Massachusetts to open area the size of Rhode Island to offshore wind power

Massachusetts Deval Patrick and U.S. Interior Secretary Sally Jewell announced plans for a new proposed offshore wind power area of more than 742,000 acres, or 1,160 square miles, which would make it about the size of Rhode Island (1,214 sq-miles). This new area, where space would be auctioned in 4 different leases, would nearly double the federal offshore acreage available for large wind energy projects. Secretary Jewell said that the government has learned from the Cape Wind offshore wind project in Nantucket Sound, which faced over a decade of opposition and lawsuits, and have picked a spot farther from the shore that should not be as contentious. "We put in zones that we believe have both high potential and lower conflict," Jewell said. "But it's going to actually get down to a specific construction plan on a specific site and (an environmental) analysis to determine what people want to do economically and what that impact is going to be.  

SolarCity is trying to become the Apple of solar power

SolarCity is already the largest installer of residential solar panels in the United States. Now the company is going a step further, buying up solar manufacturer Silevo and planning to build one of the world's biggest solar-panel factories in upstate New York. The immediate goal here is vertical integration. The company, which was co-founded by Tesla CEO Elon Musk, wants to handle all aspects of the solar supply chain, from design to manufacturing to sales to installation. It's basically the Apple model — only for solar panels. But SolarCity's ultimate aspiration is to drive down prices dramatically. In a call on Tuesday, Musk said that the aim was "to have solar power compete on an unsubsidized basis with fossil-fuel energy from the grid." (The company was also founded by brothers Lyndon and Peter Rive, who currently run it.) Is that doable? SolarCity has had success with its current business model — offering rooftop solar systems at no upfront cost to customers who make monthly payments spread out over many years. The company now handles 25 percent of all US residential solar installations — and is aiming for 1 million customers by 2018. This latest move means SolarCity will be able to produce its own panels for these systems and try to lower its costs even further.

New Report Finds Thermal Energy Storage Could Add Value To Solar Energy

A new report from NREL, the National Renewable Energy Laboratory, could help spur the development of more utility scale concentrating solar power plants with thermal energy storage features while boosting the market for solar cells, too. The report indicates that CSP/energy storage projects could add value to utility scale solar energy in California, and they would enable more solar cell development by creating additional grid flexibility. California’s ambitious renewable energy goal for 2020 also plays a key role, so keep in mind that the NREL added-value findings for thermal energy storage are transferable to only to other states with similar aspirations.  

Residential Energy Generation and Storage Will Reach $71.6 Billion in Annual Revenue by 2023, Forecasts Navigant Research

Solar photovoltaic (PV) panels, which enable customers to generate some of their own electricity and sell unneeded power back to their utility, are the most visible form of the broad disruption caused by distributed energy resources (DER). The growing affordability of DER technologies is altering utilities’ traditional relationship with residential customers by giving customers greater control of their energy consumption. According to a new report from Navigant Research, worldwide revenue from all forms of residential distributed generation and energy storage will grow from $52.7 billion annually in 2014 to $71.6 billion in 2023. “Rooftop solar PV is just one of the technologies that are transforming the traditional residential power industry,” says Neil Strother, principal research analyst with Navigant Research. “Some of these technologies, such as residential combined heat and power, are in the early stages of market development, while solar panels are more mature. Nonetheless, these energy innovations and attractive financing mechanisms provide residential customers with new options.”   One key driver for this sector, according to the report, is continuing advances in new technologies, such as more efficient energy storage systems (ESSs). These advances, along with government subsidies for ESSs, often in the form of feed-in tariffs, are enabling the combination of rooftop solar PV systems and residential energy storage in order to collect and store energy for use when sunlight is unavailable or there is a power outage.  

Buffett to double his $15 billion solar, wind investments

Warren Buffett is ready to double his $15 billion investment in renewable energy, according to reports.   Speaking at the Edison Electric Institute’s annual convention in Las Vegas Monday, Buffett described how he had briefly lost track of how much Berkshire Hathaway had invested in the sector and  needed a reminder from a deputy. Buffett said he responded “there’s another $15 billion ready to go,” according to Bloomberg News.   Buffett’s investments include wind farms in Iowa as well as solar farms in California and Arizona.   Buffett also vowed to keep investing in utilities. The sector may not make you rich, but it will keep you rich, the legendary investor was quoted as saying in another report.   Berkshire Hathaway’s MidAmerican Energy last year bought two co-located solar-power projects that combined are the largest solar project in the world.  Last month, MidAmerican said it will supply Google Inc. facilities in Iowa with electricity from wind power.

The most efficent wind turbine

A new windmill design loosely based on Archimedes’s screw principle, aims to change this, however. A Dutch startup aptly named The Archimedes has re-worked the concept of the windmill to move away from the traditional concept of using the pressure differential between the front and rear of the device to move the rotors.   The Liam F1 Urban Wind Turbine, modeled after a Nautilus shell, measures about 1.5 meters wide and weighs 75 Kg — an ideal size for installation in a residential setting. The turbine is rated to achieve an efficiency “80 percent of the maximum that is theoretically feasible."   According to the creators, the device is designed to provide enough electricity to power an apartment or small home. “The Liam F1 generates an average of 1,500 kilowatt-hours of energy [per year] at a wind-speed of 5 m/s [16.4 ft/s], which resembles half of the power consumption of a common household.” The Liam can even adjust to wind direction, which enables it to maximize power generation even with changing conditions.   The Liam is priced at Eur 3,999 or about US$ 5,450 and will start retailing by July 1st. The Archimedes says it has sold 7,000 units in 14 countries so far. The company says it has undertaken field tests for efficiency and power generation “over 50 times,” in which it has achieved its rated output and efficiency.
