Wind and solar offer little hope for widespread use.
Don't give up so fast. Take your average suburban house, make sure one side of the roof is slanted, free of obstruction, and facing south. Cover it end to end with solar panels rather than shingles. The house will then be supplying more energy to the grid than it needs to take from the grid during the off-hours (ie: night, cloudy). Solar panels are absolutely ready for widespread use, the biggest obstacle being the initial cost.

Great ideas but lets be realistic. COST is a big factor in alternative energy. One energy expert on FOX the other day said if we are willing to pay the equivalent of $3.00 per gallon for gas indefinably we can pretty much have what we want. If that price is a problem then the government would have to subsidize the efforts with 100s of billions for years to come.
I see your point, but I do not think the complaint here is about the price of gas. Cost is an obstacle, but the object is energy independence.

One comment about “hydrogen” cars and fuel cells. Fuel cells use gasoline (to make hydrogen) and hydrogen production requires LOTS of electricity. To think that the production of same, without a massive increase in nuclear or other power alternatives, is clean is an illusion.
So true. It appears that most people don't realize that hydrogen fuel cells are only storing a source of power, not magically creating it. And unless we find a massive reserve of hydrogen that isn't being used in a nuclear reaction in a massive ball of plasma, we will have to produce it. Also, it will take more energy to produce a fuel cell than that cell could produce, unless we brake certain laws of physics.
But wait, we don't need to throw the technology out the window. Aside from the potential benefits of centralizing the energy production (from the car, as it is today, to a fuel cell plant) there is an interesting application of this technology with respect to energy independence. We could use energy from the Sun to separate the hydrogen from the oxygen of a water molecule. Then, we can take the resulting emissions (water vapor) and separate them again. However, I doubt that we could do this on a large scale.
