Sustainable energy. Conceptual image of a tree in a light bulb, representing the sustainable generation of power. This is the use of methods to generate electricity that minimise their impact on the environment by being sustainable. Examples are solar power, hydroelectric power, and wind power. Non-sustainable energy generation includes the use of fossil fuels, as in power stations that use coal, oil or natural gas.
