Relevance | DateW. S. Jevons and UK Coal Revisited (worth re-reading weekend)
By Robert Bradley Jr. -- June 20, 2009 No CommentsIn an earlier post at MasterResource, W. S. Jevons (1865) on Coal (Memo to Obama, Part III), the hall-of-fame-economist explained how coal was a godsend to Britain, powering the industrial revolution in a way that renewable energies could not.
I am reminded of Jevons with the headline from the June 17th Guardian, “Carbon capture plans threaten shutdown of all UK coal-fired power stations.” It read in part:
… Continue ReadingAll of Britain’s coal-fired power stations, including Drax, the country’s largest emitter of carbon, could be forced to close down under radical plans unveiled by government today. Ed Miliband, the energy secretary, is proposing to extend his plans to force companies to fit carbon capture and storage technology (CCS) onto new coal plants – as revealed by the Guardian – to cover a dozen existing coal plants.
Is Rail Really a Fuel Saver? (rethinking a rationale for Obama’s National Transportation Plan)

Amtrak, the American Public Transportation Association, and other passenger-rail advocates want everyone to believe that passenger trains are more energy efficient than driving. This helps them justify the hundreds of billions of tax subsidies they receive. But is this rationale true?
Comparing the Studies
A new study from the University of California (Davis) finds that the answer depends on such things as load factors: your auto carrying four people consumes a lot less energy per passenger mile than a subway (which on average is only one-sixth full) or Amtrak train (which on average is only half full).
The Department of Energy’s Transportation Energy Data Book says that, on average, cars consumed…

By Marlo Lewis -- May 4, 2009 10 CommentsOne dumb government intervention in energy markets typically begets another, as special interests lobby to counteract the unintended (although not unforeseen) consequences of some previous intervention they championed. The federal ethanol mandate, also known as the renewable fuel standard (RFS), provides a recent example.
Thanks to this Soviet-style production quota system, which Congress created in 2005 and expanded in 2007, daily corn ethanol production in February increased by about 17,000 barrels to 647,000 barrels per day, despite weak motor-fuel demand and poor to negative profit margins for ethanol producers.
Unsurprisingly, inventories of unsold ethanol increased by 1.5 million barrels in February and about 20% of new capacity added last year is idle. An ethanol glut is one of the factors that have bankrupted several ethanol companies. Other factors include high feedstock (corn) prices in 2008–itself a consequence of the mandate—and the collapse of crude oil and gasoline prices in 2009.…

Energy Myths and Realities
There may be no greater challenge facing mankind today – and your generation in particular – than figuring out how we’re going to meet the energy needs of a planet that may have 9 billion people living on it by the middle of this century. The magnitude of that challenge becomes even more daunting when you consider that of the 6.5 billion people on the planet today, nearly two billion people don’t even have electricity – never flipped a light switch.
False 1970s Consensus
Now, the “consensus” back in the mid-1970s was that America and the world were running out of oil.…
