Follow the Coal Money

Sheryl CanterThis post is by Sheryl Canter, an online writer and editorial manager at Environmental Defense Fund.

Environmental Defense Fund can’t comment on the candidates in this year’s historic election because of our tax status as a 501c3 charitable organization. But it’s okay for us to provide interesting sources of information, and here’s one: a site that tracks which lawmakers receive money from the coal industry.

It’s very detailed and very interesting, with multiple ways to browse or search. Take a look!

20 Energy Solutions – From You

Sheryl CanterThis post is by Sheryl Canter, an online writer and editorial manager at Environmental Defense Fund.

Yesterday we sent an email to our action network asking how people were coping with high oil prices. The response on our sister blog, the Green Room, was enthusiastic – over 600 comments! Here are some of our favorites, organized by topic:

Strategies to Increase Gas Mileage

From Ann:

I’ve been driving 60 mph on the highway and have seen a dramatic improvement in my gas mileage. I’m getting 38-40 mpg in my Toyota Camry on the highway! Drive 60 when you go.

Muscle Power: An Alternative Fuel?

Sheryl CanterThis post is by Sheryl Canter, an online writer and editorial manager at Environmental Defense Fund.

When I went out to get lunch yesterday, I passed a sporting goods store with an interestingly labeled sneaker display. I’d never thought of my feet as an "alternative fuel" before, but I guess that’s right!

Sneakers as Alternative Fuel

Human movement isn’t just for transportation. Take a look at last Thursday’s post for examples from around the world of how human movement can be used to generate electricity. Investment spurred by cap-and-trade legislation will make clean energy technologies like these the norm rather than the exception.

Immense Flat Roofs, an Untapped Resource

Sheryl CanterThis post is by Sheryl Canter, an online writer and editorial manager at Environmental Defense Fund.

Yesterday’s New York Times reported that a number of chain stores, including Wal-Mart, Macy’s, Safeway, and Whole Foods, are putting solar panels on their roofs to generate electricity. There’s a big opportunity here. Stores are the largest energy users in many communities, and solar panels could generate 10 to 40 percent of the store’s electric needs.

Solar power still costs more than electricity from coal, but:

[R]etailers believe that they can achieve economies of scale. With coal and electricity prices rising, they are also betting that solar power will become more competitive, especially if new policies addressing global warming limit the emissions from coal plants.

Blog Buzz: Electricity from Human Movement

Sheryl CanterThis post is by Sheryl Canter, an online writer and editorial manager at Environmental Defense Fund.

The idea of generating electricity from human movement isn’t new, but recent advances make it practical in a way it never was before. This CNN article gives a good overview of how the technologies work, and where they are in use. For example:

The floor technology can be used in more than just dance clubs. Any large crowd will produce vibrations. Sustainable Dance Club also has received requests for floors from bus and train stations, where it can be used to power lights and display boards.

And there’s more!

Why Climate Projections Have Error Bars

Lisa MooreThis post is by Lisa Moore, Ph.D., a scientist in the Climate and Air program at Environmental Defense Fund.

In 1992, the world’s nations gathered to negotiate the United Nations Framework Convention on Climate Change. The 192 nations that ratified this treaty – including the U.S. – agreed to the following objective:

[T]o … prevent dangerous anthropogenic interference with the climate system… within a time-frame sufficient to allow ecosystems to adapt naturally to climate change, to ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner.

The definition of "dangerous" is a social and political judgment that is informed by science. But even if we all agreed on which outcomes we wanted to avoid, scientists couldn’t say precisely how much we have to cut emissions to achieve these outcomes. We have good best estimates, but there’s always a degree of scientific uncertainty.

Here’s why.
