Cooking advice
Buy Local Food : ...but at the same time, figure out what makes sense. It is more energy efficient to raise lambs in New Zealand and ship them to the UK than to raise them in the UK, because New Zealand lamb farming is more energy efficient. It is also more energy efficient to buy produce raised in Spain, than produce that has to be grown in greenhouses in the UK. Baby steps require figuring out which things make sense and which don't.
Buy Local Food : The most local food of all comes from your own garden. Plant a new garden, enlarge the one you already have, or extend your growing season by using row covers and cloches.
Kitchen Tip : Even though they are like magnets for spills, keep stovetop reflectors clean. They will reflect heat better and save energy. If you need new ones, buy quality. The best on the market can save as much as 1/3 of the energy used with inferior reflectors.
