On Tuesday, we published a story on the near impossible task of reaching energy independence. Our friends at PRI’s The World simultaneously aired a story that answers questions on why tapping new sources of fossil fuels won’t help the U.S., or any country, get off the treadmill. The answer? It’s a lot more energy intensive to produce a gallon of gas today, than it was 100 years ago. The World has more:
Getting a barrel of oil out of the ground takes energy. Years ago, you could get 100 barrels of oil out of the ground with just one barrel of oil spent. Now, it’s more like 20 to one, or even five to one. That compares favorably with renewable energy sources — but it all depends on how things are counted.
The World breaks down the meaning of the Energy Return on Investment, or EROI, and compares the costs of producing fossil fuels to renewables.
