The Corporate Reality

Green Mountain Energy is NRG Energy’s environmental brand. Same parent as Reliant, Direct Energy, Cirro, and Discount Power. NRG bought Green Mountain for $350 million in 2010. Your premium funds renewable energy certificate purchases and NRG’s corporate overhead.

4Change Energy is Vistra Corp’s budget brand with a charitable giving angle. Same parent as TXU Energy and Veteran Energy. Vistra runs them through Value Based Brands LLC. The $1-$3/month charity donation is modest but real.

Both are Fortune 500-backed. The stability question is a draw.

What They Actually Sell

Green Mountain’s lineup (all 100% renewable):

• Pollution Free Conserve 12/24 at 17.5 cents/kWh
• Pollution Free e-Plus 12/24 at 17.8 cents/kWh
• Green Savings Plus 24 at 21.7 cents/kWh (includes $150 bill credit at 2,000+ kWh)
• Solar buyback (Renewable Rewards) with three tiers
• Go Local Solar plans sourced from specific Texas solar farms
• Green-e Energy certified (third-party verified)
• ETFs: $150 (12-month) or $295 (24-month)

4Change Energy’s lineup:

• Fixed-rate plans (6-24 months) with bill-credit structures
• Budget rates that often rank among the cheapest in Texas
• Maxx Select Green 12 (higher renewable content option)
• Standard plans include only 3% renewable
• $1-$3/month charitable donation to your chosen cause
• No solar buyback, no free nights, no specialty plans

The honest math at 1,200 kWh/month:

• Green Mountain at 17.5 cents: ~$210/month
• 4Change at budget rates: ~$150/month (varies by plan)
• Gap: ~$60/month, ~$720/year minimum

At Green Mountain’s highest rate (21.7 cents), the gap widens to ~$110/month or $1,320/year.

The Credit & Deposit Question

Both require credit checks. Neither offers prepaid.

Green Mountain: Soft credit check. Pass and no deposit. Fail and you’re looking at a deposit based on two months of estimated usage. No prepaid escape hatch.

4Change: Same credit check process. Same deposit requirement if you fail. No prepaid option.

If your credit is a concern, neither company helps. Look at Payless Power or Frontier’s prepaid option.

The Verdict

Choose Green Mountain if:

• 100% renewable energy with Green-e certification is worth $720-$1,320/year
• You want 29 years of green-only track record
• Solar buyback for rooftop panels matters
• 24/7 support and a 4.8-star rating on Texas Electricity Ratings matter

Choose 4Change if:

• Budget rates matter more than energy source
• You use 1,000+ kWh/month and want bill-credit savings
• You’d rather save $720+/year and donate to environmental causes directly
• Simple fixed-rate plans without green premium complexity sound right

The real question: Is $720-$1,320/year for verified renewable energy certificates the best use of your environmental budget? Green Mountain is legitimate. But that money could fund rooftop solar panels on your own house, which actually reduces grid demand.
