I believe Solar panels have storage compartments to hold energy, if you can afford enough, you want have to worry about no sun for the day. Wind energy is yet again not a worry. Ever see a picture of windmills in large fields, like an orchard of trees? Water pollution is an issue, but if you take steps to filter the water before, duriong and after the energy exchange, whats the issue with it?
Right, but then not every country in the world is willing to use the latest technology.
As for water pollution, I think I might be using the wrong term here, but I remember reading somewhere that dams (you need them for water turbines) can cause wildlife in and around the river to be affected. Floods, water temperature rise, and waste. Heat pollution? If I remember correctly?
Yes, we are trying to reduce pollution, but just looking at the climate and weather patterns from the past 50 years, I think we're already too late (gee, that sounds depressing). No, it certainly won't be a 2012 apocalypse with great big flood and supervolcanoes, but I bet that in the next 10 years, the weather is gonna get freakier regardless of our efforts to reduce pollution.
