Planet of the Humans, a full documentary by Jeff Gibbs presented by Michael Moore, arguing that the green movement has been co-opted by corporate and wealthy interests and that techno-fixes are not enough.

A Technology Connections video on how ground-source (geothermal) heat pumps work and why they hold efficiency in winter. It also covers related heat pump information, and the description notes air-source heat pumps have since improved.

Joran Dirk Greef's Systems Distributed '23 talk on TigerStyle, the engineering methodology behind TigerBeetle. It covers designing safer systems in less time through up-front design, assertions, and deterministic simulation.

A long Technology Connections video arguing that public understanding of renewable energy is distorted. It covers solar economics, land use compared with ethanol corn, and battery myths such as cobalt.

A feature-length film by the Makani team chronicling their thirteen-year effort to build energy kites that harvest wind power, with footage from test sites in Hawaii, California and Norway. It shows the engineering, the team and the eventual shutdown.

Technology Connections' long closing video in his heat pump series, arguing that adopting heat pumps is well within reach. It explains how they work and what it takes to start using them.

Practical Engineering explains why connecting solar and other inverter-based generation to the grid is hard. It covers grid stability, load balancing and the behind-the-scenes engineering challenges of renewables.
