beginning: the player thinks that the bar represents energy consumption (linear correlation with energy consumption)
later: the player thinks that the bar represents energy output (diminishing returns with increased energy consumption up until there is no energy output)
In the long term, preserving ecosystems maximizes energy capture and consumption. There is no duality between ecosystem/environment preservation and maximizing energy consumption. Energy consumption and output are not the same thing since efficiency and diminishing marginal returns result in decreased energy output per energy consumption.
