This open source project visualises the emissions of electricity generation across Europe along with the potential for renewable energy.
By playing around with the tool available on the website you can discover how wind and solar power have already become a significant part of the energy mix in most European countries.

This is showing the great improvements being acheived in the carbon footprint of the electricity we use. Just a few years ago in the UK the average was over 500gCO2eq/kWh.
Note that the values used to reflect the carbon footprint of electricity generated by Nuclear power are still not agreed worldwide, and the figures used on this of only 12g may be too low.
