Israel, a global cleantech powerhouse, is now attracting hundreds of millions of dollars in cleantech investment every year.

The country gets more from its soil, water, air, and sunlight than most other nations on earth.

Why has such a small country been able to position itself a world leader in cleantech?

The answer, I believe, is a combination of many factors: its history, attitude of the people, ingenuity, and challenges to survival.

According to my research, the following are major highlights of Israel’s cleantech leadership to date in 2010: (more…)

Sunny Milpitas, California is the newly announced home of SunPower’s first domestic manufacturing operations. Yep, you heard right. More green manufacturing jobs right here in the U.S.A. (In November, Chinese solar powerhouse Suntech announced that its first U.S. manufacturing facility would be located near Phoenix, Arizona).

SunPower’s  75-megawatt production line is expected to employ 100 by the end of the year, and spread the wealth around even more by sourcing equipment and materials from a host of other states throughout the United States. At the Vote Solar Initiative, we like to remind folks that manufacturing is only a fraction of solar’s overall job creation opportunity. In fact, about 75 percent of solar employment is related to system installation, jobs that are inherently local in the first place. Nevertheless, manufacturing is near and dear to most Americans, and this new production facility is tangible proof that the green economy has a real role to play in bringing those jobs back home — with the right policies, that is.

As was the case with Suntech’s Arizona selection, SunPower’s decision to locate manufacturing in California is a testament to the state’s market-building solar policies. And so it is appropriate that stalwart renewable energy supporter, Governor Arnold Schwarzenegger, joined in making the announcement. During the event, Schwarzenegger highlighted a few initiatives that have been so instrumental to the state’s new energy economy that we think they bear repeating: (more…)

U.S. investors have invested $129.4 million in a promising solar technology that uses plastic lenses to concentrate sunlight onto small but highly efficient solar cells.

The so-called multijunction cells, developed by California-based Amonix, generate more electricity than conventional photovoltaic panels and require fewer costly semiconducting materials, such as silicon.

The company has successfully tested the technology at small solar farms in Spain and the United States. (more…)

In California, low-income households often spend more money on electricity than more affluent residents and produce greenhouse gasses in the process.

But through the California Solar Initiative’s Single Family Affordable Solar Homes (SASH) program, and an Oakland-based nonprofit firm called GRID Alternatives, the state’s low-income homeowners finally have the change to reduce their monthly electricity bills and decrease electricity usage.

Longtime friends and engineers, Erica Mackie and Tim Sears, founded GRID during the 2001 energy crisis.  While developing renewable energy systems for the private sector, Sears and Mackie decided to try and make the technology available to low-income communities.  Their model became GRID Alternatives’ first Solar Affordable Housing Program.

Government subsidies that helped fuel Europe’s most successful solar markets continue to be slashed, raising concerns that the region’s burgeoning renewable sector will be unable to compete with China and the U.S., according to a report on Greenwire.

Germany, the world’s largest market for solar power, will cut the price paid for electricity from roof-mounted panels by 16 percent and electricity from larger solar power stations by 15 percent.

Analysts say the government simply underestimated how quickly the renewable sector would grow. From 2000 to 2008, the production of photovoltaic energy in Germany rose from 32 million kilowatt hours to 4.4 billion kilowatt hours. Government subsidies in Germany now cost nearly €1.5 billion annually. (more…)

Solar power is supposed to be clean and green, but what happens to the dirty ingredients involved to make and dispose of solar equipment?

Two years since the Washington Post first reported that a maker of polysilicon for solar panels was dumping toxic waste into Chinese soil, a U.S. nonprofit has ranked the “green” aspects of 25 photovoltaic module makers. The Silicon Valley Toxics Coalition launched the Solar Scorecard (PDF) on Tuesday.

Installations of solar modules rose by 42 percent in 2009, according to SolarBuzz. If this growth continues, rooftop modules that wear out within two to three decades threaten to add toxic bulk to landfills, just as yesterday’s computer monitors and cell phones have created unwieldly piles of consumer electronics waste.

“2010 will be a day of reckoning for solar projects that have been announced,” said Mark McLanahan, CEO at Renewable Ventures, a Fotowatio company.

Five hundred bankers and solar executives speculated about the promise and pitfalls of implementing solar power projects at the 2010 Solar Power Finance & Investment Summit in San Diego last week.

Permitting the Biggest Challenge

Permit approval and securing financing dominated the two-and-a-half day meeting as the greatest obstacles to completing projects.  A panel of venture capitalists agreed that in all cases, developing solar projects and technology consistently takes longer than expected.

According to Sven Strohband, partner with MDV-Mohr Davidow Ventures, this is because “materials science is hard, but not as hard as biology: We are trying to do something truly new, and solar investments require a lot of capital to go to market.”  (more…)

During the 2010 Solar Power Finance & Investment Summit in San Diego, a large crowd learned that Chinese companies have cash and interest in the US solar energy market, yet partnerships require patience and low risk.

To explore the opportunities, R. Thomas Hoffmann, Partner with Ballard Spahr, led a panel with three experts on Chinese solar investing. They were:

• Jimmy Chuang, is with GCL Solar, the largest polysilicon producer in Asia and the largest solar developer in China.  GCL has access to $4.5 billion.

• K. Scott Son, Vice President of Project Finance at Suntech, the largest producer of silicon PV in the world (nearly $2 billion in revenue in 2008).

• Sha Wang, Principal at Cybernaut Investment, a family company with US and Chinese roots and a $500 million solar investment fund.

California recently approved the decision of a state-wide solar heating program consisting of almost $360 million financial incentives and market development funding by 2018. This initiative will soon be followed by rest of the country that lagged behind the world in installing solar thermal systems.

Global statistics show that the solar thermal industry is taking large steps in fulfilling heating and cooling demand in the world. Most of the countries around the world have adopted incentive programs for both solar water heating and space heating. Whereas in some countries, solar thermal systems have been widely utilized for so many years even without incentives.

The most important decision criteria for a household to install a solar thermal system is basically the payback times of their investment. The main driving factors of the investment payback time are the total cost of the systems and the cost of alternatives heating systems. (more…)

The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm both water and space.

China, for example, is now home to 27 million rooftop solar water heaters. With nearly 4,000 Chinese companies manufacturing these devices, this relatively simple low-cost technology has leapfrogged into villages that do not yet have electricity. For as little as $200, villagers can have a rooftop solar collector installed and take their first hot shower.

This technology is sweeping China like wildfire, already approaching market saturation in some communities. Beijing plans to boost the current 114 million square meters of rooftop solar collectors for heating water to 300 million by 2020. (more…)
