Public Service Commission comment on Energy with an article on a possible breakthrough in Solar |
WHAT: The PSC will allow brief public comments (approximately 5 minutes per person) on Georgia Power's plan to meet future energy needs WHEN: Friday, May 11 at 9:45am and Tuesday, May 15 at 10:45am WHERE: 244 Washington St., S.W. Atlanta, GA 30334 (near the State Capitol) Or you may write or call the Georgia Public Service Commissioners: Bobby Baker, Chairman Chuck Eaton Doug Everett Angela Speir Stan Wise Reference Docket 24505 244 Washington St. S.W. back to index Atlanta, GA 30334 Call (404) 656-4501 or (800) 282-5813 Fax (404) 656-2341 public comment by Tom Ferguson In terms of energy strategies for Georgia’s future the same old same old is going to produce the same old results - pollution, negative health impacts for humans & animals, depleted resources and continued devastating global climate change. There are alternatives and they should receive a commitment commensurate with the ills they promise to alleviate: conservation, solar, wind and the potential of hydrogen. Conservation: a very large percentage of energy subsidies have gone to nuclear technology. This was, and is, a grievous mistake. That no insurance company will cover the industry ought to give us very serious pause. The long-term storage of waste and the vulnerability of nuclear sites, especially cooling ponds, to terrorist attack is far too serious to allow that industry to seduce us. But, the same level of commitment enjoyed by nuclear plants in the past can be applied to increasing efficiency and reducing consumption. Our state needs energy but we need a thorough re-examination of how we get it, how we use it and we mustn’t shy away from questioning whether the role of profit-making is necessarily appropriate. Wind: off-shore wind generation should be vigorously examined as an important potential energy source. The United States is way behind in the development and use of this “clean” technology. Solar: I include below an article on a claimed break-through in solar technology that, if accurate, is a far more exciting and promising direction than even wind. Monday view: Cheap solar power poised to undercut oil and gas by half By Ambrose Evans-Pritchard Last Updated: 11:31pm GMT 18/02/2007 Within five years, solar power will be cheap enough to compete with carbon-generated electricity, even in Britain, Scandinavia or upper Siberia. In a decade, the cost may have fallen so dramatically that solar cells could undercut oil, gas, coal and nuclear power by up to half. Technology is leaping ahead of a stale political debate about fossil fuels. Anil Sethi, the chief executive of the Swiss start-up company Flisom, says he looks forward to the day - not so far off - when entire cities in America and Europe generate their heating, lighting and air-conditioning needs from solar films on buildings with enough left over to feed a surplus back into the grid. The secret? Mr Sethi lovingly cradles a piece of dark polymer foil, as thin a sheet of paper. It is 200 times lighter than the normal glass-based solar materials, which require expensive substrates and roof support. Indeed, it is so light it can be stuck to the sides of buildings. advertisement Rather than being manufactured laboriously piece by piece, it can be mass-produced in cheap rolls like packaging - in any colour. The "tipping point" will arrive when the capital cost of solar power falls below $1 (51p) per watt, roughly the cost of carbon power. We are not there yet. The best options today vary from $3 to $4 per watt - down from $100 in the late 1970s. Mr Sethi believes his product will cut the cost to 80 cents per watt within five years, and 50 cents in a decade. It is based on a CIGS (CuInGaSe2) semiconductor compound that absorbs light by freeing electrons. This is then embedded on the polymer base. It will be ready commercially in late 2009. "It'll even work on a cold, grey, cloudy day in England, which still produces 25pc to 30pc of the optimal light level. That is enough, if you cover half the roof," he said. "We don't need subsidies, we just need governments to get out of the way and do no harm. They've spent $170bn subsidising nuclear power over the last thirty years," he said. His ultra-light technology, based on a copper indium compound, can power mobile phones and laptop computers with a sliver of foil. "You won't have to get down on your knees ever again to hunt for plug socket," he said Michael Rogol, a solar expert at Credit Lyonnais, expects the solar industry to grow from $7bn in 2004 to nearer $40bn by 2010, with operating earnings of $3bn. The sector is poised to outstrip wind power. It is a remarkable boom for a technology long dismissed by experts as hopelessly unviable. Mr Rogol said he was struck by the way solar use had increased dramatically in Japan and above all Germany, where Berlin's green energy law passed in 2004 forces the grid to buy surplus electricity from households at a fat premium. (In Britain, utilities may refuse to buy the surplus. They typically pay half the customer price of electricity.) The change in Germany's law catapulted the share price of the German flagship company SolarWorld from €1.38 (67p) in February 2004 to over €60 by early 2006. The tipping point in Germany and Japan came once households twigged that they could undercut their unloved utilities. Credit Lyonnais believes the rest of the world will soon join the stampede. Mike Splinter, chief executive of the US semiconductor group Applied Materials, told me his company is two years away from a solar product that reaches the magic level of $1 a watt. Cell conversion efficiency and economies of scale are galloping ahead so fast that the cost will be down to 70 US cents by 2010, with a target of 30 or 40 cents in a decade. "We think solar power can provide 20pc of all the incremental energy needed worldwide by 2040," he said. "This is a very powerful technology and we're seeing dramatic improvements all the time. It can be used across the entire range from small houses to big buildings and power plants," he said. "The beauty of this is that you can use it in rural areas of India without having to lay down power lines or truck in fuel." Villages across Asia and Africa that have never seen electricity may soon leapfrog directly into the solar age, replicating the jump to mobile phones seen in countries that never had a network of fixed lines. As a by-product, India's rural poor will stop blanketing the subcontinent with soot from tens of millions of open stoves. Applied Materials is betting on both of the two rival solar technologies: thin film panels best used where there is plenty of room and the traditional crystalline (c-Si) wafer-based cells, which are not as cheap but produce a higher yield - better for tight spaces. Needless to say, electricity utilities are watching the solar revolution with horror. Companies in Japan and Germany have already seen an erosion of profits because of an effect known "peak shaving". In essence, the peak wattage of solar cells overlaps with hours of peak demand and peak prices for electricity in the middle of the day, crunching margins. As for the oil companies, they are still treating solar power as a fringe curiosity. "There is no silver bullet," said Jeroen Van der Veer, Shell's chief executive. "We have invested a bit in all forms of renewable energy ourselves and maybe we'll find a winner one day. But the reality is that in twenty years time we'll still be using more oil than now," he said. Might he be wrong? back |
