THE first thing I did was turn off the lights. Then I unplugged everything. On reflection, I reconnected my fridge. Next, I made a list of all the other ways I consume energy.

Rocketing fuel prices precipitated by Russia’s invasion of Ukraine and the transition to renewable sources to limit global warming have focused people and governments on reducing consumption. With this in mind, I wanted to see whether I could drastically cut my energy use. I had read that, in the 1990s, Swiss researchers calculated that just 2000 watts per person would be enough for everyone to live sustainably and still have a good quality of life. So that became my target. This was the first day of a personal, month-long “2000-watt challenge”.
I used an online calculator – once I got the Wi-Fi back on – to estimate my current energy use. In the US, each person consumes energy at a rate of 8600 watts on average. I didn’t think my lifestyle was particularly extravagant, so I was surprised to find I use even more than that. Clearly, I had a long way to go. …
