Categories: Peak Oil/Gas & Energy Demand, Renewable Energy Sources

Talks by Jim Hansen and Charlie HallIndependent financial consultant Jim Hansen runs every investment through the "peak oil test". In this presentation from the ASPO-USA 2008 conference, he explores traditional energy investments; opportunities in renewables, rail, and electrifying the transportation system; areas to avoid like airlines and trucking; and what to watch, like electric cars and the unwinding of globalization.

In this interview, ecologist and professor Charlie Hall looks at energy return on energy invested. Whether it's a cheetah chasing antelope, or humans making ethanol — the energy we get back has to exceed the energy we put in, or the story is over. He compares oil's energy return in the 1930's (1 calorie invested returned 100 calories of energy) with the current situation (1:12) and still declining.

Presenters respond to the final question in the Q&A session at the close of ASPO-USA's 2008 conference: how do we better harness the intellect, energy and commitment at this conference, and what one thing would you have people ask an elected official to do about peak oil?

About author/contributor Member: PT (David Alexander) PT (David Alexander)
   Web site: http://www.insightandenergy.com

Member: PT (David Alexander) My lifelong pursuit, since age 18, has been to live more fully and find wisdom. This has involved studies with Zen masters, Tai Chi masters, and great psychotherapists while achieving my license as a gestalt therapist and psychoanalyst.

Along the way, I became aware of how the planet is under great stress due to the driven nature of human activity on this planet.

I believe that the advancement of human well-being will reduce societies addictive behaviors, and will thus also help preserve the environment and perhaps slow down the effects of global warming and other major threats to the health of human societies.
