Ideally you would pair these 4-hour batteries with CHEAP sources of electricity. Fill the battery when electricity is cheap, empty the battery when electricity is expensive (ie, when demand spikes or when other sources of generation drop off the grid).

The cheapest source of electricity today is noontime solar. Batteries can fill up on noontime solar and discharge into the evening peak. They could also charge on wind or traditional baseload sources overnight, and discharge into the morning peak.

I think that's because we've made it politically difficult to build transmission. In the United States, you have to get approval from every jurisdiction and landowner along the route, so valuable transmission lines are politically impossible to build. (See: SOO Green, Grain Belt Express, BECI, other planned lines).

Oil and gas pipelines are centrally approved by FERC, so there is no such difficulty. It doesn't have to be so difficult to build transmission, and it would unlock a lot of wind and solar development.

It says in the linked article that they only have support for 9 cities so far, and they list them as:

Spokane, WA

Syracuse, NY

South Bend, IN

Bellingham, WA

Morgantown, WV

Cincinnati, OH

St Paul, MN

Rochester, NY

New York City, NY

It also says that they are working on improving the data pipeline so that they can reduce the amount of time it takes to add new cities to their dataset and visualization.

Nooo... we have a bunch of metrics and logs reporting systems at my company. Some of them are in UTC, some of them display my local time, some of them display China Time, and I'm trying to collaborate with colleagues in London and Australia who get data displayed in their local times as well. When I'm working to address an incident and combing through multiple systems to try to correlate events, it's a pain in the ass having to constantly double-check which time zone this data is in.

If China is manufacturing solar panels for us, that doesn't give them control of our energy supply.

It's not like being dependent on Saudi Arabia to supply oil. If China cuts us off from new solar panels, the solar panels we already have continue to provide electricity. It would only slow the rate of deployment, which we're already doing to ourselves by imposing a tariff on solar panel imports.

Some of the housing regulations were legitimately put in place for safety reasons to protect people. Others were put in place to keep black and Asian people out. Especially after government initiatives to prevent discrimination in housing like the 1968 Fair Housing Act, efforts to keep out minorities became cloaked in the garb of "public safety", and minority-excluding regulations were sanitized into affordability-excluding regulations.

The energy efficiency initiatives of the 1970s significantly reduced the energy cost of economic activity. (Ironically, this helped kill nuclear, by undercutting the expected increase in demand that utilities built all those nuclear power plants to meet.)

The ongoing clean energy transition could bring us cheaper energy and divorce grid energy usage from greenhouse gas emissions.

I feel like the future is looking bright.

The goal is to eliminate trash in the environment. Thin plastic bags get discarded carelessly, then catch in the wind and get strewn around a wide area.

Plastic bag bans have been sufficiently successful that people have forgotten this was a problem.

The cost of solar dropped by 90% between 2010 and 2020, and the cost of panels fell by 14% last year. Batteries were just straight up not a thing until 2019: California's grid-scale battery storage capacity has been doubling every year since then.

Putting together the solar panels, the battery, the desalination plant, and the brine plant, he's proposing a $42 billion dollar project that has only been economically feasible for a year or two now. I'm not surprised that it hasn't been built yet.
