Geothermal

The alternative energy matrix

Tom Murphy, Do the Math

Breathe, Neo. I’ve been running a marathon lately to cover all the major players that may provide viable alternatives to fossil fuels this century. Even though I have not exhausted all possibilities, or covered each topic exhaustively, I am exhausted. So in this post, I will provide a recap of all the schemes discussed thus far, in matrix form. Then Do the Math will shift its focus to more of the “what next” part of the message.

Warm and fuzzy on geothermal?

Tom Murphy, Do the Math

The Earth started its existence as a red-hot rock, and has been cooling ever since. It’s still quite toasty in the core, and will remain so for billions of years, yet. Cooling implies a flow of heat, and where heat flows, the possibility exists of capturing useful energy. Geysers and volcanoes are obvious manifestations of geothermal energy, but what role can it play toward satisfying our current global demand? Following the recent theme of Do the Math, we will put geothermal in one of three boxes labeled abundant, potent, or niche (puny). Have any guesses?

Review: Life Without Oil by Steve Hallett With John Wright

Frank Kaminski, Mud City Press

“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. [An essay prefiguring the book originally appeared in The Washington Post.]

The roads to our alternative energy future

Barath Raghavan, contraposition

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'

Megan Quinn Bachman, Ecowatch Journal

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.

As nuclear falters, here is a practical, affordable (and safe) clean electricity plan

Craig A. Severance, Energy Economy Online

In the wake of the Japanese nuclear debacle, we need a practical and affordable clean electricity plan that does not rely on new nuclear power. This article presents just such a Plan. New nuclear is absent from the Plan not because of any safety concern, but simply because it fails the "practical and affordable" test. President Obama called for "80% Clean Energy" by 2035. This Plan presents how we can do it right.

What works: 98.6 degrees

Guy R. McPherson, Nature Bats Last

I invested a lot of time into finding our post-carbon landing pad. I tend to side with realtors on this one: location, location, location.

Energy concentration revisited

John Michael Greer, The Archdruid Report

The difference between diffuse and concentrated energy sources, the theme of last week's Archdruid Report post, means that some of today's highly touted alternative energy schemes may be worth much less than currently claimed, while other technologies that receive much less attention may be the wave of the future. A closer consideration of energy concentration and its effects helps clarify which is which.

Job Losses Push Need for Energy Bill

Craig A. Severance CPA, Energy Economy Online

Millions of job losses are pushing the U.S. Senate to consider a Jobs and Energy bill, even though Cap and Trade appears to be on life support. What are Five Key Measures that must be in a new Bill to avoid being a "half-ass..d" effort? (term from Sen. Lindsey Graham descrbing limited climate bill)

Resources and anthropocentrism

Guy R. McPherson, Nature Bats Last

Evolution demands short-term thinking focused on individual survival. Most attempts to overcome our evolutionarily hardwired absorption with self are selected against. The Overman is dead, killed by a high-fat diet and unwillingness to exercise. Reflexively, we follow him into the grave.
