We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
Electricity is considered a very efficient way of energy consumption in part because it is weightless as well as easy to distribute. Electricity is used without creating loss and without creating pollution. Other forms of energy experience loss, pollution or both, such as fossil fuels. At the point where electricity generates, it is a renewable form of energy as well as a clean one. Without electricity, humans would be able to enjoy next to no modern conveniences.
