This year's World Market Updated includes a full chapter dedicated to Direct-Drive WTG versus Gearbox-Equipped WTG. The increased use of the direct-drive turbines across the wind market is impacting the wind industry. The World Market Update 2010 identifies and compares the pros and cons of both the direct-drive and gearbox-equipped concepts, as well as the implications of using permanent magnets on a large scale.
This is an interesting use of existing technologies combined to build a viable solution.
Short description of recent trade show visits, highlighting increased supplier and customer awareness of distribution automation as stepping-stone to renewables integration and development of smart grid
Renewable sources such as solar, wind and hydropower could fulfill almost 80 percent of the world's energy demand by 2050 with the right policies, according to a U.N. report which won backing from governments on Monday. The 26-page study, by the U.N.'s Intergovernmental Panel on Climate Change (IPCC), broadly matched a draft written by scientists. It was approved by government delegates at talks in Abu Dhabi. Environmental groups hailed the report as a guide to the shift from fossil fuels to combat climate change, a process set to cost trillions of dollars. But they said some draft findings were watered down, partly due to opposition by oil exporters. "Close to 80 percent of the world energy supply could be met by renewables by mid-century if backed by the right enabling public policies," the IPCC said. The report said moves to cleaner energies including geothermal or ocean energy would help cut greenhouse gas emissions, which it blamed for global warming including floods, droughts, heat waves and rising sea levels.
U.S. venture capital investment in cleantech companies increased by 54% to $1.14 billion in the first quarter of this year (Q1'11), from $743.3 million in the first quarter of 2010 (Q1'10). This increase occurred despite a 13% decrease in deals year-on-year from 79 to 69, according to an Ernst & Young LLP analysis based on data from Dow Jones VentureSource. The top 10 deals in Q1'11 totaled $683.1 million, 60% of the total raised for the quarter, and two deals accounted for 18% of the total dollars raised. "The U.S. cleantech market experienced continuing momentum - both from a venture capital perspective and among the larger investment community," says Jay Spencer, Ernst & Young LLP's Americas cleantech director. "The second generation of solar companies and larger, later-stage rounds dominated VC investor interest in Q1." The energy/electricity generation segment, led by strong solar investments, raised $450.3 million through 16 deals in Q1'11. The solar sub-segment accounted for 32% of the total dollars raised for the quarter with $362.7 million, a 162% gain from Q1'10.
Changes in solar incentives in key markets such as Germany and Italy are making life difficult for major players such as First Solar, which reported a flat first-quarter revenue and lower earnings on Tuesday afternoon. "With a lot of pending changes, the market started out really slow in 2011," said Rob Gillette, First Solar's CEO, during a conference call with analysts. "We expect the European industry demand to go through a period of adjustment in the second and third quarter." Manufactures saw solar panel prices falling faster than expected, Gillette said, and the lower selling prices were partly responsible for the company's financial results. Europe is the largest solar market, a result of a type of incentive policy that requires utilities to buy solar electricity at government-set, premium prices. The prices are supposed to fall over time as the market grows and production costs drop, but political leaders in Europe in recent years have taken to making extra cuts to curb explosive growth and minimize the impact on consumers, who help to pay for these incentives through their electric bills.
The 2012 Mitsubishi i in the ES trim level will have a base price after federal tax credit of only $20,490 - a substantial savings compared to some of its EV competitors. Further, the optional SE trim level includes a dynamic 360-watt, 8 speaker deluxe sound system, leather-wrapped steering wheel, higher quality upholstery with silver accents, two-tone interior dash and door panels, 15-in. alloy wheels, and fog lamps at only $22,490 after credit. An optional SE premium package is available for $2,790 and including a quick charging port for ultra-fast Level 3 recharging (80% full in only 30 minutes), HDD navigation system, rearview camera, FUSE hands-free communication with USB port and an articulated steering wheel. Despite the price, the base model Mitsubishi i ES packs a fair compliment of standard equipment and amenities, including electric power steering (EPS), LED rear lights, heated driver's seat, air conditioning with micron filter, keyless entry, an on-board recharging system with 8 amp charging cable plus a 4 speaker, 100-watt AM/FM/CD audio system with MP3/WMA playback. A Cold Zone package is available on both the ES and SE for only $150 including a Li-Ion Battery Warming System and heated sideview mirrors. Mitsubishi is making pre-ordering the all-electric car a simple 4-step process taking only a matter of minutes. The first 2,000 placing an order and taking possession of the Mitsubishi i, will benefit from Mitsubishi's waiving the $99.99 home electrical inspection fee - a charge no one sees coming.
Total SA, Europe's third-biggest oil producer, agreed to buy as much as 60 percent of SunPower Corp. for $1.38 billion, taking advantage of increased global interest in renewable energy. SunPower, the second-largest U.S. solar panel maker, described the acquisition price of $23.25 a share as a "friendly tender offer" in a statement. SunPower surged 40 percent to $22.53 yesterday after the close of regular trading on the Nasdaq Stock Market. The deal for San Jose, California-based SunPower may lead to more solar industry acquisitions as U.S. and European suppliers seek help competing against rival suppliers in Asia, said Kevin Landis, portfolio manager at Sivest Group Inc. "This is exactly what SunPower needed to compete with the Chinese manufacturers that are getting so much support from their government," Landis said in an interview. "It also allows SunPower to double down on the technology improvements they'll need to compete in the long run." Sivest, also based in San Jose, held about 17,000 shares of SunPower at the start of the year. The takeover may trigger similar acquisitions by oil companies that consider renewable-energy manufacturers a way to improve their clean-energy credentials and may profit when surging crude prices reduce demand for fossil fuels, said John Hardy, an analyst at Gleacher & Co. in New York.
It has been the dream and pursuit of many a business and research endeavor, but only varied success has been achieved to create a truly transparent solar photovoltaic cell. Leave it to the brainiacs at MIT to find the solution. Yes, the research and technology hub has done it again, marking a landslide achievement in the world of energy technology with the creation of a clear solar pv cell. Researchers Vladimir Bulovic and Richard Lunt have published their findings in Applied Physics Letters. The duo has apparently created a transparent solar cell with a maximum efficiency (sunlight to electricity) of 1.7 percent. The cell operates within the near-infrared spectrum. However, the cell is still only about 55 percent transparent, similar to tinted sunglasses.T he transparent cell is actually quite unique in its design when compared to tradition cells. Bulovic and Lunt's transparent cell is comprised of organic molecules that harness infrared light while allowing visible light to pass through. The photovoltaic compound is actually coated onto a pane of standard window glass. The researchers are in the prototype phase of this technology, but believe it could potentially be painted onto existing windows to create a low-cost easy-to-install photovoltaic option for both commercial and home solar installations.
GM invited members of the Engineering Society of Detroit out to the Proving Gounds in Milford for test drives. There were 11 Volts and they paired us up for a test drive out into Milford and down to Lake Kensington and out on to I 96 for a few miles and then circled back to the Proving grounds. Everyone was excited by their drive and we were told that virtually every one on the development team had their order in on the new vehicle. It is being built in the Hamtramck/Detroit Cadillac Plant that Coleman Young fought for and the lithium ion Battery Packs are being built in a new Brownstown plant nearby.
The basic principles of Joint Implementation are defined in Article 6 of the Kyoto Protocol. Project participants from two (or more) Annex 1 Parties may jointly implement an emissions-reducing project in the territory of an Annex 1 Party, and count the resulting emission reduction units towards meeting the Kyoto target of the other involved Annex 1 Party/ies.
The NY Times reports that the federal government is pouring $500 million into training for green jobs, and the sector devoted to energy efficiency is estimated to grow as much as fourfold in the next decade, to some 1.3 million people, according to the Lawrence Berkeley National Laboratory.
BrightSource Energy, the California solar power plant builder backed by Google, Morgan Stanley and Silicon Valley venture capitalists, filed for a $250 million initial public offering on Friday. The Earth Day S-1 filing marks first big market test of investors' appetite for a capital-intensive solar technology that has yet to be deployed commercially. It comes as utilities have been turning to increasingly cost-competitive photovoltaic farms to meet their renewable energy mandates. BrightSource was founded in 2004 by American-Israeli pioneer Arnold Goldman, whose Luz International built nine solar thermal power plants in the Mojave Desert in the 1980s and 1990s. The company has attracted blue-chip investors, including French energy giant Alstom, as well as a $1.6 billion federal loan guarantee that is financing the bulk of Ivanpah's construction costs. NRG Solar, a subsidiary of NRG Energy, is investing up to $300 million in Ivanpah and Google last week invested $168 million in the project. In its filing, BrightSource, which has signed deals to supply utilities Pacific Gas & Electric and Southern California Edison with 2,600 megawatts of electricity, disclosed that it controls 110,000 acres in California and the Southwest. That land has a capacity to generate 11,000 megawatts - enough solar electricity to supply nearly 15 million homes at peak output. The cost of maintaining leases on those lands stands at $12.9 million, according to the filing, and BrightSource, which has lost a cumulative $177.3 million since its founding, has total debt and contractual obligations totaling $1.8 billion. Despite its impressive pipeline of projects and prominent investors, BrightSource acknowledged in the filing that its viability turns on the completion and operation of Ivanpah, which will deploy 170,000 heliostats around three towers.
The U.S. Department of Energy is offering $2.1 billion in conditional loan guarantees to support what will be the world's biggest solar power plant, the government's largest commitment to date for to solar energy. The aid will support construction of the first two units of Solar Trust of America LLC's 1,000 megawatt solar thermal Blythe Solar Power Project, the DOE said on Monday. Solar Trust of America is a joint venture between German companies Solar Millennium AG and Ferrostaal AG. "For the first time in mankind's history, a solar power facility will be built at a scale and output capacity equal to the very largest coal-fired and nuclear power plants operating in the world today," Solar Trust of America Chief Executive Uwe Schmidt said on a conference call with reporters. The first two units of the project near Blythe, California are capable of producing 484 MW of electricity using solar thermal trough technology. The project will create over 1,000 construction jobs, 80 operations jobs, and will avoid greenhouse gas emissions equivalent to those generated by about 123,000 vehicles. Solar Millennium's technology makes electricity by using trough-shaped mirrors to heat a fluid that generates steam that turns a turbine. The Blythe project's total pricetag is estimated at north of $6 billion, with the first phase costing about $2.8 billion. The announcement came a week after the federal program to support clean energy technologies escaped the axe in the final U.S. budget agreement for the current fiscal year.
