If the whole network could be powered by a single wind turbine then you would only need 1 other wind turbine to overpower it. Bitcoin is secure because it incentivizes investment in more power use by miners.

Bitcoin energy use is a positive thing for the environment: miners will always want to use the cheapest power = more renewables flexible load allows for grid reinforcement = no more blackouts

more energy = better for humanity to get more energy, we will create cleaner and better sources over time.

In Europe right now, because of their "green" policies shutting down cleaner natural gas and nuclear power, they are now burning more emergency COAL to meet winter demand.

you must unlearn what you have learned young padawan.
