| Where Has the Oil Gone? Oil supply is not infinite. Sooner or later it will run out. The interesting speculation is when that will happen. In a recent publication (ACS Energy and Fuels), several Kuwait scientists have studied this matter with a multicycle Hubbert model. The original Hubbert model in 1956, accurately predicted that oil production would peak in the United States around 1970. The model has since gained in popularity and has been used to forecast oil production worldwide. However, recent studies show that the model does not take into account more complex oil production cycles of some countries. Those cycles can be heavily influenced by technology changes, politics, social upheavals, and other factors. |
| Green Cleaning Supplies When we get out the rags and the wash buckets, we have the best of intentions. Cleanliness is a virtue, right? And healthy too! Well, if you use conventional cleaning products, perhaps not. Have you ever cleaned your shower or oven and then had teary eyes, burning nasal tissues, an itchy throat, a headache, or dizziness? Guess what? All of these symptoms and more could have been caused by chemicals commonly found in household cleaners. |
| Global Trade’s Dirty Secret: Outsourced Emissions The Carnegie Institution of Science released a new study this week finding that one-third of the carbon dioxide emissions developed countries release into the atmosphere result from goods and services produced outside their borders. The report’s details are troubling: Carnegie’s researchers estimate that 2.5 tons of CO2 per person are consumed in the United States but are produced elsewhere, and that figure spikes to 4 tons per European. Another point that will cause considerable disagreement among global climate negotiators is Carnegie’s analysis that one-quarter of the emissions in China are actually the result of its exports to its trading partners such as the United States. |
| US EPA to regulate Green House gas emissions from cars The White House is finalizing rules on the first U.S. greenhouse gas emission standard for automobiles, which would raise average fuel economy 42 percent by 2016 in a bid to slash oil imports and fight climate change. The Environmental Protection Agency and the Transportation Department sent the final rules this week to the White House's Office of Management and Budget, according to a notice posted on the OMB website. The higher mileage requirements will reduce U.S. greenhouse gas emissions by 900 million metric tons and save 1.8 billion barrels of oil over the life of vehicles built during the 2012-2016 model years, according to the EPA. |
