Not sure about solar as here in Scotland we only know of the sun from reading about it in books and hearing the strange tales of travellers from far off lands - such as England.
But the green energy "incentives" here are going to cost us
£300 a year, when we have had increases in the 10-20% range annually now for about 2-3 years. My own energy supplier has just anounced another 15% increase partly to pay for this stuff.
Wind farms seem to hoover up government cash for little return (less than 1% of demand here last year).
And now we have
Thorium - which I don't understand, yet.
I like the idea of wraparound solar and if the printed process makes it cheaper than all to the good. I wait on the fence for a convincing case though.
EDIT - Our own Prime Minister's father in law makes
£1000 a day from wind farm subsidies. Madness, sheer madness.
