Electric cars have been getting a lot of buzz lately, but a more immediately viable transportation fuel of the future could be liquid derived from coal. Scientists have devised a new way to transform coal into gas for your car using far less energy than the current process. The advance makes scaling up the environmentally unfriendly fuel more economical than greener alternatives.
...
The new process could cut the energy cost of producing the fuel by 20 percent just by rejiggering the intermediate chemical steps, said co-author Ben Glasser of the University of the Witwatersrand in Johannesburg, South Africa. But coal-derived fuel could produce as much as twice as much CO2 as traditional petroleum fuels and at best will emit at least as much of the greenhouse gas.

Glasser's new production method allows them to set a lower limit on the amount of energy that would be needed to transform solid coal into fuel. The very best possible CTL process would require 350 megawatts of input to make 80,000 gallons of fuel; the current process uses more than 1,000 megawatts.
Even with the small efficiency gains, a large, domestic, carbon-intensive source of transportation fuel would throw a wrench into many plans to reduce emissions from vehicles.

No surprise here. I have been pointing out for a long time that the idea that we are running out of energy is a lie and that "green" energy is way more expensive and not as effecient as fossil fuels.
