Negative Public Perception of Crypto Mining – Questions About power

TL:DR – I'm environmentally conscious and don't want to contribute to negative perception of crypto. Wondering if advancements in RVN mining algos can make it more efficient, helping me hit the power targets I have with ETH.

I was making my rounds on Reddit today and came across this post, started reading through the comments.

I knew that gamers were mad about GPUs being sucked up for mining, especially during chip shortages etc… But I didn't know they were "the government should completely ban all crypto" mad. I've only been mining for a few months and a lot of the things they mention in that thread have been on my mind.

I'm mining on 3x 1080s and 2x 1080TIs, all of which I already had for work as a 3D artist. So I haven't been buying up hardware (probably more justifiably annoyed than gamers because I need some new RTX cards for work and can't get them). I care about the environment and tune exclusively for efficiency with my rigs. Also planning on putting together a solar setup to mine with sometime this year. Personally I don't want to contribute to negative perception.

This whole thing has me wondering about my future with RVN, because in my experience it's been considerably less power efficient than mining ETH. Something like twice the power for half the income. Mining RVN just doesn't respond to my system tuning in the same way.

Can any miners with more experience tell me if it's likely that mining software updates could eventually increase the speed or efficiency of mining RVN? Thinking toward life after ETH I'd like to still be profitable, but it's also important to me that I'm sustainable. Not sure how much I can justify considering the wattage requirements.
