Funny how the web site brags about donating a % of sales to the wounded warrior fund.
I've been thinking about a bumper sticker to the tune of
"No U.S. Soldier died to propel my car"
Anyone here make bumper stickers or seen any EV sticker that's similar to this?

If that is so, then why did they have to suspend the EPA regulations in order for fracking to take off? It seems as if those people who sell us oil may still want to kill us!camasleaf said:In 7 years we will not be able to say that driving ICE is giving money to the people that want to kill us:
Not that I expect it to happen anytime soon, but if electric cars caught on the reduced number of ICE cars needing oil as fuel might allow domestic oil production to be enough for self-sufficiency. One of the things I point out to those who are opposed to EVs is that they should be rooting for MORE EVs on the streets so that more oil is left for them to use in their ICE cars. I think the rational ones "get" it.RegGuheert said:...In any case, don't hold your breath. I do not expect the U.S. to ever again be self-sufficient for oil.
DaveinOlyWA said:I keep reading reports (actually only the first paragraph or two) of massive new finds of oil in the US, Australia, etc that will "supply the world for decades"
am I to believe they are lying (i do) or exaggerating? (i do) Or should I best believe that the environmental impact would be too severe? (not that oil companies would care about something so trivial)
Here is a recent article predicting the worldwide peak in coal production to be around 2050. It is a very long article and it discusses some other predictions that are out there.WetEV said:There is a lot of coal known about now, hundreds of years worth even with a growing rate of consumption.
Agreed. Unfortunately, the penalty for burning coal (or oil, for that matter) lags by so long that we are likely to burn more than we should. Perhaps we have already passed that point.WetEV said:And to be blunt, we have no realistic chance to burn it all due to greenhouse gas concerns.

I saw it past $4.05/gal 3 days ago over here. Even many cheap gas stations are past $3.90/gal now. http://www.sanjosegasprices.com/" onclick="window.open(this.href);return false; pegs our avg at $4.033/gal now.DNAinaGoodWay said:Gas dipped to as low as $3.29 here this winter, but lately has crept back up to $3.69.
Sure, but England is land. Most of the world is covered in oceans, so the rate for recovery of coal worldwide should be lower than for England.WetEV said:I'm not very convinced that only 5% of the coal is minable. I don't think so. UK, for example, has mined about 27 Gt to date, and total resource estimates range from (from memory, I can't find a reference quickly) 80 GT to 160 GT. And the UK didn't mostly stop mining coal because the seams ran out...
That is a common misconception regarding the extraction of energy resources. It has nothing to do with the price. It has to to with Energy Return On Energy Invested (EROEI). Simply put, if it takes more energy to extract the coal than the energy content of the coal itself, you cannot recover the coal because you would be a net energy consumer instead of a producer. (You might extract the coal for some other purpose besides energy, however, if it is somehow valuable for other purposes.)WetEV said:How much is minable? Of course it will depend on the price vs the cost of extraction. The higher the price, the more that can be extracted.
The big problem is to distinguish between reserves, which are expected to be produced economically with the known technology and resources, in essence the volume without any constraints. Presently, coal seams less than 50 cm thick, deeper than 1500 m or offshore are not considered as reserves. This is why for the world the volume of resources is more than 20 times the volume of reserves. The constraints are mainly energetic: energy return over energy invested.

I agree. My sense of the research is that even if we stopped burning fossil fuels today the higher levels of carbon dioxide in the atmosphere will continue climate change for decades to come. Add to that the tipping point where large amounts of methane stored in the oceans or in frozen ground is released by the warming climate and the change could accelerate regardless of additions to CO2 levels.DaveinOlyWA said:you nailed it Ray

GRA said:$4.06 yesterday at my corner gas station. Maybe $4.00 if I looked for the best prices. anyone know what's been driving the big runup (ca. $.50/gal.) in the past month? I heard about a couple of refinery shutdowns, but IIRChey were out of state so don't think that would affect California. And crude prices have gone up some, but nowhere near enough to cause that big a boost.
