According to this CNN article released today Concentrated Solar Power (CSP) that harnesses the heat of the sun (not the brightness of the sun, which is what Solar PV does) just keeps looking better. Among the claims:
1) Electricity produced by CSP can be as cheap as 8 cents per kWh. That’s about 20% cheaper than most people are paying in the united states right now for electricity. That’s1/4 the cost of electricity produced by the ever so much more popular Solar PV panels.
2) A 92 x 92 square mile CSP farm placed in the empty barren desert in the SW United States could produce all the energy needed by the whole United States.
3) It could easily solve the desalinated water shortage crisis – which for many countries is a much bigger problem than any kind of oil shortage crisis.
4) Only 0.3% of the Sahara desert is needed to power most of Europe and upper Africa, resulting in a 70% carbon reduction for the region. It will save astonishing amounts of money too as cities must otherwise relocate costing of 100’s billions of dollars, whereas it could all be averted with a CSP plant in the $10 billions of dollar range.
5) Since 90% of the world lives relatively close to desert or to substantial power grids connected to such areas then 90% of the world’s population can be served by this breathtakingly economical and clear resource.
Strangely enough some of the biggest opponents to CSP appear to be a group of environmentalists and key Democrat politicians who seem to be letting expected tax incentives lapse. Based on my last post, you’ll see that this comes as no surprise to me. For 30 years they’ve been trying to keep CSP in the background so industry experts could make money off new alternative energy startups that will never compare with respect to efficiency, cost, and time to market.
These tax incentives for the power companies are vital. Even though CSP may be cheaper than filthy fossil fuels, power companies are making tons of money on fossil fuels. They have the right to jack the prices as high as they need, and at times like now when there is no shortage, but the cost is high due to political concerns, they make all the money. Why? Because they already own such a huge interest in the reserves. The only way to get power companies to build CSP farms is to financially encourage them – and that isn’t happening.
