No Significant Relief from Global Warming

And how ****ed they re with the new tariff, which brings their prices up to something more competitive to the less (but still) subsidized US manufacturers. It will raise the price of panels, of course. But panels are already one of the less expensive parts of any PV system. Heh. And solar is still subsidized in the US by a couple orders of magnitdue more per MwH than fossil fuel generation. No. The traditional fossil fuels are petroleum and coal, both of which are now being priced out of the energy generation market. More by the low prices of natural gas than the high prices of either, of course. There's a real glut of natural gas these days, and it's not likely to end soon. Coal will not recover. And really won't be missed much. Though I suspect it will continue to provide material for manufacturing for centuries. It's simply too dirty and too expensive to clean. It was already being priced out even before cheap natural gas showed up. Petroleum costs will depend upon supply, but most evidence points to that diminishing. Meanwhile, solar and wind will certainly continue to get cheaper. Except when it gets more expensive, as the subsidies end. Yeah, hold your breath on that. It will take a lifetime to build enough infrastructure and generating capacity to replace gasoline powered cars with eelectrics (which will required at least a 1/3 increase in total capacity in the US). That's almost certainly a myth. Most of the infrastructure already exists right in people's homes. No, it's not. The US currently uses the equivalent of about one terrawatt-hour in gasoline every year. That's about 1/3 of the total electrical generating capacity in the US right now. There isn't that much excess generating capacity, nor is there enough transmission capacity in the current grids to handle that much more. And if you want to use your current 110v outlet to charge your electric car, you'll be waiting at least 8-10 hours for every three or four you drive. And you'll almost certainly be doing so during peak usage hours. (Where people live - like southern California - electricity is *more* expensive than gasoline per mile drive, by at least twice as much.) Then, of course, there's the very large number of people who rent their homes. My apartment complex isn't going to install $50,000+ chargers for each of the almost 200 units without raising the rest well beyond anything I could afford. And there's no enclose cparking, so even if they did, people would steal the copper anyway. I, at least, have off stree parking. Many do not. Do you expect cities to install $50,000 chargers like parking meters? But the real killer, the thing for which there simply isn't a vaiable solution, is energy transfer times. You can put enough gas into a car to travel 300+ miles in about three minutes. For a home charger, that's 8+ hours. For the commercial chargers in use today, 50 kw unites, that's still 2-3 hours. For Proche's proposed 350 kw chargers, it still 20 minutes. Using existing technology, a gas station with 16 pumps today would need nearly 200 charging stations (at $50k+ each) to service the same number of vehicles. And a 30 megawatt power circuit coming in. To transfer energy as quickly - 300+ miles of driving in three minutes - would require a 3 megawatt charger. Do you *really* want to see the average moron who is trying to shave and eat breakfest while driving handling ap irce of wire that that will literally explode if mishandled? (With debris likely causing a chain reaction with other chargers)? 30 megawatt circuit per gas station. There are 680,000 places in the US that sell gasoline. (Aside from the fact that there simply isn't enough lithium production in the world to build a couple hundred million cars, nor will there be any time soon. And that's just the US.) No, it's not a myth. Electric cars will soon be fine for a second vehicle as a daily driver for people who don't commute too far. But they cannot do everything a gasoline car does. So most people have the choice of either buying a gasoline car that does everything they need, or an electric car that doesn't, or buying two cars. Good luck with that. Battery technology is not dependent upon foreign materials, Are there rare earth mines actually productive in the US now? China is the biggest producer, and they've already manipulated the market to protect their own interests. Battery technology does not utilize much in the way of rare earths. It does utilize ltihium, which has its own issues. there is no military cost. Today. Why would there be if we're not dependent upon foreign sources for materials? China is the biggest producer of rare earths. Which are used in battery production, and wich are absolutely required for the electronics needed for charging. (And without the electronic controls, lithium batteries are far too dangerous for consumer use.) And battery technology does not have a large environmental impact. Now you're into retard territory. That's not an intelligent response. You didn't offer an intellectual statement. You said something *stupid*. There is lots of information out there about the environmental issues surrounding batteries. The lead acid battery industry achieves near 100% recycling, and is viewed as a model for how other battery lifecycles can be modeled. The toxins in the batteries and used for manufacturing are usually not significant, and are manageable. Not when you scale it up to the 60 million cars manufactured every year. (And there isn't enough lithium production to support that anyway.) We don't see environmental releases from batteries (and certainly not at the levels we see from burning fossil fuels). We don't see 1% as many electric cars being manufactures as gasolien cars, either. Nor do the production of wind or solar production equipment. Wind, less so. Solar requires exotic materials, as do high tech batteries, both of which have environmental implications for manufacture, and disposal after they're worn out. No, not really. The bulk of the materials are not in the least exotic So you agree that some of the materials *are*. 60 million cars a year. and the manufacturing processes are the same or similar to what we see in a great many products today, where environmental impact is well controlled.
