Duke Energy Builds 3 Solar Projects in North Carolina

         Duke Energy Renewables, a commercial business unit of Duke Energy, has begun construction of three utility-scale solar power projects totaling 30 megawatt solar energy in Eastern North Carolina. The 20 megawatt Dogwood Solar Power Project is located in Halifax County, near Scotland Neck. The company is also building two 5 megawatt projects, one in Bertie County near Windsor, named Windsor Copper Hill Solar; the other, Bethel Price Solar, is in Pitt County, near Bethel.
          "We are pleased to be expanding our presence in Eastern North Carolina and bringing significant community development benefits to these counties," said Duke Energy Renewables President Greg Wolf. "The projects generate valuable tax revenue, provide supplemental income for landowners and bring clean, renewable energy to the state." Power from these projects will be sold through long-term fixed price contracts. SunEnergy1, a solar design, engineering and construction company based in Mooresville, North Carolina, is building the photovoltaic projects, which are expected to be complete by the end of 2013.
           "When the sun is shining and the plants are operating, the 30 megawatt of solar energy generated by the three projects will supply enough electricity to power about 6,000 homes," said Kenny Habul, CEO of SunEnergy1. "We are proud to be partnered with Duke Energy and applaud their continued commitment to bring economic growth and renewable solar power to these counties that can repeat tangible benefits from the projects."

Google Invests $80 Million to Open 6 Solar Energy Plants

        Google is investing $80 million in 6 new solar plants in California and Arizona that the company says will provide enough electricity for 17,000 homes in the United States. The investment is Google's 14th in renewable energy. The company has so far put more than $1 billion behind solar and wind projects since April 2010. Google is partnering with investment firm KKR for the venture; the lead developer is Recurrent Energy.
       According to a Google blog post, the projects have a combined capacity of 106 megawatts. A typical coal power station produces 600-700 megawatts while a nuclear power plant puts out 900-1,300 megawatts. Google currently gets 33% of its energy from renewable sources, but hopes to be 100% reneawble at some point.

Apple Experiments with the Solar iWatch

       Apple is "experimenting with wristwatch-like devices", the New York Times reported on Sunday, citing people familiar with Apple's tests. The devices would be made of curved glass and, not surprisingly, run on iOS, the paper said. Apple has discussed such a device with its key manufacturer Foxconn, the Wall Street Journal reported in a follow-up pace.

       A wrist watch could make a lot of sense in the context of Apple's search for way to deliver products that are more accessible in lower income markets, Piper Jaffray analyst Gene Munster said in a report last month, the Times notes. Rumors circulated earlier this year that Apple was looking at plastic to bring the cost of an iPhone down to between $99 and $250.

       Apple may have its own energy solution to the power constraints a watch running iOS may face. The U.S. Patents and Trademark on February 5 granted Apple patent No. 8,368,654 for "Integrated touch sensor and solar panel configurations." The solar patent would introduce optical sensing capabilities to the screen as a means to interact with it and to boost its energy generating capacity.

       "The integrated touch sensor array and solar cell stack-ups may include electrodes that are used both for collecting solar energy and for sensing on a touch sensor array. By integrating both the touch sensors and the solar cell layers into the same stack-up, surface area on the portable device may be conserved. In addition to being used for capacitive sensing, the integrated touch sensor and solar panel configurations may also be used for optical sensing," Apple notes in the patent.

         The patent adds: "When an approaching object, such as a finger, is detected the solar panel may switch to a capacitive sensing mode to more precisely locate the object. Alternatively, the solar panel may cycle between solar power/optical sensing mode and capacitive sensing mode."

First Public Auction for Solar Energy Rights on Federal Land

         Federal officials are trying to figure out why the Bureau of Land Management's first-ever auction of public land for solar-energy development failed to attract any bids. According to the Denver Post, no bidders showed up for the first auction for three parcels of land in Colorado's San Luis Valley, even though five solar development companies had expressed interest in the land.
        Three parcels covering 3,700 acres in so-called solar-energy zones were offered on Thursday, October 24. The bureau has created 19 zones for large solar projects in 6 Western states, encompassing nearly 300,000 acres, the newspaper reported. "We are going to have to regroup and figure out what didn't work," Maryanne Kurtinaitis, the renewable-energy program manager for the BLM's Colorado division, told the Denver Post. "It is always tough to be the first out of the chute. This is a learning experience."
       Even though the auction's results seem to be pretty bleak, good news is on the horizon. The Obama administration continues to make it a priority to promote solar energy development as part of its energy strategy. Since 2009, the Interior Department has approved 47 renewable energy projects on public lands, including 25 solar facilities, 10 wind farms and 12 geothermal plants.

Walmart Draws More Solar Power

        Solar power and keg stands have one thing in common: Wal-Mart wants to profit from them. In the race for commercial solar power, Wal-Mart is killing it. The company now has almost twice as much capacity as second-place Costco. A better comparison: Wal-Mart is converting more energy from the sun than 38 U.S. states.
        In the beer department, Wal-Mart recently decided alcohol was good business and vowed to double sales by 2016. The result: 500 reps from the alcohol industry converged on the Sam's Club auditorium in Bentonville, Arkansas for an "adult beverages summit" focused on Wal-Mart. "It's even selling it in garden centers," wrote Bloomberg News in August.
       With solar, will Wal-Mart have the same industry-focusing presence its had with booze? If small business is the heart of the U.S. economy, Wal-Mart is the gluteus maximus (also known as the power muscle). The company defines global supply chains and crunches cost reductions in just about every area it touches. More than 80 publicly traded companies rely on Wal-Mart for 10% or more of their annual revenue, according to Bloomberg data. "When we find something that works--like solar--we go big with it," the company's website proclaims.

U.S. Air Force will Install New Solar Power Storage System

          In yet another demonstration of the U.S. military's transition to renewable energy, the Air Force Research Laboratory is eyeballing a computer center in Hawaii to demonstrate an advanced system for collecting, storing and using solar power. The aim is to show that solar power can contribute to a seamless energy management system for a sensitive, high-demand facility. If the pilot project is successful, it could be implemented at other Department of Defense facilities worldwide and make its way into the civilian sector as well.

Proposed AESM system

           Of all the 50 states, however, Hawaii is the most vulnerable when it comes to fossil fuel dependency and it is also the site of key Department of Defense facilities, notably Pearl Harbor, so the state's transition to locally harvested fuels is a vital national defense issue as well as a boost for consumers and businesses beset by high fossil fuel costs. In that context, it's little wonder that Hawaii was chosen as the shakedown site for the new Advanced Energy Storage and Management (AESM) system.
           AESM also dovetails with another solar project the computer center is pursuing, the Maui Solar Initiative. This will consist of a proposed 1.5-megawatt, 13-acre solar farm located nearby. Aside from reducing fossil fuel dependency in Hawaii, the project is expected to save big bucks for the Air Force, which according to hpcwire.com, currently foots the center's annual electricity bill of more than $3 million.

New York and Solar Energy?

           Owens Corning, the Fortune 500 buildings materials company, is probably best known for its pink fiberglass insulation. Now it's got another claim to fame: the company's Bethlehem, New York manufacturing plant, already the winner of a New York State Governor's Award for pollution prevention, is, as of [recently], home to one of the largest industrial solar arrays in the Empire State.
          The company had flipped the switch on the 2.7 megawatt installation [on October 15] at noon--just as sunshine broke through the clouds, as if on cue. The solar array was approximately 9,000 ground-mounted photovoltaic panels located on more than 9 acres, on a former cornfield close to the plant. The array demonstrates the benefits of pollution-free electricity, producing enough clean power from the sun to supply some 6% of the plant's electricity needs.
          It also demonstrates the benefits of Governor Cuomo's NY-Sun Initiative, without which this solar array would not have come into being. The initiative is currently funded through 2015, but we hope that with one last push from the Governor, NY-Sun will live on as a 10-year, $150-million-a-year effort to finally make New York a solar leader.
          Sunny states like California, Arizona, Nevada, and New Mexico are, of course, early leaders in installed solar capacity, but Northeastern states also have a high potential for solar power. Currently, the great state of New York lags behind New Jersey and Massachusetts in total solar power installed. However, according to the Solar Energy Industries Association, New York is catching up, thanks to NY-Sun and is now #8 in the country for installed solar power, up from #13 at the beginning of 2013.
