Prof. Albert Bartlett – “Arithmetic, Population, and Energy”


Albert A. Bartlett (1923-2013) was Professor Emeritus in Nuclear Physics at University of Colorado at Boulder. He was a member of the faculty of the University of Colorado since 1950. He was President of the American Association of Physics Teachers in 1978 and in 1981 he received their Robert A. Millikan Award for his outstanding scholarly contributions to physics education.

Dr. Bartlett gave his celebrated lecture, Arithmetic, Population and Energy 1,742 times. His collected writings have been published in the book, “The Essential Exponential! For the Future of Our Planet“. – Break FREE Movement

All over the world this May, thousands of people stepped up their work to Break Free from fossil fuels. This is what it looks like when the movement grows in courage, strength and beauty.

2015 Plastic Pollution Coalition Video

Plastic Pollution Coalition is a global alliance of individuals, organizations, businesses and policymakers working toward a world free of plastic pollution and its toxic impact on humans, animals, the ocean and the environment.

Get started living plastic-free

Disposable plastic items are so common that it’s easy to not notice them. But disposable plastic is everywhere—the ubiquitous plastic bottles of water or soft drinks; the plastic straws delivered in our drinks; the plastic bags offered to us at stores; the plastic cups, bottles and utensils at nearly every social event; the plastic packaging of nearly everything in the supermarket. Once you see it for what it is—plastic pollution—it’s simple to just REFUSE it. Here are some tips to reduce your plastic footprint.

A Resilient Society

Published on May 5, 2015

“Resilience” is the ability to absorb shocks while continuing to function. It’s a word that has gained a lot of currency in recent years as more and more people realize that we have some big shocks headed our way: financial shocks, energy shocks, environmental shocks, as we as social unrest and international conflict.

This video is the last in a four-part series by Richard Heinberg and Post Carbon Institute. The themes covered in these videos are much more thoroughly explored in Heinberg’s latest book, Afterburn: Society Beyond Fossil Fuels.

Transition Streets

While the Transition Towns movement spurred hundreds of households in dozens of cities to take individual actions to save water, reduce emissions, and turn to renewable energy sources, the Transition Streets movement takes that effort to the streets, literally. Key to the effort is a seven-session handbook that can be downloaded for use by groups of neighbors to help them reduce waste, improve energy efficiency, conserve water, and explore ways to eat and live healthier lives.

300 Years of FOSSIL FUELS in 300 Seconds

Fossil fuels have powered human growth and ingenuity for centuries. Now that we’re reaching the end of cheap and abundant oil and coal supplies, we’re in for an exciting ride. While there’s a real risk that we’ll fall off a cliff, there’s still time to control our transition to a post-carbon future.
