I live in the south of Spain and I have first-person experience with this - most of these deaths happened to old people who, despite their really good pensions, would rather die of heat stroke than install and turn on an air conditioner. Some really think they are going to be buried with their money.

You could cut these deaths to basically zero if the government installed the air conditioners and they didn’t have to pay for the electricity. Just to be clear I’m not advocating for this.
