Q: Which is better for green energy, Constellation or Energy Texas? ▼
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. Want to know which has renewable generation backing versus just buying paper credits? Gexa has NextEra (the largest renewable generator in the US) behind them. Most others just buy credits. That's the difference.

If you just want simple fixed-rate power, ignore the complexity. If you have specific needs (EV charging at night, pool pump, work-from-home AC), the right specialty plan can save you $50/month.
Q: Which is better overall, Constellation or Energy Texas? ▼
