If you had the power to decide how to produce all the electricity required for the UK in 2020, how would you apportion the different methods of electricity generation? Would you build more nuclear power stations, reduce the use of fossil fuels? Would you increase the use of green energy by building more wind farms, and how much power would you buy in from abroad. How would you balance these supplies and could you match the supply with the anticipated demand in 2020. And perhaps most importantly of all what would the impact of your decisions have on the average household electricity bill.

If we need an estimated 358 billion kilowatt hours to keep the lights on, perhaps you would favour advocating putting another jumper on, switching off your standby button and increasing the grants for home insulation to reduce the needs for fossil fuels, nuclear energy, renewables and imported energy.

Well now you can find out, with a great little interactive calculator from the BBC, would your decisions meet the emissions targets and keep the lights on.
