Interest in Geothermal Energy is Growing
These days, some 400 power plants in 30 countries generate electricity using steam generated beneath the earth’s surface, producing a total capacity of 16 gigawatts (GW). Despite its advantages, geothermal energy has seen limited use compared to fossil fuels, but recent energy shocks have increased interest in this energy source.

Towers in the Storm
The problem with the U.S. electrical grid is that many transmission towers have exceeded their design life by about 50 years, which means the aging grid today faces bigger chances of failure. One threat to the grid is from damaging winds of extreme storms such as hurricanes.

Concerns About Extremists Targeting U.S. Power Stations
Attacks on four power stations in Washington State over the weekend added to concerns of a possible nationwide campaign by far-right extremists to stir fears and spark civil conflict. Violent extremists “have developed credible, specific plans to attack electricity infrastructure since at least 2020, identifying the electric grid as a particularly attractive target given its interdependency with other infrastructure sectors,” the DHS said in a January.

Addressing the Needs of Underprepared Communities
Many regions in the U.S. do not have regular earthquakes. Still, they have faults that can create large earthquakes, and communities in these regions are not prepared to experience a large quake with the capacity to cause significant damage. A new center will specifically address areas of low probability of occurrence but high impact earthquake risk and seek to meet the needs of all communities for natural hazard mitigation.
