Another point which I think is important is the related infrastructure for renewable power plants – particularly transmission lines.

It seems that so many renewable energy ‘dense’ sites – like geothermal and wind – are concentrated in areas away from major population sites. Hence the necessity of constructing transmission lines adds considerably to the overall cost of the project (I’m thinking particularly about Geodynamics). In contrast an expansion of a coal-fired power plant (or new one) does not face this cost as it can be sited near existing infrastructure.

I don’t know how much it would cost, but I think it would be good if the Govt could partially subsidise, if not completely, the cost of transmission lines to the national grid provided the renewable source was of a particular capacity.

Also have a look at the proposal of Dr Gregor Czisch: http://www.independent.co.uk/environment/climate-change/windfuelled-supergrid-offers-clean-power-to-europe-760431.html

Anyway – keep up the good work!
