Yes, and no. It's not as easy. We do need to switch to renewable energy if we want to solve the crisis, but more importantly we need to stop using fossil fuel. Unfortunately, if you look at history, every time we discovered a new energy source like solar, hydro or wind, we never actually stopped using the older energy sources. For example, if you look at coal, we use more coal today than ever before in history, despite having found "better" options like petrol.

So yeah, it cool that we have new ways to build solar panel, but unless we actually stop using fossil fuel, then it won't stop the crisis.
