There are states in the US where it's illegal to collect rainwater.

In the UK, it used to be legal to buy solar panels and mini windmills, but less than 4% of the country allowed them to be put up. This was back when Blair was PM. We got a punishment "green" tax for not going green enough, despite the law not allowing us to go green.

White goods (big appliances) tripled in price due to this tax.

Solar panels are bloody useless where I live as they cost more than they generate. I will need just over 32 years to get my money back.

I still can't have a mini windmill, due to the law, despite that it would save me tons of cash and produce tons of electricity in wind as fuck north eastern Scotland.
