power plants wasting our water?

We all know that there is tons of fresh water on this earth but who or shall I say what is using the most? Power plants. They are using 136 billion gallons of FRESH water every DAY to cool down their plants! now all that could be used for people to drink! Think if we used renewable energy then we wouldn't have to cool down our plants! We could actually stop using nonrenewable energy all together if we had renewable energy power plants we could still give out that energy. We wouldn't need to use that water because solar panels don't generate heat, neither does wind and hydroelectric types of renewable energy. So now we could use all that water for people who are dehydrated. We could let a lot more people live and not have them suffer! Don't you hate seeing those poor kids suffer! So no more nonrenewable energy!
