Each wind turbine gear box requires about 60-300 gallons of oil. Also some of the newer oils last 10 years.
That’s correct— I read about 12 articles and Rich gave different numbers - Wind Farms are typically about 150 Turbines & that’s where my brain stuck in the 1,000’s. I’m not at all sure thst they have found any of the new Oil Blends that give that much longevity— but that is the goal. The issue is leaks in the Gear Boxes, it’s not that oil wears out — it’s water in the gear box. More than just the gear box requires lubricant, but it is the largest amount.

I read it and explained my error. There are several sizes of Turbines and some of them have been around for 40 years. Regular Maintenance is key & there are some problems with that.
Overloaded electrical grid and democrats want to try to ban natural gas stoves and now central heat. How long before they go after water heaters and emergency generators?
Do you remember when Barack Obama said he would like to raise the price of electricity.? How would you do that? Getting rid of all other alternatives and having to rely on electric and the price would go sky high. No natural gas. No drilling for oil. Take a look at what's going on in Europe. They went green and now they have to pay three or four times more to stay warm . https://www.politico.com/story/2012/...cket.%E2%80%9D
The other nice thing about hot water radiators or wall panels is they are nearly silent in addition to the no dust blowing advantage. The 40 unit apartment building I live in has a big heat exchanger tank in the basement. The heat exchange is connected to centralized steam heating system pipes from the main street. The hot steam generated at the city power & steam plant is what heats the water in the basement heat exchanger, so there is no gas furnace needed in the building. It is extremely low-tech and also highly efficient with almost no moving parts.
That's great for a 40 unit apartment building. I have a question. DD lives in an old building with radiators. Heats great. But she can't turn it off. Half the time her window is open in the dead of wintering NYC. It was that way in 3 different buildings she has lived in.
What about heat in an 1800 ft house built on a slab. Where does one put that boiler?
Huh? I grew up with steam radiators and can't think of any maintenance being done on them. Heck, some were nearing 100 years old when my parents sold that house. I would say they were far superior to a forced hot air system that I had in some of the houses I've owned since.
The last house we lived in with radiators had to have them bled weekly to purge air from the system. I won't own a house with radiators. Fortunately that's not a problem in Texas, where they are rare.
Where did the article say anything about banning gas furnaces?
I don't know that I fully support making 95% the minimum efficiency so quickly, since it seems the more efficient, the less reliable they seem to be. (I didn't know they still sold 80% efficient furnaces, but I'm not in the market, yet) But, that's very different from an outright ban.

That sounds like the heating system needed repair, not an inherent flaw with radiant heat.

Maybe NYC should offer building owners some kind of tax incentive to install valves on old radiator systems like that, so that each radiator has its own control. But, I'm not an engineer, and don't know much about those old systems, to know if that would cause a problem, somehow.

I was wondering that myself.
