1) If you buy just one new appliance in 2010, make it a really efficient fridge-freezer. The improvements in the energy use of the best fridge-freezers have been really impressive in the last few years. If you have an old refrigerator, it may be responsible for as much as a sixth of your electricity bill. A good new machine might use less than a half as much power, particularly if it is not too large. A second benefit is that by choosing to buy a really efficient refrigerator you will be sending a clear signal to the manufacturers that energy consumption matters. An impressive new web site – www.energytariff.co.uk – allows you to compare the electricity used by almost all the appliances currently in UK shops. You can make well-informed choices from your computer.

I think that once people understand the great risks that climate change poses, they will naturally want to choose products and services that cause little or no emissions of greenhouse gases, which means ‘low-carbon consumption’. This will apply across the board, including electricity, heating, transport and food. A diet that relies heavily on meat production results in higher emissions than a typical vegetarian diet. Different individuals will make different choices. However, the debate about climate change should not be dumbed down to a single slogan, such as ‘give up meat to save the planet’.
A study commissioned by the UK Food Standards Agency concluded that:
there is little, if any, nutritional difference between organic and conventionally produced food and that there is no evidence of additional health benefits from eating organic food.
Yes and no. What the study actually shows is that organic food typically does have higher levels of important nutrients but the high degree of variability in the measured levels means that we cannot be 95% sure that these higher levels are not the outcome of chance. The Food Standards Agency and the report’s authors have misled people interested in this topic and should revise the summaries of their work.
