There are some involving gas, the energy that comes from burning and isn't resold. There are a number of ways.
What is energy? It can be stored in a battery and can also take the form of money or value. There are examples where people wonder if they can take unused or waste energy to create value and then potentially reuse that value to purchase more energy or to use it for something else. Energy generally has a value, which helps in purchasing something else or creating things and so on.
So we use cryptocurrency, other proofs of work or other blockchains to reuse the energy that would normally be wasted to create value. Then we reuse that value in the economy. That creates considerable potential for the economy and the government. We can see that certain governments are involved in mining to create value using energy for the benefit of their citizens.
