Pretty sad to see so many people hate on proof-of-work. I can only assume it's because they have read shallow articles that tell them "Bitcoin uses X amount of energy therefore it must be bad, because using energy is bad" or something along those lines. It's not so simple.

Proof of work solves issues like: - What to do with electricity before the generating source is connected to the grid

- Reduces carbon emissions by incentivising the burning of methane gas (20x worse than CO2)

- Makes it more viable to research new energy sources by lowering the cost.

- Acts as a load-balancer for the grid and makes it way more stable. This in turn means that we can build out huge amounts of solar and wind that rely on the weather.

Of course there are situations where Bitcoin is mined using non-renewable sources but if you believe that Solar and Wind are so cheap, then that issue will sort itself out, no? And it won't take long.

If you're an environmentalist and you want to solve the global issue of CO2 emissions, Bitcoin (and PoW) is a very very valuable tool. Don't throw it away because of a faulty belief.
