Sorry about the ad below if there is one and sorry about the fact that the spent fuel pool might blow over in the typhoon and make the northern hemisphere uninhabitable.



Air pollution and early deaths in the United States

Via MIT. Looking at 2005:

… Total combustion emissions in the U.S. account for about 200,000 (90% CI: 90,000–362,000) premature deaths per year in the U.S. due to changes in PM2.5 concentrations, and about 10,000 (90% CI: −1000 to 21,000) deaths due to changes in ozone concentrations. The largest contributors for both pollutant-related mortalities are road transportation, causing ∼53,000 (90% CI: 24,000–95,000) PM2.5-related deaths and ∼5000 (90% CI: −900 to 11,000) ozone-related early deaths per year, and power generation, causing ∼52,000 (90% CI: 23,000–94,000) PM2.5-related and ∼2000 (90% CI: −300 to 4000) ozone-related premature mortalities per year. Industrial emissions contribute to ∼41,000 (90% CI: 18,000–74,000) early deaths from PM2.5 and ∼2000 (90% CI: 0–4000) early deaths from ozone. The results are indicative of the extent to which policy measures could be undertaken in order to mitigate the impact of specific emissions from different sectors — in particular black carbon emissions from road transportation and sulfur dioxide emissions from power generation.

Impact of the federal government shutdown on EIA ›

As a result of the lapse in appropriations for the U.S. Energy Information Administration, the EIA.gov website and our social media channels will not be updated after 1:00 p.m. Eastern Time on Friday, October 11, 2013. Transactions submitted via the website might not be processed until appropriations are enacted; databases might not be available; and we will not be able to respond to inquiries.

Will the shutdown affect EIA\’s reports and data releases? Yes. The release of all reports and data will cease during the shutdown.

Butane

Blending butane into gasoline is why gas prices fall in the fall, according to Robert Rapier. RVP = Reid vapor pressure, the higher the RVP the faster the evaporation. EPA sets limits on RVP of gasoline which are more stringent in summer months than in winter, allowing the increased blending of cheap, yet highly evaporative (word?) butane:

Butane has an RVP of 52 psi, which means pure butane is a gas at normal pressures and temperatures. But butane can be blended into gasoline, and its fractional contribution to the blend roughly determines its fractional contribution to the overall vapor pressure of the mixture. As long as the vapor pressure of the total blend does not exceed normal atmospheric pressure (again, ~14.7 psi) then butane can exist as a liquid component in a gasoline blend.

But with a vapor pressure as high as 52 psi, butane can’t make a large contribution to summer blends where the vapor pressure limit is 7.8 psi. For example, if a gasoline blend contained 10 percent butane, butane’s contribution to the vapor pressure limit is already 5.2 psi and you would still have 90 percent of the blend to go. It isn’t feasible to blend much butane into gasoline when the vapor pressure requirement is low. But when the limit increases by 5 or 7 psi, it becomes feasible to blend large quantities of butane.

Why do we care about blending butane anyway? Because it is abundant and cheap. Butane can routinely trade at a $1/gallon discount to crude oil or gasoline. Butane is a byproduct of oil refining, but is also a component of natural gas liquids (NGLs), which are condensed out during natural gas production. Given the huge expansion of natural gas production in the US, it should come as no surprise that NGL production is also on the rise.

According to an excerpt from a new book, Sheryl Crow witnessed Lance Armstrong receive a blood transfusion in 2004 and told federal investigators about in 2011.
