When your local utility buys more renewable energy to power your lights and computers, what more do you get besides the power?
You get cleaner air, fewer respiratory health problems, and lower health-care costs.
You get local jobs building and maintaining green power plants and a better foothold in the fast-growing, multi-billion dollar global renewable energy industry.
If you use the power to charge the new plug-in electric vehicles now available, you reduce our imports of foreign oil and increase our energy security.
And finally, you reduce the greenhouse gases that are leading to the severe, threatening weather events spurred by global climate change.
These are all fine benefits to economics and clean air, but it is rather egocentric to believe we can stop the warming and cooling cycles of the Earth.
My point of contention is that reducing greenhouse gasses sounds like a good effort, but barely makes a dent in the natural process. Over 99% of those gasses is water vapor. There is little to nothing we do which will effect the hydrologic cycle, other than pollute water to a point we can no longer drink it.
Reducing greenhouse gasses promotes cleaner air in the lower atmosphere, a much greater benefit than to attack "global warming." the Earth goes through natural cycles of warming and cooling on a scale greater than we can imagine, with even less chance of our actions effecting those natural cycles.
Natural selection rewards those species which adapt to changing environments.
