I don't think that the world is going to suddenly stop using fossil
fuels, particularly oil. I don't think I've read other people saying it
will stop suddenly.
It will take
time to find substitutes for oil in some applications. It seems likely
that it will be difficult to find substitutes for oil for ships and
aviation. However, the US Navy is planning on using 50% renewable energy
by 2020. It seems hard to imagine how they could do it that fast. But the
point is that they clearly think that they can make a major shift towards
using a lot
more renewable energy, and surprisingly fast. Aviation may well be a lot
more difficult. But difficult is not the same as impossible. Impossible
is forever, and forever is a long time, particularly with all the
innovation and discoveries coming out at a steady pace. For example, the
Toyota Mirai hydrogen fuel cell vehicle is being sold this year in
California. Transportation may use around 1/3 of the oil used, only a
portion of it being used for ships and aviation. But it is a substantial
amount of oil that may take a fair time to replace, and will likely be
replaced gradually. Even cars will not be replaced with electric vehicles
instantly, it will take time even if all goes well. It can be done, but it
will take time.
Oil is also used as a feedstock for the chemical industry, some of
their products are vital to the economy, I would think. I don't think it
is necessarily wise for us to burn what we need for feedstock. Also, the
feedstock industry will continue even if we stop burning oil.
On the other hand, coal is the dirtiest of fossil fuels and can be
replaced completely. That is already well underway with conversion of coal
fired electric plants to natural gas. Natural gas has the advantage of
producing much less non-CO2 air pollution and somewhat less CO2 pollution
than coal. It's climate impact will depend on whether methane leaks are
stopped or not. I seem to remember that Obama has a new proposal to reduce
some methane leaks. Leaks can be reduced to low levels.
Further, I don't think the advantages of scale will be reduced if we
go from 100% of current oil consumption to 90% or even to 30%. The highest
up-front costs for the oil industry have all been paid, for the
infrastructure, the wells, pipelines, refineries, ships, etc. Since a
portion of those can continue to be used, I don't think that the advantages
of scale will be lost anytime soon. Maybe by 2100, but it is hard to know
in advance what energy sources will be available by then.
We need to level the playing field between fossil fuels and renewable
energy, by removing the huge subsidies for fossil fuels (estimated at a
half Trillion US $ per year) for a start. Economist argue that subsidies
distort economies, making things that are actually not profitable,
profitable. In effect, it is taking money from all taxpayers and giving it
to individual companies to provide the profit that they can't produce on
their own. It makes the economy as a whole less efficient and competitive,
so the nation as a whole pays a price. Subsidies that pay for damaging the
environment have been called "perverse subsidies." No wonder renewable
energy can't compete, with subsidies like that. A carbon dividend can be
levied on carbon at its source and the revenue distributed to residents.
So revenue-neutral. Doesn't kill the economy. British Colombia, Canada,
has such a program, and it has been quite successful (
http://www.skepticalscience.com/co2-limits-economy.htm). European oil
companies want a carbon price, so they can plan ahead. Once these things
are done, suddenly renewable energy will become less expensive than fossil
fuels, and people will shift voluntarily, and efficiently if the free
market is allowed to decide what are the most economical ways to do it. I
think some people will be surprised how fast it goes once renewable energy
is cheaper than fossil fuels.
Since it will take time, we need to get started, in a serious way.
The sooner the better, the sooner we start the less drastic and fast the
change has to be and the easier it will be.
