Thanks for that Rob very informative.

I have no idea why in these discussions it always gets be presented as an either/or case.

Wind Farms and wind turbines are most definitely NOT the answer, neither are wave and tidal power generation schemes. Geothermal looks attractive but expensive and very technically challenging.

The answer will be a combination of nuclear, oil, gas & coal powered generation and the renewables. We have to use the resources that WE have.
