Good points, Larry. You sound like a guy with a website.

Presumably you are only talking about power generation for the grid. As mentioned in some of the posts above, distributed generation and cogeneration are increasing efficient use of fuels while reducing loads on the grid itself. These are methods of utililizing existing fuels more efficiently.

Windpower is a comer, but it suffers (as you are well aware) from variability by source, not load. If your power needs to not coincide with wind levels, you need something else to bring up the balance. That is why wind is always thought of as a partial, or fill source. There's a techncial term which I forget. Also wind has great environmental repercussions, over the land on which it is installed, on bird routes, and, as you start converting more and more of the available power to electricity, you are going to affect the weather, locally or globally depending on whether chaos effects come into play. (Yes, we're probably a few years ahead of ourselves, here).

Railroad trains are already the most efficient way to move materials on land. They have been modified in Europe and to an extent are still being modified in the US to run off the grid, except for the long distances out west.

We are still going to have to solve the issue of increasing cost for transportatioin fuels for cars and trucks. Manufacturing hydrogen at plants in off-peak hours is one way to pursue.
