Japan has announced plans to build its first new geothermal power stations in nearly two decades in a bid to tap the nation's domestic energy sources. A string of geothermal power plants are to be developed by a number of firms keen to capitalise on the active volcanic landscape that spans the country, while the government is also currently compiling guidelines supporting the development of such energy sources. Home to 108 active volcanoes - ten per cent of the world's active volcanoes - Japan is in a prime position to tap into underground geothermal energy sources. As a nation with few natural resources, Japan has long been dependent on importing substantial quantities of crude oil and natural gas. The country's renewed focus on geothermal energy marks a desired shift away from its dependency on imported energy sources which has made it susceptible to increasingly volatile prices.

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford. And "clean coal," which involves capturing carbon emissions and sequestering them in the earth, is not clean at all, he asserts.

Matthew Simmons has received quite a bit of press in the past week, after his Ocean Energy Institute floated a proposal to build a $25 billion, 5 GW wind farm in the Gulf of Maine. Offshore wind farms have a number of advantages over their land based equivalents - they are less hazardous to wildlife, have fewer objections raised on NIMBY concerns and winds are generally stronger over the oceans than they are over land.

Spain has set a record this week by powering 29-40% of its electricity needs from wind energy. A huge 11,180 MW was generated on Thursday when high winds blew through north west Spain. When demand was lower early in the morning, wind energy supplied 40% of the country's requirements whilst later on when demand rose, wind energy supplied 29%. This year wind turbines have supplied 11.5% of electricity demand in Spain positioning the country as the third biggest producer of wind energy next to Germany (second) and the US (first). There is a national target of reaching 20,000 MW by 2010. This compares with a figure of just 7300 MW likely to be operational in the UK by 2010 (the number currently built or with planning consent). Companies with a significant presence in Spain are Iberdrola, Acciona and Endesa.

With the rise in biodiesel production, the growing number of US states adopting legislation for the use of biodiesel, and an expectant market, there is also an increasing demand for biodiesel fuel specialists.

So far, CNG vehicles haven't made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles. There are about 1500 CNG refueling stations in the US, which is about the same number of commercial stations offering E85 ethanol blends. Utah has a total of 91 CNG filling stations, most of which are reserved for commercial fleet use, but there are 20 open to the public. According to an article by the Associated Press, you could drive Utah from top to bottom and hit 22 different stations offering compressed natural gas.

The behavior of this particular female firefly is doubly remarkable because adult fireflies rarely, if ever, eat anything. However, a number of these female cannibals have been found to be carrying eggs at the time they attack. It may be that they need extra protein at such a time - and have found an expedient and seemingly effective way to acquire it.

Renewable Energy World has an article on some large scale efforts to map geothermal power resources in the western US - Western U.S. Entities Move Quickly on Geothermal Mapping. Several large geothermal resource mapping projects are heading toward conclusion so that finally, the power source can be more accurately considered in siting new electricity transmission lines for renewable power development. Given the Obama administration's investment focus on new transmission line development, the result of the mapping efforts should be a relatively rapid increase in the number and size of commercial-scale geothermal projects.

At the recently held EWEC 2009 wind energy conference and exhibition most exhibitors agreed that while there has been a substantial business slowdown due to problems linked to obtaining wind project financing, an upturn in demand during the second half of 2009 is beginning to play out, at least in the U.S. Other exhibitors, on the other hand, were a bit more cautious pointing out that substantial numbers of unsold turbines from framework contracts failing to secure project finance are now floating on the wind market. Most interesting from a wind technology point of view is the V112-3.0MW switch away from a compact V90-3.0MW integrated gearbox and main bearing assembly to a 3-point gearbox support. The application of a permanent magnet (PM) type generator with full converter system in the V112-3.0MW is new for Vestas but not for the wind industry. New Technology Trends In what many wind industry insiders consider a major development trend, French aerospace companies EADS Astrium & EADS Composite Aquitaine announced their formal entrance into the wind industry. The French companies offer the wind industry advanced composite materials engineering, manufacturing and related know-how as well as rotor-blade manufacturing capacity.

If China's addicted to solar hot water heating, the city of Dezhou is it's dealer (and one of it's biggest customers). A new video from Greenpeace, above, highlights the build-up of solar among residents and as an industry. Some facts from this shining example: Of the city's 5.5 million residents, almost all living in the new town use solar heating, and about 90 percent of homes in the old town have solar heating. In 2007, 800,000 people had jobs in the solar panel industry, or about one in three people of working age in the city. That figure is expected to grow to 150,000 by 2020. No wonder: Dezhou is home to the world's biggest solar water heater manufacturer. And compared with an electric heater, a solar heater in Dezhou, which starts at about US$190, pays for itself in five and a half years. The numbers in Western countries, by comparison, make us want to shield our eyes.

Global wind capacity increased an estimated 27,051 megawatts in 2008, with cumulative installations up almost 29 percent. The United States led in new installations, surpassing Germany to rank first in wind energy cumulative capacity and electricity generation. Nearly 400,000 people are employed by the wind industry worldwide, though this number could slide in the near term due to project financing difficulties, particularly in the United States. A new snapshot of wind energy trends from Worldwatch Institute analyzes data since 1980 and reveals that for the first time last year, wind power represented Europe's leading source of new electric capacity (with 8,877 megawatts added), well ahead of natural gas at 6,939 MW and coal at 763 MW.

REW reports the world's biggest solar thermal tower has opened in Spain - World's Largest Solar Power Tower Commissioned. Abengoa Solar has begun commercial operations of the world's largest solar power tower plant, a 20 MW installation. The company claims that the performance of the power plant, the so-called PS20, has exceeded its design output in the wake of its three-day production and operational testing period. Located at the Solúcar Platform, near Seville, Spain, PS20 is the world's second power tower plant in commercial use and features a number of significant technological improvements with respect to its predecessor, PS10. These enhancements include a higher-efficiency receiver, various improvements in the control and operational systems, and a better thermal energy storage system. PS20 consists of a solar field made up of 1255 heliostats with a surface area of 1291 square feet each. This reflects the solar radiation it receives onto the receiver, located on the top of a 531 foot-high tower, producing steam which is converted into electricity generation by a turbine. Plant construction was carried out by Abener.
