Trouble in the algae lab for Craig Venter and Exxon

by

A much-trumpeted partnership of one of today’s most celebrated scientists and the world’s largest publicly traded oil company seems stalled in its aim of creating mass-market biofuel from algae, and may require a new agreement to go forward. The disappointment experienced thus far by scientist J. Craig Venter and ExxonMobil is notable not only because of their stature, but that many experts think that, at least in the medium term, algae is the sole realistically commercial source of biofuel that can significantly reduce U.S. and global oil demand.

When will we admit that our corn ethanol policy is immoral?

by

Having just returned from a trip to Eastern Nebraska, I feel as if I participated in a movie set for “The Road” or its equivalent. It’s all about ethanol in this region of the country and it’s not a pretty sight. Because of our unbridled and unquenchable thirst for liquid fuels, this policy is creating a vast environmental ruin not so different from that of the tar sands areas of Canada. In recent years, this land which was a prairie a short one-hundred-and-fifty years ago has become a region that produces primarily only two industrial agricultural crops, corn and soybeans.

Review: Life Without Oil by Steve Hallett With John Wright

by

“Imagining a world without oil” describes in stark detail what might happen if one day the world decided to decommission all its oil tankers, rigs, pipelines and strategic reserves. The authors, environmental scientist Steve Hallett and journalist John Wright, expect that we’d initially see sky-high prices and long lines at pumps. After a few weeks, fuel wouldn’t be had at any price and even first-world citizens would struggle to stay fed and out of the elements. This is no Hollywood doomsday scenario—it’s a levelheaded extrapolation from current trends in the fast deteriorating world energy situation.

The roads to our alternative energy future

by

How fast do we need to transition off of fossil fuels? What industrial capacity is available today for different alternative energy technologies and what is likely to be available in the future? What might we do if we can’t replace fossil fuels with alternatives fast enough, and what might the consequences be? I finally got around to re-doing these calculations, and wanted to go through the numbers.

Renewable energy zealots must understand ‘Net Energy’

by

Was I surprised that last issue’s column, Can Renewables Outshine Fossil Fuels?, elicited a strong reaction, with written responses of support and derision? Not at all. It’s an issue that continues to divide the environmental community, and one which keeps us from moving forward as quickly as possible to conserve resources and relocalize as an era of cheap, concentrated, easy-to-get energy comes to an end.

When oil and gas are depleted

by

In this year, 2011, we are enjoying a lifestyle beyond the most optimistic dreams of past generations. We are benefitting from the whirlwind of achievements in science and technology during the last hundred years. There has never been a century like the one just passed, and there will never be another like it. Lifestyles will be very different when oil and gas are depleted.

Less heat, more light on peak oil

by

“Because money talks and BS walks, if the hydrogen economy was an apprentice working for Donald Trump, it would’ve been fired in the first season.” This is just one of the pearls of wisdom from Transition Voice’s new “Snarky Guide to Peak Oil.” It’s got the facts you need to debunk energy myths and the attitude you need to defuse a heated discussion with a smile.
