With the world's fossil fuel stocks running out there is an increasing awareness globally on switching to renewable energy sources. It's perhaps best evident in Sweden, a country which currently meets around 52 percent of its total energy needs through renewable sources.

Other countries which are leading in the use of renewable energy are Latvia (37 %), Finland (36.8%), Austria (32.9%), Denmark (27.8%).

Even though there is an increasing awareness, India still has a long way to go if the country is to switch to renewable energy. As of 2015, only 15 percent of the country's total energy production came from non-conventional sources.

India has however set an ambitious target of producing 40 per cent of its total power capacity from renewable sources by 2030.
