Green Jobs Grow fast

Wired is running an article that points out the outstanding growth of green jobs in the USA and how they already employ 770,000 Americans. Green jobs have grown 250% since 1998.

The report differs from government projections or most industry association estimates in that it counts individual jobs, not entire industries. In other words, only the electricians who actually install solar panels were counted as green electricians.

“Although our numbers are conservative, our report provides the most precise depiction to date of the clean energy economy in the United States,” the Pew researchers wrote.

Green jobs are a major part President Obama’s plan for economic recovery and energy transformation. Manufacturing jobs have declined a few percent a year over the last decade, and in the bullet-point language of Whitehouse.gov, his administration wants to “Drive the development of new, green jobs that pay well and cannot be outsourced.” The report shows that environmentally friendly jobs already exist, but most of the “green” jobs aren’t in clean energy at all. A full 65 percent of the jobs fell into the “conservation and pollution mitigation” category, which includes recycling.

That leaves a lot of room for growth in clean energy, even if some jobs are lost in traditional energy companies. Right now, there’s a small base. There were only 89,000 “clean energy” jobs in 2007. Current research indicates that for renewable energy sources to really make an impact on greenhouse gas emissions and fossil fuel dependence, we’re going to need a lot of manpower.

Green Roofs Changing Architecture

Over at Treehugger they have a good slideshow about the state of green roofs in architecture.

Sometimes they developed naturally and organically, like this rooftop garden in lower Manhattan that like Topsy, just grew. And grew, and eventually evolved from a New York roof garden into what they now call a Green Roof.

A Simple Buoy That Pumps Water

Pumping water into filtrations plants and reservoirs is not really an exciting topic, except when someone invents something that’s so simple that it seems that it should exist. A British inventor has created a pump that uses only wave power that is a self-cleaning device that essentially pumps water for free.

Dubbed ‘Searaser’, it consists of what looks like a navigation buoy, but is in fact a simple arrangement of ballast and floats connected by a piston. As a wave passes the device, the float is lifted, raising the piston and compressing water. The float sinks back down on the tail of the wave on to a second float, compressing water again on the downstroke.

What is particularly clever about Searaser, however, is its simplicity. Where most marine energy devices have sealed, lubricated innards and complex electronics, Searaser is lubricated entirely by seawater, has no electronic components and is even self-cleaning. Smith describes it as ‘Third-World mechanics’, but this belies the sophistication of the concept.

‘The beauty of it is that we’re only making a pump, and bringing water ashore,’ he explains. ‘All the other technology needed to generate the electricity already exists.’

The Self-Sufficient City

Looking to save the world? Then enter the international competition to design the self-sufficient city. One of the goals is to spur some online discussion, so what do you think the city of the future will look like? And will you enter the contest?

The competition jury, which is composed of architects, directors of some of the world’s foremost architecture schools, and mayors of cities such as Barcelona, is looking for outstanding proposals for any city in the world, at any scale, and within any timescale. Competition entries should be submitted via the Internet (www.advancedarchitecturecontest.org) on Connected metropolises, Eco neighborhoods, Self-sufficient buildings, Intelligent homes or any other proposal for a short-, medium or long-term project to create habitats that respond to the social, cultural, environmental and economic conditions that may obtain in the 21st century. The proposal should include whatever texts, drawings and other images may be needed to make it fully understandable.
The competition prizes will consist of three scholarships for the IaaC Masters in Advanced Architecture for academic year 2010-11, cash prizes, and the latest generation of large-format HP printers. The selected projects will go on show in a major exhibition, due to open in Barcelona in May 2010, which will then travel to key cities around the world. The best projects will also be featured in a book to be published by Actar. The project is supported by the Spanish Ministry of Housing, the Generalitat de Catalunya, Barcelona City Council, and the publishing house Actar.
