Suddenly, Yucca Mountain is being discussed again. Officials in South Carolina are in favor of it and 28 other states with nuclear reactors are also in favor of finishing the Yucca Mt. Nuclear Storage Site.

The notion of protecting Yucca Mountain enjoyed powerful Washington allies for years, notably Sen. Harry Reid of Nevada, the Senate Democratic leader from 2005 until January, and President Barack Obama. But Obama is no longer the president, Reid is no longer a senator and Democrats do not control Congress or the White House.

Anya Litvak opines that either the Ohio-based company will shut down the 1,800-megawatt plant, two decades ahead of schedule, or it will sell it to another operator. The latter option is a nonstarter unless something, aka someone, aka legislators in Pennsylvania and Ohio, intervenes to equalize nuclear energy with gas.

The Beaver County nuclear plant and two others in Ohio share the same chopping block as about a dozen fossil fuel plants in FirstEnergy portfolio across several states where electricity generation is not directly supported by ratepayers.

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

Charles Kenny blogs that while (some in) the U.S. remain lukewarm about nuclear power, shutting down plants (because of low natural gas prices), the developing world is rapidly adding capacity. Ten new plants came online in 2016, nine of them in the developing world, supporting the largest addition of nuclear power since 1990. This is good news for people living in developing countries and for the global climate, but to make faster progress with safer designs (but can not get much safer), it is high time America started investing in next-generation nuclear power (but that is already well under...

September 30, 2016, scientists and engineers at the MIT Plasma Science and Fusion Center made a leap forward in the pursuit of clean energy. The team set a new world record for plasma pressure in the Institute Alcator C-Mod tokamak nuclear fusion reactor. Plasma pressure is the key ingredient to producing energy from nuclear fusion, and MIT new result achieves over 2 atmospheres of pressure for the first time.

Nuclear fusion has the potential to produce nearly unlimited supplies of clean, safe, carbon-free energy. Fusion is the same process that powers the sun, and it can be realize... More →

Index / Solar Energy / Space and Other Applications

Cade and Chan-Park (2015) report that although space weather is a fairly recent term, there is a rich history of similar terms being used beginning in the middle to late 1800s. Solar meteorology, magnetic weather, and cosmic meteorology all appeared during that time frame.

The actual first appearance of space weather can be attributed to the publication Science News Letter in 1957 (with the first modern usage in 1959) and was possibly coined by the editor at the time, Watson Davis.

More broadly, from the earliest days how did humanity refer to the science that we now cal... More →

Changes in the dynamics and composition of solar wind (a component of space weather) interacting with Earth magnetic field can lead to geomagnetic disturbances (GMDs). GMDs occur regularly and can induce electric currents in long conductors that form the backbone of infrastructure systems such as the electrical power grid, gas and oil pipelines, and railways. Geomagnetically induced currents (GICs) can disrupt and potentially damage these systems, which are critical to the economic and social well-being of many nations.

Rebecca Boyle blogs that since the 1960s, Mars exploration has either been conducted by robot surveyors or confined to opaque dreams of human visitors. The first path has been an unqualified success. Humans have sent twenty-odd spacecraft to Mars, and uncrewed ships have uncovered many of the red planet secrets.

NASA robotic missions have been following water, which suggests a habitable history, and have found plenty of evidence that Mars was once balmy and damp. Robotic orbiters and planned landers from Europe, Russia, China and India (none landed successfully, save for one Russia... More →

Koerth-Baker blogs that the treaties that govern space allow private individuals and corporations to travel the stars, but only with the licensure and legal backing of an earthbound government. It is similar that way to the laws of the sea. And today, on Earth oceans, more than 11% of all the tons of freight shipped is carried on boats that fly the Liberian flag. In exchange for lower taxes and looser regulations, both the shipping companies of the present and the Martian explorers of tomorrow could pay to register their vessel with a small country they have no other connection to and carry it...

Dom Galeon reports that signs that fossil fuels are on the decline are everywhere. For one, nations are keen on cutting down their fossil fuel consumption. Then there is the growing solar energy business that is looking to overtake coal? The technology industry is also taking steps to ensure the demise of fossil fuels. And, in perhaps one of the clearest signs of decline, the Navajo Generating Station near Page, Arizona, announced that it will be closing by 2019, more than two decades ahead of its EPA-mandated 2044 shutdown.

David Jacobson reports that in a manuscript accepted for publication yesterday, new evidence for 10 ground-rupturing earthquakes prior to 1857, along the Big Bend of the Southern San Andreas Fault was presented. The study, headed by Dr. Katherine Scharer at the USGS in Pasadena, examined the earthquake history of the San Andreas near Frazier Mountain in northeast Kern County. This area last ruptured in the 1857 M=7.7-7.9 Fort Tejon earthquake.

One of the reasons why this location is of importance is because in Southern California, the Big Bend, Carrizo, and Mojave sections of the Sa... More →

Dr. Conca opines that oil is more plentiful than we all imagined. And we keep figuring out easier and more economical ways to get it out of the ground, but what are we going to do with it in the future?

In 1938, the famous geologist M. King Hubbert came up with the concept of peak oil, which is defined as having extracted half of the recoverable, conventional oil reserves. After that, oil production declines and cannot keep up with growing demand as the population continues to rise.

In Hubbert time, most of the conventional oil reserves had already been discovered. Hubber... More →

The U.S. G.S. reports that conducted properly, hydraulic fracturing has little possibility of contaminating groundwater supplies. Properly constructed wells are intended to prevent drilling fluids, hydraulic fracturing fluids, deep saline formation waters, or oil and gas from entering aquifers located thousands of feet above.

Carefully constructed and operated well sites have the ability to contain potential spills and minimize runoff into surface waters. However, oil and gas drilling in general is an industrial activity in which it is possible for accidents to occur that result in ... More →

Dr. Conca opines that investing in a backup planet might be a good idea, given what has been happening on Earth lately. The cost would only be a little over $20 trillion, but some nice real estate just came on the market. The discovery of seven Earth-like planets orbiting a nearby star has really gotten everyone thinking about space colonization again. Found by NASA orbiting Spitzer Space Telescope and the ground-based TRAPPIST Telescope, there seems to be at least seven Earth-sized planets orbiting the star TRAPPIST-1.

Colin Smith reports that bubbles acting like parachutes are deployed by some cosmic dust particles on their entry into Earth atmosphere, preventing them from burning up. This is the conclusion of a new study carried out by geoscientist, Matt Genge, from Imperial College London.

Cosmic dust particles originate from events such the arrival of comets in the inner solar system and collisions between asteroids, which pulverizes them into dust. Some make it through the rapid descent through Earth atmosphere, providing microscopic records of some of the earliest events in our solar system... More →

Edmonds, M., and C. Manning (2017) report that carbon is one of the most important elements on Earth. Its distribution on and in Earth affects the global climate system, the origin and evolution of life, and the types and availability of energy resources. The geological cycling of carbon, driven by plate tectonics over long timescales, is the main factor influencing the size of the Earth shallow carbon reservoirs. Until recently, however, a fragmented understanding of how much carbon resides in the deep Earth, its form, and how it moves between deep and shallow reservoirs.
