Who Killed the Electric Car & more importantly, the Electric Truck?

Preface. Who cares about electric cars? Civilization ends when trucks stop running. Trucks can’t run on batteries because they’re too heavy, with 63 times less energy density than diesel. If all U.S. transportation were to be electrified, the existing electric … Continue reading

Why towns have a hard time adding EV, solar, heat pumps

Preface.  This article from IEEE does a good job of explaining how and why it is incredibly expensive for cities to cope with with L2 chargers, EV, solar, and heat pumps by zeroing in on Palo Alto, where there are … Continue reading

Building a national super grid in America

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

Net Energy Cliff & the Collapse of Civilization

figure 1. The remaining oil is poor quality, and the energy to get this often remote oil so great that more and more energy (blue) goes into oil production itself, leaving far less — the grey area — available to … Continue reading
