Friday was a brave day for Shadow Chancellor Ed Balls to hug a solar panel. Britain had awoken to the - albeit sensationalist and misleading - headline news that households could be paying £170 a year by 2020 to fund renewable energy projects. (The reality being nearly half that cost and overall savings if we get our act together on energy efficiency). But Ed Balls, MP for Morley and Outwood, pulled up to renewable installation company Eclipse Energy in Leeds enthusiastic, engaged and ready to – literally - embrace clean energy.
