-Volt recognizes the special nature of Alternative and Renewable Energy, an industry that combines factors more unique and specialized and having more complicated relationships than most traditional power generation and distribution fields. Lab-Volt s new alternative energy training systems cover foundational, intermediate, and advanced alternative energy technologies, including wind, solar, and solar thermal technologies. This training focuses on the electrical and electronic components at the core of many green energy technologies and covers not only the production of alternative energy, but how that energy translates into common usage. While most power generation requires the creation, management, and conversion of heat energy into motion with most variations simply involving the way heat is produced alternative and renewable sources are far more varied. Many take advantage of the motion already found in nature; others harness nature s own renewable forms of heat and energy. Cap- 2

3 turing and converting that motion or energy often requires very non-traditional methods. Accordingly, development of the Lab-Volt Alternative and Renewable Energy Systems required rethinking the traditional approaches to training, from the need to understand the base science to how, for example, location and environmental issues affect an alternative/renewable energy source s ability to work efficiently or even acceptably. Lab-Volt training systems are proven and trusted worldwide by educators operating in all sectors, including schools and universities, vocational training, government and the military, commerce and industry, and more. Lab-Volt supports all of its products with state-ofthe-art service centers in the United States and Canada, and a comprehensive network of product technicians standing by worldwide. 3

4 Alternative Energy Training Programs Lab-Volt s Alternative Energy Training Program was developed as a three-tiered program. It begins at the secondary education level with 40 hours of Graymark s GREENtech program and continues with hands-on training on our comprehensive Solar/Wind Energy Training System, Model and Solar Thermal Energy Training System, Model These secondary education programs focus on installation and operation, including electrical skills, maintenance and support, and an understanding of the set-up and use of stand-alone (a small renewable energy system that is not connected to the electricity grid) and grid-tied (a small renewable energy system that is connected to the electricity grid) renewable energy systems. *Some of the programs outlined in this brochure are in development and subject to change. 4
