What’s energy efficiency and how much can it help cut emissions?

The Guardian’s Ultimate climate change FAQ provides a useful and succinct explanation of the term energy efficiency.

“Energy efficiency means using less energy to provide the same service. For example, a compact fluorescent bulb is more efficient than a traditional incandescent bulb as it uses much less electrical energy to produce the same amount of light. Similarly, an efficient boiler takes less fuel to heat a home to a given temperature than a less efficient model.”

The article was written by Dr Tamaryn Brown, Professor Nilay Shah and Professor David Fisk, Grantham Institute for Climate Change and Chemical Engineering, Civil and Environmental Engineering, Imperial College London, in collaboration with the Guardian newspaper. It can be accessed in full here.
