Your choices do not exist in a vacuum. Earth is an interconnected community of living and non-living things says ethicist Patrick Effiong Ben of the University of Manchester. African philosophers like Jonathan Chimakonam and Aïda Terblanché-Greeff have a helpful concept for thinking through the weightiness of your decisions: complementarity.
These are some really great points. This to me is a reflection of our (in particular US) view that energy is something unlimited and cheap. The idea that we might simply do less or optimize to anything other than profit is laughable to most folks, so efficiency barely enters the conversation except as a means to profit further in some niche cases after the fact. The organizational changes required to correct the issues you identified seem truly insurmountable, unfortunately, but you’re absolutely right.
