Solar energy conversion breakthrough
Scientists say that sunlight falling on only 9 percent of California’s Mojave Desert could power all of the U.S. electricity needs — if the energy could be efficiently harvested; this is a big “if,” since current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications; Northwestern University researchers show a way to increase solar cell efficiency

The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Water Is the Other U.S.-Mexico Border Crisis, and the Supply Crunch Is Getting Worse
The United States and Mexico are aware of the political and economic importance of the border region. But if water scarcity worsens, it could supplant other border priorities. The two countries should recognize that conditions are deteriorating and update the existing cross-border governance regime so that it reflects today’s new water realities.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
