gowlerk 2,275 #26 January 27, 2018 QuoteBy moving all the manufacturing overseas we've also moved coal mining there. I've gotta disagree with this part only. Coal jobs are down for two reasons. Depressed prices due to competition from natural gas and increased mechanization. Coal can only be mined from where it is. While there is a lot of it in the world, America is "blessed" with huge reserves of cheap to mine coal.Always remember the brave children who died defending your right to bear arms.

You comment implies that you can just replace coal with solar. You cannot.

I think this >is a good thing. That is a good thing. The bad thing is the hit that the solar installation industry will take, which overall employs a lot more people than the solar manufacturing business. (You can automate one; you can't automate the other.) So far the best estimate to the number of local installation jobs to be lost is 23,000. Will Tesla (and other panel manufacturers) hire 23,000 people to make panels, when a typical panel fab line requires about a dozen people to operate it? Probably not - which means a net loss of tens of thousands of jobs. Now, maybe it's so important to punish the Chinese that 23,000 jobs is a price we are willing to pay. Odd, though, that the two companies that pushed for this tariff are Chinese and German. Quote Share this post Link to post Share on other sites

billeisele 130 #31 January 28, 2018 energy policy is a complicated topic, here on the East Coast there are State social welfare programs (tax incentives) that go along with the federal social welfare combine those subsidies together and solar can compete economically with conventional generation, remove the subsidy and the industry dies under the weight of economics Trump is not killing it, the social welfare that is not sustainable once removed kills it, unless the cost of the technology drops another 20-50% i'm not anti-solar but don't like paying a tax so a solar user can have panels the other issue is the solar user isn't paying their share of the grid costs, if they want to be independent that's fine, disconnect from the grid, but solar without storage only provides power 23% of the time under the best circumstances, so these folks want to stay connected to the grid but don't want to pay their fair share of the costs of the grid, that's not fair some utilities have rate structures that remove the subsidy, in those cases the solar owner pays their fair share of the grid costs, but then the economics of solar are terrible so almost no one does it and that's how it should be these facts are different in different parts of the countryGive one city to the thugs so they can all live together.

Oh, there are still leather products sewn in US. But the leather is tanned overseas. Raw hides are brined at the packing plants, loaded into containers, and sent to India.

But most or the hides go overseas. http://8020usa.org/2017/02/5-tanneries-sticking-made-usa/ This is a website listing some of the "tanneries still in the USA" From an industry report: QuoteUS hides and skins companies – including producers, processors, brokers, and dealers – regularly export more than 90 percent of total US production and are one of the top raw material suppliers to the global leather manufacturing industry. http://www.rendermagazine.com/articles/2017-issues/april-2017/us-hide-skin-and-leather/ How do I know about this? I once worked for a trucking company that hauled stinking wet cowhides from Alberta to a port near Houston. One of the worst jobs I ever had.

wmw999 2,588 #43 January 28, 2018 One of the ways to make things like solar work is simply to reduce overall need by choosing technologies. LED lights, charging rechargeable computers etc during the day, using fans and passive cooling instead of cranking up the A/C in ever-bigger houses. USA favors the more-is-better approach to its detriment. Just look at serving size and food waste in restaurants. We'll waste a lot for a minor increase in perceived convenience. Not just USA, but we seem to be trying to perfect it. And ads keep telling us that we can have it all, and that we deserve that whatever.

Bob_Church 7 #44 January 28, 2018 The same summer that the School of Art was having all of its electrical system replaced to keep up with demand by Wife's parents moved into a retirement community in Wisconsin. I got to talking with the maintenance man about the problem and he laughed. He said that when they designed the electrical supply for the place they took absolutely everything into consideration and basically doubled that. They could put a window a/c unit in every room and each have their own personal computers, and the list went on. There's no way this could fail. Then a couple of years after that those electric carts came out. And everyone, no exaggeration, everyone got one, including Vivian. The area around the dining room looked like a storage area for a golf course. And right after dinner, every night, they all ride them back to their rooms and plug them in. And you could hear the breakers popping. They've added and rearranged to take care of that situation but now nobody says "well, we definitely won't have any problems now."

And no one has yet come up with an acceptable answer to waste > disposal. It is essentially a dead technology. In terms of modern nuclear, I tend to agree. People had high hopes for the GE AP600/1100 series of cheap, safe reactors. But by the time any were actually built (as AP1000's) they ended up being even more expensive than conventional reactors. Westinghouse shed the division making them; Toshiba bought the division and tried to make a go of it. Then that division of Toshiba went bankrupt. It was just purchased by investment bankers which is a little worrisome. They are high up on the list of "people you don't want in charge of a nuclear power project." Meanwhile the only two projects in the US using AP1000's - the Summer Plant expansion and the Vogtle expansion project - have been cancelled after massive cost overruns and delays. (Vogtle is $9 billion over budget and 5 years late.) A recent regulatory decision may save Vogtle for the time being, but since the decision does not say who will pay the extra $9 billion or so, it's pretty tenuous. If it's ratepayers there will likely be a revolt, and if it's the utility they will either have to declare bankruptcy or cancel it themselves. There's a lot of hope on the horizon for new technologies - but then again, there's new hope about once every ten years, and they never seem to pan out. PBMR's (pebble bed modular reactors) were the big thing for a while (hydrogen economy! inherently safe!) but they didn't pan out. Today small modular reactors and thorium reactors are the big new thing. And I hope they pan out and give us a cheap, safe source of power - but it's hard to see why this latest crop will be different from all the promises going back over 60 years that we will soon have nuclear energy "too cheap to meter."

The moment it snows, or leaves cover your panels, or your neighbor's tree or clouds block the sun your panels are not generating power.

You don't get all your power from the coal plant just down the road... You know that, right? It goes into a grid where it is produced, stored and distributed by all the production facilities on that grid. You get just as much of your power from a power station 500 miles away as one 5 miles away. The same would be true of solar. The people in the snowy climates would get their power generated by solar farms in the desert if it became an industrial / societal power generation.

billvon 3,116 #49 January 29, 2018 >But being realistic, solar isn't going to work as a main source of power for anyone that > lives where it snows. There are thousands of off-gridders who use solar as their main source of power all year in places from Hawaii to Minnesota. One trick is to orient the panels vertically during winter; no snow then sticks to them (and they generate the most energy in the winter at that angle.) And, when it snows, you get the reflectance gain - and solar panels are more efficient when it's cold. In San Diego (a great place for solar) people generate, on average, about 5 kwhr per meter of panel per day in January. In northern Maine, people generate, on average, about 3.9 kwhr per meter of panel per day in January. That's a significant, but not insurmountable, difference. It's not even 2x. Twenty years ago, when panel prices were $10/watt, that meant solar couldn't work in Maine. A month ago, when panel prices were $.75/watt, that meant solar can (and did) work in Maine. The rapidly dropping price of solar means that even the 22% lower harvest you get in Maine during the winter isn't a dealbreaker. (Provided, of course, we don't do mind-numbingly stupid things like putting a special tax on them to protect Chinese and German companies.) >Solar will never realistically be the main source of energy - within this century at least I disagree. Solar-PV is growing 20% a year, and right now supplies 1.5% of electrical energy in the US. That means if all we do is keep that growth rate going we're over 10% by 2028, and over 50% by 2037. >and if we are going to meaningfully reduce CO2 emissions to stop global warming, we >need to do it now. Not start 100 years from now. We are doing it now. 2037 is a pretty good goal for over 50% renewables for the electric grid. Of course, solar won't be the only renewable out there. Wind will be a big part of the equation. I am hopeful nuclear will too, and that the new designs out there pan out. But like you said, we have to start now - we can't wait 40 years until someone finally comes up with a cheap, reliable, safe nuclear power technology.
