Name And Describe Four Types Of Renewable Energy Sources

Alternative or renewable energy sources show significant promise in helping to reduce the number of toxins that are by products of energy use and help preserve many of the natural resources that we currently use as sources of energy.

Name and describe four types of renewable energy sources.

Renewable energy often referred to as clean energy comes from natural sources or processes that are constantly replenished. For example sunlight or wind keep shining and blowing even if their. Since it can be built underground it leaves very little footprint on land. Bioenergy is a type of renewable energy derived from biomass to create heat and electricity or to produce liquid fuels such as ethanol and biodiesel used for transportation.

There are many reasons the world is looking for alternative energy sources in an effort to reduce pollutants and greenhouse gases. Solar power can be used directly for heating and producing electricity or indirectly via biomass wind ocean thermal and hydroelectric power. To date there are four main types of renewable energy that we can produce. And the internal heat of the earth can be tapped geothermally.

Geothermal energy is not as common as other types of renewable energy sources but it has a significant potential for energy supply. The ocean provides several forms of renewable energy and each one is driven by different forces. Other alternative energy sources. In addition to the rising cost of fossil fuels and the threat of climate change there has also been positive.

In this context biomass refers to plant matter grown to generate electricity or produce for example trash such as dead trees and branches yard clippings and wood chips biofuel and it also. Renewable energy is becoming an increasingly important issue in today s world. What are renewable energy sources. Types of renewable energy sources include the air biomass solar wind hydro and tidal.

These two types of renewable energy have to be produced using mechanical means rather than by harnessing a natural process. Energy from the gravititational field can be harnessed by tidal power. Geothermal energy is naturally replenished and therefore does not run a risk of depleting on a human timescale. Energy from ocean waves and tides can be harnessed to generate electricity and ocean thermal energy from the heat stored in seawater can also be converted to electricity.
