• MIT energy conference speakers say transformation can happen fast

    The pace of advances in key clean energy technologies has been growing faster than many experts have predicted, to the point that solar and wind power, combined with systems for storing their output, can often be the least expensive options for new types of power-generating capacity. In fact, a radical transformation of the world’s energy landscape is well-underway, experts say.

  • Russia used social media extensively to influence U.S. energy markets: Congressional panel

    The U.S. House Science, Space, and Technology Committee last week released a staff report uncovering Russia’s extensive efforts to influence U.S. energy markets through divisive and inflammatory posts on social media platforms. The report details Russia’s motives in interfering with U.S. energy markets and influencing domestic energy policy and its manipulation of Americans via social media propaganda. The report includes examples of Russian-propagated social media posts.

  • Extreme weather tests U.K. gas security to the limit

    The National Grid, which manages the U.K.’s energy network, warned that it might not have enough gas to meet demand on March 1, due to plummeting temperatures and issues with supply. It has since withdrawn the warning, saying the market response has boosted supplies. But Britain’s lack of flexible energy supply is a serious issue. This isn’t the first time such a warning has been issued and it probably won’t be the last.

  • Hacker-resistant power plant software in a successful Hawaii tryout

    Johns Hopkins computer security experts recently traveled to Hawaii to see how well their hacker-resistant software would operate within a working but currently offline Honolulu power plant. The successful resilience testing, funded by the U.S. Department of Defense, was triggered in part by growing concerns about the vulnerability of electric power grids after two high-profile cyber-attacks by Russian government hackers turned out the lights in parts of Ukraine during the past two years. Neither outage in Kiev was long or extensive enough to cause serious harm or panic. Yet the attacks served as a wake-up call, putting a spotlight on power grid security in the United States and elsewhere.

  • Before the U.S. approves new uranium mining, consider its toxic legacy

    Uranium – the raw material for nuclear power and nuclear weapons – is having a moment in the spotlight. Companies such as Energy Fuels, Inc. have played well-publicized roles in lobbying the Trump administration to reduce federal protection for public lands with uranium deposits. The Defense Department’s Nuclear Posture Review calls for new weapons production to expand the U.S. nuclear arsenal, which could spur new domestic uranium mining. And the Interior Department is advocating more domestic uranium production, along with other materials identified as “critical minerals.” I have studied the legacies of past uranium mining and milling in Western states for over a decade. My book examines dilemmas faced by uranium communities caught between harmful legacies of previous mining booms and the potential promise of new economic development. These people and places are invisible to most Americans, but they helped make the United States an economic and military superpower. In my view, we owe it to them to learn from past mistakes and make more informed and sustainable decisions about possibly renewing uranium production than our nation made in the past.

  • Keeping the lights on if the world turns to 100% clean, renewable energy

    Researchers propose three separate ways to avoid blackouts if the world transitions all its energy to electricity or direct heat and provides the energy with 100 percent wind, water, and sunlight. The solutions reduce energy requirements, health damage, and climate damage. “Based on these results, I can more confidently state that there is no technical or economic barrier to transitioning the entire world to 100 percent clean, renewable energy with a stable electric grid at low cost,” says one researcher.

  • Phasing out coal: Announcing CO2-pricing triggers divestment

    Putting the Paris climate agreement into practice will trigger opposed reactions by investors on the one hand and fossil fuel owners on the other hand. It has been feared that the anticipation of strong CO2 reduction policies might – a “green paradox” – drive up these emissions: before the regulations kick in, fossil fuel owners might accelerate their resource extraction to maximize profits. Yet at the same time, investors might stop putting their money into coal power plants as they can expect their assets to become stranded. Now, for the first time, a study investigates both effects that to date have been discussed only separately. On balance, divestment beats the green paradox if substantial carbon pricing is credibly announced, a team of energy economists finds. Consequently, overall CO2 emissions would be effectively reduced.

  • Thorium reactors could dispose of large amounts of weapons-grade plutonium

    Scientists are developing a technology enabling the construction of high-temperature, gas-cool, low-power reactors with thorium fuel. The scientists propose to burn weapons-grade plutonium in these units, converting it into power and thermal energy. Thermal energy generated at thorium reactors may be used in hydrogen industrial production. The technology also makes it possible to desalinate water. 

  • Onshore wind power as affordable now as any other source; cost of solar to halve by 2020

    The cost of generating power from onshore wind has fallen by around a quarter since 2010, with solar photovoltaic (PV) electricity costs falling by 73 percent in that time, according to new cost analysis from the International Renewable Energy Agency (IRENA). The report also highlights that solar PV costs are expected to halve by 2020. The best onshore wind and solar PV projects could be delivering electricity for an equivalent of 3 cents per kilowatt hour (kWh), or less within the next two years.

  • Rejection of subsidies for coal and nuclear power is a win for fact-based policymaking

    Energy Secretary Rick Perry has repeatedly expressed concern over the past year about the reliability of our national electric power grid. On 28 September 2017, Perry ordered the Federal Energy Regulatory Commission (FERC) to revise wholesale electricity market rules, implicitly suggesting that the federal government would give subsidies to owners of coal and nuclear power plants, to compensate them for keeping a 90-day fuel supply on-site in the event of a disruption to the grid. On Monday, the independent five-member commission – four of whose members have been appointed by President Trump — unanimously rejected Perry’s proposal. FERC’s 5-0 decision shows that policymaking based on evidence won the day. Perry’s proposal, which critics said was aiming to prop up nuclear and coal power plants struggling in competitive electricity markets, had the potential to affect millions of electricity customers, as well as power markets and the environment. FERC deserves congratulations for putting evidence before action.

  • Geopolitical risks to U.S. oil supply lowest since the early 1970s

    The geopolitical risks to the U.S. oil supply are the lowest since the early 1970s, due to fracking, climate action and a more diverse global supply, according to a new study. America’s energy prosperity contrasts with a more fraught period for energy-exporting countries where geopolitical challenges have been compounded by fiscal stress and rising domestic energy demand, the authors said.

  • To reduce the number of bigger earthquakes in Oklahoma, inject less saltwater

    Starting around 2009, saltwater disposal (SWD) volume began increasing dramatically as unconventional oil and gas production increased rapidly throughout Oklahoma. As a result, the number of magnitude 3-plus earthquakes rattling the state has jumped from about one per year before 2011 to more than 900 in 2015. Oklahoma is now the most seismically active state in the lower 48 United States.


     

  • New technique could help coal plants reduce greenhouse gas emissions

    Carbon capture could help the nation’s coal plants reduce greenhouse gas emissions, yet economic challenges are part of the reason the technology isn’t widely used today. That could change if power plants could turn captured carbon into a usable product.

  • Geologists report new findings about Kansas, Oklahoma earthquakes

    In the more than three decades between 1977 and 2012, only 15 earthquakes with a magnitude of 3.0 or greater were recorded in the entire state of Kansas. Since 2012 more than 100 earthquakes of 3.0 or greater have been recorded in only two counties in the state, Sumner and Harper. These include the largest earthquake ever monitored in Kansas in November 2014, a magnitude 4.9 event near the Sumner County town of Milan. The frequency of earthquakes has continued to increase. Between May 2015 and July 2017, sensors detected more than 2,400 earthquakes in Sumner County alone, ranging in magnitude from 0.4 to 3.6. As concern rises about earthquakes induced by human activity like oil exploration, geologists report a new understanding about recent earthquakes in Kansas and Oklahoma.

  • Reusable sponge soaks up oil, revolutionizing oil spill and diesel cleanup

    When the Deepwater Horizon drilling pipe blew out seven years ago, beginning the worst oil spill in U.S. history, those in charge of the recovery discovered a new wrinkle: the millions of gallons of oil bubbling from the sea floor weren’t all collecting on the surface where it could be skimmed or burned. Some of it was forming a plume and drifting through the ocean under the surface. Scientists have invented a new foam, called Oleo Sponge, that addresses this problem.
