Bitcoin network should be sustained by distributed renewable energy

Bitcoin network should be sustained by distributed renewable energy, both sides have advantages.
Miners save money from the electricity bill and the plant doesn't need to be connected to the grid. Desired side effect? Reducing carbon footprint of the planet.
It's the perfect marriage.

I already have a 6kw photovoltaic power plant grid connected, obviously it's useless for my miners when sun is not shining.
I have 3 project in mind for the new year, money and time permitting:

• Another 6 kW photovoltaic power plant with 20kWh battery accumulation system. This isn't really autonomous because it's over my house, so it automatically switch to grid power if battery drawns. Anyway all the producted energy is used by 1kWh miners, it's about 6600kWh/year @Milano, Italy. With local tarif it's a saving of  1500 eur. The plant costs about 12k eur but gives a tax saving of 50% in 10 years. With this condition the investment is repaid in about 6 years
• 400W wind turbine with X kwh battery accumulation system and wind-adjustable miner. This is a test system for something bigger, i haven't wind data for the designed location, but i know it's a windy place. Need to determine battery size also leveraging miner could be turned off in case of no wind. For eolic good location could be remote offshore area otherwise impossible to phisically connect to the grid
• 1kWh idraulic turbine, like others i have the location, but using public water from the small river needs permission. This is the most remote at the moment

Available for any question or criticism.

I agree that environmental friendly sources of energy should be used when possible for anything that consumes electricity, but that's just because it is the right thing to do.

Bitcoin itself does not need to get into the politics of what kind of energy people should use, that's beyond its scope.

I agree, there is no best energy source at all and miners could use what they want to power their miners.
Anyway there are good spot for one kind of energy, just hoping to inspire someone thought like: "I have a south oriented roof" or "there is a small river near my nanny house" or "my balcony is a windy place".
I am absolutely not saying: "hey guys let's choose best energy for bitcoin"

Bitcoin needs a small self contained solar unit that acts as a miner and a wireless relay that can be placed atop telephone poles and high up in trees.

Make it so.

Yeah it's nice. But unfortunately, small and photovoltaic are not really friends.
For example a single 250W panel is about 1.5 square meter and in 1 year in my condition generate about 280kWh, that is an average of just 33W over the year.

Wind and specially Hydro produce more energy with the same nominal power in good condition
