It will certainly be better with Proof of Stake & sharding, but I was curious how bad it is today, so I looked it up. One ETH transaction consumes 86.94 kWh of energy. Wikipedia says gasoline has 8.83 kWh/l energy content, so it looks like about 10L of gasoline per transaction (not 10gal). Still, there are about 3.8L/gal, so if you factor in that heat engines are about 25% efficient, then you are right. What a crazy world we live in. https://digiconomist.net/ethereum-energy-consumption https://digiconomist.net/ethereum-energy-consumption
