Improve solar power generation technology

One point I made was that improvements in solar based power generation technology will reduce the cost of solar generated power to definitely lower than (as a rough guess about half the price of) coal in less than ten/10 years.

As the marginal cost advantage of solar over coal (or carbon generally) generated power increases, the "problem" of whether and how solar generated power will replace (in whole and in part) coal (or other carbon) generated power will be driven by business necessity and profit (the market).

In the meantime, any attempts to "manipulate" the market by subsidies, sanctions by government, PR campaigns (about global warming for example), etc. are probably not only "much ado about nothing" but often counter productive.

Patience is a virtue and reality rules - despite the most earnest ideological desires.

Government based programs which try to artificially stimulate (or warp) the free market inevitably lead to failure (often achieving exactly the opposite to the originally stated purposes).

At the margins, once the solar technology has matured, power generation will (can) be much more decentralized (even down to the individual home level).

Those micro (home based) technologies will take longer to be widely accepted and integrated into the larger scale energy production operations that will make the most economic sense (initially at least).
