it seems at the present time mining bitcoin alterrnative have to use force, such as mine the use of solar power, among ordinary power that is often used and solar power or other alternative power of these three are most profitable to mine half day bitcoin in this era?
if you really want to go green mini hydro generator is the way to go, but you need the correct place to use that, not many can, i would avoid solar as they cost too much and you need many of them just to cover one miner
for example to cover one miner that consume 24kwh a day, which is almost 9000khw per year, you need already 9kw of panels(a 1000watt of panel cover only 1000kwh a year), that look too expensive just to save the consumption of one miner
