Even the most ardent supporters of biofuels aren't claiming this. To
wean ourselves off petroleum, we need a mix of energy sources, and yes,
changes in behaviour.

Nice in theory but you also need population density and reasonable
distances to make many of these things work. Many parts of Europe have
that so these things will (and do) work there. That doesn't always work
too well in places that have low populations and vast distances, like
Canada for example. To put things into perspective, Canada is the second
largest country in the world, after Russia, and has a surface area of
almost 10 million square km with a population of about 33 million for a
population density of 3.3 people/sq. km. The most densely populated EU
country is Malta with 1274 people/sq. km and the least densely populated
one is Finland with 16 people/sq. km. While averages can be quite
deceiving and not necessarily relevant, they are a data point. You would
never know that Canada is so sparsely populated if you were on the Queen
Elizabeth Way heading into or out of Toronto. It is the second busiest
freeway in North America after the Santa Monica Freeway in Los Angeles.
Most of Canada's population lives within 100 km of the U.S. border with
38.5% of it concentrated in Southern Ontario alone. In my immediate
area, we have good opportunities (that are squandered) for better public
transit but that is not the case for many areas of this vast country.
Inviting another 400 million or so of our best friends to come live with
us does not seem like a likely solution to the problem either.

I have read such allegations and in the short term, I can see it
happening but in the long term, such attempts to manipulate prices will
fail. Not even nations have enough money to corner the market on oil
futures so anyone foolish enough to try will meet the same fate as those
who tried to corner other markets, like the Bass brothers who lost
billions when they failed to corner the silver futures market in the
1980s

All true but you have to start somewhere. Early gasoline-powered cars
were not particularly reliable either. These alternative technologies
will improve over time and not necessarily in a linear or predictable
fashion. This does not even take into account the "next big thing" that
is still a gleam in someone's eye today. Perhaps the problem with all
the alternatives is that they don't change the paradigm. To take an
extreme example, if quantum teleportation were not the stuff of science
fiction, why would we need cars? I'm not suggesting that cars will (or
will not) be replaced by quantum teleportation. I'm suggesting that
something equally incredible could change the course of history. We just
don't know what that is yet.

I'd never heard of jatropha <http://en.wikipedia.org/wiki/Jatropha>
before. It sounds interesting and it probably could grow here but I
wouldn't be surprised if it would be considered an invasive species.

Perhaps we should just wipe out the human race to eliminate this deadly
"climate change" gas we produce too. We'd have a perfect "Mother Earth"
then.

If the "climate change" cult is right, Ontario will become a very
temperate place to live all year round so I say "Bring on the climate
change!" :) I recall many scientists being on a "The next Ice Age is
coming!" bandwagon in the mid '70s. What happened to them, I wonder?
