Bitcoin doesn't need high transaction volume to provide value to its users, which is obviously apparent by looking at the current transaction volume. PoW is also the most efficient way to do what Bitcoin is doing. Attempts to displace PoW have all failed, because the required trade-offs are always too high, and detract from the value of the network. If you can figure out a fair way to seed value on a network that doesn't require burning energy, then please let the people know, and your new magic cryptocurrency will dominate the crypto-ecosystem overnight. No one would love that more than me. I could talk for hours about the various ideas people have had in the past, and why they failed, but I don't think this is the right place for that rant. It's also important to recognize that there isn't a single watt of PoW power that's wasted. The power utilized reflects exactly amount of value that Bitcoin is providing to the world. Satoshi also made the mining rewards get cut in half every 4 years, so the value to power usage ratio gets better and better over time. I could also go on about how mining facilities overwhelmingly are using excess power produced almost entirely from clean power sources. If the goal is reducing carbon emissions, there are so many serious offenders that are massively more wasteful.
