CONVERTING a greenhouse gas into a clean-burning fuel offers two benefits for the price of one. That's the thinking behind a novel process for converting carbon dioxide into methanol at room temperature, developed by a team at the Institute of Bioengineering and Nanotechnology in Singapore (Angewandte Chemie International Edition, DOI: 10.1002/anie.200806058).

Homeowners this fall will be able to buy a wind turbine at hardware stores that tackles the small wind industry's bete noire: slow wind. WindTronics has developed a wind turbine sized for individual homes that it says can operate at speeds as low as 2 miles an hour. It will be sold for $4,500 as the Honeywell Wind Turbine... ... generate 2,000 kilowatt-hours in a year for a home with a very good--called Class 4--wind resource, according to the company. That's between 15 and 20 percent of the annual electricity consumption for the average U.S. home.

Until November it was virtually impossible for a private developer of renewable energy power plants to become an independent power producer (IPP) in Mexico. Article 27 of the Mexican Constitution precluded private investment stating that electricity generation for public use is an activity to be undertaken exclusively by the Government. Mexico's enactment of a new law for the use of Renewable Energy and the Financing of the Energy Transition ( Ley para el Aprovechamiento de Energías Renovables y el Financiamiento de la Transición Energética ) substantially improves the legal framework for private investment in renewable energy projects. The law regulates renewable energy electricity generation for purposes other than providing public electricity services. The law states that the use of renewable energy for electricity generation is possible for private use and any excess energy can be sold, but only based on regulations and approvals by Mexico's energy regulatory body, CRE .

"GlycosBio has commercialized glycerin-eating microbes developed by Rice University.Like some 21st-century version of The Blob, a thick, gooey tide of glycerin is overwhelming world markets."

"The renewable energy map has been developed to fill what seems to be a gap in information about the major renewable energy schemes in the UK. Though there are a number of lists and project details available, these are often developed to indicate a point in time or a specific technology. The BWEA is an example of the latter, an excellent resource but specifically focused on wind. The data that has been gathered for the renewables map has invariably come from a wide range of web resources, in all cases these will be referenced, usually by a link to that information. Locations are either taken from existing data, usually from planning applications, or by painstakingly identifying the location on the ground using online maps. There are of course errors (such as landfill's at sea), though these are corrected as soon as they are identified."

"BEIJING--CHINA will build an "industrial system" and "consumption pattern" with low carbon emissions, Premier Wen Jiabao said in the government work report delivered at the parliament's annual session yesterday. The country will work hard to develop low-carbon technologies as well as new and renewable energy resources to actively respond to climate change, Wen said at the session of the National People's Congress, adding that the development of smart power grids should be intensified. "

This merits revisiting. With the recent collapse of the Spanish market, the correction of the German market and the expected collapse of the French PV market, FITs prove unsustainable or victim of their own success. Once the market picks up, governments can no longer support their price tab. Moreover, they are based on a false premise: the cost of taking a technology through the learning cycle is prohibitive - it requires too many tens of billions.

The topic is complex. Some underlying questions: * Why promotion of renewables was set-up? * What is the complete economic balance of renewables promotion? (expenses in subsidies, but savings in fuel imports, job creation, exports.... some interesting studies have been done on this - see for instance Macroeconomic study on the impact of Wind Energy in Spain - http://www.aeeolica.es/userfiles/file/aee-publica/091211-executive-summary-2009.pdf) * Is the allocation of subsidies cost done correctly? Electricity consumers often pay extra-cost, but benefits go to other pockets. Should there be a cost re-allocation to make the model sustainable? * Is regulatory framework evolving less rapidly than technology? FITs on PV in 2008 could be significantly reduced compared to FITs in 2007, and so on. How to accomodate regulation to that quick cost reduction? * Had governments defined a cap in global subsidies amount? Not really, this explains why they are all reacting to initial plans. * Development of technology and market drives costs down. Why some few countries should make this investment to the benefit of the entire world? * Have we excessively promoted market growth and neglected technology development? Are we paying too much for building power plants with primitive technology?

@Fernando - I agree that the topic is complex. However, I'd refrain from making claims on employment effects. This is an area where secondary effects are rarely taken into account. While I realise these claims are popular, basically nobody knows.

The development of renewables in an oil state - worth an article on Leonardo ENERGY? Or a story already told too many times?

"The Chilean government has set its sights on significantly increasing its geothermal energy capacity. The Ministry of Energy recently announced a new contract for the development of 20 areas by 2012. 70 bids from 13 domestic and foreign firms were submitted for the rights to exploit the newly released regions of Rarapacos and Los Ricos. Earlier in the year, Energy Minister Ricardo Raineri announced more than 170 concessions for geothermal energy by 2012. He further specified that these concessions would be supported by US$200 million in funding from the government. The country is striving to increase its geothermal capacity to 1,000 megawatts in order to meet an ever-growing energy demand in a sustainable manner"

"it was all summed up clearly for me by members of COPAGEN, a coalition of African farmer associations, scientists, civil society groups and activists who work to protect Africa's genetic heritage, farmer rights, and their sovereignty over their land, seeds and food. All these knowledgeable people have shown me that the answer is quite straightforward: many of those imported mistakes, disguised as solutions for Africa, are very, very profitable. At least for those who design and make them."

BASF, RWE Power and the Linde Group agreed recently to develop a new processes for CO2 capture from combustion gases in coal-fired power plants. The collaboration will comprises the construction and operation of a pilot facility at the lignite-fired power plant of RWE Power AG in Niederaussem/Germany

Siemens started working with Norwegian utility Statkraft earlier this year to develop a CO2 capture technology that suit the conditions and mode of operation of combined cycle plants.
