India's Energy: How to Power 1.2 Billion People

India is a country so unique and huge that there are few facts or anecdotes can do justice to the sub-continents dizzying mix of culture, religion and languages. It is a country that simply must be explored, and one that I'm lucky enough to have just spent the past few months travelling across.

On an environmental front it is apparently a country of extremes; streets are dusty and dirty, stagnant water is often filled with malodorous waste and the city air is thick with smog. On the other side of the coin, however, it is a country in transition. Its green-energy growth is faster than almost anywhere else on Earth and, by raw numbers alone, the average Indian lives a far more sustainable life than the average westerner.

The Untapped Potential of Geothermal Energy

You only have to see the steam billowing from Iceland's naturally heated 'Blue Lagoon' to realise the potential geothermal energy has to provide more than enough heat in even the coldest of places.

The 'Land of Fire and Ice' sits atop a plume of magma that lends itself perfectly to the exploitation of geothermal heat. This rather neglected renewable energy source has huge potential, and not just in Iceland. New technologies and growing demand makes geothermal power a possibility all across the world. At the moment, only 5% of global production potential is realised and the sector is growing by 10% each year.
