Cheap solar power poised to undercut oil
and gas by half
Within five years, solar power will be cheap enough to compete with carbon-generated electricity. 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. 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? A piece of dark polymer foil, as thin as a sheet of paper. It is so light it can be stuck to the sides of buildings. 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. 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. “We don’t need subsidies, we just need governments to get out of the way and do no harm,” he said. Solar use [has] 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. The tipping point in Germany and Japan came once households [understood] that they could undercut their unloved utilities. Credit Lyonnais believes the rest of the world will soon join the stampede. Needless to say, electricity utilities are watching the solar revolution with horror.
