$this->bbcode_second_pass_quote('waegari', 'T')his scheme may be great for electricity production, but will make hardly any difference for oil.
I seem to recall that in the EU some 60% of all oil consumption is by car traffic alone...
So it would only affect car traffic through a vast, massive and overwhelming restructuring of car technology (having them run on batteries) to be put in place right along with it, or better still: right now. Which in itself would vastly increase the amount of solar energy needed...
Not to mention the unfathomable costs to such restructuring of the EU automotive fuel system.
I'm not sure if you got my point about the greater efficiency of electric cars. You will get 85% efficiency instead of below 30% (often closer to 20 when you look at city trafic with frequent breaking).
So you might get 3-4 times as much distance for each unit of energy. That means you dont need to build an amount of solar energy that equals the current gasoline consumption in energy, you just have to build what equals it in distance driven and that would be something like 1/3 to 1/4th of the energy currently wasted in gasoline cars.
And for the cost of replacing cars... Well you replace cars already. How many percentage of the cars on the road are over 20 years old? That means that in 2026 only a tiny fraction of todays cars will be on the road anyway. So with no aditional cost you can easilly replace the old carpark in 20 years with new electric cars. And with a little bit of price incentives favouring electical autombiles you can speed up the process and get the switch done by 2016 instead (at a huge profit for the whole of society not having to import as much of the scarse and expensive oil- even making the scarse oil supplies less in demand and therefor cheeper).
And for the cost of the infrastructure.. Well the grid needs a bit of extra improvement.. But putting more electricity on the grid has been an ongoing process since the first power cables were set up. Electricity usage is better correlated with GDP growth than oil consumption. The costs of accellerated grid developments are not unmanagable. And definately less expensive than extracting more oil from tarsands, shale-oil, coal etc.
And for the existing petrol-stations... How about refitting them to battery switching stations for extension of range of electric automobiles, removing the argument of having to wait until batteries are recharged? This makes existing infrastructure transition into a similar but now sustainable mode of operation.
