If Tesla Can Run Its Gigafactory On 100% Renewables, Why Can't Others?
Lucas123 writes Tesla CEO Elon Musk has said his company's Gigafactory battery plant, the world's largest, will be "self contained" and run on solar, wind and geothermal energy. The obvious problem with renewable sources is that they're intermittent at any given location, but on a larger scale they're quite predictable and reliable, according to Tom Lombardo, a professor of engineering and technology. Lombardo points out that Tesla isn't necessarily going off-grid, but using a strategy of "net metering" where the factory will produce more renewable energy than it needs, and receive credits in return from its utility when renewables aren't available. So why can't other manufacturing facilities do the same? Is what Tesla is doing not necessarily transferable to other industries? Sam Jaffe, principal research analyst with Navigant Research, believes Tesla's choice of locations — Reno — and its product is optimal for using renewable and not something that can be reproduced by every industry.
Germany is well on the way to doing this on the scale of a whole country. It just takes some political will.

Tesla is selling $100k cars, while other battery factories make batteries for $100 phones and $500 laptops. Maybe it is too expensive for them to set up a fully renewable process.
Wealth is the gift that keeps on giving.
It's because people like you want a $600 smartphone device every 2 years made by a Chinese worker getting $1 an hour using 100s of toxic, cancerous materials, all processed by coal power.
In the race to the top in the present it's the future generations that come in last.
The fiction of net metering is that you will not be paid the same amount for the electricity you generate as for the electricity you consume.
On of the purposes of "Smart Meters" is to permit differential pricing on electricity produced vs. consumed; it's not just to provide a temporal demand market. There are already tariffs in place in California where PG&E only has to buy as much electricity as you consume for a net 0 energy usage, rather than being required to purchase everything you generate over what you consume.
The idea of a large grid only works if someone pays to maintain that grid, and that pricing comes in as a differential.
Everyone can't do what Tesla is doing because not everyone is going to have the storage capacity to make it economical; Tesla can just rota the batteries it manufactures in service to the manufacturing plant itself, as part of "burn in testing", so that it'll get local off-grid storage as a side effect of the manufacturing process itself.
I suppose that "every rechargeable battery manufacturer can do what Tesla does" would be a fair statement, but that's a tiny subset of "everyone"
You cannot base any real analysis on figures take by looking at an artists rendering of the site.
The article says that they will have 85 windmills because there are 85 windmills in the picture. This is garbage. It is an artists rendering!
If you want to have a serious discussion, you have to wait until there is some actual real info to discuss.
Note that net metering is not running your plant completely off renewables. It's running it off renewables some of the time.

Lackadaisical safety management is dangerous.
I teach physics. The most depressing part of my job is teaching a general-education class where I have to explain global warming.
Scientists don't have a private agenda. We would LOVE to be wrong about this, but:
- Temperatures are going up worldwide
- Global temperatures are historically very well correlated to CO2 concentrations
- CO2 concentrations have a straightforward and well-understood effect on infrared light produced by
earth's blackbody radiation
- Even small changes to global temperature will create big changes to local climates
- We can stop this, but only if radical action is taken right now
so
- We're all fucked.
This is not the time for the debate about whether the effect is real. This is the time for debate about just how MUCH we should be panicking. We're in the deep shit here. We're talking about large proportions of humanity not having enough food to eat. The resulting warfare and hardship will be devastating.
