“Thorium-Fueled Automobile Engine Needs Refueling Once a Century,” reads the headline of an October 2013 story in an online trade publication. This fantastic promise is just one part of a modern boomlet in enthusiasm about the energy potential of thorium, a radioactive element that is far more abundant than uranium. Thorium promoters consistently extol its supposed advantages over uranium.
Pretty interesting article discussing the balance of the world's oil supply and how declining OPEC oil has led to default carbon emission caps. "Despite all the frenzy about a North American oil boom, non-OPEC crude oil production is not actually going up, because new production is roughly balancing declines at existing oil fields. Policy makers, analysts, and the news media alike have failed to recognize that, given this production reality, OPEC still controls not only the final total global oil supply but also oil pricing. In fact, the organization has been raising oil prices and reducing demand for oil since 2003, and this demand constriction has also greatly reduced greenhouse gas emissions."
President Obama's climate change speech went pretty far out of its way to explicitly say that what he's trying to do is get the United States to burn less coal, but that didn't stop coal-fired politicians like Sen.
Although reducing emissions of carbon dioxide is essential if climate change is to be slowed and then halted in the long run, researchers are analyzing a number of alternative pathways for reducing human-related forcing on climate over the next few...
Nice explanation on why HFCs are actually as bad, if not worse, than carbon dioxide and why international agreement on limiting them is essential.
On April 26, 1986, technicians at Unit 4 in Chernobyl, Ukraine, were conducting a test of their RBMK nuclear reactor when they inadvertently started a runaway reaction. Excess, superheated steam built up, the core was blasted open, and a huge plume of radioactive material wafted into the sky. The heat was so intense that it caused the nuclear fuel still in the plant to liquefy, where it mixed with other materials, such as concrete, and formed a lava-like material that flowed into the spaces below.
All energy sources have benefits, costs, and risks. Nuclear reactors, among the largest power plants on Earth, do not produce greenhouse gas emissions, and nuclear energy has an overall low public-risk curve.
Excellent, thorough article by Lake Barrett, retired nuclear engineer and former director of the NRC's Three Mile Island Cleanup Site Office.
The abandonment of aging nuclear reactors—most prominently reactors that need repairs, as is the case at San Onofre in California and Crystal River in Florida, but also at some plants that have simply become uneconomic to operate,...has huge implications for resource-acquisition decisions."
This is an excellent article explaining some of the problems with nuclear energy (even the new technology) that is largely ignored by pro-nuclear advocates. Some environmentalists are now supporting nuclear power as a way to combat climate change (see Pandora's Promise), but the information presented in this article should not be ignored.
