[Editor note: Some important facts are emphasized in this post: the Gulf oil spill occurred on property owned and managed by the federal government, and the operator-at-fault (BP) has been the most politically active in its industry.

With some 7,000 barrels of oil spilling into the Gulf of Mexico each day from BP’s exploded Deepwater Horizon well, offshore drilling and oil-industry regulation have returned to the front pages.
The familiar old trap is set: Do you want unfettered markets and oil spills or government regulation and safety? The implied premise is that the oil industry operates in a free market. So, the argument goes, the only alternative is government regulation.
On first glance that story is plausible.…

Part I introduced the issues. Part II showed negated emission savings for the Netherlands at current wind penetration (about 3 percent). Part III extended the Netherland’s experience to the higher wind penetration in Colorado (6%) which demonstrates higher emissions. Part IV concludes with the Bentek results for Texas,which confirms those for Colorado.]
There are a number of relevant, notable characteristics of the 2008 Texas electricity production profile, 85% of which is managed by ERCOT:
[Editor’s note: This is the third of four posts on (elevated) fossil-fuel emissions associated with firming otherwise intermittent wind power. Part I introduced the issues. Part II showed negated emission savings for the Netherlands at current wind penetration (about 3 percent). Part III (below) and Part IV tommorow examine the higher emissions from wind in Colorado and Texas, respectively, according to a new study by Bentek.]
The Bentek study is a significant contribution to the wind/fossil-fuel emission literature despite some notable limitations. The study analyzes the PSCO system, which dominates Colorado’s needs, and the ERCOT system in Texas, which manages 85% of that state’s electricity.
The analysis includes SO2, NOx and CO2 emissions. Bentek looks at coal cycling events only in both cases, ignoring any gas cycling, while noting PSCO’s acknowledgement that wind impacts gas as well as coal.…
