Not all solar power plants totally 'green'

Las Vegas-- Not all solar thermal power plants, touted for their environmental benefits, are pollution-free because they also use other fuels, U.S. experts note.

Solar thermal plants are expected to sprout up across the sunny U.S. Southwest as the nation looks for so-called green energy alternatives. But the Las Vegas Sun reported Monday some of the solar plants are designed to use natural gas or propane boilers to jump-start the units each day, releasing greenhouse gases.

While the solar plants would produce only a small fraction of the carbon monoxide, nitrogen oxide and particulates natural gas-fired power plants produce, the amounts would add up for a region in which no fossil-fuel plants are planned, the Sun said.
