Below is a summary of my presentation, The Renewables Gap, from the ASPO 2009 conference. The intent of my presentation was to highlight the political challenge of affecting a societal transition to renewable sources of energy. In particular, I focus on wind and solar, though it seems to me that the problem will be largely the same (if not worse) if we attempt to rely on other “renewables.” My initial presentation focused on attempting to illustrate the Renewables Gap as an energy problem. While I briefly addressed the political aspects of this problem in my presentation, on reflection I’ve chosen to focus more carefully on this aspect of the Renewables Gap.
Frankly, I've never been very pessimistic about our theoretical ability to adapt to peak oil. It’s what I fear we will actually do in response—or, rather, what we won’t do—that concerns me. I feel the same way about our ability to transition to alternative sources of energy—the challenge that I’ve termed the Renewables Gap. I’m quite confident that we have the theoretical ability to deal with the problem. However, if you accept that “politics” is the process of allocating scarce resources in a society, then it is the political problem posed that appears most daunting. Like many things involving peak oil, we’re sure to have all the political will that we need to deal with the problem at only some point after our window of opportunity to act has closed. The challenge is figuring out how to spread awareness of the nature of the problem and willingness to commit scarce resources to its solution before there is a crisis. Here, again, my pessimism is grounded in what I fear we will not do. I don’t pretend to offer any easy solution (the desire for which gives much insight into the nature of this very problem). My goal here is only to provide a framework for thinking about this problem:
Renewable Transition 2: EROEI Uncertainty

In the first part of this series, I discussed the practicality of a future transition from fossil fuels to renewable energy sources—specifically renewable sources of electricity such as solar and wind power. One little-discussed hurdle is the fact that, because we must invest energy in renewables up front, a rapid transition threatens to greatly impact near-term demand for energy resulting in unwanted economic and political effects. Another is that, because we will initially use fossil fuels to build our renewable infrastructure, the transition to renewables will result in a short-term increase in carbon emissions. The extent to which both of these impacts will be significant, even their potential to foreclose the possibility of such a transition, will turn on the net energy, or Energy Return on Energy Invested (EROEI), of available renewable energy technology.
As I alluded to last time, while there are many EROEI numbers floating about for solar, wind, etc., these numbers are far less accurate or verifiable than is, I believe, commonly assumed. I’ll argue that our measurements of EROEI are fundamentally flawed, at least for some purposes. Most EROEI studies serve as a tool to compare different technologies or to gauge advances in technology--a role for which they are generally well suited. However, when viewed from a complete systems perspective, current EROEI figures fail to provide an inclusive measurement. I’ll argue that, for purposes of planning a civilizational transition, a meaningful meansure must be inclusive of all energy inputs. Finally, I’ll propose a possible proxy-measurement to address the methodological issues surrounding EROEI.
