Peak lithium makes transportation & electricity storage pointless
Preface. The lithium batteries in cars need electricity to recharge, but the electric grid can’t stay up with just wind and solar, that’s why natural gas is the energy storage today. Nor do pumped hydro or compressed air energy storage … Continue reading
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
