The European Commission confirmed on Thursday that it believes legally binding sustainability criteria for biomass used to generate heat and power are not necessary in Europe, thus ending a long process by which the European Union body has debated the utility of a supranational scheme.

The Commission, however, adopted a report on sustainability requirements for the use of solid biomass and biogas in electricity, heating, and cooling. The report makes recommendations on sustainability criteria to member states and encourages them to introduce schemes at the national level.

This strategy minimizes the risk of the development of varied and possibly incompatible criteria at the national level, leading to barriers to trade and limiting the growth of the bio-energy sector in the European Union. (more…)

By now, many have heard algae being proclaimed as the fuel source that could potentially replace a large percentage of the petroleum we use.

However, non-fuel uses of algae that can further lessen our dependence on petroleum have not gotten the attention they deserve. One such usage, while far less visible and but whom some would argue is just as important, is creating plastics.

Cereplast , a renewable plastics company, is looking into using algae as a new and renewable source of this seemingly ubiquitous material. In October 2009, it announced that algae-based resins “could replace 50 percent or more of the petroleum content used in traditional plastic resins.”

In a recent interview, Cereplast CEO Frederic Scheer explained that there are several benefits to switching over to algae-based plastics over traditional petroleum based ones. One reason is that it has the potential to help cut down the United State’s reliance on foreign oil.

“Traditional plastics are made from oil and the entire plastic and chemical industry is using up to 8 percent of our fuel and energy resources,” Scheer said. “In diverting to new [plastic] feedstock we are reducing our dependency [on foreign oil] accordingly.”

Wal-Mart officials have vowed to cut the company’s greenhouse gas emissions by 20 million metric tons by 2015, a sweeping strategy by the retail giant to reduce the carbon footprint of its network of suppliers and stores.

Company leaders say the cuts will more than offset the expected growth of its carbon emissions globally, and represent the equivalent of taking 3.8 million cars off the road.

Initially the company will target the suppliers and producers that emit the highest levels of carbon dioxide. Matt Kistler, senior vice president of sustainability, said initiatives will include cutting the CO2 emissions within the company’s massive transportation operation and reducing waste for fresh foods.

Since diving into the deep end when it comes to energy issues, almost every day sees new concepts, approaches, and technologies — fascinating, exciting, even hope-inspiring at times. And, to top it all off, so many of these are truly Energy COOL as well.

Innovative combinations of rather straightforward, well-in-hand technologies can offer real solutions to problems while creating new opportunities.

Several weeks ago, a group of researchers published an article in the Proceedings of the National Academy of Sciences documenting how relatively low-powered solar systems offer the potential to increase food supplies in impoverished arid regions while reducing demands for fertilizers and other costly (in fiscal and other terms)additives.

Bloom Energy has unveiled its long-awaited and much-hyped fuel cell technology, which it says can convert natural gas into electricity through an electrochemical process that reduces greenhouse gas emissions by 50 percent and at a price competitive with far-dirtier coal-fired electricity.

With California Gov. Arnold Schwarzenegger in attendance, Bloom co-founder and chief executive K.R. Sridhar unveiled his Bloom Energy Server at the Silicon Valley headquarters of one of its first customers, eBay.

Taking up no more room than a parking space and looking like a large refrigerator, the servers (at left) — which cost roughly $750,000 — convert natural gas or another fuel into electricity by creating an electrochemical process on a series of small, stacked disks.

In advance of this fall’s launch of plug-in hybrid and electric vehicles, lithium ion battery manufacturers are breaking ground on manufacturing plants nearly every month.

Nearly $2 billion in stimulus funding has spurred the building of facilities in Michigan and Indiana that will start churning out battery packs by the end of the year, but the escalation in production has the potential to outstrip the demand for the batteries by as early as 2012.

As I said during yesterday’s interview on NPR’s “All Things Considered,” the battery companies have understandable but potentially misguided motivations to quickly ramp up production. For battery companies to receive the full amount of stimulus grants and loans, they must meet specified goals for production capacity.

A rising Asian nation leverages labor advantages to adapt Western technology to lower cost fabrication, and its leading companies rise as no-frills leaders in an emerging global market.

Thanks to free trade policies – kept in place, in part, to satisfy Western consumer demand for the product in its most afforable form — the Asian nation finds a ready export market that helps to build a worldwide brand and return immense profits.

Then, given a generation to develop a domestic engineering and technical workforce worthy of their place in the industry, the Asian nation’s concerns soon come to surpass their Western competitors and they bypass the godfathers of the business in innovation and quality, while retaining an edge in affordability.

Ring any bells?

Most would agree that smart grid is the most happening sector in the clean tech industry right now. It is trying to revamp our outdated and inefficient electrical grids through digital technology. The goal is a green grid which will bring us power savings and lower carbon dioxide emissions. The savings come at a steep up-front cost though –- an estimated $520 billion, according to a McKinsey report.

The transportation sector wasn’t included in the study, and neither was a value set for carbon emissions. The savings could be considerably greater if a value is pegged to carbon emissions, an additional 8 percent at $30 a ton.

Of late we have seen many companies trying to take on the energy management challenge from the user’s end. Home energy management products that control appliances at consumers’ homes to save energy, reduce cost and increase reliability and transparency is an integral part of smart-grid strategy.

The burning of solid urban waste, sludge from water treatment plants, and livestock slurry could generate more than 7 percent of Spain’s electricity needs, according to a new report.

Researchers at the University of Zaragoza say incineration of these materials has the potential to produce up to 20.95 terawatt hours annually. In 2008, that would have met 7.2 percent of the nation’s electricity demand, according to the report published in the journal Renewable Energy. (more…)

The personal care industry has long demanded stricter standards for products labeled “natural,” and in February, the Natural Products Association (NPA), the group representing retailers and manufacturers including Whole Foods and Clorox Co., has released new standards for home-care products.

These include household cleaners for bathrooms and kitchen countertops and laundry detergents.  Up until now, there has been no definition of the term “natural” within the home-care products industry.

Daniel Fabricant, NPA vice president of scientific and regulatory affairs, has been quoted as saying that many so-called natural cleaning products contain largely synthetic ingredients.  And consumers are already confused about what makes products natural as well as organic.
