What Happened When a German Car Factory Went All Electric (www.nytimes.com)

Electric vehicles have far fewer parts than gasoline cars — no radiators, exhaust pipes, fuel tanks, fan belts or complicated gearboxes. As a result, many autoworkers, executives and politicians have hypothesized that such cars would require fewer workers, leading to mass unemployment in factory towns and cities worldwide....

silence7,

I understand the desire completely, though I suspect that being grid-tied is cheaper in most locations:

  • wind is a lot cheaper with bigger turbines, which don’t make sense for individuals (though community ownership would be reasonable)
  • grid-tied systems are a lot cheaper than fully disconnected ones in most locations, and need a lot less storage, since they move electricity from where the sun shines or the wind blows to where people are
silence7,

It’s not just the upfront savings; it’s that it takes truly huge amounts of storage to deal with intermittency in one location. You need a lot less storage in the aggregate if you can move power from one location to another. This makes systems where almost everybody is connected cheaper for society as a whole.

silence7,

I’ve lived with one of those systems:

  • it didn’t use the electricity for heating, cooling, refrigeration, water heating, or cooking
  • It was 12v electricity, so you had to have specialized lighting and other appliances to use it
  • you tended to have limited electricity available in the winter

It’s not the same as the almost-always-available situation that people expect.

silence7,

Yes, if you’re not running HVAC in a northern climate. Those use enough electricity that grid-connection is incredibly valuable.

silence7,

That’s what happens when one party is bought by the fossil fuels industry. Only way to fix it is to penalize them by not giving them your vote, and working to actively support the ones who might actually do the right thing

silence7,

They’re also doing it because the amount of solar China has built is big enough to be on the verge of displacing much of the coal-fired electric generation. The article mentions this in passing as “weak demand” rather than a full description.
