Shale

Because of the shale revolution, the US has one of the lowest energy cost in the world. While the average cost of electricity in Europe is 48 cents per kWh, the cost in the US is only 17 cents. The use of natural gas for power plants not only lowers the cost of electricity but also has reduced carbon emission to below 1990 levels even though the population has increased by 90 million people. If the US would go to natural gas for transportation the carbon emission would decline another 25%.
