Sustainable energy is energy that comes from sources that won't become scarce. This type of energy allows societies to meet their current energy needs without causing problems for future generations. There are various sources of sustainable energy. Solar panels can capture heat and light from the sun to energize power grids. Wind turbines can harness kinetic energy from wind to generate sustainable power. Hydropower plants also use turbines to create power, but the energy is generated from moving water, rather than wind. Other kinds of sustainable energy sources include biomass energy, which comes from plants and animals, and geothermal energy, which comes from heat within the earth.‎
