We can only hope that in addition to political support, that funding is adequate to make it a reality. As the article mentions, this will require not only will power, but also lots of money and workers. So overall, 20 percent of energy production from renewables may be a lofty goal.

In support of the idea, if what I am reading is accurate, small solar PV systems costs should drop significantly in 2009 (lower module costs), and may even reach so-called ‘grid parity’, i.e. cost the same per kWH as utility power.

Also, in support of small solar are increased federal tax rebates of a full 30% on residential solar systems should be an incentive for homeowners (if we have any money!).

On the other hand, utility-grade solar is hugely expensive and so depends on lots of capital and time to build out. What is emerging as the ‘gotcha’ with utility-grade solar is how to get the generated power from the source (i.e. middle of nowhere) to big cities.

But perhaps the biggest holdup for solar is the need for a major power grid overhaul to handle the 1000’s (millions?) of home grown and utility-sized systems.

Right now, wind and geothermal are niche players.

Wind is highly geographically concentrated and very expensive. Geothermal seems to need some technology breakthrough, and is also very costly.

ANY one of these clean energy sources can satisfy a major portion of our country’s energy needs, given enough time and money.

To ombine renewables with better gas mileage, plus switching over to CFL lights, plus other energy saving measures, plus recycling, then we will really leverage our goal of energy independence.

So let’s get with it!
