Sun (power) will rise tomorrow

Official sees solar energy ending U.S. dependence on oil

The internal combustion-engine and coal-fired power plants will become as outmoded as the horse and buggy -- if the country embraces available technology and harnesses the power of the sun.

That's the assessment of David Mills, a doctoral-degreed physicist and chairman of solar-energy developer Ausra.

  • Mills presented a scientific paper on the subject Wednesday at South Point during the 14th biennial CSP SolarPaces Symposium, a program of the International Energy Agency.

    "An almost complete elimination of both fossil-fueled generation and oil usage for transportation in the U.S.A. appears to be technically feasible," Mills said in the paper. "This paper presents solar electricity as the most likely means to nearly eliminate contributions to global warming from electricity generation by midcentury."

    Scientists believe that carbon dioxide from coal- and gas-fired power plants and gasoline-powered cars leads to global warming.

    Mills envisions the nation replacing coal- and gas-fired power plants with clean solar thermal plants that provide electricity for residential, commercial and industrial customers. Also, Mills said, plug-in electric cars could eliminate the need for gasoline-burning vehicles. Drivers could either recharge their batteries overnight or use quick-charge technology.

    Mills is chairman, founder and chief scientific officer of Ausra, the Palo Alto, Calif.-based company that is installing a solar thermal assembly plant in Las Vegas. The company also is developing a 177-megawatt solar thermal power plant in California for Pacific Gas & Electric.

    Bob Boehm, distinguished professor of engineering at the University of Nevada, Las Vegas and director of the Center for Energy Research, mostly agreed with Mills' conclusions, although he had reservations.

    Nevada and other Southwestern states have some of the world's best solar resources, Boehm said. He wasn't sure whether power from solar thermal was feasible in states like Washington and Maine, but Boehm suggested Northern states could use wind power.

    Thermal storage is the key to solar power's promise, Boehm said, because it will allow solar thermal power plants to store heat and continue to generate electricity after the sun sets. Mills' paper talks about thermal storage lasting 16 hours, making solar power virtually available around the clock.

    Boehm said he didn't have information on Ausra's research into thermal storage using water and couldn't predict whether Ausra would become a solar thermal leader.

    "But that's the direction things have to go," Boehm said.

    Critics often question renewable energy's cost. But Mills said solar thermal power is becoming competitively priced with coal-fired plants when solar plants are built in the 500 megawatt to 1 gigawatt size. A gigawatt is a billion watts.

    Mills studied electrical power-use patterns in California and Texas, concluding that solar power generation fits well with those states' daily and seasonal energy use patterns.

    For example, electrical demand typically peaks in the summer when solar thermal plants are efficient in generating electricity.

    Mills suggested that the country could convert cars and trucks to electric power and get the power from solar plants built over the next 30 years.

    "Then, the annual generation replacement cost would be between U.S. $24 billion and U.S. $52 billion," he said.

    For each year, however, the country would save $48 billion in imported oil, he said.

    With oil going for $100 a barrel, the payback for going solar would come in 18 months to three years, Mills said. (Light, sweet crude for April delivery fell 32 cents Friday to settle at $105.15 a barrel on the New York Mercantile Exchange.)

    Another benefit would be less pollution from fossil fuels such as gasoline, natural gas and coal, he said.

    Boehm said the United States led the world in renewable-energy technology several years ago. Now, the United States depends on Asian and European companies for most renewable technology.

    "The solar thermal industry is our last chance to be in the (renewable) market," Boehm said. "Otherwise, we're going to buying stuff from overseas."

    d'Oh! wrote on March 10, 2008 12:04 PM: constructive skepticism is good, but consider this: it would take less than 1% of the landmass of the world's deserts to produce the same amount of electricity via solar thermal produced worldwide from every source today. even with tax credits that are in place now, solar plants pay about 1.7 times more in taxes than fossil fuel plants. Give them a level playing field and turn them loose!

    Yes, they do. Please check their own web site.

    And while I'm at it, I'd like to add that the US imports most of it's plutonium from Russia and has for over a decade. Now, more and more of our urainium is from Russia as well. Would you have us trade one foreign master for another?

    Please critique the responses of the two guys kbeuchert and adpd. How are there assertions invalid? What do you have to add? Are you a democrat?


    2zero wrote on March 08, 2008 06:04 PM: It amazes me that these simpletons call "environmentalists" idiots. These are the same people who get in line to buy "clean coal"; a not so slick marketing propaganda jargon! Fact is that ten years ago Vegans could have installed solar on every new roof built. No land required, no power lines and paid for over the life of the home. Those coal fired power plants are financed for 40 years and that is reflected in your monthly NPC bill!

    GE builds power plants... GE builds turbines for hydro, geothermal, and fuel-fired plants, BUT GE DOESN'T BUILD NUCLEAR, NATURAL GAS, OR COAL-FIRED POWER PLANTS!

    Now, David Mills heart is in the right place, but his mind and economic sense is certainly not. Does he expect the land, transmission lines, and tons of subsidies to fall out of the sky?

    Oh, and let's quit blaming OUR problems on the middle east. We Americans are energy hogs. Just look at the 215 beltway to see one person driving a huge SUV; just look at the Vegas skyline at night; just look at jet after jet on final into McCarren --- need I say more?


    Ugly American wrote on March 08, 2008 09:42 AM: Pay attention. The UAE and Saudi Arabia are rushing to build solar power plants. Why do you suppose that is?

    Just the new coal plant at Eli was estimated to need $350M worth of coal a year. Since then, the cost of high grade coal has more than doubled from $50/ton to $100+. Why? US anthracite production peaked in the 1920s! That means you could build 3 new solar plants every year for the cost of the coal alone. Size? Have any of you seen the staggering dammage done by strip mines and mountain top removal or the permanent dammage to lakes, rivers and drinking water?

    Nuclear plants? The waste will be dangerous for thousands of years and it turns out we don't even know how much it will cost to secure it over the total lifecycle. On top of that, despite the promises of cheap power, nuke plants have cost billions just to refurbish and even when the federal government takes their waste and dumps it in Nevada for "free" it still costs more than wind power. The week before the Texas wind dip led to some factories being idle for a few hours, 6 nuclear reactors had to be scrammed in Florida leaving over half a million people without power. How reliable is that?

    It is a fact that both solar and wind cost less than coal or nuclear in the long run because there is no fuel cost, no waste disposal cost and no major safety hazard.

    But you might not hear that on the news because companies like GE, who make the coal and nuke plants also own the news channels. Go look it up.


    cj wrote on March 08, 2008 08:27 AM: as soon as solar power becomes economically feasible to put on my house, im all for it. i think most people would be as well. the problem is, at this point it costs WAY too much. i would never get my money back. by the time the PV system pays for itself, i would have moved out years previous to that. we need to find a way to produce residential PV systems at a lower price.
    also, like said by roman, we need to invest in nuclear. that is the way to go, since it is dependable and consistent.
    also, when we "plug in" our cars, that power now comes from coal fired plants, so we are really just shooting ourself in the foot.
    the problem is, this problem seems so large that government has to help, and im not sure how others feel, but the government is almost useless as far as doing anything productive. they just like to divide at the partisan line and blame each other, block each other, and complain at each other. while all that occurs, we the people end up getting hurt while the lifetime, old fart, paid off politicians do nothing for us.


    lgee wrote on March 08, 2008 08:21 AM: Go out and look at the solar array in the Eldorado valley. The HUGE amount of mirrors required to generate 63mw of electricity is staggering. Can you imagine how big the array will have to be to generate 1500mw? When the environmental left sees this they will object to these projects as well. Most wind power projects have environmental groups protesting their construction due to bird kills or the fact that they are being built near their home. The power has to come from somewhere, quit being so hypocritical! The answer is to develop all types of power generation including new clean fossil fuel plants. If we choose to concentrate on expiramental technology wait til you see your power bill of the future!
