Thanks for that input Solarman. But I think you didn't answer my question. Hmmm.
Anyways, Thanks for the response.
Perhaps you've asked the wrong question. You need to ask yourself, WHY you pick three institutionalized energy sources and look for the "best" one. This thinking leaves YOU out of the equation. The technology of wind and solar, both PV and hot water are at levels that the average Joe can afford to install and use. It is now that YOU can take responsibility for the energy you use daily. Folks are saying that natural gas is the "best" option. What is unknown is at what long term cost to the environment due to fracking. It seems there could well be adverse effects to the potable water supply, there could also be some adverse effects with destabalization of substrates and increased seismic activity in areas of rock formations "fracked" to get the natural gas. Before you ask what's "best" look to History for an answer. DDT was the wonder pesticide of the modern era. It could prevent vectors such as mosquitos from spreading diseases such as malaria and increased crop yields. Finally found out, it is also environmentally invasive. Before you pundit such questions, think "Silent Spring".
