Comment on: Giant heating system at eco-village
As they do mention here, and is standard for most geothermal heating systems, excess heat is returned to the rocks and in summer the unit is 'reversed' to perform an air conditioning role thus mainaining temperature equilibrium. Initially the costs per KH/h are higer but if you factored in the rising cost of any fuel reliant systems over the design life then the current examples provide better value for money.

Comment on: Government plays-down energy blackout predictions
Wind power works fine with up to 20% contribution in countries such as Denmark which have a much smaller wind recourse than the UK does. The key is in sensible integration with current energy supplies. The wind also happens to (typically)pick up at different times to the tide coming in and out. If there happend to be a barrage, lets say, across the Severn(?) and maybe also the Humber this could produce 10% of demand at different times of day. If we learned to use a bit less energy then we wouldnt need as much power. The people who cause the problems are not the 'greens' or the Taliban they are the people who seem keen to slam any scheme that is not their 'ideal'. Rather than saying "I like wind so Tidal is rubbish" or "I like nuclear so everything else is rubbish" why dont we say "We have a problem with energy supply, what feasable recourses do we have that we can utilise that also can contribute towards our renewables obligation and stop the country getting fined whilst creating a robust energy supply infrastructure that can be used as a world wide example of good practice that illustrates that the UK's civil and electrical engineers can all work together nicely and come up with good solutions to our problems" Just a thought!

Comment on: Northwest tidal power to rival Severn Barrage
Agreed, If the researchers can work in conjunction with and not as oposition to the Severn project there could be pottential to provide upto 10% of UK demand via renewable tidal recourses.
