As Congress wrestles with national energy policies and gubernatorial candidates tout their plans here, New Jersey officials say the state deserves credit as a leader in promoting solar power.
In just a few years of coordinated efforts, New Jersey has gone from a non-factor to number two among the states in solar installations connected to the power grid. While far behind California, New Jersey currently generates about twice as many solar kilowatt hours as number three Colorado.
While applauding the gains, many in the industry also say the state, like the nation, has fallen well short of performance goals. New Jersey rose to the top of solar charts in a period when there was little competition from other states.
Now, as the federal government begins to pay attention to renewable energy, New Jersey is in the midst of a challenging transition away from an easy to understand program, which gave rebates to install solar power cells.
The new program shifts the focus away from consumers to utility companies and investors by creating a marketplace for renewable energy credits. The concept has its supporters, though many are more hopeful than confident.
Still, at a time when solar businesses believe the technology is on the verge of a belated boom in the United States, recent New Jersey statistics wowed some attendees at a recent industry conference in Philadelphia.
“Making this even more remarkable is that in 2001 New Jersey had only six” solar cell installations connected to the power grid, compared to more than 4,000 today, wrote Bob Haavind of Photovoltaics World.

PowerSat Corporation (www.powersat.com), a pioneer in safe and reliable energy generation from space, today announced the filing of U.S. Provisional Patent No. 61/177,565 or “SPACE-BASED POWER SYSTEMS AND METHODS.” The patent includes two technologies, BrightStar and Solar Powered Orbital Transfer (SPOT), which enable the reduction of launch and operation costs by roughly $1 billion for a 2,500 megawatt (MW) power station.
“This patent filing is a watershed moment not only for PowerSat but for a renewables industry that, until now, could neither compete economically nor generate power at the base load scale of oil or coal,” said PowerSat CEO William Maness. “Today, the convergence of technology and energy demand, combined with the political will to wean us off of fossil fuels, enables space solar power (SSP) to fill a widening clean energy supply gap.”
SSP is a clean, viable solution to our world’s growing energy problems. Not limited by weather or geography, SSP solves the intermittency problems of earth-based renewables by providing a reliable and flexible energy source that is available 24/7. The underlying technology components are proven and systems will be deployable within a decade. Solar energy is captured via solar power satellites (known as powersats) and transmitted wirelessly to receiving stations at various points around the globe. Thousands of megawatts can be harnessed and shifted between receiving stations thousands of miles from each other—all in a matter of seconds.
PowerSat Corporation’s first patented technology, BrightStar, allows individual powersats to form a wireless power transmission beam without being physically connected to each other. This “electronic coupling,” conceptually similar to cloud computing, effectively eliminates the need to handle large (gigawatt) levels of power in a single spacecraft. Because of BrightStar, one transmission beam may now come from hundreds of smaller powersats. Another advantage of Brightstar is increased reliability. If any of the individual component satellites fail they can be easily replaced without significantly affecting the performance of the system, thus establishing much greater reliability.
The other technology being patented by PowerSat, Solar Power Orbital Transfer (SPOT) propels a spacecraft to an optimal, Geosynchronous Earth Orbit (GEO) using electronic thrusters that are powered by the same solar array that is eventually used for wireless power transmission. Until now, all satellites have had to use chemical propulsion or a chemically fueled “space tug” to move from Low Earth Orbit (LEO), which is 300-1,000 miles in altitude to GEO, which is 22,236 miles in altitude.
SPOT technology also decreases the weight of a powersat by 67%, dramatically reducing launch costs, and enabling PowerSat modules to fly on rockets to LEO, deploy their solar powered electronic thrusters and then fly themselves out to GEO. GEO, the orbit for most communications satellites, is optimal because it allows a powersat to harvest the sun’s energy continuously.

The first impression of anyone discussing the future of Sri Lanka’s energy landscape with retired Additional General Manager of the Ceylon Electricity Board (CEB), Kanagalingam Gnanalingam, must undoubtedly be… he is steadfast in his convictions that the large-scale adoption of solar energy is the only way to achieve a Sri Lanka free from its dependence on fossil fuels.
Currently, an independent consultant volunteering for organisations focused on renewable energy issues, particularly in the area of solar energy utilisation programmes, Mr. Gnanalingam first started researching solar energy in 1970 while at the University of Ceylon, Peradeniya. He continues his passion for all things solar to this day, sometimes spending as much as 15 hours a day on his research since retiring from CEB (aged 55 years) and migrating to Canada in 2001.
Considering his fascination with solar energy, it should come as no surprise that Mr. Gnanalingam’s greatest influence was Sri Lankan solar energy pioneer, and his former teacher, Prof. J.C.V. Chinnappa, then Professor of Mechanical Engineering at the University of Ceylon, Peradeniya, who now serves as an Advisor on Solar Energy to the Australian Government. While a part of Prof. Chinnappa’s team, Mr. Gnanalingam and others were credited with designing the first solar refrigerator working solely on solar energy as well as designing, constructing and testing a pressurised solar water heater in 1971.

“The Sun,” said Jalal al-Din Rumi, one of the world’s greatest poets, “must come.” And the Arab world, which was an engine for centuries of innovation in science, philosophy and the arts, is now poised to become a leader in solar technology.
Though reported to have 8.5% of the world’s oil reserves and 3.3% of the world’s gas reserves, Abu Dhabi has launched a fund worth more than US $10 billion to find advanced renewable energy technology solutions to climate change.
Solar energy is also set to power another major Abu Dhabi project — Masdar City. The ultra modern city, due to be completed by 2015, aims to be the first zero-carbon emission and car-free city in the world, housing 50,000 inhabitants and 1,500 companies.
Now Masdar PV, a company belonging to the Abu Dhabi Future Energy Company, a state-owned vehicle for renewable energy investment owned by the UAE, has announced plans to produce up to 280 MW of thin-film PV a year in Eastern Germany in partnership with Colexon Energy, a Hamburg-based company.
Under the deal, two facilities to manufacture large-scale PV modules, 5.7 square meters in size, are to be built between 2009 and 2013. One factory is to be located in Erfurt in Thuringia; the other in Abu Dhabi.
