Decentralisation of the electrical grid - only a matter of time
USA Today, August 26, 2007
Solar power has long been the Mercedes-Benz of the renewable energy industry: sleek, quiet, low-maintenance.
Yet like a Mercedes, solar energy is universally adored but prohibitively expensive for most people. A 4-kilowatt solar photovoltaic system costs about $34,000 without government rebates or tax breaks.
As a result, solar power accounts for well under 1% of U.S. electricity generation. Other alternative energy sources, such as wind, biomass and geothermal, are far more widely deployed.
The outlook for solar, though, is getting much brighter. A few dozen companies say advances in technology will let them halve the price of solar-panel installations in as little as three years. By 2014, solar-system prices will be competitive with conventional electricity when energy savings are figured in, Deutsche Bank (DB) says. And that's without government incentives.
