The Pacific Northwest just finished four days of triple digit temperatures, which put the heat on renewable energy sources to keep up with demand. Just as records were being set for power consumption, wind power generation slowed due to the calm air from the locked-in high pressure system.
The extreme weather highlights the reality that wind — and to a lesser extent hydropower — may not be a panacea for power production.
Southern Washington and the Portland metro area had a record breaking streak of warmth that pushed energy demand to record highs, but the high pressure system also featured calm breezes. The local utility Bonneville Power Administration (BPA) had to quickly balance the reduction in wind power with increases in hydropower.

The goal is to enable power generation from low-temperature geothermal resources at an economical cost. In addition to being a clean energy source without any greenhouse gas emissions, geothermal is also a steady and dependable source of power.
A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) are testing a new innovative approach to safely and economically extract and convert heat from vast untapped geothermal resources.

The Turkish Statistical Institute announced that the Turkish economy shrank 13.8% and that the unemployment rate increased to 14.9% in the first quarter. Despite these difficult economic conditions, the Turkish wind industry is still one of the fastest growing industries in the country. One reason is that Turkey may face electricity shortages in the near future, furthermore Turkey has just ratified [the] Kyoto agreement which is going to result in carbon emission reduction targets for the post 2013 period.
Among other renewable resources, wind has been the most popular and most approachable power source in the last four years. The use of wind power started around 1,000-1,200 AD in Anatolia, as early as in other European countries. However, Turkey’s development throughout the centuries has not been as fast as that of its counterparts. At the time when Turkey installed its first 0.5 MW wind turbine in Izmir in 1998, Germany had already installed almost 3,000 MW.

The “locavore” movement is big, especially in California. With the bounty of food found locally in the Bay Area, living off the land — and sea — is not only possible, but also a delicious exercise.
But there’s another, less obvious, revolution brewing here in the Bay Area: the “locavolt” movement. In response to high gasoline and natural gas prices, global warming and an increasingly unstable, scary world, people are looking to generate power right in their own homes and neighborhoods with free energy from nature.
Technology advances in computers, telecommunications, generators, inverters, and even cars, are all giving the locavolt new tools to harness renewable energy and lead a fairly normal life.
Within the next few years, plug-in hybrid cars in California will be able to serve as a mini-power generator for your home and store renewable energy from your solar photovoltaics system or your small wind turbine. Plug-in hybrids may also help balance out a smarter electricity grid capable of easily sending power back and forth between generators and consumers, much like we send and receive e-mails on the Internet today.

BrightView Systems, a Petah Tikva, Israel-based start-up developing production process optimization tools for the solar industry, and the Thin-Film Photovoltaics Laboratory at IMT, a world leading lab in silicon-based thin-film solar cells research, part of the Ecole Polytechnique Federale de Lausanne (EPFL), are joining forces to introduce novel solutions for the optimization of next generation thin-film solar cells production.
According to a joint press release, BrightView’s advanced solutions will be utilized to provide real-time feedback to encompass a complete framework for process optimization that is scalable from pilot line to mass production of large area panels.
In January 2009 BrightView finalized a $6 million Series A financing by Israel Cleantech Ventures and Hasso Plattner Ventures. (more…)

The earth is the water planet, so it should come as no great surprise that forms of water power have been one of the world’s most popular “renewable” energy sources. Yet the largest water power source of all – the ocean that covers three-quarters of earth – has yet to be tapped in any major way for power generation. There are three primary reasons for this:
The first is the nature of the ocean itself, a powerful resource that cannot be privately owned like land that typically serves as the foundation for site control for terrestrial power plants of all kinds;
The second is funding. Hydropower was heavily subsidized during the Great Depression, but little public investment has since been steered toward marine renewables with the exception of ocean thermal technologies, which were perceived to be a failure.
The third reason why the ocean has not yet been industrialized on behalf of energy production is that the technologies, materials and construction techniques did not exist until now to harness this renewable energy resource in any meaningful and cost effective way.

Energy demand in Europe is not growing as fast as in other parts of the world but it still constitutes a significant portion of global energy demand. Europe’s share of global primary energy demand is around 14%, although it is likely to decrease to 11-12% by 2030 according to IEA forecasts. While growth is slower than 50 years ago, energy for Europe continues to be a strategic issue.
On July 13 2009, the first international agreement on the Nabucco project was signed in Ankara to ensure gas supply for Europe from the Caspian Region to Austria through Turkey and Eastern Europe. Europeans are to almost 50% dependent on foreign resources for their primary energy demand. Having experienced gas cuts in recent years, resulting in hard times for their industries and residents, Europe would like to become less dependent on Russia by securing its supply from different sources.

IQwind, an Israel-based start-up developing variable gear technology that improves the energy generation efficiency of wind turbines, has raised $500,000 from ISRAEL G-TEK LLC, according to an announcement by the U.S.-based investors.
IQwind received a first round of investment from Terra Venture Partners in 2007.
Sami Shiro and Uri Benhamron, principals at ISRAEL G-TEK, explain that the investment in IQWind is part of their “plan to create a balanced portfolio of greentech companies with a special focus on Israel as a breeding ground for technology.”

With Intersolar taking place in San Francisco this week, solar professionals from all over the world are coming together to network and exchange ideas. The Intersolar organizers have chosen the right city for this conference: The city’s mayor Gavin Newsom is actively pushing towards renewable energy sources. Under his leadership, the City and County of San Francisco started the first local solar energy incentive program in July 2008. Since launching GoSolarSF, there has been a 450% increase in applications for solar installations in San Francisco, from 200 to 850. Last week, Newsom announced plans to install three new solar installations with over 365 kw power on the San Francisco Housing Authority as part of the GoSolar initiative. According to a report issued by Environment California last week, San Francisco ranks third in number of rooftop solar installations in California. On a per-capita basis, San Francisco leads the state’s large cities for rooftop solar.

In a move that will surely provide an additional boost for the alternative energy industry, and perhaps T. Boone Pickens‘ plan, the US Department of Treasury has finally released guidelines for claiming the grants instead of the federal tax credit. Applications will be submitted online. However, the Treasury will not be accepting applications at this time.
The American Recovery and Reinvestment Act passed in February allowed for business taxpayers to apply for direct payments instead of claiming a tax credit on their income tax return. This applied to the credit under Internal Revenue Code (“IRC”) Section 45 (Energy Produced for Certain Renewable Resources) and IRC Section 48 (Energy Credit). Property that applies to this includes geothermal, biomass, micro wind turbines, and solar amongst others.
