Magnetic Energy

Is a perpetual magnetic generator impossible? Maybe, but there have been several patents issued on this theory and as the cost of energy keeps rising, more scientists will be searching for ways to make a working practical perpetual magnetic generator.

Momentum / Inertial Energy

Where M/I shines is in the delivery of vast amounts of energy with no fuel cost. When compared to other non-fuel sources, [solar, wind and hydro-electric] a dense 1 mile M/I installation will generate, during rush hour, as much energy as a 3 square mile photovoltaic installation on a very sunny day.

Solar-panel prices to rise due to anti-dumping tax

MUNICH--U.S. solar panel prices are set to rise in the short term due to last month's imposition by the Obama administration of 31% tariffs on some Chinese panels, two of China's largest solar companies said Tuesday. The tariffs, however, are unlikely to significantly hit Chinese companies that have diverse global supply chains and production capacities outside China, said executives of Suntech Power Holdings Co., the world's largest manufacturer of photovoltaic solar panels, and JinkoSolar Holding Co. Ltd. The comments come after the U.S. government last month imposed 31% tariffs on some solar panels produced in China alleging they had been dumped, or sold below cost. "We will see some price increases in the short-term" for solar panels in the U.S., JinkoSolar's Marketing Director Isabelle Christensen said on the sidelines of the Intersolar industry exhibition in Munich.

National labs: Wind energy costs at or heading to all-time lows

Most studies predict the cost of wind energy will continue to fall through at least 2030, said national laboratory staffers in a new report . The report, "The Past and Future Cost of Wind Energy," released June 6, is a collaboration among workers from the Lawrence Berkeley National Laboratory and the National Renewable Energy Laboratory, with assistance from European researchers. The crux of the report is that while future trends, drivers and constraints are difficult to predict, the cost of wind-generated electricity will probably continue to decrease in the coming decades. Onshore wind's levelized cost of energy, or LCOE, fell by a factor of more than three between 1980 and 2000, the researchers said. "However, beginning in about 2003 and continuing through the latter half of the past decade, wind power capital costs increased — driven by rising commodity and raw materials prices, increased labor costs, improved manufacturer profitability, and turbine upscaling — thus pushing wind's LCOE upward in spite of continued performance improvements," they said.

Wind turbine manufacturers say U.S. market will grow in time

The wind energy market in the U.S. will stay alive with or without an extension of the Production Tax Credit (PTC), say executives from eight of the largest wind turbine manufacturers with a U.S. presence. During a June 6 session focused on large wind turbines during WindPower 2012, executives from Gamesa, GE (NYSE: GE), Goldwind, Mitsubishi Power Systems, Nordex, Siemens (NYSE: SI), Suzlon and Vestas expressed that they view the U.S. wind market as a strong one. The U.S., currently the No. 2 wind market in the world, installed 6,810 MW in 2011. This year is expected to be a record-breaking year for installations, as the expiration of the PTC requires developers to complete projects by year end. All eight executives agreed that 2012 will likely see anywhere from 9 to 12 GW of wind power installations. Beyond 2012, the market is likely to slow, but the panelists said that won’t keep their companies from staying in the U.S. The wind energy market could be down 80 percent next year, said Duncan Koerbel, interim CEO of Suzlon. “But Suzlon is in this for the longest of the long hauls. If you’re going to be in wind, you have to be in North America.”

Live from #WP12: Industry, officials voice support for extension of federal wind energy tax credit

Kicking off the American Wind Energy Association‘s convention center-sized pitch for an extension of the production tax credit, AWEA CEO Denise Bode said Congress needs to act now to prevent further damage to the industry. “We are very concerned new wind projects are being shelved,” Bode said opening AWEA’s annual WINDPOWER conference in Atlanta on Monday. “The bleeding has to stop now.” Bode said she remains optimistic that the production tax credit will be extended before its scheduled expiration at the end of this year, but that the “political logjam” continues to hold up the policy despite bipartisan support.

Thin-Film Solar Panel Maker Konarka Files for Bankruptcy

Konarka Technologies Inc., the thin-film solar panel manufacturer backed by Chevron Corp. (CVX) (CVX) , Draper Fisher Jurvetson and New Enterprise Associates Inc., filed for bankruptcy in Massachusetts. “Konarka has been unable to obtain additional financing, and given its current financial condition, it is unable to continue operations,” Howard Berke, chief executive officer of the Lowell, Massachusetts-based company, said yesterday in a statement. Konarka listed $100,000 to $500,000 in assets and $10 million to $50 million in debt in its Chapter 7 filing yesterday in U.S. Bankruptcy Court in Worcester, Massachusetts. Konarka NB Holdings LLC, in a separate filing, listed $1 million to $10 million in assets and as much as $50,000 in debt.

Biofuels for the future

We still need a lot more research into different biofuels to see which source will be low cost and environmentally safe. Using a weed, pond scum, municipal waste and manure are future possibilities of biofuels that help, rather than damage our food sources and the environment.

Short-Term Politics Stifles Pentagon's Green Energy Ambitions

Undermining the Pentagon's alternative energy plans can only be political, and specifically a Republican attempt to undermine the largely energy-focused campaign of President Barack Obama. After the elections, it should regain lost traction the next time it comes around for a vote.

The Renewable Energy Market Climate

Regulation continues to be a key influencer and driver of the overall solar marketplace. Despite the advantages of solar as a virtually free energy, the market relies on regulation in order to deliver desired returns on investment.

The Army's $7 Billion Renewable Energy Contracts

The military services want the private sector to design, build, own and operate the alternative energy generation capacity and sell the energy to the military services.

New Guidelines Encourage Biodiesel Production in Texas

The Texas Commission on Environmental Quality (TCEQ) has introduced new state guidelines which allow for biodiesel to be blended at any ratio into any compliant fuel.

Just How Green is Google

In the realm of clean energy and the US drive to reduce dependency on foreign fuel imports, Google and other IT giants could wield a significant amount of influence, both on the public and on policy.

Potentially incorrect beliefs currently prevalent in the Solar Energy Industry

It is entirely technically reasonable to amortize the financing of a well engineered solar array over 30-40 years, not just 20.
