Innovative Places to Install Solar Plants

India builds solar plants atop canals to save on land, water
January 16, 2015 - As India moves to ramp up investment in solar power, it is exploring innovative places to install solar plants, including across the top of canals.

Last weekend, U.N. Secretary General Ban Ki-moon inaugurated a new "canal-top" solar energy plant in Vadodara district in India's western state of Gujarat.

"I saw more than glittering panels – I saw the future of India and the future of our world," said Ban. "I saw India's bright creativity, ingenuity and cutting-edge technology."

Experts identify two major advantages in building solar plants atop canals: efficient and cheap land use, and reduced water evaporation from the channels underneath. read more>>>

Broke World's Solar Power Efficiency Record Last Month

Australia’s rising solar power ‘revolution’
January 13, 2015 - Australian researchers broke the world's solar power efficiency record last month with their design of a novel commercial energy system, raising hopes the fossil-fuel dominated country may someday switch off its reliance on coal.

A team at the University of New South Wales led by professor Martin Green worked with a local company to create a highly efficient solar energy system that uses mirrors to concentrate sunlight onto a central solar panel to generate electricity.

The method is known as concentrator photovoltaics (CPV), and the result is a system with an efficiency of 40 percent, meaning 40 percent of the sunlight hitting the solar panels is converted into energy — the highest such level ever achieved.

Most important, the design uses readily available materials, which makes putting the system into operation easier and cheaper than trying to commercialize more experimental designs.

Green, who is also the director for the Australian Center for Advanced Photovoltaics, has a history of this kind of innovation. In 2011 he and his team built a solar cell that operated with 19.3 percent efficiency, edging out the previous record holder's 18.9 percent efficiency.

Sun Shines, Energy, on Pakistan

Sun Shines on Union Between Solar Power and Electric Grid in Pakistan
January 6, 2015 - Amid a worsening energy crisis, Pakistan has approved the use of grid-connected solar energy, rooftop solar installations and mortgage financing for home solar panels to boost uptake of clean energy in the country.

The government has also reversed course and eliminated a 32.5 percent tax imposed on imported solar equipment in the country's 2014-2015 budget. The reversal aims to bring down the cost of installing solar panels.

The approval of net-metering – which allows solar panel purchasers to sell power they produce to the national grid - is a major breakthrough that could spur use of solar energy and help Pakistan's government cut power shortages in the long run, said Asjad Imtiaz Ali, chief executive officer of the Alternative Energy Development Board, a public organization.

"The initiative will help scale up demand for solar energy across Pakistan,” he said, “and we hope the increased demand will also result in sufficient decreases in the price of solar equipment.” read more>>>

Utilities Not Happy the Sun Shines Bright on Solar Energy

Instead of leading in the development, of Alternatives, starting back over some forty years ago as we once again started developing another huge industry, something we had done over and over in many area's, they continue joining with the special interests in fighting to block advancing forward!! We now don't have the innovative trades with ever growing experience as at the same time we were shipping ours to others with little to no regulations and much much cheaper labor, not cheaper consumer products, who now have the experiences and innovative skilled trades needed and are advancing!!

Utilities Fight For Revenue Lost To Solar Power
January 03, 2015 - Solar energy had a banner year in 2014. As more and more U.S. households make their own electricity with solar panels, they're paying less to electric utilities, and that's making the utilities a little nervous. In some states, those companies are fighting back. Lauren Sommer of member station KQED and Dan Boyce of member station KUNC tell us how sunny California and Colorado are handling the rise of solar.

DAN BOYCE, BYLINE: There's a quiet war going on, a slow simmering battle between electric utilities and solar companies.

LAUREN SOMMER, BYLINE: You probably haven't noticed this clash because it's happening one house at a time. read more>>>

NC Re-Evaluates the Rules for Solar Energy

Year-End Decision Holds Big Impact For NC Solar In 2015
January 2, 2015 - North Carolina energy regulators quietly released one of their most significant, long-awaited decisions of 2014, just as the year was ending. The state Utilities Commission had spent nearly the entire year re-evaluating the rules for solar energy. On Wednesday, the commission decided to leave substantially intact the rules which have underlied a solar energy boom in North Carolina.

The rules essentially required utilities to buy the power from small solar farms, at a set price, for up to 15 years. So, solar developers knew the price they would get for their product and how long they would get that price.

It’s a more generous deal than in most states, and North Carolina has become the fourth-largest producer of solar power in the U.S., largely due to small solar farms using these contracts. read & listen to more>>>

The Children’s Climate Crusade

Full Show: The Children’s Climate Crusade
January 1, 2015 - The very agencies created to protect our environment have been hijacked by the polluting industries they were meant to regulate. It may just turn out that the judicial system, our children and their children will save us from ourselves.

The new legal framework for this crusade against global warming is called atmospheric trust litigation. It takes the fate of the Earth into the courts, arguing that the planet’s atmosphere – its air, water, land, plants and animals — are the responsibility of government, held in its trust to insure the survival of all generations to come. It’s the strategy being used by Bill’s recent guest, Kelsey Juliana, a co-plaintiff in a major lawsuit spearheaded by Our Children’s Trust, that could force the state of Oregon to take a more aggressive stance against the carbon emissions. read more>>>

'Solar Tulips'

Aora’s solar tulips start shining in Ethiopia, without water!
Investments in solar energy innovations are not dead! Remember those weird and wonderful solar energy harvesting tulips planted in Israel and Spain? Seen miles away the sky-high tulips have found a new commercial home – in Ethiopia, the company announced last week in a press statement.

We’ve covered Aora over the years and thought possibly that this CSP, or concentrated solar thermal power innovation didn’t grow. We were wrong.

The Ethiopian Government, looking for resilient off-grid systems, is now piloting Aora’s system for sustainable development.

Aora’s tulips collect solar energy from 50 small mirrors and then focus the energy to heat oil and air, creating pressure to drive turbines in the tulips. The turbines create electricity. The solution runs without steam and water, important for off grid locations where there is no water. read more>>>
