A post-Katrina homebuilding project gives hope for weathering severe storms

When Hurricane Katrina made landfall in Mississippi on August 29, 2005, the storm’s 125-mile-an-hour winds and 25-foot wall of seawater ground homes, boats, and businesses into matchsticks across the state’s three coastal counties: Jackson, Hancock, and Harrison. The cities of Waveland and Bay St. Louis, roughly 20 miles east of the Mississippi-Louisiana state line, were […]

Fifteen years after the Great Flood of 1993, floodplain development is booming

Once it was a cornfield; now it’s a Wal-Mart, a Taco Bell, a Target. Here along a stretch of Missouri’s Highway 40, in the Chesterfield Valley area just west of downtown St. Louis, what’s said to be the largest strip mall in the country sits on about 46 acres of Mississippi River bottomlands. Less than […]

A post-petroleum American dream

"This craziness is not sustainable," concludes The New York Times op-ed columnist Bob Herbert, and he's talking about the economy, not the environment. He continues:

Without an educated and empowered work force, without sustained investment in the infrastructure and technologies that foster long-term employment, and without a system of taxation that can actually pay for the services provided by government, the American dream as we know it will expire.

And without petroleum. Oil is shooting over $100 per barrel, caused ultimately by a looming decline in global supply, and exacerbated by rising demand in China and India, foolish policies such as the occupation of Iraq, and repressive regimes such as in Nigeria. And if we are serious about reducing carbon emissions to near zero in order to avert climate catastrophe, we must scale back our use of petroleum to near zero.

While we're learning to live without petroleum, we need to rebuild the workforce, infrastructure, technologies, and tax system, as Herbert suggests. I will argue in this post that we can accomplish all of these goals by replacing internal combustion engines with electric motors, using other energy sources for other petroleum uses, and perhaps most importantly, by changing the arrangement of the buildings, production, and people in our society in order to eliminate the need for so much petroleum.

In order to understand how to accomplish all of this, we need to know how petroleum is used, so let's look at some numbers!

A fun traffic simulator and lessons learned

Via Brad Plumer: a traffic jam in in a bottle.

To me, it's pretty remarkable how closely the real-world experiment above matches up with this java-based computer traffic simulator.

New certification planned by safety group

Maybe this all makes more sense to green builders than it does to me, but I see news today of plans to develop another new green-building certification, this one sponsored by the International Code Council. It seems like only yesterday three weeks ago that the National Association of Home Builders launched its own “education, verification, […]

The next generation of infrastructure should help more Americans go carless

It appears that oil has reached a new all-time high in real terms. Given that gas prices normally peak during the summer season, the stage could be set for some ugly pump prices this year, although expensive oil may not be the most painful part of the current commodity price boom for consumers (an honor […]

Deep thought of the day

As rising energy prices and better urban planning push the affluent back to city centers, the poor and working class will be pushed out to the suburbs. Soon, we’ll see blight, crime, the drug trade, and other social pathologies where we have been accustomed to seeing the American Dream. “Inner city” and “outer suburb” will […]

How to kill coal in 10 years

We know that coal is the enemy of the human race, what with carbon emissions, deadly air pollution, and unsafe and destructive mining practices. The supply of coal is becoming more problematic as well: recently, a Wall Street Journal article described a "coal-price surge," and Richard Heinberg has warned that coal may peak much sooner than most people expect. So what's to like? Not much.

But since coal-fired plants provide almost half of our electricity, we can't get rid of coal unless we find either a way to replace it or a way to reduce the use of electricity. Recently, Gar Lipow has discussed how friggin' cheap it would be to replace coal, and Bill Becker has pointed to several studies that show how renewables could replace coal.

I will argue in this post that if buildings could produce all the space and water heating, air conditioning, and ventilation that they need, we wouldn't need any coal. Heating and cooling buildings and water now consume 30 percent of our electricity and 32 percent of our natural gas.

If, for instance, geothermal exchange units (also known as geothermal heat pumps) were installed under every building, and an appropriate amount of solar photovoltaics were installed on roofs in order to power those units, we wouldn't need to burn 60 percent of our coal because we would not need 30 percent of our electricity. And because we could redirect our natural gas from warming and cooling into electricity generation, we could get rid of the remaining coal, replacing it with natural gas.

In other words, the buildings would both destroy electrical demand and free up natural gas, until renewables come online and replaced natural gas in turn. If we did this within a 10-year timeframe, we could generate millions of green-collar jobs, create new industries, and help the rest of the world kill off the rest of coal.

All of the data that I use in this post is available online in a spreadsheet I created called "EnergyUse." It has tabs for electrical use, natural gas use, my calculations concerning coal, and some notes on the data, all of which comes from the Department of Energy's Energy Information Administration (EIA).

So let's get electricity literate, and take a look at how electricity (and natural gas) are used in this country, so that we can figure out how to kill coal:

There are limits to the positive environmental change we can expect from high gas prices

You can scarcely pick up a paper or turn on the television these days without hearing the word recession. Leading economic indicators have wiggled in different directions over the past few months, but the general trend appears to be negative. The conventional wisdom points toward an economic downturn of some kind during 2008, and businesses […]
