Shrink Nanotechnologies is one of several companies that is using bioplastics to find a new way of making devices that will minimize the use of increasingly-scarce rare metals.

The company’s OptiSol Solar Concentrator is billed as a nanotechnology-based plastic solar concentrator and solar film. Traditional silicon solar cells absorb only a small fraction of the total incident solar radiation potential, with a majority of the light either reflected or converted to thermal energy.

China is the world’s largest manufacturer of solar photovoltaic panels, providing roughly 40 percent of the global market share in 2008. China’s domestic solar market is on the cusp of a boom thanks to new solar incentives announced this year cutting the cost of purchase and installation by as much as half.

With over 150 attendees, including international senior executives, top-level Chinese government officials, industry experts and leading production and technology directors, the China Solar Energy Technology and Investment Congress organized by Noppen in close co-organization with Huhhot Municipal Government took place on 10-11 December in Huhhot, Inner Mongolia, China. The focus of the event was how to drive down the cost per installed watt and the future growth of the solar energy market in China.

Ormat Technologies, Inc., announced today that its Israeli subsidiary, Ormat Systems Ltd., has signed a Joint Venture Agreement (“JVA”) with Sunday Energy Ltd. (“Sunday”), an Israeli solar integration company, to construct and operate solar-photovoltaic (“PV”) energy systems in Israel with a total capacity of 36 megawatts (MW).

Under the JVA, Sunday will contribute the rights to all of its property and roofs required to develop solar energy systems above 1 MW to special purpose entities (“SPEs”). Ormat will own 70% of each SPE and will also have control of it. Under the terms of the agreement, Ormat and Sunday will act, jointly, as the engineering, procurement and construction (“EPC”) contractor and the operator of each project in accordance with each company share in the SPEs .

Imperial County, tucked away in the southeastern corner of California, has long suffered from perennial unemployment rates exceeding 20 percent.

Yet Imperial County is also home to the “crown jewel” of all geothermal steam resources in the U.S., making it a prime spot to showcase how renewable energy can help spur the new green economy so enthusiastically touted by the Obama Administration.

Late December, the California Public Utilities Commission (CPUC) approved the construction of the $1.9 billion Sunrise PowerLink transmission line, which could send clean electricity from Imperial County to San Diego. However, the Center for Biological Diversity (CBD) petitioned the California Supreme Court last January to review this decision, citing San Diego Gas & Electric’s (SDG&E) refusal to guarantee that the transmission project would be reserved exclusively for renewable energy resources.

Solar thermal energy, which is the oldest way of tapping power from the sun, has been used for years in heating applications for households. Although its counterpart solar photovoltaic seems to be getting more attraction, according to European Solar Thermal Industry Federation (ESTIF),  solar thermal energy industry in Europe has grown over 60% in 2008.

In a recent interview broadcasted by RenewableEnergyWorld.Com,  Olivier Drücke, president of ESTIF, mentions that the solar thermal potential in Europe can meet 15% of heating and cooling demand in 2030 and up to 50% in 2050. That is particularly significant given that heating and cooling demand represents 50% of the final energy consumption in Europe (with the remaining 20% for electricity generation and 30% for transportation).
