Solar Day 18 June

18 June.... well in the Northern Hemisphere anyway. See the page to read more about the mission of Solar Day. (it is 18 November in the Southern Hemisphere). DNC writes:

Face it....
• we have perhaps 50 yrs of declining oil and gas....
• if it wasnt for the smoky emission and the destruction of open cast mining we also have a lot of coal remaining below - enough for perhaps a couple of hundred years...
• but shouldn't we consider that the life of the Sun is measured in billions of years? Enough sunshine lands on the earth every day to cover our entire needs many times over if only we can develop the technology to capture and distribute it.

All energy sources cost something to exploit, I would prefer to see the money spent on a field full of Solar panels than a field converted into an open cast coal mine. (yes, people of Castle Donington!)
   Coming back to our own houses, what can we do? The upfront cost of a 4 kW PV array is only a fraction of the value of the house it goes onto, but will give a lifetime of cheap energy without emitting carbon, and an income for the first 25 years at least, more than enough to pay off the first cost.
   If the German government can project that the growth of renewable energy may be enough to decommission their nuclear power stations in 20 years, then that's an encouragement to us to try harder!
