The environmentalists would say that these are all "dirty" fuels. Well, how "dirty" would it be if one or more of these Islamic oil exporters starts launching Nukes? I think I'll take my chances with the Greenhouse effect.
I think the environmentalists for the first time ever are starting to "warm up" to the reality that very few on the planet are going to just put on their Berkshire earth shoes and walk or ride bicycles and grow bean sprouts in their own self-made organic condo sand boxes. Times are a changin' and its about time.
Ultra safe Nuclear design has come a huge way over the years. Old design concepts that the US developed decades ago are being "stolen" and planned for by China and other countries. Nuclear is clearly the way the globe is going and I think the US will finally wake up to that reality soon. Apart from fuel/energy issues we WILL have electrical power shortages in this country soon if we do not greatly being to increase energy infrastructure of any type and FAST. No one seems to get it - the world is growing and expanding geometrically and conservation and minor 2-5% changes in efficiency are not going to cut it anymore. The growth curve (highly correlated with population birth rates) is very steep and can not be slowed without a large natural calamity or through traditional man man means of war. In essence humanity is a victim of its own ability to limit war and maintain relative global peace for a few decades. Wait till Africa starts coming on line like BRIC countries are doing with a real industrial revolution of its own in 30-40 years and then see where the planet is going next ...
Being an advocate of a healthy environment I am ALL FOR HIGH OIL PRICES. Sustained high costs of oil are exactly what the world needs to FORCE us/it to get off of it once and for all. Oil's time in the sun has come and needs to go fast. Its a transition energy and we now MUST get to something different. But it will take time to transition. The globe now needs a energy transition period and oil will have to be leveraged more effectively as a transitioning source of energy. More in a moment about that.
To a lessor degree we can also use a mix of wind, solar, bio, synfuels and coal gasification.
It's clear to me also that we have squeezed out about all the efficiency we can expect to get out of conventional gasoline car engines. The basic internal combustion engine thermodynamic cycle we use is all played out and at the "knee of the curve" for marginal gains in efficiency. Very very little unburnt fuel escapes out the exhaust now (at max .5-1% in a poorly tuned engine). But hybrid is a con game and will NEVER be cost effective since by definition its using less than optimum technology for both motive alternatives. It can't scale and compounds the technical problems.
However the much much superior thermodynamic efficiency of the diesel cycle will guarantee that diesel becomes the new bridge technology for the common man for the next 20-30 years. Let's face it - if we wanted to get an immediate 30% reduction in transportation costs everyone would just go out and buy a conventional gasoline motorcycle. But the truth is we are too domesticated and 95% of us will not take make that social/lifestyle change. Voluntary change only happens when it is convenient to do so or when there are no alternatives.
Diesel, with all the stunning new improvements in emissions control and amazing new auto performance (new power and high acceleration profiles, low maintenance etc.) is rapidly taking the world by storm. This is a mega trend that I suspect only about 1% of the planet is even tuned into. Watch Mercedes and other European auto manufactures take the world by storm. In 3 years I think most Americans will be dumbfounded to wake up to see that diesel has become the standard offering in all major car manufacturers. Those auto manufacturer's that do not go down this diesel path will be out of business by then if they have no offerings. Diesel will be the new swing/transition technology to get us to the next 20-30 years.
After that I suspect that personal transportation will be considered a luxury and society will migrate toward mass transit systems. The only way personal transportation will be possible in the future is if a radical new non-carbon based technology is developed (ultra high efficiency electrical with fuel cells, efficient battery or central electrical grid directly driven). But I think energy distribution must go to a large economy of scale networked utility grid concept using a mix of nuclear, coal, gas etc. feeding metered electrical transportation networks. Small scale personal auto power generation will never be able to compete with the economy of scale of large regional power and economics will drive it all to this model. Expect social change and profit by the trend.
But to tie it into the OP topic it all becomes mute if we do not put an end to the lunacy in the middle east or they continue to act as children and all refuse to grown up and insist on pushing humanity back 1000 years.
