What are Other Examples of Renewable Energy?
Naturally produced by the Earth's climate and geography, wind energy is pollution and radioactive-free. In the past, wind machines were primarily used in mechanical ways, such as to pump water. Modern wind turbines can generate electricity, providing energy for both residential and commercial buildings.
Similar to the winds, the Earth naturally produces flowing waters. Water energy, or hydropower, was used in the past to operate mechanical equipment. As water flows, modern turbines convert energy
Hydrogen is the most abundant element on the planet. Hydrogen itself is a simple element, but it doesn't occur naturally as a gas. It is always combined with another element. Oxygen, for example, is combined with hydrogen to make water. Once separated, hydrogen can be converted into electricity or burned as fuel.
Biomass is the organic matter that makes up plants and trees. Sunlight is absorbed during photosynthesis. Some of the sunlight remains inside plants and trees. This form of energy is biomass. Biomass can be used to produce heat, electricity and transportation fuels.
Geothermal energy is heat from deep within the earth. Decaying materials produce energy that can be extracted and used to produce heat and electricity.
