Offshore wind may provide the answers the Tories seek.
The Conservatives will have to meet their climate targets somehow, whether by fracking or offshore wind.
All in for renewable energy.
Labour's green jobs numbers add up, but the picture's less clear on fracking.

Thorium has several advantages over uranium nuclear power, but it also has its drawbacks. However, the question remains whether it would be the right technology should Australia choose to go nuclear.
Peak power use is also a busy time for young families.
A key plank of the Australian Government’s draft energy policy is to reform electricity pricing so that it more accurately reflects rises and falls in peak demand. New tariffs, such as time-of-use (TOU…
