Many Green technologies are right on the verge of becoming economical. Many are jsut break even now but would be economical if they were mass produced. Solar cells are about break even and should be money makers in 5 years or so. Wind needs to also get benefits from economies of scale and also newer superconduxting technologies which will make each mill able to generate 10 times more power. I think in the next ten years , many of these things will break through into black ink as costs of alterbnatives come down while costs of fossil based go up. I think their time has come.
