Energy FUD (Fear, Uncertainty, Doubt) surfaces when skeptics highlight Bitcoin’s electricity consumption as inherently wasteful, ignoring that miners often locate where energy is cheapest, frequently near surplus hydro or wind power. Critics also overlook how mining can spur renewable buildouts or stabilize grids by absorbing excess energy.

While valid environmental concerns exist if mining relies on fossil fuels, the conversation is more complex than ‘Bitcoin = bad for environment.’ Supporters counter that the costliness of proof-of-work is what secures the network. They argue PoW’s energy use is a feature, not a bug, aligning security with economic incentives and the broader transition to sustainable energy sources.
