Why is it that if you look at Sankey energy flow diagrams for each state (on llnl.gov), you ses that each state produces around the same amount of rejected electrical energy (about 60%) no matter if it is primarily hydro- or fossil-fuel-generated, which is far less efficient than hydropower or natural gas plants should be?
It's not actually rejected electrical energy, it's rejected heat energy which is why the diagrams uses BTU as an unit. Also, all states mainly uses fossil fuel generation (coal, LNG or oil) for their base-load services.
Is it wrong to interpret that data as representing a pervasive energy surplus, everywhere?
Yes, because rejected heat energy isn't a surplus - it's a measure of loss due to the inescapable second law of thermodynamics which plays the biggest role in conversion and transmission.
When you hear power lines humming, is it misinformation to say demand is less than supply and the electricity is trying to escape the wire into the air?
Yes, power lines always humm when in use but also because demand and supply must be balanced and when they aren't balanced you get things like voltage and frequency changes which introduces unnecessary wear and tear or even brown/black outs.
