[rebuttal to a rebuttal that was in the "melting season thread"]
No it isn't. Even if you ignore the externalities (deaths from particulate inhalation, CO2 emission, digging up and burning entire mountains), it still isn't all that cheap.
If you look at the figures, all of the renewal energy in the UK amounted to about 2% of energy consumed in the UK. I did a simple calculation of wind power required to replace UK baseload power based on the average figures of wind turbine efficiency in the UK recorded over time. The end result was one turbine every 500m over the entire surface of the UK. Even then you only get power when the wind blows and that is not every day.
Simply put, in relative terms, BAU coal is not that expensive for the huge power it produces. Coal is flexible, ramps up and down and is very high in power density.
Nuclear, on the other hand, comes with astronomical construction costs, long lead times, huge decommissioning costs and is subject to the cost of Uranium fuel. The window of Peak Urianium is much smaller than that for Peak Oil. Which would then drive Nuclear fuel prices massively.
So, as I say, Coal is cheap in relative terms as a fuel. The UK, for instance, in the late 1970's, was estimated to have 300 years of Coal reserves left at 1970's consumption rates.
The exponential growth in vehicles parallels the exponential growth in electric vehicles. And electric vehicles can be powered from non-dispatchable technologies like wind and sun.
I was talking about China rather than world wide as this was the breathing thing. OK so look at the numbers. In 2015 the number of EV's is expected to reach 800k world wide. In 2015 the number of vehicles on the road is 1.2bn. In 2014 71million cars were sold.
There is not enough land free to spread wind turbines on or to put out solar panels on to feed this kind of usage. Not in developed economies like the EU who emit much of the CO2. This is why I pointed you to the energy use chart for the UK. We'd have to increase the renewable energy by 1,400 times it's current capability just to even have a slight chance of meeting the demand of a full EV switchover.
Obviously not representative of most of the world. If I remember correctly, the latitude of the UK is somewhat further north than, say, China, India, the United States, Brazil, Australia, Africa...
Yes, but as one of the top ten emitters of CO2, it has to be considered a very prime representation of what needs to be done to resolve the situation.
You left carbon fiber out of you analysis. You've read Amory Lovins? who includes commercial vehicle traffic in his analysis as well? http://www.rmi.org/Winning%20the%20Oil%20Endgame
I had a quick peruse of the site. It is a grand design but the realities are in the details and there are unsubstantiated statements in there like "Super efficient transport". The reality of that is the transport industry is not even close to closing the gap between where we need to be and where we are. The IC engine is reaching the limit of what they can squeeze out of it and a replacement except electric is not there.
It's not entirely clear to me that we have to be completely off coal within 5 years. Do you want to explain that?
Jim explained that with the link. The UK is meeting it's obligations to reduce emissions by closing down coal powered stations and replacing it with? Well pretty much a lack of emergency capacity in the system in winter.
Ah, so you have bought into that whole thing that any form of cooperation between people outside of a corporation is communism and inherently evil.
No actually I'm an observer of people and governments. Nobody does anything for nothing and governments think in how much revenue they can claw back and not how much new revenue they can generate. It is not a match made in heaven.... I'm all for cooperation outside of major corporations but it's just not going to happen without the Government footing the bill in the long run.
I'll accept this last argument. I find it well-argued and convincing. (I would say "perceived sacrifices".)
Very sad and bitter experience......
