For the green side:
I feel it's going to have 0% effect.
Ignoring what many people are saying, 'greener' note not green just greener methods of energy production are springing up all over.
And ignoring what the loud people are screaming bitcoin mining really does not use that much energy.

For the tax side:
The 15% tax is a boogeyman. Taxes are good. That is what a lot of people don't talk about. Companies and people sit on their money and watch it grow.
Governments SPEND money. Keeping it moving. The more they spend the more businesses and people get. The more they get the more the government taxes them. Which the government spends again. It's like the circle of life.
