Investment in Clean Technologies
The trends we are seeing reflect a broad spectrum of innovations, beyond energy generation (nevertheless a central pillar of clean technologies) to new commercialization models, to energy efficiency, to new applications of advances in materials sciences and molecular structures, and to resource sharing platforms enabled by the web.
More Power to You: Marines Boost Energy, Lighten Load

Empowering Rural Cambodia with Solar lighting
As Cambodia is located in one of the sunniest areas of the world, solar power provides an excellent solution to the reduction in kerosene use: it's safe; reliable; and easy to use.
What is osmotic power?
There are enormous benefits with osmotic power, namely that it's the cleanest, most reliable source of renewable energy on the planet, it is always available and more cost-effective than solar or wind power, has a small ecological footprint and it recycles natures resources (seawater or wastewater).

Utilities Spend Big In Arizona Solar Energy Fight As Final Decision Looms
Utility commissioners in Arizona will decide the fate of rooftop solar incentives this week, in what has become the biggest fight over renewable energy policy in the country. A two-day hearing on the issue at the Arizona Corporation Commission began Wednesday.
The Arizona Public Service, the state's largest utility, is asking the commission to change the current policy, which allows homes and businesses with their own solar power systems to sell any excess energy they generate back to the grid. That policy, known as net metering, was first put in place in 2009. The utility argues that customers with rooftop solar aren't paying their fair share to maintain the grid, and has proposed policy changes that would increase prices for those with solar systems. But local solar advocates have accused the utility of trying to kill the state's burgeoning solar industry, and have launched a counter-campaign.
As The Huffington Post has previously reported, the fight got interesting when the utility revealed that it had been secretly funding anti-solar ads produced by a national conservative group. After a commissioner asked the company and other groups involved in the net metering debate to disclose how much money they were spending on the issue, APS disclosed that it had spent $3.7 million on PR work. The solar lobby disclosed that it was spending nearly half a million dollars on fighting the proposed changes.
After Fukushima, Japan Finds Beauty in Solar Power
It looks like some idealistic architecture student’s vision for the future of sustainable energy production. In fact, it's a photo of a real-life solar plant that went into operation on Nov. 1 in Japan.
The Kagoshima Nanatsujima Meg a Solar Power Plant , built by the electronics manufacturer Kyocera, boasts postcard views of Kagoshima Bay and Sakurajima volcano. It’s also Japan’s largest, with a capacity of 70 megawatts. That’s enough to power some 22,000 Japanese homes. The $280 million project is part of a national effort to invest in clean, renewable energy as the country continues to grapple with the fallout of the Fukushima nuclear disaster. The country’s new feed-i n tariffs have made it one of the world’s fa stest-growing solar markets .
This sort of sprawling solar-panel farm is hardly the most efficient form of power generation in terms of either cost or the amount of land required. Still, it makes more sense when you consider that Japan has been dealing with soaring energy prices in the wake of a disaster that threw into question its entire nuclear-power program into question. While solar is clearly more expensive than nuclear power, the Washington Post noted in June: Most consumers think that sacrifice is worthwhile, and they say nuclear power has hidden cleanup and compensation costs that emerge only after an accident. Fossil fuels, meanwhile, release harmful greenhouse gases and must be imported from Australia, Russia, Indonesia and the Middle East.
In other words, this gorgeous solar plant is what happens when a country comes face-to-face with the full societal costs of more traditional power sources.
Fukushima Floating Offshore Wind Turbine Starts Generating
A development to harness the power of the wind about 20 kilometers (12 miles) off the coast of Fukushima, site of the March 2011 nuclear disaster, began generating power on an operational basis today.
The project, funded by the government and led by Marubeni Corp. ), is a symbol of Japan’s ambition to commercialize the unproven technology of floating offshore wind power and its plan to turn quake-ravaged Fukushima into a clean energy hub.
“Fukushima is making a stride toward the future step by step,” Yuhei Sato, governor of Fukushima, said today at a ceremony in Fukushima marking the project’s initiation. “Floating offshore wind is a symbol of such a future.”
The 11-member group’s project so far consists of a 2-megawatt turbine from Hitachi Ltd. )nicknamed “Fukushima Mirai.” A floating substation, the first of its kind, has also been set up and bears the name “Fukushima Kizuna.” Mirai means future, while kizuna translates as ties.
The group is planning to install two more turbines by Mitsubishi Heavy Industries Ltd. with 7 megawatts of capacity each. The Ministry of Economy, Trade and Industry has said the floating offshore capacity may be expanded to 1,000 megawatts.
Microinverters and DC Power Optimizers Will Reach Nearly $2 Billion in Annual Revenue by 2020, Forecasts Navigant Research
Microinverters and DC optimizers, commonly referred to as module-level power electronics (MLPEs), increase the energy harvested by solar PV modules and reduce the levelized cost of electricity by converting or conditioning power at the module level. As a result, microinverters and DC optimizers are two of the most disruptive technologies in the solar PV sector today. Click to tweet: According to a new report from Navigant Research, revenue from microinverters and DC optimizers will grow from $308 million in 2013 to more than $1.9 billion in 2020.
"The module-level power electronics sector has grown from a niche market to mainstream, especially in the United States, where there is fierce competition in major solar PV markets like California," says Dexter Gauntlett, senior research analyst with Navigant Research. "What's more, a growing number of solar PV module manufacturers are now integrating microinverters and DC optimizers at their own production plants. At the same time, large power electronics companies and incumbent manufacturers are making strategic partnerships and acquisitions to take advantage of rapid growth in this market segment."
Microsoft buys first wind PPA in green push
Microsoft has announced it has signed a 110MW PPA with RES for a project in Texas, following Facebook and Google into wind power.
The 110MW Keechi wind farm, located 70 miles northwest of Fort Worth, will power a Microsoft data centre in San Antonio, Texas. It follows the company's announcement last year that it planned to become carbon neutral.
Construction of Keechi will begin early next year and will use Vestas 2MW turbines. The PPA is for 20 years.
This is Microsoft's first move into wind energy. In doing so it is following a path set by Google, which has bought around 570MW of wind power in Texas alone. It had also invested and bought wind farms elsewhere in the US.
SunPower Buys Greenbotics for Solar Panel Washing Robots
SunPower Corp. (SPWR), the second-largest U.S. solar manufacturer, bought Greenbotics Inc., maker of robots that clean panels to increase the amount of power they can generate.
The robots clean dirt and dust off of photovoltaic and solar thermal arrays and cut water use by 90 percent, San Jose, California-based SunPower said today in a statement. Terms of the deal, the seventh acquisition SunPower has done since it was formed, weren’t disclosed.
SunPower plans to use the systems at projects it develops, especially in the western U.S., the Middle East and Chile, as an alternative to pressure washers and sprayer trucks. The robots will cut water use, save money and boost annual energy yield in dry, dusty regions by as much as 15 percent, according to the release.
“It’s half the cost of normal cleaning,” SunPower Chief Executive Officer Tom Werner said in an Nov. 1 interview. The technology, which he likened to a Roomba vacuum cleaner, “is one we can scale.”
