Google's Future Electric Bill

Via Peak Oil Optimist, we discover that Google has been doing some projections about its future electric bills:

"If performance per watt is to remain constant over the next few years, power costs could easily overtake hardware costs, possibly by a large margin," Luiz Andre Barroso, who previously designed processors for Digital Equipment Corp., said in a September paper published in the Association for Computing Machinery's Queue. "The possibility of computer equipment power consumption spiraling out of control could have serious consequences for the overall affordability of computing, not to mention the overall health of the planet."

(snip)

If server power consumption grows 20 percent per year, the four-year cost of a server's electricity bill will be larger than the $3,000 initial price of a typical low-end server with x86 processors. Google's data center is populated chiefly with such machines. But if power consumption grows at 50 percent per year, "power costs by the end of the decade would dwarf server prices," even without power increasing beyond its current 9 cents per kilowatt-hour cost, Barroso said.

I think it is a good thing NEI, quite an authorative organization, doesn't recoil from linking to webpages discussing the woefully underreported peak oil issue.

While nuclear power can't do much directly to mitigate peak oil (since oil isn't used much to make electricity, except on islands and in Italy), nuclear power could help indirectly.

Examples of this indirect mitigation is reducing the need for oil heat (either through heat pumps, direct electrical heating, or coolest of all, nuclear co-generation for district heating), by replacing oil for industrial heat, to reduce oil use by tranportation through electric mass transit (subways, trams, trains à la TGV) or even electrical or (the unlikely) hydrogen cars.

Fluor Invests in NuScale

You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Activists' Claims Distort Facts about Advanced Reactor Design

Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...
