Absolutely. Yes. Just shovel that coal into the bus's engine just like your grandpa used to do. That's how we roll with electric buses in the 21st; no need for solar, wind, nuclear, hydro, right?
I'd said that those numbers were old but I highly doubt that it's been less than 1 year payback time for the past 20 yrs. Do you have numbers to back up that claim?
"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.
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.
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.
Have a look at the history of when American coal plants started installing scrubbers and figure out when they reached 10%, 20%, 30% of plants etc, old & new, that were properly outfitted. You'll find there's more than enough blame to go around.
Extent coverage has a %age range which used to be as low as 15% (I vaguely recall) but is now typically a minimum of 30%. So the actual volume can vary considerably when you have a region of millions of sq km which is an average of 40% covered vs one that may be 75% covered by ice.
But, yes, the amount of "old" aka multi-year ice is an important factor.
Up until my late twenties, that worked fine for me but the further into my 30s, the more I had to watch how much I ate and when despite keeping active. A young man's metabolism can be a wonderful thing, but it doesn't last forever.
Huge amounts of grid storage are probably not required in the short term but having some cheap storage to handle short-term fluctuations will make the grid operators jobs easier and will keep down the peak costs.
Now if something like Isentropic's Pumped Heat Energy Storage pans out and is cheaper than batteries, that would be a radical shift in the electricity market. Where could you not find a place to build 2 large-ish tanks filled with gravel & argon? Every large wind farm, power plant or community could build its own local energy storage and there's not a huge upkeep on a system based on pebbles & inert gas.
Wrong. If you look at the winter & spring periods, all the recent years had more ice than 2006 and yet they all finished much lower by the end of the summer melt.
That means more heat in the system - and you should research just how much heat is needed to melt ice. HINT: it's a LOT
This is only ice extent, which is probably the worst indicator of the decline in Arctic ice. Total ice area and volume are far better but more difficult to get accurate numbers.
Here's also what the story says: "State Police said in a statement that Bergeron, an experienced hunter who lives in the area, did not see the victim, and mistook the tails of her two dogs as the tail of a deer."
So this "experienced hunter" can't tell the difference between the ass end of TWO dogs and a deer?? If he's telling the truth, he shouldn't be allowed to hunt unaccompanied AND when it's not well-lit.

And it didn't shut down the French nuclear industry at all.

For some types of lithium-ion, the effect isn't that severe, especially if you don't fast-charge above 80%
Many bus routes are short & fixed so you can have install fast chargers at several points along the route. But I do like the idea of battery swapping.
Diesel engines are powerful but they pollute A LOT. And don't forget ships. That bunker fuel many of them burn is NASTY.

Peak daytime costs are much higher than the evening in most of the sunny parts of the USA.
The IRS scandal is pretty much all hogwash. But it was handled badly.

As for the CIA, they're not directly under the President's thumb - the director is a Presidential nominee but must be confirmed by the Senate.
What's Obama's involvement in this? Is he putting pressure on the CIA to squash news stories?

Boeing took Washington State for all they were worth and were the beneficiaries of the 1st & 3rd largest incentives in US history.
