According to the United Nations, an estimated 40 percent of the global population, or close to 2.6 billion million people do not have access to a toilet of any sort, even a pit latrine.

This has created a public health crisis in developing countries, both in terms of contaminated drinking water and poor sanitation techniques. More than one million children mostly under the age of five die each year from diarrhea resulting from this lack of sanitary conditions. While the technology exists to solve this problem, it is expensive and sometimes hard to install.

But Swedish architect and entrepreneur, Anders Wilhelmson is hoping to tackle the issue with his invention: a safe, affordable, biodegradable plastic bag called the Peepoo that can be used as a single-use toilet. (more…)

IBEW Local 569

Micah Mitrosky is an Environmental Organizer with the International Brotherhood of Electrical Workers Local 569 in San Diego.  She is focused on the renewables sector and talked with CleanTechies about unionization plans for the green industry.

CleanTechies: What is the mission of IBEW Local 569?

Micah Mitrosky: Our mission is to make sure that as our economy shifts to a low-carbon, sustainable economy, that we’re creating middle-class jobs with health care benefits, skilled career opportunities. A lot of what you think of as the fossil fuel sector are middle-class, union jobs. We want to make sure that, as we’re bringing in these new greener technologies and new green ways of doing things, that we’re replacing those with better middle-class career opportunities.

CleanTechies: What’s your biggest challenge in doing that? (more…)

Two billion people worldwide do their cooking on open fires, producing sooty pollution that shortens millions of lives and exacerbates global warming. If widely adopted, a new generation of inexpensive, durable cook stoves could go a long way toward alleviating this problem.

With a single, concerted initiative, says Lakshman Guruswami, the world could save millions of people in poor nations from respiratory ailments and early death, while dealing a big blow to global warming — and all at a surprisingly small cost.

“If we could supply cheap, clean-burning cook stoves to the large portion of the world that burns biomass,” says Guruswami, a Sri Lankan-born professor of international law at the University of Colorado, “we could address a significant international public health problem, and at the same stroke cut a major source of warming.”

Sooty, indoor air pollution from open wood or other biomass fires has long been linked to health problems and deaths. More recently, scientists have been surprised to learn that black carbon — not only from biomass fires but from dirty diesel engines and other sources — is a far larger contributor to global warming than previously suspected: The dark particles absorb and retain heat close to the Earth’s surface that might otherwise be reflected.

The U.S. Congress is coming under increased lobbying pressure from the algal organizations to extend tax code parity to algae-based biofuels.

The Algal Biomass Organization and members of the Biotechnology Industry Organization are urging Senate Finance Committee chairman Max Baucus (D-MT) and Ranking Member Charles Grassley (R-IA) to adopt an amendment offered to the Tax Extenders Act of 2009 by Sens. Bill Nelson (D-FL), Mike Crapo (R-ID), and Jeff Bingaman D-(NM).

The amendment would ensure algae fuels receive the financial and regulatory benefits available to other advanced biofuel feedstocks and promote the development and commercialization of algae fuels. (more…)

Mark Chen is the director of marketing at Abound Solar, a Colorado-based manufacturer of thin-film cadmium telluride solar modules.  Cleantechies sat him on the hot seat for three questions:

CleanTechies:  Unlike many photovoltaic (PV) companies, you are manufacturing in the United States.  Tell me about the company’s decision to do that.

Mark Chen:  Abound Solar was founded in Colorado in 2007 based on research conducted at Colorado State University for over 15 years.  Abound Solar’s manufacturing technology features a continuous semiconductor deposition process on a fully-automated production line.  Our geographic roots and low labor content allow us to be competitive despite higher hour wages in the United States

CleachTechies: Can the United States compete with China’s photovoltaic industry?  What advantages do you offer?

Biofuels in Europe are struggling to meet the most basic thresholds for sustainability, according to the Times of London, which claims to have seen a government study that shows fossil fuels are better for the environment than “green fuels” made from crops.

The findings show that the United Kingdom’s biofuels mandate would result in millions of acres of forest being logged or burnt down and converted to plantations.

The study finds that some of the most basic crops used to make biofuels fail to meet the minimum sustainability standard set by the European Commission. (more…)

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…)

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.

This article has been updated.

In her forthcoming book, Prefabulous + Sustainable, author Sheri Koones sets out to show how beautiful and green a prefabricated home can be.

The book is divided into three categories –- “green, greener, greenest” –- and the homes featured vary in style, design, type of construction and size. Koones walks the reader through each of the homes, explaining the materials, strategies and systems used to create a sustainable living environment. CleanTechies had a few questions about the methodology and the pre-fab industry.

CleanTechies: Tell me how you chose the houses you profiled.

Koones: I was looking for houses that were as sustainable as possible, but also attractive, in various locations of the country using different methods of pre-fab construction, and in city, residential and suburban settings.

CleanTechies: How did you find them and ascertain which ones you wanted to look at? (more…)

CleanTechies is fortunate to have some of the sharpest minds in the energy and clean tech industries as regular readers, but even if you don’t have a Ph.D., you should be able to answer this quick math quiz: “Which price tag is cheaper, $8 billion or free?”

Don’t hurt yourselves!

On Tuesday, President Obama officially announced $8 billion in government loan guarantees for construction of two new nuclear plants in Georgia, the country’s first expansion of nukes in more than 30 years.

A day later, the Vermont state legislature officially began deliberations on the question of relicensure of Entergy’s Vermont Yankee nuclear plant. While there are some transaction costs associated with keeping Vermont Yankee open past 2012, the cost is nowhere near $4 billion.

Given the commitment the president made to clean, domestic nuclear power just 24 hours earlier, you would expect the White House to jump right in on the question of relicensure in Vermont, right? Not so fast. (more…)
