What I've meant was mining on the wind mills themselves. So there would be no need of passing through the grid.
I heard that crypto mining hardware has to have decent-ish (80-90%) uptime to be profitable. That would make it infeasible to have it on standby waiting for excess energy on the grid.
The interesting question is what effect clean energy has to the usage of hydrocarbons. Will it bring reduce global demand or just reduce the price of energy. The good news is: CO2 emission intensity is going down globally and emissions per capita in US, China and EU28 are going down. The bad news are: Emissions per capita are still going up globally, and hydrocarbon usage and CO2 emissions are breaking records year a…
If they don't, there is so much demand for the stuff (burning it is so incredibly useful) that it'll all be burned.

As the production costs with windpower decrease due to the technological progress, the question of grid storage and grid interconnection becomes more pressing. E.g. in Germany, they frequently have days of negative energy prices, where producers need to pay to feed energy into the greed because of overproduction of energy on windy/sunny days [0](in German). Without storage and grid interconnection, there is only so m…
Isn't this where pumped storage and other forms of storage come into play? Here in Scotland we routinely pump water back up into our lochs in order to store it for future use. There's also various news articles reporting on German mines beginning to be used as pumped storage sites, with a reservoir on the surface, and water dropping into the mines below when there's sudden demand. This is a good problem to have, thou…
I think storage should be decentralized with towns/cities working to store locally and forward as required.
The future of mankind lies with nuclear power. I'm distressed by it not receiving as much attention as windmills.

It’s not about building up capacity alone: you want to take power off the grid at negative energy price times.
You are taking power off the grid: The power otherwise produced by the hydro plant. Of course with a lower reservoir, you can go into negative territory instead of "just" taking the plant down to 0.

three words, last one's shima.
oh, look at the time, it's 2018 already..

I think they're an efficient use of market based tools to ensure that the group who can reduce the input to the grid does so, and to incentivize electricity production that can meet the flexible demands of the grid (e.g. slow ramping coal would be penalised over fast ramping gas without any regulation needing to specifically target the coal and the coal plant can do anything it wants to improve this, e.g. fit batteries, since no technology is mandated.
