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 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, 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.
As PV plants come out of warranty from the installer, an understanding of what needs repair, when, and how to do it is just as important as what equipment was selected and how it was installed.
Regenedyne has invented a magnetic levitation system, that when combined with the advanced aeronautics, eliminates the wobble issue and allows for a smooth, near frictionless, rotation.
Here are some of the more popular articles so far this year --- a wide range of alternative energy topics.
The PV pioneers and solar veterans made the future possible, but we couldn't imagine what it would look like. The young now own it, and they have no doubts about where it is going, and what they have to do to get it there.
Sun tracking is accomplished through azimuth and elevation (screw jack) drives that require a high degree of accuracy and durability.
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 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.
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."

The three products we offer are the PowerChip, a silicon based fuel cell product targeted for defense and commercial customers, the second product is the BuzzBar Suite that is targeted at consumers for cell phone and tablet charging, and the final product is the Formira product, which is an air based fuel cell technology that generates hydrogen for formic acid and that can be used for larger power ranges.
Biomass is an important material for the sustainable source of energy. It can generate solid, liquid and gaseous products under different thermochemical conversion technologies. In this study, Melia dubia - a fastest growing energy crop was subjected to pyrolysis. Two products namely, biooil and char were produced and their characteristics were analyzed.
The equipment's power requirements can be met by the fuel cell system for 17 to 19 days without being refueled, and that window could be pushed to 21 days if a storm prevented access during the normal refueling window.
