Conserving energy is one of the best ways to improve our impact on the environment. Greenhouse gas emissions (carbon dioxide) are a by-product of energy use and are linked to global warming and climate change. There is also an important connection between energy and water use. It takes water to produce energy and it takes energy to deliver water. Reducing your energy use will help curb climate change AND conserve the water resources it would have taken to generate the energy you saved. It is also a great way to save money on your monthly electric bills.
