Carbon Emissions Reached Record High In 2010

iONiUM writes "Last year, greenhouse gas emissions rose to a record amount of 30.6 gigatons, according to estimates from the International Energy Agency. From an article at the Guardian: 'Professor Lord Stern of the London School of Economics, the author of the influential Stern Report into the economics of climate change for the Treasury in 2006, warned that if the pattern continued, the results would be dire. "These figures indicate that [emissions] are now close to being back on a 'business as usual' path. According to the [Intergovernmental Panel on Climate Change's] projections, such a path... would mean around a 50% chance of a rise in global average temperature of more than 4C by 2100," he said.'" jamie points out a recent report that the cost of solar cells has dropped about 21 percent this year, leading to predictions that solar power may become cheaper than nuclear and fossil power within five years.

    There are lots of excellent alternatives to fossil fuels coming down the pike: solar, wind, nuclear, geothermal, fuel cells. I like the idea of solar cells on every rooftop, with hydrogen fuel cells in the basement to capture the surplus daytime power and recharge the electric cars overnight. I also like the idea of a windmill at every major intersection, to power a square mile or so of residences and businesses.

    They're building a big solar thermal power plant in the Mojave desert, to accompany several others already up and running. Arizona's building a big one as well.

    Solar photovoltaic technology is advancing, both in efficiency and in cheaper manufacturing costs. I think ultimately solar will provide 20-25% of people's electric needs.

    And transportation is going to be electric, as batteries improve. Hybrid car sales are huge, and every manufacturer is getting into the act. They're somewhat expensive today, but economies of scale and improvements in the tech will only bring down costs and increase profits. Probably in 20 years every car on the road will be either a hybrid or fully electric.

    What'll be interesting will be to see just how much impact this eventual shift away from combustible carbon fuels has on the climate. The scientific community largely agrees that humans have caused global warming, but what happens if we stop being the cause and it still gets warmer? All that carbon we've already produced is to blame? Or is it a few major volcanoes in the past century? Or climate shifts that have little to do with human activities?

    I'm all for solar and wind evergy, but they cannot replace hydroelectric, fossil fuel, and nuclear generating facilities. They can only suplement them. The primary challenges, beyond cost, are as follows:

    1. Supply cannot be adjusted to demand. My understanding is that wind is especially bad for this, as it is windiest in the evenings, after major industrial energy consumers have closed down for the day. We currently have very few options for storing generated power for later use. Batteries and capacitors are nowhere near ready for this task. There are a few hydroelectric stations that pump water up in to large resevoirs during the night for use during the daytime surge in demand. The areas where wind and solar are most effective, there is often little in the way of hills and water, making resevoir-based energy storage impractical. Also, resevoir storage requires the costly construction of a resevoir, pumps, and an entire hydroelectic generating station.

    You might think that wind and solar could be used to provide baseline power, while "traditional" coal and nuclear adjust to peaks. Unfortunately, this is only partially true. Many PLWR and BLWR nuclear designs (almost all American designed plants are one of these two types) are not able to idle. This means that if the load on the plant falls beyond a certain level, the plant must perform a full shutdown or risk heat damage. This might not sound too badm but these same plants take at least a full week to restart, and require lots of electricity to do so.

    Hydro is able to adjust it's output very rapidly, however there are only so many locations where hydroelectric dams can be installed. People often cite massive untapped locations far away from existing populations. Excellent! Now all we need to do is build costly and inefficient long-distance transmission lines to carry that power to where it will be useful.

    Coal is also able to adjust output quickly, but, well... it's coal.

    2. The second problem is that of dealing with a phenomenon called "reactive power". This is when voltage and current on an A/C line are thrown out of phase. Ideally, as voltage reaches it's peak, so does current. If you're voltage and current get thrown more than a few degrees off, you're home outlet may still be delivering 100 volts and 15 amps, but not really either at the same time. First you get 110 volts, but low amps, followed quickly my undervoltage and full 15 amps. This means that the usefull power on the line is diminnished.

    Reactive power occurs as a result of inductive loads such as electric motors and transformers. As the coils in the motors rotate past the magnets, or the electric field rises and falls in a transformer, these devices become generators. This "reactive" generation is always slightly out of phase with the input power, and so the power that they feed back on to the grid causes voltage and current on the grid to skew slightly. Multiply this effect by the number of inductive loads on the grid (refridgerators, industrial equipment, televisions) and you can start to have a real problem.

    Electrical generation sources that employ large turbines are able to adjust the magnets inside their generators to help counteract reactive power by producing power that is out of phase, but in the opposite direction.

    Traditional wind turbines are unable to do this, though I believe some newer designes can, at least to some degree. Solid state inverters such as are used to interface solar cells to the grid are not able to to this at all, and so there is a very real limit to their usefulness on the current power grid.

    Anyhow, I'm all for wind and solar. I just don't think they are able to provide a complete solution. Nuclear seems to be the way to go, but it must be done right. The Canadian Advanced Candu Reactors look like a viable option. They are designed such that they cannot melt down, produce relatively safe waste, and are capable of idling quite safely.

    Solar also requires the homeowner to understand electricity... maintain that battery pack or understand the back feed inverter and know to go downstairs to re-set it after a power failure because it will drop off when power is lost to protect line workers and unexpected backfeed.

    Most installs will be grid-tied and not require batteries. As for resetting the inverter after a power failure, I think most inverters will do that automatically -- and if there are those that don't, that's a minor hassle, but hardly a show stopper.

    It will not happen. solar for the typical dumb homeowner will never happen

    In fact, it's happening now. There are companies that will install the array for you, maintain the array for you, and monitor the array's performance for you, all at no cost to you -- instead, they split the profit from your electric-bill savings with you. There is literally nothing that the 'dumb homeowner' needs to do except sign a contract and then pay less for power every month.

    It is hard to predict when the oil is gone. As you neither know how much more oil is found nor how much the need is increasing.

    However there a simple ways to get an idea. When the oil industrie started, in the time where 1 barrel oil was used up they found 1000 more barrels.

    Right now we spend between 7 to 8 barrels in the time we find *one* new barrel. That includes oil sands and other dirty oil reserves.

    If you do accept history, then you can see that the cost of solar cells has been dropping steadily since their invention and demand has been increasing rapidly since their invention. Initial cost in 1954 was $250 a watt and it has steadily declined to about $1 a watt (for the cell itself).

    Demand has increased at 20 to 40% a year as the cost has gone down. (Demand curve, efficiencies of volume production, etc... basic economics).

    You don't need a crystal ball. Fortunately, there is no "silicon cartel" to restrict the supply of raw materials so people who are expert at manufacturing (such as GE) can predict their costs accurately.

  36. Really? by EdwinFreed · · Score: 4, Interesting

    I have two sets of solar panels - one 10 year old set that's wired up conventionally to a single inverter, and another 8-month-old set that uses per-panel microinverters.

    According to the very nice graphical display of power generation the microinverters provide via a built in web monitoring thingie, I average about four hours each day operating between 90% and peak generation.

    Installation of the original set of panels was a major PITA because UL delisted the inverter after it was installed. Getting a massive piece of equipment down off the wall is easy, getting the replacement back up, not so much. But once that one startup issue was dealt with, the system has been 100% reliable and has required no repairs. As for the microinverters, it's early days yet, but they've been completely reliable so far.

    As for washing the panels, yes, doing that more often increases output, but in my experience, not by that much. Around here the windows need to be washed twice a year so the panels get done as part of that. No big deal.

    And as for all this "resetting after a power failure" - it appears your experience with grid-tie systems is seriously out of date. My 10 year old inverter handles power failures automatically. Aside from monitoring, I haven't had to touch the thing once the replacement inverter was installed. Ditto for the microinverters.

    Finally, you appear to be conflating grid-tie and off-grid setups. I agree that a fully off-grid setup isn't easy. I have battery backup as part of my original system, but since the batteries are only used when there's a grid failure they haven't needed to be replaced. (And most grid-tie systems don't need them at all.) An off-grid setup that charges and discharges the batteries every day is going to require a lot more maintenance. And when solar is the only energy source the system has to be overbuilt in the fashion you describe (just not as much as you claim). And you probably care more about keeping the panels clean when they are your only power source.

    But the vast majority of solar systems are grid-tied, not off-grid. So most of your issues simply don't apply.

    Now, perhaps you'll say my experience is unusual. Yes, it's only anecdotal, but I know three people with similar solar setups in the area, and their systems have all worked flawlessly since they were installed.

    The amount of arable land is increased and plants grow faster and larger

    Really? I suggest you look up desertification - increase in global temperatures seems to be decreasing the amount of arable land, not decreasing it. Also, you seem to be under the impression that the result will be a uniform change of 4 degrees. This is not what the models predict - some areas will cool, others will increase by significantly more than 4 degrees. The average temperature will increase by 4 degrees (according to these models).

    For solar, it would literally be a major break through to provide peak load competitive prices and they are no where near being close to being competitive with base load generation. Even moreso, voltaic requires HALF the price of base load to be competitive with base load as it can only generate power half the time. Only solar-thermal looks to be able to ever be price competitive with base load pricing and even that is just now coming out of the gate.

    You should say that your statements are based entirely on utility scale PV installations. People installing them on their homes only need to beat their retail price per KW (average US value is $0.10 per KWh, with some states at $0.05 and others at $0.30). With panel prices at $2 a Watt and falling and a guaranteed 25 year life (that's the warranty on every PV panel sold) they already make sense to individual power purchasers.

    So lets not be dishonest and use utility power pricing for homeowner economic value because they aren't equivalent. PV panels will be viable at the Utility scale level when they can get the thin film CdTe panels at $0.50 a Watt (which is theoretically possible). The fact that GE just bought the largest thin film CdTe panel producer and plans to build the largest solar panel production plant in the world should help.

Time and again, we've seen the actual increase in atmospheric carbon dioxide and associated warming exceed predictions. It cuts both ways -- it might not as be bad as we predict, but it may be worse.

Perhaps you may need a refresher in physics, but it takes A LOT of energy to melt the amount of ice that's disappeared over the past few decades just in those two areas alone.
