My initial post, “Wind Integration: Incremental Emissions from Back-Up Generation Cycling: (Part I: A Framework and Calculator),” provided an overview of a fossil fuel and CO2 emissions calculator. It showed that industrial wind plants do not provide the claimed reductions in these important areas, which brings into question their value as good public policy.

This post provides some background, a base case and the results of taking necessary additional considerations into account. The base case has two scenarios.

The first is that every MWh of wind production directly reduces the full fossil fuel consumption and CO2 emissions for every MWh of the “displaced” fossil fuel plant, which is a very simplistic view.  The second takes some limited considerations into account, which can show that as much of 85 percent of the simplistic-view savings are still achieved.…

Editor note: Mr. Hawkins’ study is presented to increase the interest in this highly important,  politically sensitive issue of incremental pollution from firming up industrial wind power. This post has been joined by Parts II-V, with Part V providing updates to the calculator and links to the other posts.

Integrating random, highly variable wind energy into an electricity system presents substantial problems that subvert wind technology’s ability to offset the use of fossil fuels–and avoid air emissions, including carbon dioxide (CO2). Measuring this accurately is important because many believe that wind projects significantly reduce such emissions.

This analysis finds that natural gas used as wind back-up in place of baseload or intermediate gas (in the absence of wind) results in approximately the same gas burn and an increase in related emissions, including CO2.…

The latest peak oil news is simply astounding: a whistleblower inside the International Energy Agency (IEA) claiming that “the US has played an influential role in encouraging the watchdog to underplay the rate of decline from existing oil fields while overplaying the chances of finding new reserves.”

The fact that this report appeared in the Guardian, which has published questionable articles on peak oil, is suggestive.

First and foremost, one is tempted to conclude that this story represents poor reporting, bringing to mind an earlier Guardian story claiming that Fatih Birol, the IEA official in charge of the World Energy Outlook, acknowledged peak oil. It turns out that Fatih was misquoted. And while I might be biased, considering Fatih a friend, the nature of the present story is close to ridiculous, rather than misleading.…

This article, “Energy to Spare” by David Warren, published in the Ottawa Citizen on November 4, 2009, says much in few words. Energy reality is that the sun’s work over the ages has produced energy sources (oil, gas, and coal) that far exceed the dilute energy from the sun. The stock beats the flow–by a country mile.

This article is reproduced below as a Weekend reading feature:

Will technology solve our energy problems? This seemingly fatuous question is actually stupider than first appears. For we already have the technology to power anything within reason, with minimal if any environmental fallout.

Yet under the inspiration of the Green Zeitgeist, I cannot go into a magazine shop without finding some science-lite cover story on new prospects for harnessing solar, thermal, wind, tidal, or whatever “renewable” forces.…
