Alternative Clean Energy Roundup: 18 August 2013

Green jobs outstripping others in US
07 August 2013 - America's emerging clean energy economy produced new jobs at more than twice the rate of more traditional industries in the years leading up to the economic downturn, a new study released today claimed.

The report by the Pew Charitable Trusts provides the first hard evidence of jobs created by the rising demand for environmentally friendly services, and in the new clean energy sectors like wind and solar.

It said such jobs grew at a rate of 9.1% from 1998-2007, easily outstripping job growth in traditional areas of the economy, which was 3.7%. read more>>>

Age Old Perovskite Mineral Offers Promise of Dirt Cheap Solar Power
08/15/13 - Researchers have discovered that a mineral known to science for over a century has great potential for solar power applications. Perovskite, which is an abundant mineral first discovered in the Ural Mountains of Russia in the mid 19th century, is said to be very efficient at absorbing light and uses less material to capture the same amount of energy when compared to conventional solar absorbers.

At present there is a duality between cheap and efficient solar power. The most common form of solar cells are silicon based and cost as little as 75 cents per watt. While Gallium arsenide has the highest recorded efficiency of 44%, the metal’s cost can be as high as $1200 for one kilogram. read more>>>

China Sunergy Launches Super Black Module
Aug 8, 2013 - China Sunergy Co., Ltd. (NASDAQ: CSUN) ("China Sunergy" or "the Company"), a specialized solar cell and module manufacturer, today announced that the Company has introduced the Super Black module following an initial custom order for a 60KW rooftop project in Hawaii. Delivery is expected in mid-August.

The Super Black module offers a pure black appearance for the entire panel including welding strips, making the module well suited for high-end rooftop projects and integrated constructions. read more>>>

University of Colorado develops new technique for producing hydrogen fuel
06 August 2013 - Sunlight could be used to split water into hydrogen and oxygen says research team

A team of researchers from the University of Colorado at Boulder (CU-Boulder) has developed a radical new technique for producing hydrogen fuel. The procedure involves using sunlight to split water into its constituent hydrogen and oxygen components. It would involve a solar thermal system in which sunlight is concentrated by a vast array of mirrors into a single point focused on top of a tower up to several hundred feet in height. read more>>>

The Best States for Residential Solar Energy
17 August 2013 - With the horizon for solar energy looking brighter and brighter, how do you know if switching to solar is right for your home?

The cost of manufacturing photovoltaic (PV) panels continues to decrease. In addition, many states offer generous tax incentives, grants, and subsidies for homeowners combined with a 30% federal tax credit. Solar energy is increasingly accessible for American households especially with the expansion of solar leasing now into 15 states and net metering policies in 43 states. read more>>>

Balance of Systems components costs in USA still higher than Germany
Aug. 7, 2013 - At a recent PV Insider webinar on reducing costs in the balance of systems in the USA it was revealed that the world’s second largest utility-scale PV market continues to suffer from higher prices for key components compared to Germany, in spite of much larger growth in utility-scale PV. These higher prices are seriously hampering PV’s competitiveness against other fuels and may be a major stumbling block to making PV more competitive.

According to data collected by Paula Mints at SPV Market Research, the costs for wiring and hardware are almost double those of Germany with an average of $0.47 (in the USA) and 0.43 ( in Germany) cost for inverters in a plant whose profit falls within a higher band. read more>>>

Siemens drives innovative use of regenerative energy sources
Aug. 7, 2013 - Successful implementation of modular power electronics for feeding into the grid

Together with the Technical University of Dresden and the University of the Federal Armed Forces in Munich, Siemens has carried out research work into a highly efficient and robust medium-voltage converter for feeding electrical energy into power supply grids. The insights gained were successfully implemented within the scope of the research project funded by Germany‘s Federal Ministry of Research and Education (BMBF) on the basis of a demonstrator, and will be incorporated into the next generation of products. read more>>>

Distributed wind increasingly powerful
August 9, 2013 - More Americans are installing wind turbines near their homes, farms and businesses to generate their own energy, according to research from the Department of Energy and Pacific Northwest National Laboratory which indicates strong growth in the U.S. distributed wind energy market.

Compared to traditional, centralized power plants, distributed wind energy installations directly supply power to the local grid near homes, farms, businesses and communities, helping to improve grid reliability and efficiency. read more>>>

Helping countries reduce agricultural greenhouse gas emissions
Aug. 6, 2013 - New FAO guidance on how agricultural development planning can help tackle causes of global warming

Rome -- With the consequences of climate change for the world's food production systems becoming increasingly clear, more needs to be done to capitalize on agriculture's potential to mitigate global warming, says a new FAO guidance document published today.

Agriculture is directly responsible for over 10 percent of all human-caused greenhouse gas (GHG) emissions, FAO figures show. read more>>>

Green investment will deliver sustainable growth in South Africa, says report
August 8th, 2013 - Green investment in South Africa could inspire growth and create jobs, according to a new study.

The report claims that investment in a low-carbon and resource efficient economy could create 170,000 jobs in the country, increase crop yields by almost a quarter and provide greater water availability.

It suggests that with greater sustainability across the board, South Africa would see more benefits that it would with a business as usual approach. Maintaining economic growth while lowering emissions of greenhouse gases would also cause less environmental damage. read more>>>
