Like Simon Jenkins in the Guardian today, I am utterly confused by the direction of UK energy policy; wind is risible nonsense, so fatuous an answer as a credible energy source that the only rational explanation for those that support it is bribery and corruption on a widespread scale. Tree-hugging lunatics distort the science, powerful industry lobbies such as that for the hugely ineffective Solar PV distort the subsidies. And Westminster and Whitehall just spin about in dizzy confusion not knowing what day of the week it is. Anyhow, here's my take on the options for the UK (experts please pile in ...):
Nuclear - the risk is worth the gain. Serial construction of a standard design would lower costs and there are plenty of places in the world to dump the waste (Mariana Trench looks good to me)
Gas - Methane from the ground is good and there seems to be lots of it, even in the UK
Coal - Coal's greatest potential is through pyrolysis to make Hydrogen and Methane in quantity, and we've got huge reserves
Then the best of the renewables
Solar - through the heating effect of the Sun of the Earth's surface. A couple of metres down in the UK the temp is a constant 14deg - masses of heat that can be extracted via GSHP. I've done this on a commercial scale - it works very well. Solar Thermal and Solar PV are no good - too variable, yields too low and costs too high.
Lunar - The power of the tides is immense, and a diurnal range of up to 7m in the SE as billions of tonnes of water pushes up the Western Approaches twice a day means it's not just the Severn that could provide feasible installations. Good for the UK, France, Ireland etc but no good for inland States.
Then the worst
Biomass - there's simply not enough of it, but burning wood is good for the environment.
Wind - a risible and nonsensical solution that suggests massive corruption somewhere - follow the money
Biofuels - Corn to Ethanol is a stupid idea unless you intend to drink it. Bacteria that convert household wastes to diesel have some promise, but too small scale to have an impactFairy-power, ley-lines, henges - I suppose sixty dancing fairies doing the Rumba can provide enough power for an average new-age Yurt but the trouble is keeping the little buggers at it. Etc.
