Renewable energy sources are considered environment friendly and capitalize on the natural processes to generate power. They are alternate and cleaner energy sources to help negate the impacts of global warming and pollution. These power generation techniques are renewable sources of energy that does not exploit our earth’s natural resources.
Solar power: the foremost renewable source of energy
PV or Photovoltaic solar power makes use of the rays of the sun to produce electricity. Solar power is the fastest growing renewable energy source gaining a lot of ground. PV may be used for small to medium sized applications. The installation of solar panels in residential and commercial complexes has expanded in the recent times.
Hydroelectricity: the power generated by hydropower
Here the electricity or power is generated through the gravitational force of flowing or falling water. It is indeed the most widely used renewable energy form. After the hydroelectric complex is constructed, there will be no waste. Around 19% of the electricity in the world is generated by hydropower.
Geothermal is the most powerful and effective way of extracting renewable energy from below the surface of the earth with natural processes. This medium may be used to produce energy in large scale or small scale. Again, geothermal power is environment friendly, cost effective and reliable.
Wind Energy: the clean energy source
The wind energy has been used since centuries to drive the windmills and to sail the ships. Now, the wind energy may be captured by the wind turbine in order to generate electricity.
