Both sell "green" plans. But "green" in Texas electricity means they buy renewable energy credits—it's accounting, not physics. Your electrons come from the same grid as everyone else.

More options = more ways to optimize, but also more ways to pick wrong. If you just want simple fixed-rate power, ignore the complexity.
