An emerging perspective in U.S. public discourse claims that a buildout of renewable electricity would exacerbate supply risks, mining intensity, and import dependence. This ScienceDirect article from fellow Jim Krane and graduate student Robert Idel contends the opposite is true, demonstrating how transitioning to renewables hugely reduces the materials, mining and political risk involved compared to coal.
It now seems technically feasible to culture human embryos beyond the “fourteen‐day limit,” which has the potential to increase scientific understanding of human development and perhaps improve infertility treatments.

Medlock, senior director of the Center for Energy Studies.
