In the modern world, the need for energy is only going to increase with each passing year.
Per capita annual energy consumption :
Qatar uses 223 MWhr per annum and is highest.
US - 80 MW-hr
China 25 MW-hr.
India - 7 MW-hr
Our energy usage will increase 4-5 times in the next couple of decades and this energy has to be generated most responsibly and by green methods.
Comparing the world's largest (China), second largest (US) and third largest economy (India), you will find that there is great scope of growth in the largest and greatest economies of China and India.
