You want your own website to be green?
There are a few steps to take that really don’t hurt and are done pretty quickly. Start with eco hosting and then go further. Or start with compressing all your images. I’m happy to support you on that journey! Why? Because I want the internet to be less of an energy eating monster and more of a loving network. For the planet and our climate.
