The most near-term, cost-effective solar solution is undoubtedly solar thermal. While photovoltaics, which convert light directly into electricity, can have a significantly smaller footprint and higher efficiency...solar thermal has generally proven that it can create electricity at a lower cost.
With that in mind, the U.S. Department of Energy has decided to spend $60 M over the next five years developing low-cost concentrating solar thermal technology (like the parabolic trough pictured from Schott Solar.) They plan on making between 10 and 20 awards to industry and universities working on increasing the efficiency and decreasing the costs of solar thermal power.
They will also be funding projects related to "advanced thermal storage." At first this might seem slightly unrelated. In fact, what they're looking for is a way to store the heat captured during the day so that they can continue to generate electricity throughout the night. This is another possible advantage to solar thermal technology. If the heat can be stored in some medium, say molten salt for example, then that medium could, in effect, make the solar plant a giant battery. Photovoltaic plants, on the other hand, would require some other form of backup energy to keep the juice flowing at night.

Putting corruption and politics aside, the government, by the best of intentions, is incapable of efficiently funding useful arts and sciences. It is the same reason that the Soviet Union collapsed economically: because there wasn’t an effective pricing system to put the scarce resources to the places of the most need. Only a free market can do that.
There is another mistake the people usually make. When we see the article above, and say “This country sucks because look how much this country does NOT fund solar thermal energy.” It is making the mistake of how much the government is funding this endeavor with how much other people in this country is funding it, or developing it, perhaps some of the readers here, without government funding. When someone uses his own money to develop these needed resources, he has an incentive to make the most out of it, and to see that it gets results. Tom Paine in his 1776 booklet “Common Sense” which sparked off the Revolutionary War made this distinction between government and its people, the rest of society. With noting this distinction, the USA became the most free, prosperous, and I dare say the most ecological country in the world.
