However, according to a report from the U.S. Energy Information Administration, during the first half of 2008, renewable sources made up more than 10% of all domestic energy production.

For the period January 1 - June 30, 2008, the United States consumed 50.673 quadrillion Btus (quads) of energy - of which 34.162 quads was from domestic sources and 16.511 quads was imported.

Domestically-produced renewable energy (biomass/biofuels, geothermal, hydropower, solar, wind) totaled 3.606 quads — an amount equal to 10.56% of U.S. energy consumption that is domestically-produced.

Australia has been suffering through a drought for the last several years. Since 2003, most of Australia has been experiencing the most severe drought conditions on record. And Australia is the driest populated continent, which further exacerbates water issues there. So it’s not surprising that a super-efficient shower would come from Australia.

According to the Quench Showers brochure, “If we focus on Australia’s water position we are at crisis point. Being aware of this is a start, but more importantly, we all need to understand the crisis and take immediate action if we are going to influence change. Without changing the way we consume and manage our water usage in our day-to-day activity, this crisis will become a widespread catastrophe!”

So how does the Quench shower save so much water and energy?

Under the four-year proposal, the Liberals would offer homeowners $10,000 in financial support for investing in energy-saving measures such as insulation, weatherproofing and more efficient heating systems.

Up to $10,000 would also be available to homeowners as an interest-free “green mortgage loan” to help with up-front costs and major retrofits.

But small-scale turbines are perhaps a more exciting realm of development. The standard, propeller-style turbine is well established, and there are many suppliers for this kind of generator in a range of sizes. In 2007, Home Power Magazine had a roundup of more than a dozen small wind turbines ranging from 8 feet to 56 feet in diameter (the latter of which is far larger than even a large, inefficient household would need for their power requirements). Green Building Elements had a review of this article last year.

Designer Hafsteinn Juliusson has found a compelling image for this series of designs of rings with living plants in place of precious stones or other mineral elements more typical to jewelry.

The designer says of the design, “The collection of this hand jewelry is designed for people in metropolitan cities and is an experiment in drawing nature toward man, as nature being the presupposition of life.”

Black water is toilet waste and other water that requires more substantial treatment.  Grey water is non-sewer waste water from washing clothes and showers and the like.  Although in most homes, both black water and grey water go into the sewer system and are handled in water treatment plants with the same processing, grey water really requires much less treatment. It is possible to find other uses for grey water, including using the water for toilet flushing or for irrigation.

One goal of the team developing this technology is to be able to build a house in a day, a goal that they hope to reach within the next few years.  There is some merit to this goal, and the benefits of being able to rapidly and inexpensively produce houses are obvious, though not without some attendant problems.

“Satellite images gathered by NASA show that the north-west passage opened last weekend and the final blockage on the east side of the ice cap, an area of sea ice stretching to Siberia, dissolved a few days later.”

Whether or not you subscribe to the concept of global climate change due to human factors, there is no dispute that, for the first time in recorded human history, the North Pole is an island, with unobstructed sea between the Pole and both Canada and Russia.

“Measurements on August 26 showed an ice cap of just over two million square miles, confirming the second biggest ice cap melt since records began.”

The extension of suburbs further and further out from the core of businesses and services not only consumes acres of land, with its attendant loss of woods, fields, wetlands, farmland, and animal habitat, but it also requires miles of pavement, and the attendant infrastructure (sewers, phone and power lines, etc.) to support the new development. Residents of these displaced communities are forced to rely on cars for more and more of their access to various services and amenities, and very often travel greater distances to work as well as other destinations. This increases both the consumption of fuel resources and the pollution caused from the extra travel.

The Midwives Alliance of North America (MANA) annual conference will be held in Traverse City, Michigan later this October. MANA is a professional organization for midwives throughout North America. “MANA’s goal is to unify and strengthen the profession of midwifery, thereby improving the quality of health care for women, babies, and communities.”

You can help support the work of midwives.  MANA is working to push legislation in a number of states where the practice of midwifery and homebirth is not fully legal.  While some states have laws that support and encourage the practice of midwifery, many other states are less supportive.  MANA is also advocating for insurance companies to allow homebirth options as a safe, less-expensive and less resource consuming alternative to standard hospital births.

The 2008 Olympic Games in Beijing are supposed to be the greenest yet. There has been some coverage on television, and despite all the attempts to clean things up beforehand and to limit especially the air pollution during the games, pictures from the city show it still in many ways to be a smoggy, grimy place. It’s not wholly bad, however. The buildings constructed for some of the competitions are architecturally striking, and they seem to be a functional success, as well. But how do they stack up as green buildings?

Sometimes, some of the greenest solutions come from the simplest of ideas.  Take the cottage community.  What could be simpler than the idea of building houses that are radically smaller in square footage than the national average?  Not everyone wants all that extra space, and many would rather have a smaller home built well than a cheaply made box full of emptiness.

Cottage communities are not yet widely known in planning and development.  Cottage communities are primarily located in the Pacific Northwest, though there are indications of interest, if not actual communities yet built, in other parts of the country.

The individual cottages have a small footprint.  The first cottage community built in Langley WA had half the cottages no bigger than 800 square feet, and the other half no bigger than 700 square feet.  These homes are far smaller than the average size house in the U.S. (which was almost 2,400 square feet in 2004).

Cottages serve a niche community.  Obviously, a family of more than 3 or 4 people would start to feel crowded living the typical American lifestyle in such a space.  But many households have only one or two people, and a 700-800 square foot house is perfectly adequate for them.

Cottages work best where several cottages can be placed near one another.  If you still require a full size lot for every home, a cottage doesn’t really do anything towards reducing sprawl.  But a cottage development typically has twice the number of houses as would normally be permitted.  So a piece of land that could normally accommodate four houses can be developed with eight cottages.  By developing as a community, cottages also benefit from common amenities such as landscaping and shared parking areas.  (The small size of the cottages precludes attaching garages to them.)

While cottages reduce the amount of land needed for development, they also reduce the volume of resources needed in their construction.  It is intuitively obvious that an 800 square foot cottage takes much less material, from studs and shingles to pipes and cupboards, than an average sized 2,400 square foot home.  In addition to all that material saved, the smaller cottages also need fewer resources to keep them heated and cooled.

Cottage communities can break up the texture of an otherwise undifferentiated development, and provide opportunities for other kinds of owners to be added into the housing mix.  While they serve the needs of a limited part of the population, they can contribute to better communities with just a simple idea.

The system uses lightweight formwork panels, much like those used for poured concrete walls. Once erected, the forms are filled with mortar (concrete without stone) which can be hand-mixed and hand-placed, or which can be mechanically mixed and pumped into place. Typically, the formwork can be removed the day after the mortar is poured. The result is a smooth finish material, little more than a roof is needed to complete the building.

On the downside, this material uses 250 kilograms of portland cement per cubic meter (about 420 pounds per cubic yard), making it fundamentally the same as a concrete building with an enormous carbon footprint stemming from the extensive use of cement in these buildings.

Science-fiction author and journalist Bruce Sterling, who founded something called the Viridian Design Movement back in 1998 has posted the text of Gore’s speech interspersed with his own comments (((which he nests in triple parentheses))).

It makes an interesting document that much more fun to read:

We’re borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the planet. (((Or, “American politician schemes to save civilization.” Hey, it’s a plan. Who else has got such a plan? Any similar politician of any other country? No, I didn’t think so.)))

I recently got a press release from a company advertising a product to quickly and easily “convert” recessed can lights to a pendant light look.  But, after a brief look, it turns out to be a particularly bad case of greenwash.
