carbon dioxide is not a waste, humans exhale it and plants use it and they produce oxygen
Good, coal is the dirtiest source of energy we have. To suggest that is the way we should go for our energy needs is to be frank, retarded.
Source? Link? I want facts, not opinions.
Source to what? That coal is a ludicrously dirty fuel source? About 1 second on google will yield more results than you can reasonably shake a stick at, but ok...

Quote
These energy consumption data were multiplied by their respective carbon dioxide emission factors, which are called carbon content coefficients by the U.S. Environmental Protection Agency (EPA). These factors quantify the mass of oxidized carbon per unit of energy released from a fuel. In the U.S.A., they are typically expressed in units of teragrams of carbon (Tg-C = 1012 grams of carbon) per quadrillion British thermal units (quadrillion Btu = 1015 Btu, or "quad"), and are highest for coal and lowest for natural gas

MIT interdisciplinary study on future of coal http://web.mit.edu/coal/ Study finds coal impossible to use going forward to meet increasing energy demands due to dirty nature without CCS technology.

etc.
In the future feel free to do your own googling. There is no bone of contention as to the effects of coal, so this is not a point that needs to be argued and sourced, and was mostly a waste of time.
What to be done in place of coal, that is the meat for a real discussion.
guess Obama failed then like usual
You do realize that the Republicans get the say in laws?...
I guess the (R) failed.. like usual.
[sarcasm]No they don't. If they did we'd all be at least millionaires by now if not qajillionairs.[/sarcasm]
Seriously though this is the reason why our country is falling apart. Instead of having two sides that can realize they are not always right and having the ability to listen for valid comments from the other side and then compromising to reach a solution that could actually satisfy most people in the county we are left now with a bunch of grown kids kicking sand in their sandboxes claiming they are the king of the world, not willing to budge one inch. Maybe after we get through the complete collapse we are heading to people will be willing to work together again.
we need two countries. a socialist one and a capitalist one
at this moment we have neither but we have the highly inefficient in between bullcrap

$0.09/kWh is ridiculous in my mind. Not sustainable at all. Higher prices coming your way sooner or later (even inflation-adjusted).
Why is it not sustainable. Wholesale rates (i.e. price paid by utilities to independent power producers) in the US tend to be about $0.05 per kWh. Throw in another $0.03 for transmission & distribution and a penny for taxes and profit. $0.09 is perfectly sustainable for large coal plants, nuclear plants, or hydro.
Now if you want to generate power with high cost natural gas, or renewables well that changes things but given the right energy source everyone can profit and no reason electricity needs to cost more than $0.10 (inflation adjusted of course).
The only reason power is so expensive in CA if they shutdown 3 nuclear plants early (and the state had to pay multi-billion dollar penalties to the utilities to do that which simply gets ammortized over the next decade or so in higher prices). They prohibit building new power plants, and get most of their energy from out of state providers thus paying long haul transmission markup and premium prices.

Coal is not sustainable in the long term whoever is in the office since it is a fossil fuel and there is only so much of it. With that being said the prices of coal produced energy have not gone up in the 4 years that Obama has been in office while many other things have become more expensive. So I am not sure what you mean by your statement.

What I meant was: "not sustainable in the long run" due to the underlying natural resources being limited in supply.
Im also in Maryland and used to pay $.09 but it actually dropped the last 2 months to $.07.

Well we've been at .09 /kWh since I've owned my house which is going on 8 years now. We have a power plant using coal, a good co-op, and a solar farm in our county for power. The co-op is actually putting in the solar power now to, as they claim, to keep the price from going up much past .09 / kWh since once the investment is done I don't think solar really costs anything in labor or other misc expenses to maintain. But I'm not an electrical mastermind so maybe there is hidden costs in solar that I am not aware of.
If you put photovoltaics on your roof in germany it'll take about 5 (roughly) years to pay off if you can sell the power at 0.35 $/kWh (!!!). The panels are expensive and the other stuff you need as well. There are sizeable costs, they're not hidden.
It might make more sense in CA or wherever there is more sun than in germany.

If you think solar power is free or cheap, think again: There's a reason why the german government subsidises solar power with something like €0.35/kwH. It might be a little better in places with a lot of sun, but I doubt you can produce for cheaper than what you pay (as a US-citizen) at the plug.
Also: running miners only when the sun shines is not making good use of hardware and still-low-difficulty.
I assure you: if it's not profitable to mine by buying elictricity, it is also not profitable to install photovoltaics for your miners.
location location location. This probably holds true for lots of places, Hydro cities, and what have you.
CA however is a prime counter example, with "Tiered" pricing on electricity, that rises to > $0.35USD / kWh quite quickly, and a reasonable amount of sunshine, it is quite a simple matter to break even or make hay while the sun shines so to speak on some PV investment. Off the top of my head I'm guessing even a battery system would still be cost competitive with CAs ridiculous power pricing.
I'm guessing there aren't many miners in California. Those prices are ridiculous. I'm only paying .09USD /kWh here in Maryland.
Then you're probably guessing there are'nt many miners in Europe, either. Electricity is around 0.3 $/kWh here in germany and rising (we're stupidly shutting down all nuclear plants until 2030 and trying to substitute with wind and other regeneratives but are actually going to be substituting with fucking coal, natural gas and imports)

So there is a profit there, just a very small one.
And that is with 50 BTC per block reward subsidy. So the drop to 25 BTC will in an instant make mining on GPU something you can no longer do at a profit, regardless of whether your rates are daytime or nighttime, right?
I started mining in Nov 2010.
Have you had any hardware failures from the hardware you started with then?
Yes. Cooling fans are the worst, followed by power supplies.
under warranty? a short term miner this year, 2-6 months a falting power supply not under warranty could cost all their profit
