I'm afraid that is untrue. The science behind the trend towards global warming as a result of increased CO2 in the atmosphere is virtually undisputed, despite the same outdated study that Rush Limbaugh quotes time after time.
There is very little financial gain to be made by saving energy, and billions to continually be made by using fossil fuels in excess. It is baffling to me that solar panels were being installed on homes all over California in the 70s. Since then, technology has changed to an almost unrecognizable state, yet, solar sources are still under-studied and under-produced. You can't sell sunlight, so no one is interested in it. You can't sell wind, so no one is interested in windpower. Oil? Petroleum? Now there are some money-makers.
Regardless of whether you accept that the warming trend is spiking (we're talking centuries here, not year by year), there is no denying that fossil fuels are a finite resource, so either way, conservation of energy, along with improving sources of renewable energy, is the sensible way to go.
