"probably required as much energy to create"......not even close. The energy payback is about 3 yrs and the PV panels should still be producing at 75% of rated output when they're 20+ years old.

Note that the numbers used in the following doc are from pre-2004. The efficiency of making panels has increased considerably since then.

From http://www.nrel.gov/docs/fy04o...

Producingelectricity with photovoltaics (PV) emits no pollution, produces no greenhouse gases, and uses no finite fossilfuel resources. The environmental benefits of PV are great.But just as we say that it takes money to make money, it also takes energy to save energy. The term “energy payback”
captures this idea.
How long does a PV system have to operate to recover the energy—and associated generation of pollution and CO2 —that went into making the system,
in the first place?
Energy payback estimates for rooftop PV systems are 4, 3, 2, and 1 years: 4 years for systems using current multicrystalline-silicon PV modules, 3 years for current thin-film modules, 2 years for anticipated multicrystalline modules, and 1 year for anticipated thin-film modules (see Figure 1).
With energy paybacks of 1 to 4 years and assumed life expectancies of 30 years, 87% to 97% of the energy that
PV systems generate won’t be plagued by pollution, greenhouse gases, and depletion of resources.

Based on models and real data, the idea that PV cannot pay back its energy investment is simply a myth. Indeed, researchers Dones and Frischknecht found that PV-systems fabrication and fossil fuel energy production have similar energy payback periods (including costs for mining, transportation, refining, and
construction).

An EV that's running on a grid that's 100% coal-fired electricity is roughly as clean as the best currently available ICE. The advantage that EV has over the ICE is that its pollutants are centralized at power plants, not being spewed through hundreds of millions of tailpipes in densely populated areas.

It's more efficient to deal with those pollutants at the plants than to try to control it through small catalytic converters which tend to be inefficient when the engine isn't warmed up - but a cold engine is more polluting. There's another boondoggle for you.

Not a big fan of ethanol and wary of using food cropland for growing feedstock for fuel.

They are free to say whatever they want.

But, applying for tax exempt status gets you scrutinized. When all your free speech is about the evils of taxation, and you want the government to waive your obligation to pay taxes, you're blissfully naive if you think they won't take a long, hard look at your dealings.

See pg 18 on the PDF below for a list of "Megadeals" in the US up to the end of 2012.
Boeing got $3 billion in breaks from Washington state back in 2003. And then there's the almost $9 Billion over 20+ yrs that they were just awarded for production of the 777x.

Nevada's governor thinks the return on the Tesla deal will be 80-to-1 which seems VERY optimistic given that Tesla will need a decade to reach the 1/2 milllion cars per year threshold for which they're building the Gigafactory.
