Reply to comment by Jnorean in HVDC macrogrid would reduce climate pollutants and electricity costs while transmitting low-cost renewable power by manual_tranny

Well, no. You can't put 800kv in the outlets. Instead, you'll go 800kv HVDC -> 600kv AC > 70kv AC > DC > 50kv AC 50hz then feed it onto the existing grid for further stepping down. DC to AC and the other way around is expensive, but all your electronics already go both ways because it's the easiest way to transform voltage now.
