Dirty Coal, Clean Future To environmentalists, "clean coal" is an insulting oxymoron. But for now, the only way to meet the world's energy needs, and to arrest climate change before it produces irreversible cataclysm, is to use coal—dirty, sooty, toxic coal—in more-sustainable ways. The good news is that new technologies are making this possible. China is now the leader in this area, the Google and Intel of the energy world. If we are serious about global warming, America needs to work with China to build a greener future on a foundation of coal. Otherwise, the clean-energy revolution will leave us behind, with grave costs for the world's climate and our economy.

The fire is out on the offshore oil rig Deepwater Horizon. But since the rig sank last Thursday, Coast Guard officials believe about 13,000 gallons (7,400 bbl) of crude oil per day is coming out of the exploratory hole drilled by the rig, about 41 miles offshore from Plaquemines Parish, LA
. "An early suggestion that damage would be minimal because the fire was consuming most of the fuel 'does have the potential to change,' BP official David Rainey told the New York Times

Recently, John Michael Greer
has been exploring a little known idea of the deceased economist E.F. Schumacher
(a student of the oft-discussed Keynes
). "Schumacher drew a hard distinction between primary goods and secondary goods. The latter of these includes everything dealt with by conventional economics: the goods and services produced by human labor and exchanged among human beings. The former includes all those things necessary for human life and economic activity that are produced not by human beings, but by nature. Schumacher pointed out that primary goods, as the phrase implies, need to come first in any economic analysis because they supply the preconditions for the production of secondary goods. Renewable resources, he proposed, form the equivalent of income in the primary economy, while nonrenewable resources are the equivalent of capital; to insist that an economic system is sound when it is burning through nonrenewable resources at a rate that will lead to rapid depletion is thus as silly as claiming that a business is breaking even if it’s covering up huge losses by drawing down its bank accounts."

Pond scum saves the planet? In the beginning, there were algae, but there was no oil. Then, from algae came oil. Now, the algae are still there, but oil is fast depleting. In future, there will be no oil, but there will still be algae. ^ Power your ride
with pond scum. In some iterations
you don't even need light
. (we have talked about this before
and the fact that CO2 powers the algae production is not insignificant) More details here

Wal-Mart and the Light Bulb
[NY Times link] - Wal-Mart officials admit their push to sell 100 million compact fluorescent lights
per year is at least partially a marketing ploy, but if successful, it would increase the number of the energy-efficient bulbs in use by 50% while "saving Americans $3 billion in electricity costs and avoiding the need to build additional power plants for the equivalent of 450,000 new homes." Wal-Mart's environmental record is less than perfect
, of course, but if they managed to pull this off it would be hard to see it as a bad thing.

"What is it? A cottage? A Trailer? A Home? All of the above. Technically, the miniHome is classed as an RV - or recreational vehicle (yes, it is on wheels!) but it is designed to work as a comfortable, year-round dwelling in extreme climates. While we see it as the future of sustainable housing and urban infill, it is ideally suited as a ski chalet, cottage, vacation retreat, guest cabin, a place for the kids or family - basically as a luxurious yet simple home-away-from-home." Welcome to life off the grid in Ontario.

of the mind
: Of kids, lies and Oil
. The American Petroleum Institute partners
with The National Science Teacher's
(NSTA) and Scholastic
(see: Scholastic's creedo
provide K-12 lesson plans, on energy and oil, which resemble the API's own "Teacher Lesson
and snappy flash presentations
such as Progress
which are bundled with fun stuff
cool facts. The NSTA/API lessons teach all about energy and oil except the global environmental impacts
. Didactic bonus from NSTA's
oil-friendly curriculum : a surrealistic gallery of oil industry
for kids to download.

is a filter site for discussion about sustainable energy. Their goal is to get a million people worldwide talking about energy. Members can post to a main discussion page
, create profile pages including their own journals and indentify their connections with other members. The chattiest people get free samples of neat products to review
, closing the communication loop for green companies. They're also giving away $50,000 USD in home energy renovation funds to one lucky person.
Innovators have their own space
to collaborate on ideas and projects. They're even offering partnerships
consisting of private discussion areas for any non profit that wants one.

An alternative means towards alternative energy?
Duke Energy in NC is offering its customers an opportunity to vote for alternative energy sources with their wallets starting today. While you are not really buying the Green Power directly, you are in effect subsidizing it. Is this a creative way to Go Green, or just another feel good gesture?

A kilometre-high solar tower,
to be built in the Australian outback by EnviroMission Ltd
, will become the world's tallest structure when completed in 2006. Designed by Jorg Schlaich of Schlaich Bergermann und Partner
, the solar tower (or solar chimney) operates like a hydroelectric power plant, but uses hot air instead of water
, and it could provide enough electricity for 200,000 homes. Time calls it one of the best inventions of 2002
, and I think it's one of the most ingenious ideas I've ever heard. Another solar chimney project was planned in Rajasthan, India
, but I haven't found any information on its current status.

Clean air? We don't need no stink'n clean air.
"The White House firmly defended Energy Secretary Spencer Abraham on Tuesday as newly released documents showed he held at least eight private meetings with industry leaders -- but none with environmentalists -- while the administration crafted its energy plan." Is this really a surprise?
