Keith has once again written a fascinating article. I am consistently impressed with his well thought out, well researched and compelling arguments for change. This time he tackles energy, how we produce it, how we use it, and how we need to change a lot of those things if we are to make it as a species.
The more significant change has been in the fuel type used in this period. Solid fuels burned at home, like coal and wood, decreased in usage from just over 18 to less than 1 million tonnes of oil equivalent. At the same time natural gas increased from 9 to 34 mtoe, while electricity from the national grid increased from just under 7 to nearly 10 mtoe. Overall, people in the UK have increased their domestic energy consumption by nearly 32%; and this in a land without air conditioning. It is to the USA that we have to go to see some really fascinating figures.
According to the US Department of Energy there has been a massive shift in the way energy used in the home is produced. In 1970 United States homes used 206 million tonnes of oil equivalent in “primary consumptionâ€, meaning that the fuel – such as coal, wood or butane – was burnt in or around the home. In the same year 135 mtoe was drawn from the national grid in the form of electricity. By 2004, the figure for primary consumption had gone down by 16%, reflecting the move away from solid fuels. By 2004, the consumption of electricity had gone up by 160% or, if you like, the USA consumed 2.3 times as much electricity in 2004 as it did only 34 years earlier. The USA consumes a lot of electricity!
Ok, so what has that to do with a washing machine running during the night? For the answer to that, we need to look at the way electricity is produced.
