If we really cared about CO2, we’d reduce car size and weight, not make electric cars

Preface. Since my book “When trucks stop running: Energy and the future of transportation makes the case that it’s trucks that need to be electrified to keep civilization going, since biofuels don’t scale up, natural gas and liquefied coal are … Continue reading

Wind and solar need natural gas to balance intermittent, variable, and seasonal power

[ The highest wind states are getting to be enormously dependent on natural gas to balance wind and solar as this EIA article about California below shows.  Yet conventional natural gas has peaked — half our natural gas– and is … Continue reading
