A look at the basic relevant concepts quickly shows that offering
grants for solar PV or HW is an unsuccessful practice in terms of
either money or energy saving.
In terms of money saving, hot water will be a relatively long term
investment and electricity a very long term investment. Both at
current prices.
In terms of energy saving, it will be a much better investment
especially hot water. Of course some claim that the energy used in
construction and installation is never recovered. Much the same
claims are made about wind farms, but these claims are false too.
The same is also true of carbon dioxide savings.
The same stuff seems to get rehashed every time this comes up. I cba to
rewrite it.
