San Francisco was mentioned in the article, they purchase their energy from Pacific Gas & Electric, which generates the vast bulk of its electricity using generators that burn natural gas. Where do these ascientific chucklefucks think electricity comes from? I guarantee that all electricity generation comes with an environmental integrity price tag: Wind kills birds, is incredibly expensive and resource-intensive, and we saw that it fails when you need it the most when Texas had their recent cold snap. Hydroelectric generation kills rivers and drowns entire landscapes, fission generates both high-level and low-level nuclear waste that is highly toxic and lasts ten to twenty times longer than all human history so far, fusion generates fast neutrons that will eventually turn the reactor itself into a cooked toxic nightmare of ionizing radiation, and fossil fuels and natural gas are limited natural resources that might be more valuable as a source of chemicals than as a simple chemical energy source in the long run (I do not count generation of CO2 as an actual problem to be worried over or solved though). We're better off using the chemical energy sources we already have, while we search for real alternatives such as Fuel Cell tech and maybe even something elegant and subtle like Zero Point Energy. And work on making our tech more efficient whenever possible. And stop wasting energy on idiocy like breeding nigger meat through targeted programs designed to do so.
