ENVIRONMENTAL IMPACTS OF RENEWABLE ENERGY 2Abstract The main sources of energy which we are obtaining electricity these days is through fossil fuels. Ie: petrol, diesel, coal, natural gas and etc. These sources are limited so we cannot use them forever, so there is a need of renewable energy to substitute . But these energy resources have a great impact on our environment. These fossil fuels result more harm compared to renewable energy sources by great extent in terms of pollutions, living habitat, global warming emissions and etc. This paper dwells on the strategies which we need to take to overcome the hazardous effects of global warming and utilize the renewable energy sources efficiently.
ENVIRONMENTAL IMPACTS OF RENEWABLE ENERGY 3Today, only a few percentage of electricity is produced through the renewable energy sources. Many research theories have shown that future electricity will be dependent on renewable energy. As per REN21 Renewable 2010 Global Status Report, renewable energy replaces fossil fuels in four different sectors: electricity generation, hot water/ space heating, motor fuels, and rural energy services. Renewable energy is majorly generated using sources like air, sun, biomass, water and heat. These are used as raw materials to generate power. Wind energy is generated using air through wind mills. Similarly Solar energy uses sun, Geo-thermal energy uses heat, Hydroelectric power uses water and bio mass energy uses bio waste. All these processes use large equipment’s and costs high.
ENVIRONMENTAL IMPACTS OF RENEWABLE ENERGY 4Types of Environmental Impacts In order to generate power from renewable sources we need to analyze even the negative environmental impacts of the same, the renewable sources such as wind, geothermal, solar, hydropower, biomass etc. To understand the same we need to know the magnitude of the impact which is in turn dependent on various factors such as the geographical location, the type of technology used and also the type of renewable source involved.
