Baked potatoes

Much better in the oven than the microwave, of course, but you really have to give them at least an hour and a half [changed from two - see comments].

If you have an electric oven, say one of 4,000 watts, this means power consumption of 6kwh. Apparently not only does this cost about 60p in electricity, but chucks out roughly 3kg of CO2 (it depends on the mix of sources of electricity generation, but this is the UK average).

This is turn is equivalent to driving 11 miles in an average UK car, or 18 miles in a Toyota Prius (or about 3 miles in a Lamborghini, which is not so good).

Any of the above calculations might be wrong - I'm not sure if electric ovens are 4kw - I saw in the US they are about 5kw and I've downscaled it a bit, but I'm not sure if that's the right thing to do.

Anyway until someone tells me other, a baked potato = 11 miles round-trip in a car.
