A series of photos presented by National Geographic shows the rapid expansion… (National Geographic ) The tar sand mines in Alberta, source of the oil that may one day flow all the way from Canada to Texas through the Keystone XL Pipeline, are growing by enormous leaps and bounds. This superb series of satellite pictures , brought to you by National Geographic , tells the whole story. When the first mine opened alongside the pristine Athabasca River in 1967, oil extracted from oil sands (also known as tar sands) was too expensive to compete with liquid crude. But now, with oil prices hovering at about $100 US per barrel, the costly and environmentally taxing process of pulling bitumen out of the clay mixture makes it economically feasible. Processing, transporting and refining the oil is very energy intensive, however, producing 15% to 80% more carbon emissions than average petroleum products over their life cycle.

A new study released Wednesday said that the regulatory fallout from the Fukushima power plant disaster in Japan in March will short-circuit the U.S. nuclear renaissance of new power plant construction. The report, "Nuclear Safety and Nuclear Economics," was written and presented by Mark Cooper, a frequent critic of the nuclear power industry. The report can be found here . Cooper is a senior fellow for economic analysis at the Institute for Energy and the Environment at the Vermont Law School. Cooper said that past nuclear disasters, such as the one at the Three Mile Island power plant in Pennsylvania in 1979, have tended to greatly raise regulatory barriers and have also severely multiplied the cost of reactor construction. After Three Mile Island, for example, the report said, the cost of nuclear power plant construction doubled in most cases and trebled or quadrupled in some rare instances.

(Natural News) There has been a lot of disinformation regarding the Fukushima Nuclear disaster. It appears the government agencies of other nations cooperated with Japan while the international nuclear industry sided with TEPCO's (Tokyo Electric Power Company) disinformation and denial campaign. As Mike Adams noted in his April 5th, 2011 Natural News article on Fukushima, "The government is going to turn off the radiation detectors, raise the official EPA limits of radioactive exposure, urge Americans to avoid preparing for fallout, and then pretend absolutely nothing is wrong." Understanding the Millisievert Millisievert figures are tossed out by the media with little attention to explaining them. Millisieverts (mSv) are measurements of ionizing radiation absorbed by a human body.
