Renewable Energy - Introduction

 

Renewable energy is the most discussed, most emphasized and most developing topic in the world now-a-days as it is the only option which can solve the two most concerning topics of mankind (1) Energy security (2) Climate Change:

In this blog I have provided introductory information on renewable energy and different types of renewable energy sources and have discussed wind energy in detail.

The basic definition of renewable energy is "any sustainable energy source that comes from natural environment".

The four basic aspects of Renewable Energy are:

• It exists perpetually and is abundant in the environment;
• It is ready to be harnessed and inexhaustible;
• It is a clean alternative to fossil fuels;
• “energy that is derived from natural process that are replenished constantly”

Let’s have a look at the contribution of Renewable Energy in the world energy production.

The above chart is prepared using data provided by International Energy Agency.

Following are the major renewable energy sources

      

• Hydro Energy
• Wind Energy
• Solar Energy
• Biomass Energy
• Tidal Energy
• Geothermal Energy
• Wave Energy
• Bio-fuel
• Bagasse

 

Talking about the India, India has the installed capacity of renewable energy sources as per the following table;

Renewable Energy Source	Present Installed Capacity
Wind	10200 MW
Small Hydro	2100 MW
Bagasse	750 MW
Biomass	620 MW
Solar	2 MW
Total Installed Capacity	13672 MW

The above data are as per Ministry of New and Renewable Energy Sources of Indian Government.

Currently Wind Energy is the fastest growing Renewable Energy Source on which I will discuss in my next blog. And in next blog Solar Energy ,another fastest growing renewable energy source will be discussed.
