A discussion covering the geothermal context, power generation, ground source heat pumps and geothermal's potential for the future.
It's like having a blueprint to build a house, rather than just buying appliances, walls, and other parts. It is important to set out with a plan for what you want to end up with.
One half of the VOTO is a fuel cell and the second half is a handle which has a light, cell phone adapter and nickel-metal hydride battery to store energy.
It seems that we've proven ourselves exceptionally able in arguing with one another. The time for that has passed. Nature will act if we don't.
Liquid fuels derived from plant biomass are one of the best alternatives if an inexpensive means of commercial production can be found. Major research efforts are focusing on fatty acids, which are the energy-rich molecules in living cells that have been dubbed nature's petroleum.

Permanent magnet alternators are very compact compared to asynchronous generators and allow simplified mechanical integration thanks to being direct-driving by the rotor.
SunPower Corp. (SPWR), the second-largest U.S. solar-panel maker, is testing power-storage systems in three countries to complement its residential systems, its chief executive officer said. The company is evaluating batteries in Germany, Australia and California and expects to have a product to sell to customers within the next couple of years, Chief Executive Officer Tom Wernersaid today in an interview at Bloomberg’s New York headquarters. Adding batteries to residential solar systems would let people power their homes at night with electricity generated during the day, decreasing demand for energy from the grid and creating a threat to utilities’ revenue, Werner said. California will require utilities to use storage by 2020 and Germany introduced incentives in May to promote wider use of the technology. “In the near term, we’re driven by policy,” he said. “In the long-term it’s economics.” The company, based in San Jose, California, gets at least 25 percent of its revenue from photovoltaic panels that end up on consumers’ rooftops. SolarCity Corp. (SCTY), which provides rooftop solar systems, began offering lithium-ion battery storage units made by Tesla Motors Inc. (TSLA) last week.
GTM Research and the Solar Energy Industries Association® (SEIA®) today released U.S. Solar Market Insight: 3rd Quarter 2013, the definitive analysis of solar power markets in the U.S., with strategic state-specific data for 28 U.S. states and the District of Columbia. The U.S. installed 930 megawatts (MW) of photovoltaics (PV) in Q3 2013, up 20 percent over Q2 2013 and 35 percent over Q3 2012. This represents the second largest quarter in the history of the U.S. solar market and the largest quarter ever for residential PV installations. Even more importantly, 2013 is likely to be the first time in more than 15 years that the U.S. installs more solar capacity than world leader Germany, according to GTM Research forecasts. "Without a doubt, 2013 will go down as a record-shattering year for the U.S. solar industry," said Rhone Resch, SEIA president and CEO. "We've now joined Germany, China and Japan as worldwide leaders when it comes to the installation of new solar capacity. This unprecedented growth is helping to create thousands of American jobs, save money for U.S. consumers, and reduce pollution nationwide. When it comes to preparing for America's future, clean, dependable and affordable solar energy has become the ‘Little Engine That Could,' defying expectations and powering economic growth – and, frankly, we're just scratching the surface of our industry's enormous potential."
In the last few years peer to peer lending and crowdfunding have blossomed. While it's great to crowdfund the latest cool product that lets you cut down on using plastic or turns your regular bike into e-bike, it's infinitely cooler tocrowdfund the shift to renewable energy. Mosaic calls itself an online marketplace for solar. Basically the company provides debt financing to solar projects and lets individual and institutional investors buy shares in a project until it is funded. When projects are complete, the company sells power to a solar customer via a long-term contract, and shares returns of approximately 4.4 - 6.36% with its investors. Investment capital is paid back along with the interest over a 5 - 10 year period. Now Mosaic wants to take that concept to larger number of potential investors with a new incentive - the company will give new investors $25 once they make their first investment (minimum investments are $25). Once a new user sets up a Mosaic account and finds a qualified project to invest in, Mosaic will add $25 to the amount invested.
SolarCity—a company that’s grown quickly by installing solar panels for free and charging customers for the solar power—announced a new business that will extend that model to providing batteries for free, too. SolarCity is a rare success story for investors in clean technology, and its business model has sped the adoption of solar panels. The batteries could help businesses lower their utility bills by reducing the amount of power they draw from the grid. They could also help address solar power’s intermittency, which could prevent it from becoming a significant source of electricity. The batteries are being supplied by Tesla Motors, whose CEO, Elon Musk, is SolarCity’s chairman. Other solar companies have failed in recent years. But SolarCity’s business model has helped it grow quickly. It had a successful IPO a year ago, and its stock price has risen from its IPO price of $8 to over $50 today. CEO Lyndon Rive says that eight years from now, the company might not be able to continue selling solar panel systems unless it packages them with batteries, because of the strain on the grid that solar power can cause. “It could be that, without storage, you won’t be able to connect solar systems to the grid,” he says.
Hitachi, Ltd. announced that it has developed an all-in one, container-type energy storage system as a core energy product for ensuring the stable use of distributed renewable energy such as wind and solar power, while maintaining the power supply-demand balance. This energy storage system fuses Hitachi's electricity grid control technologies built up in the Hitachi Group and Hitachi Chemical Co., Ltd.'s battery-related expertise and will be offered as a packaged system. In the beginning of 2014, Hitachi plans to begin a demonstration test of this energy storage system in North America. Plans call for Hitachi to reflect the results of this testing in a commercial product after verifying the commercial viability and performance of the system in the electricity trading market, or the so-called ancillary market*2 connected with maintaining the electricity supply-demand balance. Furthermore, Hitachi will examine whether to promote the system, to be named "CrystEna" (Crystal+Energy), as one of its solution businesses for expanding the transmission & distribution business in the global market.
European Union countries approved an agreement with China to curb imports of Chinese solar panels, ending the EU’s biggest commercial dispute of its kind. EU governments endorsed an accord struck by their trade chief and China in July that sets a minimum price and a volume limit on European imports of Chinese solar panels until the end of 2015. Chinese manufacturers that take part will be spared EU tariffs meant to counter alleged below-cost sales, a practice known as dumping, and subsidies. The verdict seeks to balance demands by European producers such as Solarworld AG (SWV)for trade protection and opposition by China, some EU governments and Europe’s importers to levies on the renewable-energy technology. The two-year duration of the measures is less than half as long as the normal five-year period for EU anti-dumping and anti-subsidy protection. European solar-panel manufacturers suffered “material injury” as a result of dumping by Chinese exporters and trade-distorting government aid to them, while trade protection must also take account of “the cost for other economic operators,” the 28-nation bloc said today in Brussels. The decision wraps up two inquiries begun more than a year ago and will take effect after being published in the EU’s Official Journal by Dec. 6.
The rapid growth of distributed energy resources (DER), a non-transmission alternative, is raising concerns over the viability and necessity of new transmission lines.
All five of the major solar thermal projects—including Solana and Ivanpah—that are scheduled to come on line in 2013 and 2014 were awarded loans through the U.S. Department of Energy's Loan Guarantee Program.
