Solar and wind power are the cleanest energy sources we have for now. The problem is that you have to build massive wind or solar systems to light up a small town, and the cost is still high.<p>Prince Noah is somewhat right. The water molecules hold large amounts of energy that tie their atoms together, and finding a way to extract and store this energy is a good alternative, either for massive electricity generation, or as an oil substitute for automobiles and industry. Plus, the H2 generated by it can be used as another alternative fuel, and the O2 can go either to the atmosphere, or used in hospitals. Using water as fuel, men could be able to stay in space for longer time, and even terraform other planets.<p>A still pollutant, but clean in a certain way source or energy in short scale is the biodigestor. You use your organic, trash, like orange peels, rotten fruits, the potatos you didn´t eat last night, sour milk and litter, putting then in a box or something and let it decompose in there. The methane gas produced in the process can generate energy for one´s house. There´s still production of CO2, but you can get rid of your waste - which would end up polluting the environment -, and doesn´t need to pay energy bills.
