A plumber explains the “Bathtub Model”

Have you heard of the “Bathtub Model” for expaining CO2 accumulation? I hadn’t until last week, when I attended the sustainability symposium at Baldwin-Wallace College. Dr. Susan Solomon, who was the lead author of th 2007 IPCC report on global climate change, was the one who introduced the concept. Here’s a much more succinct description from, appropriately enough, a plumber.

Picture a bathtub with a running faucet and open drain. When we use energy, carbon dioxide (CO2) pours into the atmosphere just like water pours into a bathtub. If water pours into the tub faster than it can drain out, the tub fills with water. The bathtub stays full until more water is draining out than is pouring in. The same concept applies to CO2. At our current rate of energy consumption, CO2 emissions produced by burning fossil fuels are pouring into the atmospheric bathtub twice as fast as they are draining out.

Everyone can do something about CO2 emissions, and some of those changes are relatively easy to make – as the good folk at Raymond Plumbing go on to explain. For instance, using high-efficiency heating and cooling and Energy Star certified appliances. Even simple steps, like turning down the thermostat on the hot water heater will help – and save money, too.

Where The Green Jobs Are – How to Find Them, How to Get Them

Want to find a job in green energy? Here you go. You’re welcome.

This map of renewable energy and energy efficiency companies from the Environmental Defense Fund is just plain cool:

The Environmental Defense Fund (EDF) recently published an online map that identifies and profiles more than 1,200 companies in key manufacturing states that they see as poised create new jobs when Congress passes a cap on global warming pollution. The interactive map spotlights companies located in manufacturing regions, including those in communities in the rust belt and coal country.

from the ZDNet photo galleries:

The Boston Architecture School and Tufts University are building the Curio House, a home that’s designed to run entirely from solar energy. It’s the Boston area’s entry into the Solar Decathlon, a Department of Energy-run event where student teams from 20 universities compete for the best solar home design.
Curio House

Teams need to take apart and then reassemble their buildings on the National Mall in Washington, D.C., next month where they will be open to the public for 10 days and judged by a panel.The Boston team has focused its design on affordability, making an 800-square-foot building using almost entirely off-the-shelf products and technologies. It has lined up a buyer for the home in Cape Cod where it is supposed to be the first unit in a green housing development. The projected cost of the building, big enough for two people and a small child, is about $200,000. Students, donors, and school administrators held a ribbon-cutting ceremony at the unfinished building on Thursday at Tufts University in Medford, Mass.
