In fact, most solar farms, wind turbines, hydrodams, are not very environmentally friendly due to the fact that they will also contribute to the diminishing ecosystem or the production involves processes that are not carbon neutral.
They are very environmental friendly. Accounting for the carbon cost from production, installation, and lifetime operation, they produce over 20 times less CO
2 per kWh of energy generated than the most efficient coal plants. It is now at the stage where it is more environmental friendly to build new solar panels from scratch than it is to continue to run existing coal plants. The efficiency of solar panels and other renewable sources is continuing to increase over recent years, so these numbers are only going to become more marked over the coming years.
Yes, their production is not carbon neutral yet, but they are significantly better than oil, coal, gas, etc.
I'll also add a quote from CoinShares, from a different report to the one I linked above:
Overall, our findings reaffirm our view that Bitcoin mining is acting as a global electricity buyer of last resort and therefore tends to cluster around comparatively under-utilised renewables infrastructure. This could help turn loss making renewables projects profitable and in time — as the industry matures and settles as permanent in the public eye — could act as a driver of new renewables developments in locations that were previously uneconomical.
