You said that at the best case you were 5 times higher cost than it being profitable.

I stated that actual electrical wholesaler prices are regularly below 5c per kWh. In actually practice they are often negative for a large part of the day where I live due to solar feed in.

By financially profitable not being the same as actual profit I assume that means the cost of capital and maintenance? Which is why I said that it could make sense for idle computing capacity.

I don't know what you mean by subsidised? This is wholesale prices.

What I am saying is that the returns are close to the marginal cost of production.
