The Promise of Geothermal Energy
Geothermal energy has a lot going for it. It’s a domestic power source that is clean, reliable and proven. It also is plentiful. But there are challenges holding geothermal energy back. Researchers are working on ways to overcome some of those barriers.

International Effort to Improve Urban Resilience
Extreme climate events are severely affecting communities in the U.S. and around the world. The examples are plenty. Bushfires in Australia, wildfires in California, flooding on both U.S. coasts and inland, and much more. In the face of extreme climate events, experts explore developing nature-based solutions.

Sustainable Supply of Rare Earth Minerals Key to Low-Carbon Energy Future
The global low-carbon revolution could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply of rare minerals and metals, a new study has warned.

A New Way to Remove Contaminants from Nuclear Wastewater
Nuclear power continues to expand globally, propelled, in part, by the fact that it produces few greenhouse gas emissions while providing steady power output. But along with that expansion comes an increased need for dealing with the large volumes of water used for cooling these plants, which becomes contaminated with radioactive isotopes that require special long-term disposal. New method concentrates radionuclides in a small portion of a nuclear plant’s wastewater, allowing the rest to be recycled.

5. The Ransomware Menace
Experts say that 2019 should be declared the Year of Ransomware Escalation. The increasing number of attacks and the move by perpetrators to target large companies and public institutions in the United States and abroad is a turning point in the evolution of this digital form of blackmail.

U.S. Military Precariously Unprepared for Climate Threats, War College & Retired Brass Warn
A series of climate-related disasters has paralyzed the strategic capabilities of several U.S military bases in recent years. David Hasemyer writes that it has exposed the military’s vulnerability to extreme weather, shining light on its failure to prepare adequately and on the consequences this lack of preparation could have for U.S. national security.

On-Demand Drinking Water from Air
Providing potable drinking water to deployed troops operating in low resource or contested environments is no simple undertaking. Logistics teams face great risk delivering water and often incur what would otherwise be preventable casualties. Low-power extraction technologies could capture potable water from ambient arid air, giving deployed troops greater mission flexibility.

GOP Senators: Chinese Drones Pose National Security Threat
A group of GOP senators called on the administration to restrict the use of Chinese drones by U.S. government agencies. “American taxpayer dollars should not fund state-controlled or state-owned firms that seek to undermine American national security and economic competitiveness,” they write.

Predicting Power Failures Which Could Lead to Wildfires
Imagine a tool that can discover problems on utility lines before outages, before power failures spark deadly wildfires, or before fears of wildfires prompt massive, pre-emptive power outages such as those suffered recently by millions of Californians. Well, the tool exists. It is available today. And it works.

The Earth Needs Multiple Methods for Removing CO2 from the Air to Avert Worst of Climate Change
Concentrations of carbon dioxide in the atmosphere are higher than at any time in human history, and nine of the warmest years have occurred since 2005. “Avoiding catastrophic impacts on our coastal infrastructure, biodiversity, food, energy and water resources will require more. In particular, many climate researchers like myself believe government needs to advance technology that will actually suck carbon dioxide out of the air and put it away for very long periods,” David Goldberg writes.

Lessons Learnt from Fukushima Soil Decontamination
Following the accident at the Fukushima nuclear power plant in March 2011, the Japanese authorities decided to carry out major decontamination works in the affected area, which covers more than 9,000 km2. The European Geosciences Union (EGU) has published a collection of studies providing an overview of the decontamination strategies used and their effectiveness.

The Nexus Between Nuclear Energy & Nuclear Security
Despite the plentiful and relatively cheap energy available in the upper-income countries, nearly one billion people worldwide have no consistent access to electricity, with another one billion having reduced access to healthcare due to energy poverty and a further 2.7 billion relying on biomass as their primary source of energy. Any program hoping to ameliorate these challenges would almost certainly require a radical expansion in global electricity generation. While renewable energy sources, including solar, wind, and hydroelectric power, will inevitably play a role in any low-carbon future, any genuinely sustainable energy future would also require a massive investment in nuclear energy.

Harnessing Nature’s Defenses against Tsunamis
As sea levels rise and adverse weather events become more common, vulnerable coastal communities are at increasing risk of devastation from storm surges and tsunamis. The death toll from tsunamis, at 260,000 during the past century, was higher than that from any other natural hazard. Researchers say that biodiversity can help in protecting coastal communities.

Helping Strengthen America’s Critical Infrastructure
Everyday life depends on a robust infrastructure network that provides access to running water, communications technology and electricity, among other basic necessities. The experts who keep our national infrastructure secure and resilient also need a strong network to share their knowledge and train the next generation of professionals capable of solving complex infrastructure challenges.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
Using Liquid Air for Grid-Scale Energy Storage
New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.
Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
