R-Squared Energy TV: Episode 6 – EROEI Explained

In this week’s episode of R-Squared Energy TV I present the first of several mini-presentations on energy topics of interest. The presentations will be short, 5 to 8 minute presentations with 3 to 5 slides each. This week’s presentation is on Energy Return on Energy Invested (EROEI). I believe there are a lot of misunderstandings from both proponents and opponents of EROEI methodology, and I attempt to clear up some of the misconceptions. Some of the questions answered are:

• What exactly is EROEI?
• Where might it be useful, and where might it possibly provide misleading answers?
• What are the societal implications of a declining EROEI?
• When is a lower EROEI process better than a higher EROEI process?
• What does EROEI suggest about the economics of a process?

Readers who have specific questions can send them to ask [at] consumerenergyreport [dot] com or leave the question after this post (at the original source). Consider subscribing to our YouTube channel where you’ll be able to view past and future videos.
