The seemingly most reliable information on EROI is quite old and is summarized in chapter 12 of Hall et al. (1986). Newer information tends to fall into the wildly optimistic camp (high EROI, e.g. 10:1 or more, sometimes wildly more) or the extremely pessimistic (low or even negative EROI) camp (Tyner et al. 1998, Tyner 2002, Fleay 2006 and Caldicamp 2006). One recent PhD analysis from Sweden undertook an emergy analysis (a kind of comprehensive energy analysis including all environmental inputs and quality corrections as per Howard Odum) and found an emergy return on emergy invested of 11:1 (with a high quality factor for electricity) but it was not possible to undertake an energy analysis from the data presented (Kindburg, 2007). Nevertheless that final number is similar to many of the older analyses when a quality correction is included.

Tyner was the author (or co-author) on the 1988 and 1997 reports which are examples of the lower EROI numbers -- less than 5:1. Tyner’s 1997 paper reported an “optimistic value” of 3.84 and a “less-optimistic” value of 1.86 and may be based on “pessimistic” cost estimates.

DOE study says wind farms don't hurt property value - Business | Tri-City Herald : Mid-... - 0 views
-
Wind farms have no measurable effect on nearby property values, according to a government report published Wednesday. In the latest study, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory spent three years examining nearly 7,500 sales of homes in 10 communities near two dozen wind farms in nine states. The findings, however, are unlikely to cool the debate over the placement of massive wind turbines which to some represent progress, but to others an intrusion. Questions about the integrity of the $500,000 Berkeley study were aired even before the report was released.

New NRG nuclear plant to cost $10 billion | Reuters - 0 views

The cost to build a new nuclear power plant in Texas has risen to $10 billion, up from early estimates, but much below price tags of other proposed U.S. nuclear projects, an executive with NRG Energy Inc's nuclear development arm said on Tuesday. The "all in" cost to build two 1,350-megawatt nuclear reactors in South Texas has risen 40 percent from 2006 estimates which did not include financing costs, Steve Winn, chief executive of Nuclear Innovation North America (NINA), told the Reuters Global Energy Summit. While higher, NINA's current estimate is more than $10 billion under estimates from other nuclear developers that operate in states where regulators determine how much money utilities can charge customers for new power plants.
Report looks at hidden health costs of energy production - Politics AP - MiamiHerald.com - 0 views
-
Generating electricity by burning coal is responsible for about half of an estimated $120 billion in yearly costs from early deaths and health damages to thousands of Americans from the use of fossil fuels, a federal advisory group said Monday. A one-year study by the National Research Council looked at many costs of energy production and the use of fossil fuels that aren't reflected in the price of energy. The $120 billion sum was the cost to human health from U.S. electricity production, transportation and heating in 2005, the latest year with full data. The report also looks at other hidden costs from climate change, hazardous air pollutants such as mercury, harm to ecosystems and risks to national security, but it doesn't put a dollar value on them.
