The Basics: How Does Solar Energy Work? Every minute of every day, enough of the sun’s energy reaches the earth to meet the world’s energy demand for an entire year. Using photovoltaic technology through solar panels, solar energy is created by converting the heat and light that comes from the sun into electrical energy. Each solar panel is made up of many solar cells containing both a positive and a negative layer. Much like a battery, these layers generate an electric field. As the sun’s energy is absorbed by the cells, electrons are created and then travel toward the bottom of the panel and exit through a connecting wire. This flow of electrons produces electricity, which can be used in the same way as electricity generated by other non-renewable energy sources. For the cost and eco-conscious consumer, "going green" is more than just a fad. The winds of change have ushered in better, more cost-effective and sustainable resources. It’s no wonder wind power is becoming the fastest growing energy source in the world. Renewable, low cost, and non-polluting wind turbines provide an affordable solution in both rural and urban areas. The Northern Tool Wind Power Buyer’s Guide offers you all the info you’ll need to tap into this exciting power source.
