If conservatives would realize that the short-term costs are outweighed by the long-term benefits of environmentally friendly products. Why would you not want a bulb that lasts longer and uses a fraction of the energy of another bulb. Why would you not want your SUV or Truck to get 25+ mpg. Though there are short term investments that must be made, the benefits in the long term can be astounding. Why should we pay more and more in electrical costs to utility company's when everyone could theoretically generate their own energy needs. I guess conservatives would rather spend more on obsolete technology to maintain their view of Ammurrica.
People can't generate their own power needs lol. Centralized power generation is more efficient. The bigger the generator the more efficient usually. The engines in boats/cruise liners/tankers for example actually convert a higher percentage of the energy in fuel to kinetic energy versus heat.

I'm taking Pchem right now *bangs head on wall*
But basically all the little 4banger 1.6L engines actually do a terrible job of converting the energy in oil to kinetic energy, they just have long gears and less weight to carry around IE a honda Fit.
Their actual efficiency is however, very very terrible.
In terms of power generation there is no way something at home can get the efficiency of a steam turbine powered by coal.
If you are talking about solar panels etc, not only is there the upfront cost but alot of the waste is externalized upstream in manufacturing. So for us its a green technology but not so much for wherever we dump the waste we used to produce them.

Solar panels won't pay themselves off until 2020 but who knows if that will hold true if any of them are damaged or need repair.
So solar is *barely* pulling its own weight. If you place the panels out in the desert, yeah they will pay themselves off. If people were putting them on their roofs like you propose people could do for their own energy needs, then no they wouldn't pay themselves off and would be a net energy drain.

This kind of highlights the effect. Pushing the Prius hard drops its mpg to 17.2mpg and the BMW simply had to keep pace, and got 19.4mpg. I'm not really surprised because bigger engines are more efficient. The Prius just has long gears and drives slower, and in traffic recaptures some of the energy from braking.
Just kind of an FYI I guess that there is no magic bullet to energy problems like the eco-kooks believe.
