Resources used specifically for heat.

Renewable Resources
These will never run out and can be used again and again

Biogas in India
Biogas plants convert organic matter such as wood chips or animal poop. This ferments which releases methane gas. This collects in a tank and can be burned to provide electricity for gas or cooking. Over 2.5m in India-provides 57% India's energy

Natural Gas in Europe
Used for electricity for heating and cooking. Collected under the North sea. Most of this has been used up and in '06, the UK imported 50% of its gas supplies. Expected to increase to 80% in 2020.
