Green energy is any energy type that is generated from natural resources. Green energy is energy produced from sources like the sun, wind and hydro-electric plants. Green energy is energy that, when used, does not pollute the atmosphere; creating little or no greenhouse gases.

By using energy more efficiently, a green home can help reduce the demand for power and the amount of air pollution generated. The easiest way to make sure a new home or apartment is energy efficient is to look for the blue ENERGY STAR mark, the government-backed symbol for energy efficiency.
