According to a report by the European Commission, two thirds of the new PV panels installed in 2011 were in Europe. Enough, in fact, to power the whole of Austria, although spread around the continent the effect is rather less impressive.
Still, it is good news. China is apparently the fastest growing manufacturer of PV, but European countries are at least exporting manufacturing equipment there. And growth rates of between 40 and 90 per cent a year worldwide since 2000 are encouraging. We may not be doing much that is right in relation to the environment, and PV may not be the best solution all the time,but at least we are taking it seriously.
