Google Acquires Wind Power Firm Makani Power

PCMag reports that Google has bought Saul Griffith's alternative wind power company Makani - Google Acquires Wind Power Firm Makani Power

Google is known for putting its resources into some novel technologies like self-driving cars and wearable computing devices. Now, the Web giant is moving into yet another field—wind power. After previously investing in the company, Google has agreed to acquire Alameda, Calif.-based green energy startup Makani Power. ...

Makani, which takes its name from the Hawaiian word for breeze, develops airborne wind turbines that are mounted on self-piloting flying wings tethered to the ground like a kite. Google will bring the Makani team into its secret "moonshot" research lab Google X, which produced Google Glass. "This formalizes a long and productive relationship between our two companies, and will provide Makani with the resources to accelerate our work to make wind energy cost competitive with fossil fuels.

In a statement to PCMag on Thursday, Google confirmed the acquisition and said it's eager to bring Makani on board. "Creating clean energy is one of the most pressing issues facing the world, and Google for years has been interested in helping to solve this problem," Google X Director Astro Teller, said in the statement. "Makani Power's technology has opened the door to a radical new approach to wind energy. They've turned a technology that today involves hundreds of tons of steel and precious open space into a problem that can be solved with really intelligent software. We're looking forward to bringing them into Google[x]."

Makani said the timing of the acquisition "couldn't be better" since its so-called Wing 7 kite-power prototype just completed its first ever fully autonomous flight. The startup has said its wing-shaped high-altitude kite design can produce 10 times more energy than conventional turbines.

Google Quits Renewable Energy Research

The Google blog reports that Google's RE < C program (along with various other projects like Google Wave) is no more - More spring cleaning out of season.

Renewable Energy Cheaper than Coal —This initiative was developed as an effort to drive down the cost of renewable energy, with an RE < C engineering team focused on researching improvements to solar power technology. At this point, other institutions are better positioned than Google to take this research to the next level. So we’ve published our results to help others in the field continue to advance the state of power tower technology, and we’ve closed our efforts. We will continue our work to generate cleaner, more efficient energy—including our on-campus efforts, procuring renewable energy for our data centers, making our data centers even more efficient and investing more than $850 million in renewable energy technologies.

CleanTechnica puts the announcement into context - Google Favoring Clean Energy Deployment over Clean Energy R&D.

Announced in 2007 by Google, RE < C was focused on driving down the cost of renewable electricity (mostly solar and geothermal) to meet the cost of generating electricity from coal. The initiative funded R&D in capital-intensive, early-stage technologies that would enable cheaper Enhanced Geothermal Systems and Concentrating Solar Power projects.

But Google says it’s now shifting its focus to project financing rather than R&D, citing the need for more sophisticated research on CSP technologies beyond Google’s scope, and the rapidly changing economics of solar PV:

Over the last few years, we’ve seen a lot of progress in clean energy. We’re excited that some technologies are so quickly approaching cost competitiveness with traditional forms of energy in parts of the US and the world. Power tower technology has come a long way, too. But the installed cost of solar photovoltaic technology has declined dramatically over the past few years, making solar photovoltaic technology a compelling choice for consumers.

At this point, other institutions are better positioned than Google to take this research to the next level. So we’ve published our results to help others in the field continue to advance the state of power tower technology, and we’ve closed our efforts. We will continue our work to generate cleaner, more efficient energy—including our on-campus efforts, procuring renewable energy for our data centers, making our data centers even more efficient and investing more than $850 million in renewable energy technologies.

Although the news was hidden at the bottom of a blog post, this is a pretty important announcement. (Only at Google would they casually “spring clean” millions of dollars in R&D investments for renewable energy).

Firstly, it shows how capital intensive many of these technologies are. Google invested tens of millions of dollars into R&D for new methods of building CSP plants. Today, we’ve got a number of commercial projects deployed using some of the technologies and methods funded by Google — but even after investing all that money, much of the research is still in the early phases, the company says.

The same goes for Google’s funding of Potter Drilling, a company working on developing a technique for drilling through deep, hard rock called “thermal spallation.” The drill is designed for Enhanced Geothermal projects. Potter has been working on the technique since 2004, with Google investing over $10 million in the company through its RE < C initiative in 2008. But like most development in the EGS sector, progress has been slow and the drill has not been commercialized yet.

Google’s shift away from these projects doesn’t prove whether or not they’ll be successful. It just shows how much money and time goes into bringing new energy technologies to scale.

Meanwhile, the stunning changes in the economics of solar PV have made market conditions far different today than in 2007. Google has since invested more than $350 million into the deployment of distributed solar, investing in SolarCity and Clean Power Finance, and a variety of projects in Germany. (Google also threw $168 million behind the Ivahpah CSP project, showing that it still has a lot of confidence in that technology too).

Enhanced Geothermal Systems in Google Earth

Google Earth has announced an improved data set for geothermal energy in the US, also pointing to this article in Forbes - Enhanced Geothermal Systems in Google Earth.

Back in 2008, Frank wrote about how Google.org was using Google Earth to visualize Geothermal Data in the United States.

Google has continued to increase the amount of data behind the map, making it a more and more powerful tool as times goes on. ...

To see this data for yourself in Google Earth, simply load this KMZ file (which was last updated just a few days ago). Also worth your time is this short article in Forbes that talks a bit more about how EGS could benefit all of us.

What It Takes to Power Google

Technology Review has an article on Google’s (suprisingly low) energy consumption - What It Takes to Power Google.

Google is the first major Web company to reveal exactly how much energy it uses—information that will help researchers and policy makers understand how the massive explosion of Internet usage and cloud computing is contributing to global energy consumption.

Google uses 260 million watts continuously across the globe, the company reported on Wednesday. This is equivalent to the power used by all the homes in Richmond, Virginia, or Irvine, California (around 200,000 homes), and roughly a quarter of the output of a standard nuclear power plant.

By far, the majority of Google's energy use is associated with its data centers, according to Jonathan Koomey, a professor at Stanford University and a researcher who focuses on energy and IT. He says that 80 to 90 percent of those watts are used solely by the company's data centers, based on estimates he made of Google's power use in an August 2011 report. Most of this energy is used in powering the IT equipment in Google's data centers. Google custom builds many data centers, such as a new one in Finland that uses a seawater cooling system, to cut down on electricity costs.

This has enabled Google to be relatively energy efficient, says Koomey, who estimates that the company owns about 3 percent of servers worldwide and uses only 1 percent of electricity for data centers worldwide. "They're operating more efficiently than other data centers," he says.

Other Web giants, including Amazon and Facebook, probably operate their data centers with similar efficiency due to hardware and software customization, and innovative cooling equipment, Koomey says. However, the majority of data center power use comes from non-IT companies running their own data centers less efficiently [which is in turn, far less than that used by equipment in homes and offices].

In its report, Google compares the energy usage of companies' in-house computer systems to the energy used by its cloud servers. It estimates that running Gmail instead of an in-house e-mail system can be almost 80 times more energy efficient. Google says that 25 percent of its energy was supplied by renewable fuels—such as from wind farms—in 2011, and plans to increase that to 30 percent this year.
