Cheapest power source from nature

Solar energy is set to become the cheapest source of electricity in many parts of the world within the next 10 years, with the cost of photovoltaics (solar panels) continuing to decline.

In fact, in some parts of the world, solar energy would become cheaper than the heavily subsidised fossil fuel energy, says a report.

India plans to install 100GW capacity of solar power by 2022, while China aims to achieve 100GW of solar power capacity by 2020
