Fossil Fuels

Tom Murphy Interview: Resource depletion is a bigger threat than climate change

by

Rising geopolitical tensions and high oil prices are continuing to help renewable energy find favour amongst investors and politicians. Yet how much faith should we place in renewables to make up the shortfall in fossil fuels? Can science really solve our energy problems, and which sectors offers the best hope for our energy future? To help us get to the bottom of this we spoke with energy specialist Dr. Tom Murphy, an associate professor of physics at the University of California. Tom runs the popular energy blog Do the Math which takes an astrophysicist’s-eye view of societal issues relating to energy production, climate change, and economic growth.

If only we had free energy

by

I thought I’d do a thought experiment. Suppose tomorrow morning a hypothetical university—let’s call it T.I.M.—sends out their weekly press release claiming a “revolutionary breakthrough” that will change the way we think about energy. Unlike every other time in the past decade they’ve made this claim, though, suppose this time it’s actually true: they’ve discovered a way of producing extremely cheap energy—as near to “free energy” as can be imagined.

The Peak Oil Crisis: Parsing the Bakken

by

As we have seen with the Bakken and the various natural gas bearing shales we have been drilling of late, it takes an awful lot of expensive wells and environmental disruption to get the oil out. One estimate of the Energy Returned on Energy Investment (EROEI) for the Bakken shale suggests that the EROEI is six. This means that it may take one oil barrel’s worth of energy to produce six barrels of Bakken shale oil. This is getting very close to the theoretical point at which it really is not worth the effort and all the economic disruption.

The aspect of this “energy independence” story that the optimists continue to ignore is that, while oil production from shale may be climbing, depletion of our other sources of oil continues apace

Fun with Trends

by
If current energy trends continue . . .
  • By 2015 China will be importing more oil than the United States does that year.
  • By 2030 China will be absorbing all available global oil exports, leaving none for the US or Europe.
  • In just 8 years China will be burning as much coal as the entire world uses today.
  • Natural gas will be virtually free in the US by 2015.
  • Officially assessed US natural gas reserves will be exhausted by 2025.

Why won’t Obama mention peak oil? Blame Rush Limbaugh

by

I believe that Obama understands peak oil and for years I’ve been hoping that he would finally take leadership on energy. But if Ezra Klein is right, then even if Obama were a card carrying member of ASPO-USA, in today’s partisan hell, the most powerful man on Earth might be nearly helpless to make any difference on peak oil.

Commentary: I. Collapse? Really?

by

Collapse is a scary word, and some people doubt it is even relevant to us. Obviously we are facing some major challenges in this century. Does that mean collapse? What is collapse, exactly? When societies have collapsed, what actually happened? How bad is it? Are there ways of reducing the badness? While historic events can’t give a totally accurate picture of the future, they can at least give us some ground to stand on.
