They certainly exist. There was a Dutch guy in another post bragging about his micro-nation being 100% emissions free because he kept seeing his government bragging about being "100% green energy," while the supermajority of their electricity was generated with natural gas (being the only significant fossil fuels they had and it being relatively easy to source from neighbors)

The point isn't there was one guy who fell for it, the point is there will be people mistaking natural gas for actual green energy instead of just being less harmful, or being unaware of what's actually producing their electricity simply because there is a deliberate effort to mislead people about it by, among other things, conflating terminology like "green" and "emission free."
