How many 'green energy' proponents are willing to look at the real cost of producing all that 'green energy'. It requires a maximum sized semi flat bed trailer to transport a single blade of the typical wind turbine, and that one blade is ALL that truck can transport. What energy was required to acquire and process the materials that went into that blade as well as the manufacture of the blades themselves which are most often mostly fiberglass reinforced with 'gasp' carbon fiber? How long does the wind turbine have to operate in order to offset the 'ungreen' processes used to build, transport, install, and maintain it?
Each tall wind turbine, including a safety margin around it in case it falls, requires about a half acre of land plus roads leading to it. A wind turbine to provide all the electricity for a single house costs something like $30k to build and $300 to $900 per year to maintain. It will be a long time before a homeowner will recoup their investment via lowered electricity costs or the environment will recoup in green energy considering the energy 'pollution' necessary to manufacture and install the turbine.
For that matter the huge turbines that can generate enough electricity to power 300 homes generally cost something like $3 to $4 million each. Given the fairly high maintenance on these things, how long will it have to last to recoup the carbon savings. How long to recoup the cost in electricity production given that these things still cost a bit more to run than the equivalent use of coal?
How much do wind turbines cost? | Windustry
A coal powered plant that can provide power for 700,000 homes costs something like $2 billion making it three times more cost effective than the 2000+ wind turbines necessary to provide the same amount of power.

Noise pollution is a problem with wind farms as well as them being placed in places that can really create an eyesore. Several communities in the USA and abroad have reported that their thriving tourist industries declined significantly after wind turbines went in and spoiled pristine views. And many places have passed ordinances prohibiting them from being located near residential areas due to unknown negative effects of them on people.
The upside is wind is free. And while it takes a hell of a lot of wind turbines across a large expanse of land to produce as much electricity as one coal fired power plant, wind turbines are at least more efficient and less costly than solar power and take up less room to produce the same amount of energy.
I read somewhere that we would need something like a billion wind turbines to replace coal and coal, I believe, accounts for less than 50% of all electricity production. I haven't done the math, but I'm guessing that enough wind turbines to replace coal would take up a whole lot of good farm and pasture land. That's probably why small countries with a coastline and populations approximating a large U.S. city or medium sized state are putting their wind turbines out in the ocean.
And as for the heavily tax payer subsidized ethanol, there is even less reason to push that as a CO2 reducing, green energy component. See this scientific test on that run by Edmunds:
E85 vs. Gasoline Comparison Test
And the costs cited in their study don't even include the cost to us tax payers in direct subsidies or the more expanded much higher food costs in both grains and proteins when food crops are diverted to production of ethanol. And a huge chunk of those subsidies are going to those much maligned oil companies.

Seriously folks. We need to use some common sense and honesty in evaluating this stuff. "Green" is green only if it actually helps the environment in necessary ways. When it fails to do that, no amount of propaganda, 'feel good' rhetoric, or noble sounding titles makes it something any of us should be forced to do.
