Lithium and many more. a recent study by the international energy agency looked at how much of those minerals are used in different electricity sources. for 1 megawatt of capacity, enough to power over 800 american homes, a natural gas inplant takes about a thousand kill agrams of minerals to construct. for a coal plant, it s about 2,500 kilograms. for a megawatt of solar power, the fuel is free, of course, but the panel takes almost 7,000 kilograms of minute nerls. onshore wind takes about 10,000 kilograms. offshore, more than 15,000. keep in mind. the sun doesn t always shine and the wind doesn t always blow, so you have to build extra solar panels and wind turbines to replace a fossil fuel plant. when it comes to transportation, the average gas-powered car contains about 35 kilograms of scarce metals, mostly copper and
What did iran agree to, remind us of that? and what is it doing today? what happened today? well, craig, iran has agreed to stop enriching uranium at 20%. it s also agreed to turn its stockpile of some 415 kill agrams of enriched uranium to 20% to use for electricity purposes or to dilute it. if they embark on that process, it s almost impossible to make it bombs grade uranium. they re diluting their whole stock pile and stopping enriching at 20% and they re not going to do work at the center of the heavy water refinery. iran has agreed to all this, but having said all that, iran hasulse said they can reverse all of this immediately. they said that if america doesn t uphold its end of the bargain, it can start enriching at 20% in just a day. iran has also been very outla
