Solar Power Poses Lower Risk to Birds Than Cats or Cars

Solar-thermal power plants in the U.S. are less likely to kill birds than automobiles, cats or communication towers, despite reports that say the facilities pose a significant threat to avian life.   There were 321 “avian fatalities” in the first half of this year at the 392-megawatt Ivanpah solar project in Southern California, according to a statement Aug. 19 from NRG Energy Inc. (NRG), which co-owns and operates it. Of those, 133 were scorched by heat produced by the plant.   That’s far fewer than reported in an Associated Press article on Aug. 18. It cited federal wildlife investigators who estimated that one bird was burned every two minutes by concentrated sunlight at the Mojave Desert power plant.   The estimates for birds killed by solar power are “inflated,” NRG spokesman Jeff Holland said in an interview.   A greater risk comes from cats, which are estimated to kill hundreds of millions of birds each year. Cars are responsible for about 60 million deaths, according to the U.S. Fish & Wildlife Service, and communication towers add another four million to five million. Wind turbines killed 573,000 birds in 2012.

Solar panel shortage looms even as manufacturers invest in production

The solar industry is bracing for a global drought in photovoltaic panels after a series of high supply years that pushed prices to all-time lows and encouraged installations. Solar panel adoption is supposed to increase as much as 29% this year, which has top manufacturers and installers anticipating a drop in availability of panels. This would be the first such shortage since 2006 when the nascent solar energy industry was just taking hold, reported Bloomberg News. Eight years ago, only about 1.5 gigawatts of solar energy capacity was installed. This year as much as 52 gigawatts is expected to be hooked up and another 61 gigawatts in 2015, according to estimates by Bloomberg New Energy Finance. That is compared with about 70 gigawatts of production capacity currently available, though that estimate could be high since some manufacturers’ equipment is out of date or obsolete. The shrinking supply could hinder the growing rooftop solar panel industry. The scarce supplies often get routed to larger-scale utility projects and leave the residential side with limited availability.

Defective Photovoltaics and Other Flaws Plague China's Push to Build Solar Power

China has bet on solar energy as a cleaner alternative to coal, but whether installed solar panels can meet the country's need for energy is becoming a troubling question. China had installed nearly 19.5 gigawatts of solar panels as of the end of 2013. However, "many solar installations failed to generate as much electricity as planned," said Ji Zhenshuang, deputy director at the Beijing-based China General Certification Center, which examined 472 Chinese solar projects over the past four years. Ji would not specify the percentage but said the figure is not small. The solar projects his company examined include those under Golden Sun, a government-led program that was introduced in 2009 to demonstrate the use of solar energy, as well as utility-scale solar farms run by Chinese energy giants. Although China in recent years has surpassed many countries in adopting solar technology, in a move to help Chinese factories survive tougher export markets and to cut the country's dangerous reliance on coal, there is little public information available on how well the Chinese solar projects function. However, some experts did not seem surprised by Ji's findings.   Cont'd..

Brazil readies big push on solar energy but companies are wary

Grappling with its worst energy crisis in more than a decade, Brazil is making its first big move to develop a local solar power industry that could help reduce its dependence on a battered hydro power system. In October, Brazil will hold an auction to negotiate energy to be produced exclusively by solar farms, the first ever of the kind in the South American country. Power companies have registered some 400 projects for the auction, but many remain wary of the outlook for solar power in Brazil and say they need more clarity on investment conditions and financing before signing any deals. The auction could negotiate up to 10 gigawatts (GW), although industry sources estimate final volumes at a much smaller level, varying from 500 megawatts (MW) to 1 GW. Sun-kissed Brazil has one of the highest solar radiation factors in the world and plenty of land for solar farms, plus large reserves of silicon, used to make solar panels. Yet the country has almost no solar power generation, while its BRICS partner China, for example, added 12 gigawatts last year alone – enough to supply around 10 million homes. cont'd..

Rules prevent solar panels in many states with abundant sunlight

Few places in the country are so warm and bright as Mary Wilkerson's property on the beach near St. Petersburg, Fla., a city once noted in the Guinness Book of World Records for a 768-day stretch of sunny days.   But while Florida advertises itself as the Sunshine State, power company executives and regulators have worked successfully to keep most Floridians from using that sunshine to generate their own power.   Wilkerson discovered the paradox when she set out to harness sunlight into electricity for the vintage cottages she rents out at Indian Rocks Beach. She would have had an easier time installing solar panels, she found, if she had put the homes on a flatbed and transported them to chilly Massachusetts.   "My husband and I are looking at each other and saying, 'This is absurd,'" said Wilkerson, whose property is so sunny that a European guest under doctor's orders to treat sunlight deprivation returns every year. The guest, who has solar panels on his home in Germany, is bewildered by their scarcity in a place with such abundant light.   Florida is one of several states, mostly in the Southeast, that combine copious sunshine with extensive rules designed to block its use by homeowners to generate power.  

A Giant Floating Duck That Generates Solar Power—Because, Why Not?

A group of artists, scientists and engineers have proposed a novel solution to help Copenhagen's achieve its goal of becoming a carbon-neutral city: a 12-story-high solar energy farm in the shape of a duck. Energy Duck is the brainchild (brainduckling?) of the  Land Art Generator I nitiative  (LAGI), which designs public art installations that also function as utility-scale clean energy generators. So, why a duck? According to LAGI: The common eider duck resides in great numbers in Copenhagen; however, its breeding habitat is at risk from the effects of climate change. Energy Duck takes the form of the eider to act both as a solar collector and a buoyant energy storage device. Solar radiation is converted to electricity using low cost, off-the-shelf PV panels. Some of the solar electricity is stored by virtue of the difference in water levels inside and outside the duck. When stored energy needs to be delivered, the duck is flooded through one or more hydro turbines to generate electricity, which is transmitted to the national grid by the same route as the PV panel-generated electricity. Solar energy is later used to pump the water back out of the duck, and buoyancy brings it to the surface. The floating height of the duck indicates the relative cost of electricity as a function of citywide use: as demand peaks the duck sinks.  

Britain Is Solar-Energy Hot Spot

Britain, a land of cloudy skies and reliable rain, is fast becoming the hottest spot in Europe for many investors in solar energy. Germany is overcrowded with panels. A sudden end to subsidies killed Spanish solar. A sluggish economy is dragging on Italy. But the U.K. has benefited from a combination of stable subsidies since 2011, public support for solar, amenable planning authorities and creative finance. In 2010, there were under 100 megawatts of solar capacity in the U.K.—barely enough to power the homes of a modest town. Now, there is between 3.2 and 4 gigawatts. This year, market-research firm Solarbuzz projects that the U.K. will overtake Germany as Europe's largest installer of solar panels, putting in 6% of the world's new solar.

China Solar Projects Poised to Fuel Panel Price Rebound

The expected recovery in China, which accounts for more than 60 percent of global solar panel output, offers an early sign that manufacturers are succeeding in soaking up supply by building their own projects. The government’s push to promote developments closer to regions where electricity is needed most -- so-called distributed solar projects -- may also spur orders. Panel prices in China declined about 10 percent in the first six months of the year compared with the second half of last year, according to Bloomberg New Energy Finance. Higher tariffs imposed in the U.S. have had the opposite affect to what’s happened in China. Panel prices have increased about 15 percent since early June when the U.S. decided to apply preliminary duties on Chinese solar equipment imports, according to a global measure of panel prices. The U.S. Commerce Department acted again on July 25, proposing expanded penalties on some Chinese solar-energy imports in a victory for the U.S. unit of SolarWorld AG, which accused China of shifting production to Taiwan after it lost an earlier case.

China Poised For Significant Expansion In Wind Power Generation

China is the world’s largest producer of electricity, surpassing the United States in 2011, with demand increasing alongside its strong, sustained growth in GDP.  Electricity generation in China has increased 9.6% annually, from 2005 to 2013, reaching 5,425.1TWh of electricity.  Coal-fired plants currently make up over two-thirds of power generation, which is partly the result of an abundance of coal in China.  Despite this growth, the country expects demand to continue to increase at a rapid pace, reaching 7.295TWh of demand in 2020 and 11,595TWh in 2040.     However, the growth in electricity production from coal-fired plants has resulted in an increase in air pollution and general lack of efficiency.  China is now moving aggressively to curb pollution and increase the supply of renewable power.  The central government has prohibited new coal-fired plants to be built around Shanghai, Guangzhou and Beijing, which is currently in the midst of having all of its coal plants being converted to natural gas.  Its 12th Five Year Plan, running through 2015, targeted non-fossil fuel energy to account for 15% of total energy consumption.  One of the key industries expected to help meet these goals is wind power.  

SEIA: Future Unclear Despite WTO Ruling in China Solar Trade Case

WASHINGTON, D.C. – In a significant ruling handed down today, a panel of judges at the World Trade Organization (WTO) accused the United States of violating global trade rules when it imposed punitive import duties in 2012 on many Chinese products, including solar panels. After the decision was announced, Rhone Resch, president and CEO of the Solar Energy Industries Association (SEIA), issued the following statement:  "We are continuing to follow developments closely, but today's WTO decision is not expected to impact either the 2012 U.S. solar countervailing duty (CVD) order against China or any new CVD tied to the ongoing investigation until 2016, at the earliest. It's also important to remember that this decision is subject to an appeals process, which could take approximately 120 days. Assuming the decision is upheld on appeal, the United States would then have approximately one year to implement the decision. But even then, it's not clear whether the decision will result in any substantive modification of a solar CVD order against China."

Is Texas Souring On Wind Power?

Texas has more wind power generation than any other state, so it’s only fitting that Texas regulators are starting to ask some tough questions about wind power subsidies. The head of the state’s Public Utility Commission, Donna Nelson, is calling for a study to consider whether wind generators should start paying their share of transmission costs. Texas already invested $7 billion in high-capacity power lines that the state built to connect West Texas wind farms with the more populous cities in the east — such as Dallas and Houston. But wind power, as an intermittent resource, can create additional transmission costs, and those costs are borne by all the electricity customers in the deregulated market, which is about 85 percent of the state. Part of the study will determine the amount of the extra transmission costs and what, if any, remedy is needed, a PUC spokesman said. Wind power developers warn that making wind companies pay the same transmission rates as other generators will destroy Texas’ lead in wind power and undermine the economics of wind generation. Nelson, however, claims that giving wind companies a pass is no longer necessary because the industry has been around long enough to figure out its economics.

Intersolar North America: Exhibition opens doors

From PV Tech:  Intersolar North America opens its exhibition doors today off the back of a bumper year of PV installations in the US. With conference sessions kicking off in San Francisco on Monday, attention today will turn to the exhibition halls, where optimism among visitors is understandable despite warnings of complacency. At the official opening of Intersolar North America on Monday evening, Governor Jerry Brown stressed that while California had made great strides in improving its sustainability, there was still much work to be done with solar playing an important role in that future. “We have to invent not just gadgets, but keep our eye on the big goal. The big goal is to build a more equitable and just society…and that’s why solar is so important,” said Brown.    As a media partner AltEnergyMag.com will be covering Intersolar and bringing all the industry news and exciting new products to our eMagazine to help our readers make sense of the massive event.

India's Solar Power Dreams on Hold

India's plans for a major ramp-up in solar power are on hold after a proposal to impose anti-dumping duties on equipment from overseas has led developers to say proposed projects would become unprofitable. Industry officials say imports of solar equipment worth millions of dollars that were in the pipeline from U.S., China, Taiwan and Malaysia are now unlikely to come to India anytime soon. India had been planning to raise solar power generating capacity nearly tenfold by 2022 to help wean itself off heavy imports of oil and gas that contribute to a chronic trade deficit. The sector has been booming in recent months too, as the cost of imported solar equipment has dropped sharply. But the commerce ministry is now proposing duties on goods from overseas to protect local manufacturers from being overwhelmed by the cheaper imports. The finance ministry will take a final decision on the proposal by Aug. 22. Any tariff proposal is set to fuel tensions between India and U.S., with trade relations already at a flash-point as the World Trade Organization deliberates a India-U.S. dispute over a rule that mandates local sourcing for some government-backed solar projects.

Wind Power Service Market to Almost Double by 2020: Make

The market for servicing wind turbines will almost double by 2020 as capacity grows, the Danish advisory firm Make Consulting said.   Annual revenues from monitoring and repairing wind turbines may surge to more than $13 billion in 2020 from $7.1 billion last year, Aarhus, Denmark-based Make said today in a report. It projected that 300 gigawatts of capacity will be installed through 2020, doubling current generating capacity and boosting the needs for maintenance.   Turbine manufacturers including Vestas Wind Systems A/S (VWS) and Gamesa Corp. (GAM) Tecnologica SA are ramping up efforts to secure service contracts, which Vestas says yield higher margins than turbine sales and increase profitability. More than half of servicing worldwide is carried out by turbine manufacturers, Aaron Barr, a consultant at Make in Boston said in an e-mail.   Manufacturers “are attracted to the services market due to reliable and repeatable high margin revenue, primarily due to the growing fleet of serviceable wind turbines,” Barr said. “This focus is reinforced by uncertainty on new turbine sales orders and technical competitive advantages” that they have over independent service providers and the utilities that own the wind farms.
