This post is the second of a two part series. Read the first installment, Unreported Emissions From Natural Gas Blow Up BC's Climate Action Plan.
Methane leaks from British Columbia's natural gas industry are likely at least 7 times greater than official numbers increasing the entire provinces' carbon footprint by nearly 25%. That's like putting 3 million more vehicles on BC's roads.

wind turbines
Just for a little perspective, each and every windmill needs roughly 280 tonnes of steel, 180 tonnes of coking coal and 300 tonnes of iron ore; all of which need to be mined and transported with hydrocarbons. Unfortunately, we can’t make windmills from solar panels or vice versa.
As for China, environmentally they’re on a “treadmill to hell”; at this point the politburo’s impulse to expand national fossil fuel based energy supplies FAR outweighs any newfound concern for the environment. This is a simple and undeniable fact, especially in light of Chinese neo-mercantilism..
Hard to believe
BioDevastation, your numbers are hard to believe. What is your source for them? And what is all that coking coal used for? And how much steel, iron, etc., and carbon emissions for transport goes into building a nuclear plant, or an oil pipeline, or a coal-burning electrical plant?
Mesa Water...pipeline alongside powerline
The Pickens (and employees) company, Mesa Water, has been buying water rights over the Ogallala aquifer, in the Panhandle. The plan was to sell the water to Texas cities, such as Dallas.
The wind-power powerline could choose its own route, since it would have the right of eminent domain, in Texas. The plan was to locate the water pipeline alongside it.
Could his change of mind over wind power be somehow water related?
Wind power payback
All life cycle assessments for wind energy that I have seen produce an emissions pay-back time of a few years at most. E.g.:

The primary energy used in the production and disposal of materials comprising the offshore wind farm is 43,873 GJ. The yearly electricity production of 12,500 MWh of the wind farm is converted to primary energy that would be consumed at a conventional power plant in order to estimate the energy payback time. Based on an estimated efficiency of 40%, the energy use is paid back in 0.39 year, or less than 2% of a 20-year lifetime. The efficiency used is rather low, but it is the same as used in the LCA model for material production. The land-based wind farm, with a yearly production of 19,800 MWh, is paid back in 0.26 years. These figures correspond to those for a wind turbine in roughness class 1 calculated by the Wind Power Industry [4], although they estimate the figures in another way using input–output tables and an efficiency of 43.5 %.

The comparison of energy used in manufacture with the energy produced by a power station is known as the 'energy balance'. It can be expressed in terms of energy 'pay back' time, i.e. as the time needed to generate the equivalent amount of energy used in manufacturing the wind turbine or power station.
The average wind farm in the UK will pay back the energy used in its manufacture within six to eight months, this compares favourably with coal or nuclear power stations, which take about six months.

So, after the first year (or less), we're in the black!
Engery Usage
What we need to do is use all or any engery source more wiselly. We use more energy then any other country. We need more mass tranportation. I live in a small town and am 50-60 miles any larger city. WE have no buse or cab. to take you to the larger cities without coasting a lot of money. It is to far to ride a bick. WE should uses wind where and when it is coastely to do so. We can use water where there is enought curents to do so. We can use solar power where there is enought sun to do so. We can make and use smaller cars.There are a lot of ways to cut down on engery usage. We waist more energy of all types then any other country. We stick our nose in a lot of place where it dose not belong. By getting into allthes wars who are we really protecting the averge American or Big golbal comporations. Large corpation care only about thier wants and needs. The Koch Brother only care about making more money for themselfs
