  •  Yes most power plants do use lots of water (14+ / 0-)

    That's why we need to go for solar and wind in a big way, ASAP.

    •  Except we have this problem called Base Load (2+ / 0-)

      Solar and wind cannot overcome this.  Folks that live "off the grid" can explain the sacrifices they make better than I can, but solar and wind are not stable, 24 hours a day, sources of electricity for an industialized society, no matter how much we wish it to be so.  Stable voltage/frequency on a wide area grid, under varying loads, is not as easy to maintain as you might think.

        over a wide enough area. IE, a windmill over your house will not run 24x7 but thousands of windmills across the US certainly can be expected to.

        In addition, solar and wind can be used to create various kinds of 'batteries' - not the conventional sort, but for example pumping water uphill when there is surplus power, and then letting it flow through a turbine when power is needed.

        Solar thermal plants concentrate sunlight on vats of liquid that boil water to create electricity. By filling your vat with some fluid other than water, you can create and store enough heat to continue generating power through the night.

        Fry, don't be a hero! It's not covered by our health plan!

        •  Exactly (0+ / 0-)

          We can also use current and tidal forces to generate electricity.

          There are many ways to store the energy, depending on the terrain and available resources.

        Where have I heard that before?

        Oh, yeah, from people that want to push things like nukes.

        That can be solved, and has been, with a large area of alternatives, current and tidal power generation, along with storage  in many different ways.

        We have the technology, we just need to do it.
