Why do we need wind energy?

The world is getting hotter, in fact by 1°C on land over the last 100 years, and the overwhelming concensus of scientific opinion is that human activities, particularly the emission of greenhouse gasses, are the cause.


The energy sector is by far the biggest source of these emissions, both in the UK and globally, and if we are to tackle climate change it is clear we need to move away from burning limited fossil fuel reserves to more sustainable and renewable sources of energy.


As well as being good for the planet, this is also good for economy as it reduces the UK's dependency on oil and gas imports - improving the balance of payments while also increasing energy supply security.


Almost uniquely there is cross-party political concensus that we need to see more renewable energy and the Government has set a binding target for 20% of the UK's electricity to come from renewable sources by 2020.


Wind power is a well proven and cost-effective technology and expected to be the main way in which industry responds to the Government's targets - so becoming an important source of electricity in years to come.

Over 80% of the world's energy comes from fossil fuels, a finite resource. Annual oil and gas consumption now far outstrips the new discovery rate and reserves are only sufficient for 40-60 years. Read more»
