Read the following text about last year's oil spill in the Gulf of Mexico.
The Deepwater Horizon oil spill is making Americans think more about a clean energy future – but not yet to the extent of having to pay for it, or to tackle climate change, one of the leading US thinkers on global warming policy said yesterday.
US citizens are "horrified" by the pollution in the Gulf of Mexico, and are starting to think more about cleaner energy sources such as wind and wave power, said Eileen Clausen, president of America's foremost climate think-tank, the Washington-based Pew Center on Global Climate Change.
However, she said, when consumers are asked by pollsters if they would be willing to pay more for such a future, they say no, and say the government should pay. Furthermore, Ms Clausen said, the Gulf disaster was giving US energy policy "a nudge rather than a shift" in the direction of clean energy, but it would probably not be enough to bring forward legislation to curb carbon emissions, at least for the present.
