Wind turbines and solar panels are both sources of clean energy
Hydroelectric dams use rivers to produce energy

Clean energy is energy that is produced through means that do not pollute the atmosphere. [1] It can also refer to renewable energy sources that do not create environmental debt: using up resources that cannot be replaced or severely damaging the environment so that future generations must solve problems created today. [2] [3] Currently, most (all?) known energy production methods have some type of environmental impact, so clean energy describes the energy production methods with the least amount of impact on the environment. The primary sources of clean energy are solar energy, hydropower, and wind power.

  • solar energy uses the heat of the sun to produce energy.
  • hydropower uses the power of water, usually rivers or tides, to generate electricity.
  • wind power uses the power of the wind to turn turbines; this motion produces electricity.

Biomass, which is turned into biofuels, is also sometimes considered clean energy, although some debate exists as to whether biofuels are actually environmentally friendly. (see: Biofuels for more details) One problem clean energy supporters face is the lack of supporting infrastructure for clean energy. The current electric grid is currently set up to accommodate fossil fuel energy production. In order to effectively use clean energy more widely, the grid would need to be reconfigured to allow for the transport of energy from its source to where it will be used. [4]
