Index / Climate Change, Anthropocene & Associated Issues

Dr. Conca says we need to institute a Clean Energy Standard that promotes all low-carbon energy rather than continuing with a Renewable Energy Standard that is narrowly-focused on wind and solar. If you care about climate change, and do not just have an ideological (aka political) stand on a particular energy source, then we need all low-carbon sources as fast as possible to have any hope of reigning in the most adverse environmental effects of burning fossil fuels.

Along with an increasing abundance of gas, coal and oil, the present focus on renewables has stalled the effort to low... More →

Index / Uranium (Nuclear Minerals) / Nuclear Power - Economics, Design, and Industry

Eduardo Porter, of the NY Times, asks the question ... Is the global effort to combat climate change, painstakingly agreed to in Paris seven months ago, already going off the rails? He reports that Germany, Europe champion for renewable energy, seems to be having second thoughts about its ambitious push to ramp up its use of renewable fuels for power generation (in place of their existing nuclear power).

Hoping to slow the burst of new renewable energy on its grid, the country eliminated an open-ended subsidy for solar and wind power and put a ceiling on additional renewable capacit... More →

Index / Renewable Energy (Other Energy Resources) / Economics, Batteries

Teresa Matich reports that lithium batteries may reign supreme when it comes to cellphones, laptops and electric vehicles. But for larger-scale energy storage, some are looking at alternative metals and technologies. Enter Vanadium redox batteries.

First successfully created by Dr. Maria Skyllas-Kazacos of the University of New South Wales in the 1980s, Vanadium redox flow batteries use sulfuric solutions to power themselves. A vanadium electrolyte passing through a proton exchange membrane allows the battery to work, with a solution filling two tanks on either side. Unlike other b... More →

Index / Uranium (Nuclear Minerals) / Exploration, Mining, Marketing, Acquisitions

Kristen Moran reports that uranium in the U.S. is used primarily for nuclear power. However, uranium mining originally had its roots in the production of uranium-bearing ore in 1898. At that time, sandstone material on the Colorado Plateau in Colorado and Utah was mined for its vanadium content.

In the 1950s, the U.S. encouraged a great deal of uranium mining. This was promoted by federal subsidies and rising global demand largely driven by nuclear weapons procurement programs. The trend lasted until the early 1980s, when changing geopolitical circumstances as well as safety, enviro... More →

Index / Uranium (Nuclear Minerals) / Nuclear Power - Economics, Design, and Industry

Rob Nikolewski writes about wind and solar but opines on nuclear. The scientists and engineers at General Atomics think the future of nuclear energy is coming on the back of a flatbed truck. And the leadership at the San Diego-based company, which has been developing nuclear technologies for more than 60 years, has already spent millions in the expectation that its plans for the next generation of reactors will actually work(?).

We have technology that we think is going to qualitatively change the game, said Christina Back, vice president of nuclear technologies and materials at Gen... More →

Ronald Kovach reports that even though those major hacks did not involve building controls, that is not to say there is not evidence of such intrusions. According to the GAO, the number of cyber incidents involving industrial control systems (in this case, including building and access controls) that were reported to the Depart. of Homeland Security increased 74% from 2011 to 2014, with 245 incidents reported in 2014. Many more incidents occur in critical infrastructure that go unreported, DHS says.

Index / Solar Energy / Economics

Solar electricity production in California falls into two categories ... solar thermal, using the concentrated heat of sunlight to heat a fluid to make steam to turn a traditional turbine and generator making electricity, and solar photovoltaic (PV), the direct conversion of sunlight into electricity. Additionally, the heat from the sun is used in solar thermal systems for hot water in homes and businesses and in heating swimming pools. Most electricity from PV is not counted into the total electricity production of the utility companies as the solar panels are mounted on individual homes or b... More →

Ken Silverstein reports that when the 3 amigos met in Canada, they had vowed to collectively produce half of all their electricity from clean power sources. But what the leaders of the U.S., Canada and Mexico did not plan on was that their joint announcement would coincide with the closure of a major nuclear plant in California, which has become the clean energy capital of the world.

It is ironic and begs the question of why the traditional environmental movement is so vehemently opposed to nuclear energy, especially since it is the only fuel that can burn around the clock without r... More →

Dr. Conca reports that a widespread claim ... that dozens of nuclear plants merit subsidies to protect the climate of the Earth, has been borne out by reality. One of the U.S. most prominent and technically capable utilities, Pacific Gas & Electric Company, recently announced its decision to close its well-running, low-carbon, low-cost nuclear reactors at Diablo Canyon, because of political pressure from the state of California and especially from its Lt. Governor. At the same time, tax subsidies for renewables, plus low natural gas prices, are making reactors uneconomic in the short term.... More →

John Schwartz, of the NY Times, opines that by just about any measure, the movement to battle climate change has grown so large that the truths of the Al Gore decade-old movie now seem more mainstream than inconvenient. In Paris, 195 nations agreed to reduce greenhouse gases. In the U.S., 70% of Americans say that climate change is real. Pope Francis has joined the call for action. Hundreds of thousands of people have come together for climate marches in Paris and New York, and demonstrators recently held fossil-fuel protests on six continents.

Jack Fitzpatrick reports that Democrats complained Thursday about a House Energy and Commerce subcommittee hearing about creating a proposed nuclear waste facility at Nevada Yucca Mountain, saying it was a waste of time to discuss a proposal that has little local support and is not going anywhere. Some Nevada Republicans, meanwhile, indicated a tepid willingness to negotiate.

Rep. Dina Titus (D-Nev.), who testified as a witness, lambasted the proposal and called promises of extra infrastructure funding a bribe. She allowed that they cannot and will not be bought off Titus.

William Levis opines that the U.S. nuclear plants are at risk. In 2013, the U.S. had 104 operating nuclear plants. Since then, a dozen have closed or announced plans to shut down. These productive nuclear plants are not closing because they are too old or unsafe, but rather for economic reasons. If we do not act, and nuclear plants continue to close, the consequences will be significant for the economy, for customers, and for the environment.

Index / Uranium (Nuclear Minerals) / Nuclear Power - Economics, Design, and Industry

Joe Romm opines that climatologist James Hansen argued last month that nuclear power paves the only viable path forward on climate change. Romm claims he is wrong. As the NEA and IEA explained in a major report last year, in the best-case scenario, nuclear power can play a modest, but important, role in avoiding catastrophic global warming if it can solve its various nagging problems, particularly high-construction cost, without sacrificing safety.

Hansen and other climate scientists Romm respect, e.g., Ken Caldeira, Tom Wigley, and Kerry Emanuel, present a weak argument in which ne... More →

Dr. Conca reports that as we head into the hottest part of summer in the Northern Hemisphere, in what could be the hottest year on record, we barely give a thought to what using air conditioning does to our electricity grid. And what it will do to a hotter world in the future.

According to a recent Department of Energy report, the world is gearing up to install 1.6 billion new air conditioners by 2050. While air conditioning is a common luxury in the United States, in most other countries it is not that common. As these countries become wealthier and grow in population, they will in... More →

Dr. Conca reports that U.S., Japan and China are racing to be the first nation to make nuclear energy completely renewable. The hurdle is making it economic to extract uranium from seawater, because the amount of uranium in seawater is truly inexhaustible.

And it seems the U.S. is in the lead. New technological breakthroughs from DOE Pacific Northwest (PNNL) and Oak Ridge (ORNL) national laboratories have made removing uranium from seawater within economic reach and the only question is, when will the source of uranium for our nuclear power plants change from mined ore to seawater e...

Revis W. James reports that California is on the verge of making a very risky bet, one that threatens CA prosperity and environment, and its contribution to global climate progress. Several groups joined with PG and E in an agreement to close Diablo Canyon in fewer than 10 years. The deal does not have much to do with global warming. Instead, it has everything to do with picking an energy mix that has a risky lack of diversity, and is going to be very complex, expensive, and unlikely to help our climate goals.

Dr. Conca reports that, aside from exposure to the Sun causing skin cancers and to radon causing lung cancer to underground uranium miners who smoke, it is very rare for anyone to be hurt by any dose of radiation. Contrary to the hype and fear pandering by the media on Fukushima, and even Chernobyl, the observable radiation health effects from both accidents were small. In the case of Fukushima, it was as close to zero as one can get. In the case of Chernobyl, although significant, it was still very small.
