The world runs on energy- the change from animal to wind power has changed the face of the Earth forever. Life as we know it today is impossible without the use of energy. From transport to communication, from agriculture to medicine, from cradle to grave, modern man is totally dependent on energy to provide the goods and services he needs. As a result, energy resources are now more important than ever before.

Fossil fuels, which have been instrumental in taking mankind from an agrarian society to a modern technological and information-based society of the 21st century, are depleting. This has brought into light the need for newer energy sources.  The world is conscious of the need to find new and renewable sources of energy, but finding the right solution is not easy- everything comes at a price. With the present state of scientific development, almost every source of alternate energy has one or more negatives that balance out the positives.
