The [[environmental movement]] has emphasized [[sustainability]] of energy use and development.<ref>Sustainable Development and Innovation in the Energy Sector.

Springer, December 5, 2005.</ref> [[Renewable energy]] is sustainable in its production; the available supply will not be diminished for the foreseeable future - millions or billions of years.  "Sustainability" also refers to the ability of the environment to cope with waste products, especially [[air pollution]].  Sources which have no direct waste products (such as wind, solar, and hydropower) are brought up on this point. With global demand for energy growing, the need to adopt various energy sources is growing. [[Energy conservation]] is an alternative or complementary process to energy development.  It reduces the demand for energy by using it efficiently.
