Photovoltaics (PV) is a solar power technology that uses solar cells or photovoltaic arrays to convert energy from the sun into electricity. Most systems are tied to the utility grid. On sunny days you produce energy and your utility meter may turn backwards if you produce more electricity than you use. During the night or on cloudy days, your meter turns forward, using your credit and then buying power from the utility company.
Nearly half the solar energy our planet receives is absorbed by the ground. As a result, below the surface, the earth remains a constant moderate temperature year-round. This provides an ideal source for heating and cooling your home.
Geothermal systems use a sealed underground piping loop filled with circulating water and an ultra high-efficiency heat pump to exchange heat between your home and the earth. In the winter, the earth is your source of heat. In the summer, the earth is your source of cooling.
Geothermal systems are approximately four times more efficient than traditional heating systems. Little or no greenhouse gasses are created and no carbon monoxide is released making geothermal a safe and sustainable option.
Wind power is the conversion of wind energy into more useful forms, usually electricity using wind turbines. Wind energy provides free and clean electricity.
A wind turbine resembles a propeller engine from a sleek modern aircraft mounted on a tall tower. As the wind blows over the turbine blades, the turbine revolves and generates electricity you can use in your home or business.
