To those who think a low CO2 economy is dead easy.
As you admire that wind farm nearby consider that in each of those wind turbines is a rare metal. This metal has to be refined in a very inefficient and dirty process resulting in some slightly radioactive waste not to mention the near slave labour used to extract it from the ground in the first place.
Oh and the mines themselves are likely to be in China so the material has to come 1/2 way round the world anyway before it can be used.
Anyway, at the end of the day you can admire the zero CO2 (if you ignore the bits above of course) production of about 0.1-0.9% of the peak demand of electricity with the full, satisfying knowledge that there is...
...99.9% of conventional and nuclear power stations to back it up when it isn't working.
Which is quite often.
