I was a coffee geek for many years, but switched to tea a couple of years ago (long story). So I still have all the gadgets including a dual boiler espresso machine etc. The thing is, if you really want latte/espresso at home, the energy costs are quite high. You need to warm it up for at least 15 minutes. Didn’t run the numbers but it’s not negligible. So not sure if you’re saving the environment much by buying and powering a home espresso machine for a couple of cups per day?
