Because AI and Crypto use so much electricity, what if a law was made that they had to power it with green energy?

Something on the lines of if your company facility is using over X amount of energy the majority of that has to be from a green source such as solar power. What would happen and is this feasible or am I totally thinking about this wrong

Edit: Good responses from everyone, my point in asking this was completely hypothetical, ignoring how hard it would be to implement a restriction. My own thoughts are that requiring the use of renewable energy for high electricity products could help spur the demand for it as now it's a requirement. Of course companies would fight back, they want money
