Daylight Saving Bill

I am grateful to the right hon. Gentleman for that intervention. He makes a point that I perhaps have not fully thought about, but it is worth putting on the record. I have a serious issue with the proposition that lighter evenings will automatically increase the tourism money coming in to the various isles and decrease obesity—that is, that if it is lighter outside, people might want to get up and go out and exercise. There are various other reasons for doing that, however. On the environmental aspects of changing the clocks, I have an issue with the arguments that changing the clocks will foster a decrease in energy use. We have not been able to find any domestic studies that use empirical data, but we have found studies from the United States that recorded the use of energy during daylight saving time. In 2008, a study was conducted in the state of Indiana. Indiana has 6.4 million inhabitants and, geographically, it is probably approximately the same size as the UK. Its GDP is comparable with that of this country. Indiana is interesting for this argument because certain counties were able to use daylight saving time whereas others were not. The study found that household costs and energy consumption increased owing to people heating their homes in the colder winter mornings, doubtless wanting to rise to a warmer home to counter the feeling of darkness and gloom outside. The empirical data from Indiana say something different from the data we are hearing.
