Renewable energy is energy which comes from natural resources. For example, sunlight, wind, rain, tides and geothermal heat which are renewable (naturally replenish). Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun or from heat generated deep within the earth. Lets see various advantages of renewable energy here:
Advantages of Renewable Energy
Renewable energy replaces conventional fuels in four distinct areas:
Hot Water or Space Heating
Rural (off-grid) energy services.
Firstly, once the renewable infrastructure forms, the fuel is free forever. Unlike carbon-based fuels, the wind and the sun and the earth itself provide the fuel. It is free in amounts that are effectively limitless.
Secondly, while fossil fuel technologies are more mature, renewable energy technologies improve rapidly. So innovation and ingenuity give us the ability to constantly increase the efficiency of renewable energy. It also continually reduce cost.
Thirdly, once the world makes a clear commitment for shifting towards renewable energy, the volume of production will itself sharply reduce the cost of each windmill and each solar panel. Further, adding yet more incentives for additional research and development to further speed up the innovation process.
