High-level nuclear waste storage degrades faster than thought

Posted on June 15, 2020 by

Preface. Burying nuclear waste ought to be a top priority, now that it appears peak oil may have happened in November of 2018 (Patterson 2019) and perhaps even sooner if covid-19 crashes the world economy (Tverberg 2020). It won’t happen … Continue reading →

Building a national super grid in America

Posted on June 3, 2020 by

Preface. Renewables are not evenly distributed.  Just 10 states have 80% of hydropower (Homeland Security 2011), 10 states produce 75% of wind power (EIA 2017), and 10 states produce 79% of solar power (CE 2020). With a national grid, instead … Continue reading →
