** Caution: EXTERNAL Sender ** I red the artcile concerned. The author wrote that Einstein’s equation E = mc^2 only works if you use metric units. This is not entirely true. Einstein’s equation works for ANY coherent system of units – it is just that the Imperial system is not a coherent system of units. For those who are interested, the Planck system of units is a coherent system (See https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FPlanck_units&data=05%7C01%7Cusma%40lists.colostate.edu%7C1028853fb47b4a46266308db1f5bd9a7%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C638138251725574858%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=RwJ9y%2BDvy1HbZFkS83QF5pFGFkHhaNZMFsGQaQuyRc0%3D&reserved=0), though none of the units in that system are named.

Now there are people who think they can fight climate change by cooking with electricity. About 80% of electricity in the U.S. comes from fossil fuel or nuclear power plants, according to the U.S. Energy Information Administration https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.eurekalert.org%2Fnews-releases%2F980038&data=05%7C01%7Cusma%40lists.colostate.edu%7C1028853fb47b4a46266308db1f5bd9a7%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C638138251725574858%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=jaB%2BHgLz7tOtyNQ%2FG68s2wK9sqyNVshmdeR%2Begl%2FRd4%3D&reserved=0<https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.eurekalert.org%2Fnews-releases%2F980038&data=05%7C01%7Cusma%40lists.colostate.edu%7C1028853fb47b4a46266308db1f5bd9a7%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C638138251725574858%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=jaB%2BHgLz7tOtyNQ%2FG68s2wK9sqyNVshmdeR%2Begl%2FRd4%3D&reserved=0> if you have 1 MJ of 0 emissions electricity, if you use it to replace electricity produced by fossil fuel, you save close to 3 MJ worth of burning fossil fuel. if you use it to cook by electricity, you save 1 MJ worth of burning fossil fuel. to minimize co2 emissions you should replace electricity produced by fossil fuel and continue to cook with gas. Also, Peter i like the fact that you use the international date standard which follows the rules of math.
