Nothing geeky. Just the basics. First, educate yourself. For example, food waste is a huge contributor to carbon output. So I don't ever throw out food anymore.

Nothing geeky. Just the basics. First, educate yourself. For example, food waste is a huge contributor to carbon output. So I don't ever throw out food anymore. Anything remotely close to going off goes in the freezer for soup. Since I buy groceries almost every day, I don't have much to keep track of in the first place. I work remote. I walk and ride my bike everywhere and rarely use a car. I avoid disposable plastic whenever possible. I'm intentionally not a very "good" consumer. For example, I have about ten t-shirts and two dress shirts. They last me years. That's my entire wardrobe for shirts. Cutting down on air miles has been hard because I love travel, but I have done it. It also doesn't hurt that I already live in a country that is over 80% renewable when it comes to electricity. I also try to encourage others to take personal responsibility. IMO, this isn't a technology problem. It's a cultural problem. We already have everything we need to fix this. It's a matter of public will.
