My analysis of things to come
FYI, the tar sands have as much oil as Saudi Arabia, however the environmental cost is huge
That's an understatement... Stripmining sand, floating it in water and then treating it with natural gas or heat from nuclear power plants is not what I'd call a solution. The return on energy is barely 3:2, meaning you donk down 2 barrel equivalent of energy to get back 3... That's abysmal, might as well go fill up tankers on Titan!
Personnally, I'm not against nuclear power, I think it has the potential to be a true stop-gap measure between now and whenever we get to a full suite of alternatives, including solar, wind, tidal and fusion, in that order of availability.
If any good comes out of $150+ oil is that SUVs and pickups are getting sacked... Train freight is making a huge comeback nowadays in my part of the country and I envision that the airline industry will get a HUGE helping hand in developping an alternative to Jet-A... I watched an airline rep on CNBC today talking about the need to replace oil-based fuel with anything, as long as it won't require all new airplanes and engines.
Considering that a plane can easily stay in service in upwards of 25 years, as long as pilots don't ram them down to the ground too hard and too often, and the huge investment in time and energy in producing one single plane, I guess this sector is the one which will drive the requirements the most. With limited tank volume and fuel mass, we might even see a reduction in range as acceptable both to us and airlines, with a return of refuelling stop-overs on long haul and transatlantic flights.
Ships are pretty much lucky as they can deal with a wider range of stuff to drive marine diesel engines. Both for airplanes and ships I guess algae-based biodiesel will be the way to go.
Trains are fortunate enough to already be operating with electrical engines and not being really limited in volume (just add tank cars behind the engine), so I guess in North America we'll see a switch to hydrogen, with possible partial electrification of the railways.
Cars will pretty much have to reinvent themselves in a short-range role, as I don't think energy is going to be so easily and cheaply available in the near future. Trucks will pretty much be limited only to short hauls between customers and train stations, airports or cargo container terminals.
That's of course if and only if we get to a soft landing as far as transition goes. If agricultural output plummets as a result of price or availability of fuel or chemicals, we're screwed.
For now, I'm not that worried... My tipping points are either when
a) gas gets rationed
b) travel gets restricted
c) "staple" foods from abroad get difficult to obtain
d) pro sport events get cancelled
Any of these will be a sign we're getting in deep...
Those wondering about the relevance of pro sports in my list, just think about the implications causing this: high travel costs and/or low available allocations to leisure by the population
