Continuing the list with another classical element, water holds the honor of being the oldest renewable energy source used by humans. The first hydroelectric plant

Types of Renewable Energy

Renewable energy, also known as clean energy, is produced from natural resources that are generated and replenished faster than they are consumed—such as the sun, water and wind.Most renewable energy sources produce zero carbon emissions and minimal air pollutants. Fossil fuels (oil, coal and natural gas) on the other hand, are finite resources and release harmful

What are the different types of renewable energy?

What is renewable energy? Renewable energy is energy that comes from a source that won''t run out. They are natural and self-replenishing, and usually have a low- or zero-carbon footprint. Examples of renewable energy sources include wind power, solar power, bioenergy (organic matter burned as a fuel) and hydroelectric, including tidal energy.

SummaryHistoryOverviewMainstream technologiesEmerging technologiesMarket and industry trendsPolicyFinance

Prior to the development of coal in the mid 19th century, nearly all energy used was renewable. The oldest known use of renewable energy, in the form of traditional biomass to fuel fires, dates from more than a million years ago. The use of biomass for fire did not become commonplace until many hundreds of thousands of years later. Probably the second oldest usage of renewable energy is harnessing the wind in order to drive ships over water. This practice can be traced ba
