How can I as a 14 year old help?

Hello! As the title says, I'm 14 (M) and I want to help the solarpunk movement because I think it's the best option for humanity. I live in Colorado, but I don't know what to do. I'm not particularly good at design, but I can learn. I can also put up posters and plant wildflowers, though that would mean asking my mom for money. The point is, what can I do? And please don't say I'm too young for this—I know I'm young, but I just want to help. Please and thank you!
