I work in the natural gas industry. 1/3 of our gas now goes to generation of electricity. It has recently replaced coal as the chief producer of electricity. Coal costs 1/2 what natural gas costs. So, this translates into higher power bills. This is a shear waste of fuel as only 1/3 of energy burned actually gets to your house as useful energy. Transmission of electricity is actually very inefficient. It is more efficient to take the gas all the way to your house (80%) useful energy, so it is best to have natural gas for heat, water heat, cooking, cloths drying, gas logs, generators, etc. Also, other than the compressor stations to keep the gas pumping, almost all regulation and metering equipment is self sustaining and doesn't require power and wouldn't be affected by an EMP. The compressor stations can easily be grounded as a big Faraday cage.
That being said, natural gas is about $1.34 per gallon equivelant energywise as gasoline. We need to be burning it for transportation fuel to help eliminate imported oil and is only produces about half the carbon dioxide as coal or gasoline. Win-win. We first have to convince utilities, cities, buses, etc, to convert which are the easiest to convert first, because of the fleet use and cost of the compressor stations spread over several vehicles.
This is off subject, but Obama hasn't got an energy plan, which is the most critical of anything any president could do.
It affects the trade balance, as half of what we spend on imported goods is oil.
It affects who our potential enemies are, not giving money to potential enemies, by cutting into their profits and underhanded giving money to finance terroism.
It affects our economy, with more jobs here at home drilling, building pipelines, and using OUR fuel, and spending the money HERE, it snowballs and helps everyone else. More utility workers, more drillers, more pipeline construction which has welders, lawyers, surveyors, heavy equipment operators, inspectors, engineers, steel pipe manufacturers (almost all is made in America), valve manufacturers, flange, regulators, welded fittings, heavy equipment manufacturers. All good paying jobs which provides money for families to have homes, cars, educations, etc. See how it snowballs. Most are also union jobs, which I don't understand unions supporting Obama especially in the oil and gas industries. Just allowing drilling, pipeline construction in America could lower the unemployment 1-2% almost immediately, which can kickstart the economy.
