UPDATE 16 May 2013: We've got a date! The key vote is scheduled for Monday 3 June. If you haven't already contacted your MP about this, now's the time!
The Energy Bill, at a jaunty angle
1. What's going on?
MPs are voting on the Energy Bill, a wide-ranging policy that sets the long-term course for our energy system.
There's a (lovable) rogue amendment on the table, which would set an upper limit on carbon emissions from electricity.
MPs will vote on this separately, and if it passes, we'll be charging our hoverboards with nearly zero-carbon power by 2030 – good news for pretty much everyone who doesn't sell oil for a living.

2. Why that matters
Ok sure, there's plenty of obscure green targets you could get excited about – let me tell you why it's worth getting excited about this one in particular.
Right now, most of our electricity comes from a fleet of knackered old coal and gas-fired power plants, and they need replacing ASAP.
What comes next? It's basically a choice between clean energy sources like wind and solar, or another wave of pollution-tastic gas fired power plants.
