BTC providing demand for renewables stimulates the development of renewables. Any massive investment like in renewables carries a risk, and the higher the demand the lesser the risk for the investment on the supply side.
It's just a lie.
BTC provides demand for cheap energy not for renewable.
And it consumes the demand. It doesn't create this demand for others.
You use that peak energy to create heat, charge a battery or do similar things.
You can easily create hydrogen.
But using it for searching for a hash is the worst idea.
If you would be able to use the heat output sure that could work but let's someone do that first
Until then doing anything else with this energy is critit!
So you have two options really. Either partially sponsor your windturbin with bitcoins you'll mine with it or not build the turbin at all.
The current problem is not how to utilize every bit of excess energy. The current problem is where to get the money from to build capacity that will at time generate excess that is hard to transport away from the power station.
We already have plenty of renewable energy which is cost effective.
We don't need Bitcoin to balance this out.
And Bitcoin doesn't just consume the excessive energy, it consumes all of it as long as it is cost effective to consume it.
Not running your Bitcoin farm 24/7 is not effective.
Bitcoin is not supporting energy production.
