Actually wind and solar has a lot of problems of its own. Solar for instance produces a lot of e-waste (if you use the photovoltaic panels) while windmills block bird migration routes, produce sound pollution, and reduce the skylines aesthetic. So, in my opinion, renewable energy is good, but its not that good YET, thats why we should focus more on reducing energy consumption and slowly building up the renewables compared to blindingly building renewable powerplants.
