This link doesn't provide evidence that renewable energy is necessarily to blame for the higher level of pollution. The article says that the increased CO2 emmissions have come from an increased use of coal; coal has become cheaper, and is thus making the nuclear/gas alternative less economically viable.
It is true that Germany has seen a rise in their emmission of CO2, although the article still says the following: ''Germany has reduced its greenhouse gas output 25.5 percent since 1990, exceeding its commitments under the Kyoto Protocol''. That sounds pretty amazing regardless of what appear to be short term increases, don't you think?
Thank you, but the page won't let me read the article!
