I seem to recall that I read somewhere that the energy equation, in versus out, is in some cases and places, close to zero or even negative when all is tallied. (That is until government subsides are added in ;-)
Cheers,

Here in the US, we are getting ads from energy companies outlining how much
natural gas may be obtained from sources to be developed by fracking. I think
the general population has no clue about the potential dangers to ground water,
just that we should be developing all the domestic (also meaning Canada) sources
possible to aleviate the $100/gallon crude oil price = $4.00 USD per gallon of
gasoline.
At the same time, we hear about all the oil in the Canadian tar sands, I guess
meaning the US government should pressure the Canadian government to allow
energy companies unlimited development of that energy source.

Fracking or hydraulic fracturing has become a very controversial method
f obtaining "natural" gas from deep shale beds in the USA and elsewhere
n the Americas. New York State has promulgated a moratorium on the
rocess for fear that the drinking water of NYC may become saturated
ith methane and potentially other pollutants. The Province of Quebec
as followed and there is a movement in Canada to ban fracking in all
rovinces. There is an obvious conflict here between environmental
afety (drinking water and greenhouse gases) and big energy business,
ot helped by the Halliburton Loophole in the Energy Policy Act of 2005.
Up to now, fracking has not touched Europe to any great extent but it's
n its way. Three experimental wells have been bored in a densely
opulated part of England, near Preston, Lancs. with fear that the
rinking water for a population of about 335,000 may become
ontaminated. Other proposals are being made in Germany, Poland and
ther EU countries.
I have written a referenced essay on fracking, mainly describing, in
asy terms, the process of how gas can be exploited and outlining its
otential environmental impact. It bears the title "Shale Hydrocarbons"
