The money would be returned in the same way as a tax return is. It could either be in the form of a fixed amount that everyone gets, or could have some proportionality to income. The wonks will figure out if ‘everyone’ means all homeowners, all citizens, all taxpayers, or something else. It’s my sense that the best system would find a way to give refunds to everyone paying energy bills, whether they be renters, business owners, or… whatever else.
