Google Goes Green
foobsr writes "Google today announced its RE<C project to make renewable energy cheaper than coal in the near future. The company, and its charitable arm google.org, plan to invest hundreds of millions of dollars in the initiative. Larry Page stated: 'With talented technologists, great partners and significant investments, we hope to rapidly push forward. Our goal is to produce one gigawatt of renewable energy capacity that is cheaper than coal. We are optimistic this can be done in years, not decades.'"
"Clean" coal is still extremly dirty, EVEN if you ignore the carbon issue. For instance, Clinton had passed a law that was going to force ALL of America's coal plants to cut way back on mercury emissoins. W. killed that almost right away when he took over. The reason is that it was estimated to jump electric prices up by 25%. Bear in mind that Clinton's clean up would not have stopped the mercury, just cut it in half. Right now, even in America, we do not do a good job of cleaning up our emissions, BECAUSE of the costs. And countries like China simply skip it all togehter, even though they have billions in the bank and are giving it to other countries to obtain their resources.
Best thing that America can do is get off coal (and natural gas is not the way to go, but better than coal). Nukes would help.
I prefer the "u" in honour as it seems to be missing these days.
Peak Oil is debated - have we already reached it, will it be in 10 years, 20 years? I tend to think we are living through it more or less now. However, I heard a representative from BP speak recently that indicated that, if demand drives the cost of oil up enough, there's enough tar sands and oil shale out there to push peak oil back a long ways. Sure, that's BP talking, and oil shale and tar sands are shit kinds of energy, but it is a facet of the debate.
Peak Coal, on the other hand, is decades or centuries off. The United States has enough coal reserves that we could be energy independent for a few hundred years. China, India, and Russia have lots of reserves, too.
Of course, there are prohibitive problems with becoming an all-coal energy economy for a few hundred years. I advocate that we move away from coal (and oil) as fast as possible. The point is, though, that there's still a lot of coal out there.
$29 Billon at the last count. It has the same budget as the entire WHO and dwarfs the amount the US government spends on aid.
Gee, building a maglev train in the richest part of the world's richest country to carry the world's richest, fattest taxpayers, wouldn't THAT be a gift to humanity?
are widely recognized to be almost at, at, or past peak production on a global level,
I find it interesting that so many people have such a poor concept of the current situation. What people fail to recognize is that we are artificially reaching peak production. Contrary to popular belief, the world's most cost effective refinery was shut down less than a decade ago. No new refineries in the US are being built. Keep this in mind when you contrast this with the fact that more oil is currently known to exist than any other time in human history and its widely believed huge undiscovered reserves have yet to be located.
Right now, artificial scarcity is causing production peaks. Artificial scarcity helps keep fuel prices high so oil companies have zero incentive to create new refineries. What most people also fail to understand is crude comes in varying qualities. The per barrel price you constantly see quoted represents the highest grade crude. What you don't see is the "junk" crude is often half or a quarter the price. The low quality crude can be processed but requires special refineries. In the US, we only have one or two refineries which can process high sulfur crude. Processing high sulfur crude is actually equally profitable but requires additional investment from the oil community a it requires expansion in processing capability.
Long story short, there is actually zero factual information to suggest we are anywhere near peak. What the misinformed often quote as peak are simply observing artificial limitations which are kept in check by the oil companies and further compounded by their refusal to increase production capabilities while having reduced capabilities less than a decade ago. The only question is, how much are you willing to pay for your fuel?
With oil prices as they are now, most of the known oil sources become viable, but again, no one wants to do that because what is already available is far more profitable. And heck, if you can use up your competition's supply, it makes your reserve all the more valuable down the road.
Is greed really so easily confused for peak production?
Google invested heavily in a company called NanoSolar back on 2002. Since then, Google, along with some of the top investors, have given Nanosolar millions and millions of dollars to produce printable roll-out solar cells that uses a conductive foil instead of silicon, making the cells much cheaper and easier to make. For information on Nanosolar's history, you can go here.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
I work for a major public power company and have worked on some renewables projects in departments concerned with supplying retail load (e.g. you, your aunt, Google, etc.) What so much of this debate forgets -- either deliberatley or inadvertently -- is that electricity can't be stored in any useful quantity. It's unique among commodities.
Thus it follows that the main problem with 99% of renewable energy is that it is not dispatchable. When you're working for the power company and suddenly load spikes, you need to be able to call on a resource immediately. We have dozens of internal procedures (and a load of regulation) that dictate how much "ready to go" energy we must have available at any point.
As a utility I can't count of a solar plant to be there as a reserve -- even in the Southwestern U.S. -- nor wind. (Geothermal is a notable exception -- it's as reliable as coal or nuke -- but is only available in specific locations.) Sure, if I could store the energy produced by a wind farm until I needed it, great, but that's not a possibility.
I doubt that Google (or any business) will be willing to accept the operating risk of not having some form of dispatchable energy ready at hand. So they've got two choices:
Utilities, for the most part, regard renewable energy projects as really expensive press release opportunities. Utilities are required to be reliable and, for the most part, are run by men and women who take pride in the fact that when you, Joe Customer, turn on your kid's night light, it comes on. Until someone figures out how to store energy from a wind or solar farm, the energy driving that night light is going to be baseloaded on either fossil or nuclear fuel.
Good points.
Part of the problem is that we don't have an accurate accounting of how much oil is left in the easy-to-get-to locations. The middle eastern sources are depleting, but they refuse to acknowledge how much. Every year they say that the amount of oil left in the ground is the same as it was the previous year. This is because they are limited in how much they can extract by international treaties. If they can only extract 5% a year, then the only way they can keep production up is to claim that the amount of oil is the same. So they lie. We may find that those oil fields run dry all of a sudden and nobody knew it was going to happen.
As you point out, other sources can be exploited - but it requires investment and time to setup. And unless we know how much is left in the easy sources it is hard to gauge when to invest in the hard ones. In the end, it doesn't matter: We need to move to renewable for this reason, and 1000 others.
OK - fine. How many parts per million of uranium is there in sea water, eh? Now, take the number of parts of Uranium you will need to run a reactor. Multiple those two numbers, and you will get the volume of water you will need to boil off to get the uranium you need for ONE reactor.
About 3 parts per billion
That's the first I've ever heard about anybody being crazy enough to try to boil off the water to extract the uranium.

If 2g-U/kg-adsorbent is submerged for 60 days at a time and used 6 times, the uranium cost is calculated to be 88,000 yen/kg-U, including the cost of adsorbent production, uranium collection, and uranium purification. When 6g-U/kg-adsorbent and 20 repetitions or more becomes possible, the uranium cost reduces to 15,000 yen. This price level is equivalent to that of the highest cost of the minable uranium. The lowest cost attainable now is 25,000 yen with 4g-U/kg-adsorbent used in the sea area of Okinawa, with 18 repetitionuses. In this case, the initial investment to collect the uranium from seawater is 107.7 billion yen, which is 1/3 of the construction cost of a one million-kilowatt class nuclear power plant
So, of the order of $1bn to setup and then around 250$/kg to extract using current technology to extract enough uranium to run 6 nuclear power stations.
