Solar Energy Could Power U.S. Many Times Over
If the U.S. moved aggressively to start harnessing the solar power it receives daily, it could generate enough clean energy to meet the country’s needs many times over, according to a new report from Environment Florida.
The report, “On the Rise; Solar Thermal Power and the Fight Against Global Warming,” touts the multiple benefits of solar thermal power that the U.S. has barely begun to tap. One, it’s a clean source of energy that could replace other power sources that generate greenhouse gases and worsen climate change. Two, by storing thermal energy, it can generate electricity even when the sun isn’t shining. And ,three, it’s wildly abundant in the U.S., offering way more clean energy than we currently use on a daily basis.
The report notes that a 100-mile-by-100-mile solar thermal installation in the American Southwest could meet the entire country’s energy needs. That area, it further adds, is just a little larger than the amount of land in the U.S. that has been strip-mined for coal.
“If we are going to get serious about fighting global warming and addressing our energy challenges, solar energy must be part of the solution,” said Holly Binns, Environment Florida’s field director.
While the Southwest alone could generate more than 7,000 gigawatts of energy, other parts of the U.S. — including Florida — promise a large potential for solar energy development. The Sunshine State has some catching-up to do, but recently improved its clean-energy performance with the opening of the Sunshine Energy Solar Array near Sarasota. The 28,000-square-foot array, Florida’s largest to date, can generate 250 kilowatts of energy, enough to power about 45 typical homes per month.
Clearly, the state will need quite a few more like these to make a serious dent in its fossil-fuel consumption and carbon emissions. Florida officials hope recently approved green-energy legislation will encourage those kinds of developments. The bill includes, among other things, authorization for a cap-and-trade program to reduce greenhouse gas emissions, a renewable fuel standard and renewable portfolio standard that promotes wind and solar energy, and new building standards that call for higher energy efficiency in new homes and businesses.
At the national level, the Environment Florida report is also encouraging. With the right policies, it says, the U.S. could easily generate 80 gigawatts of concentrating solar power by 2030. That would be enough to power 25 million homes, reduce carbon emissions by 6.6 percent and create between 75,000 and 140,000 new jobs.
Good news — for a change — isn’t it? Let’s just hope the right people are listening.



Solar is more flexible than many of these commenters realize: the 100 by 100 sq mile area can also be usable for other things, even grazing if feasible if panels are mounted on trackers or elevated arrays, and it doesn’t have to be a contiguous area either.
Hey Fred, Solar doesn’t use waste ANY water for cooling (nuclear and coal), requires virtually NO maintenence and has NO EMISSIONS—-get it yet?
have heard about this for some time. what kind of price are we talikng about for a2000 sq. ft ouse?
Solar electric power isn’t green or environmentally harmless. The average reflectivity (albedo) of the land areas of the earth is 30%. The average reflectivity of solar panels is 5%. If you cover an area with solar panels you capture and retain 25% more solar heat than if you didn’t have those solar cells in place. Every kilowatt of solar electric power carries an extra heat load of about 7 to 9 kilowatts of captured heat energy. Of that 25% is heat that would have been bounced right back into space as reflected energy. This makes solar electric power one of the least green energy sources in terms of the direct impact on warming the planet. Note also that this effect is independent of greenhouse gasses and who or what is responsible for them.

Any large scale solar installation is going to have some negative effects on an area, but surely it’s a step in a…..better direction. Harnessing renewable energy opposed to being dependant on any type of fuel is key inn moving in the right direction.
