Renewable energy facts

Renewable energy is energy generated from natural resources - such as sunlight, wind, rain, tides, and geothermal heat - which are renewable (naturally replenished).

Renewable energy sources are used from ancient history: In 200 B.C., people in China and the Middle East used windmills to pump water and grind grain. Also, old Romans were among the first to use geothermal energy to heat houses.

Until recently renewable energy sources were dominant energy sources. 150 years ago, wood, which is one form of biomass, supplied up to 90% of our energy needs.

Modern interest in renewable energy development is linked to concerns about exhaustion and greenhouse gases of fossil fuels and environmental, social and political risks of extensive use of fossil fuels and nuclear power.

Renewable energy is not subject to sharp price changes because it comes from sources such as sunshine, flowing water, wind, and biological waste, all of which are free. By comparison, fossil fuels are limited in their supply, and their price will increase as they become scarcer.
