That's not exactly how it works.

Hmm... so let's try another (likely absurd) approach:

What about: the government promises bitcoins mined with solar energy will be free of tax. Solar panels bought for mining bitcoins will be half-subsidized by the govt. For the next two years, at least.

Huge solar farms spin up as everyone wants to mine as much as they can on cheap energy. Two years pass, govt says it's end of the Bitcoin subsidy; miners fold, cheap used solar panels flood the market...
