could it be made profitable by incorporating green energy and focusing solely on mining crypto's.
Crypto mining operations, unlike most energy intensive ventures, is not geographically limited and can be established and run anywhere on earth with a decent internet connection. Being able to select location, most mining operations already opt for green energy providers such as hydroelectric power which provide electricity at lower cost per watt than coal based alternatives. In short, this means most miners already take advantage of low carbon footprint, green energy, alternatives rather than relying on oil or coal to provide energy. It could probably be acknowledged as an industry standard.
The biggest gains in crypto mining are likely to come from samsung, nvidia and intel entering the ASIC market which should help to decentralize mining operations, reduce the cost of mining as well as increase hash rate while reducing watt consumption per hash as silicon etching processes switch to smaller nanometer scale.
