The gist is to try and make better purchases, while being practical and not having a zealot mindset about it.
In fact, here's my complete product list for your consideration and, no doubt, critique. Will say this: I'm 46, everyone in our house drinks coffee, I have tried a fairly wide variety of coffee preparation methods, and my daughter has been a barista at 3 places, including one far, far away. She helped source all this, and purchased another set of the exact same things when she went to college.

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?
