“The short version is that a wedge represents a climate solution that starts slowly but then rises in impact over the 50 years and ultimately avoids the emission of one billion tons of carbon per year. If the average car on the road in 2057 got 60 miles per gallon, that would be one wedge.
The world needs 8 to 10 wedges, starting now, to avoid catastrophic global warming. Interestingly, the report makes clear that:
For nuclear power to be even one wedge we would need 10 Yucca Mountains to store the waste.
We would have all of the proliferation risks associated with spreading nuclear power across the planet.
And the power isn’t cheap: 8.3 to 11.1 cents per kilo-watt hour.”

This article doesn’t even factor in the resources needed to cool nuke plants.
Maybe superconductor tech, cold fusion or some other break thru will change the scene– if they can be researched and implemented in time, but the bald facts are these:
The so called clean coal we have now puts out more carbon than oil does.
Biofuel as it is now, will further tax poor soil quality and will mean less food for the planet, also ” the U.N. warns, that could lead to erosion, nutrient leaching,and — if the crops replace forests — ‘large releases of carbon from the soil and forest biomass that negate any benefits of biofuels for decades.’ ”
‘Tho Gore makes an argument for a biofuels as a transitional energy source. Read here about that.
Solar will be getting cheaper & better, but even combining it with hydro, wind and fuel cells (none of which are in place on any scale & it will take oil to manufacture the change over to them, btw.)
Throw in nukes– sure why not, even tho we still don’t have a good solution for the waste, if you want, or investing more in getting to what oil is left in tar sands or in the Antarctic.
None of it will keep up with our current energy use.
I say use and not needs, because I’m deeply convinced that we need more community and less strip malls. More intimacy and less mass media entertainment. The ever amazing Colin Beavan has a great post on the topic right here .
We will have to scale down & localize much more than we are used to. We don’t have much more of the single cheap energy source we have. None of the replacement tech currently offered is going to be *nearly * as plentiful & inexpensive as oil and we don’t have the infrastructure for replacing oil yet. Global climate change is going to make transitioning to other options even more expensive than it normally would be as supply lines and whole economies become destabalized.
So maybe we’d best take this as our wake up call to re examine our values. Maybe , even if we could buy as many McMansions, SUVS and home theaters as we wanted, they simply woulden’t feed us what we truly need: which is, in my opinion, a sense that we are a human family together, exploring and learning in a universe full of wonders.
