Name And Describe Four Types Of Renewable Energy Sources

Other alternative energy sources.

Name and describe four types of renewable energy sources. 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. There are many reasons the world is looking for alternative energy sources in an effort to reduce pollutants and greenhouse gases. Wind power solar power hydro power and geothermic power. For example sunlight or wind keep shining and blowing even if their.

In addition to the rising cost of fossil fuels and the threat of climate change there has also been positive. Energy from the gravititational field can be harnessed by tidal power. The ocean provides several forms of renewable energy and each one is driven by different forces. Types of renewable energy sources include the air biomass solar wind hydro and tidal.

Biomass as a renewable energy source refers to living and recently dead biological material that can be used as fuel or for industrial production. 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. Geothermal energy is naturally replenished and therefore does not run a risk of depleting on a human timescale. Since it can be built underground it leaves very little footprint on land.

These two types of renewable energy have to be produced using mechanical means rather than by harnessing a natural process. Solar power can be used directly for heating and producing electricity or indirectly via biomass wind ocean thermal and hydroelectric power. Geothermal energy is not as common as other types of renewable energy sources but it has a significant potential for energy supply. 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.

And the internal heat of the earth can be tapped geothermally. Renewable energy is becoming an increasingly important issue in today s world. As the world reaches its energy crisis we need to reduce our dependence on non renewable energy sources and start generating renewable energy on a massive scale. What are renewable energy sources.
