Wind and hydro? We already know about the long term problems with hydroelectric dams. There is a serious movement afoot to tear out some of the dams on the Columbia and elsewhere. The environmental consequences of dams are serious. Or were you referring to tidal-hydro? That technology has the same problem that wind power does -- there are too few practical locations for producing power using current technology.
We use a lot of wind power in Colorado and Wyoming, but we‘ve learned is that site selection is critical and that the initial costs and upkeep of wind farms are major expenses -- rivaling the costs for a power plant. Though it seems strange to anyone familiar with Wyoming, there are darn few places where the wind blows steadily enough and at the proper average speed to produce cost-effective electricity. I‘ve been a proponent of wind power since before it was popular, but it isn‘t the panacea the true believers preach about. At best, we will never produce more than about 20% of our total power needs with the wind -- and that much only if the technology continues to improve.
The same is true of tidal hydro. Technology will make it more useful, but it will never produce more than a fraction of our total needs. Transmission losses alone make it useful only within reasonable distance of a coast.
We will need and are working toward a combination of techniques for our future energy needs. What the whole process needs is fewer shouting true believers and more cooperation.
Here in Fort Collins we are building a CNG fueling station for our bus fleet. That plant will include a hydrogen generator. It will produce hydrogen from natural gas, which, as pointed out above, still leaves us tied to fossil fuels, although we have a good supply of natural gas and have the means to produce more, using various methane-producing processes. Still, the long-term solution will be for a low-cost method of producing hydrogen.
There is much talk of fuel cells, but the initial use of hydrogen will be in existing internal combustion engines. IC technology has advanced light years from the old carburator systems. All the pieces are in place to properly mix the fuel and control hydrogen-fueled engines. The big thing needed isn‘t fuel -- it‘s a distrubution system. Either the fuel has to be generated at many locations and piped to ‘gas‘ stations or it has to be produced at a few large locations and delivered to fuel sites much as gasoline is now.
I leave it to you to figure out which way Big Oil would like to have it work.
