Reuters: Ambitious Renewable Energy Targets Flawed

Ambitious targets for renewable electricity in the medium-term are likely unfeasible, given they demand forced, early write-offs of fossil fuel power plants and may downplay rival shale gas and the unpredictability of wind and solar power.

The European Commission on Thursday unveiled its "Energy Roadmap 2050" laying out options for making sweeping carbon emissions cuts through a combination of efficiency and renewable energy and other low-carbon technology.

At present renewable energy (mostly hydropower) accounts for about a fifth of both global and European Union power generation. HERE
