It's crazy. It'll never work. They cost too much. They'll crack. They're too delicate. You'll slide off them. Oil companies will never let it happen. Scott Brusaw, an electrical engineer from Idaho, has heard it all before. Over the past eight years, skeptics (like this one) have been telling him his concept for solar roadways — replacing America's roads with solar panels, creating a power grid where pavement used to be — won't work. But Brusaw suddenly has a reason why it will — actually, 2.2 million of them. Solar Roadways' crowdfunding campaign, which closed on Monday, raised $2.2 million — more than double what Brusaw was seeking — in just two months. The campaign, the most popular in Indiegogo's history, attracted more than 48,000 backers from all 50 states and 165 countries. "It's been humbling," Brusaw, 56, told Yahoo News. "Really, really humbling." The success can be attributed, in part, to a cheeky seven-minute video ("Solar FREAKIN' Roadways!") that has been viewed more than 16 million times on YouTube.
Many people, even fanatical advocates of solar power, are unaware quite how close we are to reaching a critical milestone in the industry. Within a fairly short space of time, solar generated electricity will be fully cost competitive with coal-powered electricity -- at least if the governments of the world’s two largest energy consuming nations have their way. Both the U.S. and China have a stated goal of reducing the cost of solar generated electricity to that level, and quickly. How they are going about it says a lot about how each economic system works. In the U.S., despite the complaints of some that a drift toward government control is taking place, private initiative and free markets still rule. The Department of Energy launched the SunShot initiative in 2011, with a stated goal of reducing the cost of solar power to be fully competitive with conventional energy sources by the end of this decade. The program funds grants, incentives and competitions to encourage private sector research that will improve the efficiency and lower the cost of solar energy. The Chinese, faced with what is in many ways a more urgent need to achieve the same thing, have taken a different approach. In a manner more in keeping with their history and current economic system, they are beating the problem over the head with piles of cash until the desired outcome is achieved. It looks, if this excellent Michael Sankowski piece at Monetary Realism is to be believed, as if they are getting mighty close.
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 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.

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 $15 billion ready to go,” according to Bloomberg News. Buffett’s investments include wind farms in Iowa as well as solar farms in California and Arizona. Buffett also vowed to keep investing in utilities. The sector may not make you rich, but it will keep you rich, the legendary investor was quoted as saying in another report. Berkshire Hathaway’s MidAmerican Energy last year bought two co-located solar-power projects that combined are the largest solar project in the world. Last month, MidAmerican said it will supply Google Inc. facilities in Iowa with electricity from wind power.
A new windmill design loosely based on Archimedes’s screw principle, aims to change this, however. A Dutch startup aptly named The Archimedes has re-worked the concept of the windmill to move away from the traditional concept of using the pressure differential between the front and rear of the device to move the rotors. The Liam F1 Urban Wind Turbine, modeled after a Nautilus shell, measures about 1.5 meters wide and weighs 75 Kg — an ideal size for installation in a residential setting. The turbine is rated to achieve an efficiency “80 percent of the maximum that is theoretically feasible." According to the creators, the device is designed to provide enough electricity to power an apartment or small home. “The Liam F1 generates an average of 1,500 kilowatt-hours of energy [per year] at a wind-speed of 5 m/s [16.4 ft/s], which resembles half of the power consumption of a common household.” The Liam can even adjust to wind direction, which enables it to maximize power generation even with changing conditions. The Liam is priced at Eur 3,999 or about US$ 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.
Manufacturing solar panels can be a dirty business, from the mining of raw materials to the chemical-laced process of purifying silicon to the assembly of silicon wafers. Solar energy is a renewable source, of course, but it’s essential to examine the full supply chain to gauge its total environmental impact. One potential concern is the use, containment, and disposal of toxic chemicals. Another is the energy-efficiency of the manufacturing process and the source of the energy used. Researchers at Northwestern University and the U.S. Department of Energy’s Argonne National Laboratory recently examined the solar panel production process in different locations and published their findings in the July issue of the journal Solar Energy. “We estimated that a solar panel’s carbon footprint is about twice as high when made in China and used in Europe, compared to those locally made and used in Europe,” says Fengqi You, a co-author of the paper and an assistant professor of chemical and biological engineering at Northwestern. “While it might be an economically attractive option to move solar panel manufacturing from Europe to China, it is actually less sustainable from the life cycle energy and environmental perspective.” The primary differences, the researchers found, are the less stringent enforcement of environmental regulations in China coupled with the country’s more coal-dependent power sector. “It takes a lot of energy to extract and process solar-grade silicon,” says co-author Seth Darling. “And in China, that energy tends to come from dirtier and less efficient energy sources than it does in Europe.”
