Bottom Line: Green Mountain costs $200-$400/year more for genuine renewable sourcing. 4Change offers budget rates plus tiny charitable donations. Choose based on what matters: environmental infrastructure or personal savings.


The Short Answer

Both companies want you to feel good about your electricity bill. They take different approaches.

Green Mountain: Pay $200-$400/year extra. Your premium funds actual Texas wind farms and solar installations through direct contracts.

4Change: Save money on budget rates. They’ll donate $1-$3/month to your chosen charity. You keep the other $15-$30/month you’d have paid Green Mountain.

The math is clear: 4Change’s charitable donations are a rounding error. Green Mountain’s renewable investment is substantial. But 4Change saves you real money.

Overview

Green Mountain Energy pioneered Texas renewable electricity in 1997. Every plan is 100% renewable, sourced directly from Texas wind farms and solar generators. NRG Energy (NYSE: NRG) owns them. You’re paying a premium for 27 years of environmental credibility.

4Change Energy is a budget provider with a marketing angle: they donate a small portion of your bill to charity. Tri-Eagle Energy (a Just Energy subsidiary) owns them. The charity component is mostly marketing—$1-$3/month on a $150 bill is 1-2%.

The Price Reality

Average Texas household: 1,200 kWh/month

Green Mountain rate: 12-14 cents/kWh (typically) 4Change rate: 9-11 cents/kWh (typically)

Monthly difference: $20-$35 Annual difference: $240-$420

That’s the trade-off. Green Mountain gets your extra $300/year and invests it in renewable infrastructure. 4Change keeps your rates low and donates $12-$36/year to charity.

The Feel-Good Factor: Real Numbers

Let’s be honest about what each company accomplishes.

Green Mountain’s impact:

  • Your $300/year premium funds direct wind farm contracts
  • Supports actual solar installation partnerships
  • 27 years of environmental investment track record
  • Legitimate renewable energy infrastructure funding

4Change’s impact:

  • Donates $1-$3/month to your chosen charity
  • Annual charitable contribution: $12-$36
  • You could donate $200+/year yourself from savings and do more good

The honest math: If charitable giving matters, save $300/year with 4Change and donate $200 yourself. You’d give 5-10x more to causes you choose.

If renewable energy infrastructure matters specifically, Green Mountain’s direct investment model beats cash donations to random charities.

Green Energy Options

Green Mountain wins decisively.

Green Mountain:

  • 100% renewable on every plan—no exceptions
  • Direct contracts with Texas wind farms
  • Sources from actual solar installations
  • Can document exactly where your electricity comes from
  • Your premium funds new renewable infrastructure

4Change:

  • Offers 100% renewable plans as an option
  • Uses Renewable Energy Certificates (RECs) like most providers
  • Green plans available but not the focus
  • Budget rates remain the priority

If you choose 4Change’s green plan, you’re getting the same certificate-based offsetting that TXU sells. Green Mountain’s direct sourcing is genuinely different.

Company Stability: A Real Concern

Green Mountain wins on corporate backing.

Green Mountain: NRG Energy (NYSE: NRG) owns them. Fortune 500 company. $30+ billion market cap. Zero financial concerns.

4Change: Tri-Eagle Energy owns them, which is a subsidiary of Just Energy. Just Energy went through CCAA bankruptcy in 2021. They restructured and continue operating—PUCT verified their financial stability—but bankruptcy history is bankruptcy history.

If corporate stability matters to you, Green Mountain’s NRG backing is more reassuring than 4Change’s Just Energy parentage.

Customer Service

Green Mountain wins by default.

Green Mountain:

  • Phone wait times: 10-15 minutes
  • Staff understand renewable energy
  • Website works, nothing fancy
  • No 24/7 support

4Change:

  • Phone wait times: 25-40 minutes during peak periods
  • Website pays bills, shows usage, that’s it
  • No proactive communication
  • No 24/7 support

Neither company invested heavily in customer service, but Green Mountain is noticeably less painful to deal with.

The Verdict

Choose Green Mountain if:

  • Genuine renewable energy infrastructure is worth $200-$400/year
  • You want 27 years of environmental track record
  • Direct wind/solar contracts matter more than charity donations
  • Corporate stability (NRG backing) matters to you

Choose 4Change if:

  • Budget rates matter more than energy source
  • You’d rather save $200+/year and donate directly to causes you choose
  • The charity angle makes budget shopping feel better
  • The Just Energy bankruptcy history doesn’t concern you

The honest take: Green Mountain’s renewable investment is real. 4Change’s charitable donations are a marketing angle on a budget provider. Pick based on what you actually value: renewable infrastructure funding or maximum savings with a feel-good garnish.
