Every major Texas electricity provider now offers a “green” or “100% renewable” plan. That sounds great until you realize what “100% renewable” actually means in most cases: the provider bought paper certificates to offset your fossil fuel usage. The same coal and gas power still flows to your house.
This isn’t necessarily a scam. But there’s a wide spectrum between genuine renewable energy investment and slapping a green label on an otherwise standard plan. Understanding where your provider’s green energy plans fall on that spectrum matters if you actually care about your environmental impact.
How “Green” Electricity Works in Texas
You can’t choose which electrons reach your home. Electricity from wind farms, natural gas plants, coal plants, and solar farms all flows into the same grid. When you flip a light switch, the power came from whatever mix of sources was generating at that moment.
So what does a “green” plan actually do?
Renewable Energy Certificates (RECs)
Most green plans work through Renewable Energy Certificates. Here’s the process:
- A wind farm in West Texas generates 1 megawatt-hour of electricity
- That electricity goes into the ERCOT grid
- The wind farm also receives one REC—a certificate proving 1 MWh of renewable electricity was generated
- Your electricity provider buys that REC
- The provider credits the REC to your account
- Your plan is now “100% renewable”
The electricity that actually reaches your home is still the standard grid mix (about 40% natural gas, 30% wind, 15% solar, and the rest from coal and nuclear as of 2026). But mathematically, enough renewable electricity was generated somewhere in Texas to “match” your usage.
The REC Market
RECs trade on an open market. Prices fluctuate based on supply and demand, but in Texas—where wind and solar are abundant—RECs are cheap. A provider can buy enough RECs to label a plan “100% renewable” for less than a penny per kWh.
This means the green premium you pay (typically 0.5-2 cents per kWh) mostly covers the REC cost plus margin for the provider. Some of that money flows back to renewable energy generators, but it’s not the same as directly building new wind turbines or solar panels.
The Greenwashing Spectrum
A “100% renewable” label from one provider might mean a $0.003/kWh paper purchase; from another, it funds a brand-new solar farm. Four levels separate genuine green investment from marketing theater.
Level 1: REC-Only Plans (Most Common)
The provider buys RECs on the open market to offset your usage. The RECs might come from wind farms that were built 10 years ago and would exist with or without your plan.
What it means: Your money supports existing renewable infrastructure, marginally. It doesn’t create new renewable capacity.
Who does this: Most major providers’ basic green plans, including some offerings from Gexa Energy and Reliant Energy.
Level 2: New Renewable Matching
The provider commits to matching your usage with RECs from newly built renewable projects (built within the last 2-3 years). This means your subscription helps justify the financial case for building new capacity.
What it means: Your money has a stronger connection to new renewable development.
Who does this: Chariot Energy matches usage with solar from their own farm portfolio. Rhythm Energy sources from 100% renewable projects.
Level 3: Direct Ownership and Investment
The provider owns or directly contracts with specific renewable facilities. They can tell you exactly which wind farm or solar farm generated your electricity equivalent.
What it means: Maximum transparency and impact. Your subscription directly funds specific renewable projects.
Who does this: Green Mountain Energy was the first company in Texas to sell exclusively renewable electricity and has direct purchase agreements with specific wind and solar facilities.
Level 4: Local/Community Solar
Some providers offer plans connected to specific local solar installations. Your subscription directly funds panels in your area, and you receive credits for the electricity they generate.
What it means: The most direct impact—you can sometimes visit the solar farm that’s generating “your” electricity.
Who does this: Chariot Energy specializes in community solar models in Texas.
How to Evaluate a Green Plan
Four questions separate a worthwhile green plan from an overpriced sticker.
Question 1: Where Do the RECs Come From?
Ask the provider (or check the EFL) whether RECs come from:
- National market: Cheapest RECs, least impact. Could be from a decade-old wind farm in Iowa.
- Texas market: Better. Supports the state’s renewable infrastructure.
- Specific facilities: Best. The provider can name the wind or solar farm.
Question 2: Are the RECs from New Projects?
RECs from existing projects that would run regardless don’t create new renewable capacity. RECs from projects built in the last 2-3 years (“new vintage”) mean your subscription contributed to the financial case for building them.
Question 3: What’s the Actual Green Premium?
Compare the green plan’s rate to the provider’s equivalent non-green plan. If the difference is 0.5 cents per kWh, the provider is spending very little on RECs. If it’s 2+ cents per kWh, they’re either buying higher-quality RECs or pocketing a larger margin.
At 1,000 kWh monthly usage:
- 0.5-cent premium = $5/month ($60/year)
- 1-cent premium = $10/month ($120/year)
- 2-cent premium = $20/month ($240/year)
Question 4: Does the Provider Walk the Talk?
Look beyond the plan:
- Do they invest in renewable infrastructure?
- Do they have carbon neutrality goals for their own operations?
- Are they transparent about their energy sourcing?
- Do they publish annual sustainability reports?
Green Mountain Energy has been exclusively renewable since 1997 and publishes detailed sourcing reports. Compare that to a provider that sells mostly fossil-fuel plans and tacks on a “green option” for marketing purposes.
The Major Green Providers in Texas
Three providers stand out for backing their green claims with real infrastructure, not just bulk REC purchases.
Green Mountain Energy
The original green electricity company in Texas. Founded in 1997, they’ve sold exclusively renewable energy from day one.
Strengths: Long track record, transparent sourcing, 100% renewable by default (not an add-on), direct power purchase agreements with specific wind and solar facilities.
Trade-off: Rates tend to be 1-3 cents higher than the cheapest non-green plans. You’re paying for genuine renewable commitment, but it’s not the cheapest electricity available.

Chariot Energy
A solar-focused provider that owns and operates solar farms in Texas. They offer community solar plans where your usage is matched to production from specific local installations.
Strengths: Direct solar farm ownership, community solar model, transparent about which facilities generate your power, competitive rates that often match non-green plans.
Trade-off: Smaller company with less brand recognition. Service area covers major TDUs but may be limited in some regions.
See how they compare: Gexa vs Chariot
Rhythm Energy
Offers 100% renewable plans sourced from Texas wind and solar. Known for transparent, no-gimmick pricing.
Strengths: No base charges on many plans, renewable by default, straightforward pricing without bill credits or minimum usage fees.
Trade-off: As a newer market entrant, they have a shorter track record than Green Mountain or the legacy providers.

The Cost of Going Green
How Much More Does Green Electricity Cost?
Five years ago, going green meant paying 5+ cents more per kWh. That premium has collapsed. Wind and solar are now the cheapest sources of new electricity generation in the state. That means green plans are sometimes competitive with—or even cheaper than—fossil-fuel plans.
Typical green premium: 0-2 cents per kWh above the cheapest available non-green plan At 1,000 kWh/month: $0-20 extra per month
Some providers, particularly Chariot Energy and Rhythm Energy, offer green plans at rates comparable to standard plans because their input costs (solar and wind) are inherently low.
Is the Premium Worth It?
That depends on what you’re buying. If the green premium goes toward:
- New renewable capacity: Yes, you’re funding the energy transition
- Old RECs from existing projects: Maybe. You’re supporting the REC market but not building new capacity
- Marketing margin: No. You’re paying for a label, not impact
Ask the provider directly what the premium funds.
Red Flags: How to Spot Greenwashing
One quick test: ask the provider to name the specific facility generating your electricity equivalent. If they can’t, keep reading.
”100% Clean Energy” with No Details
If a provider claims 100% renewable but can’t tell you where the RECs come from, what vintage they are, or which facilities generated the equivalent electricity, they’re probably buying the cheapest available RECs and calling it green.
Green Plan Costs the Same as Standard
If the green plan costs exactly the same as the non-green plan, the provider is either eating the REC cost (unlikely) or the RECs are so cheap as to be meaningless (more likely).
Vague Environmental Claims
Watch for language like “committed to a cleaner future” or “supporting renewable energy” without specifics. Real green providers cite exact percentages, specific facilities, and measurable goals.
Carbon Offset Claims Instead of RECs
Some providers claim “carbon neutral” plans through carbon offsets rather than RECs. Carbon offsets (like paying to plant trees) don’t guarantee any renewable electricity was generated to match your usage. They’re a different mechanism entirely and can be of questionable quality.
Texas’s Renewable Reality
Texas produces more wind energy than 46 countries. The state’s renewable capacity dwarfs every other U.S. state:
- Wind: Texas leads the nation with 40,000+ MW of installed wind capacity
- Solar: Rapidly growing with 20,000+ MW installed
- Grid mix: About 30% wind, 15% solar, and growing
This means two things for green electricity buyers:
-
RECs are cheap because Texas produces a surplus of renewable energy. The financial case for buying cheap RECs is weaker here than in states with less renewable capacity.
-
Your grid electricity is already partially green. Even on a standard plan, roughly 45% of the electricity flowing through Texas wires comes from renewable sources. A “100% renewable” plan covers the remaining 55% with RECs.
The Bottom Line
If you want green electricity in Texas, you have real options—not just greenwashed labels. The key is knowing what you’re buying.
Genuine green: Providers like Green Mountain Energy and Chariot Energy that own or directly contract with renewable facilities and can show you exactly where your electricity equivalent comes from.
Good enough green: Providers that buy Texas-sourced, new-vintage RECs. Your money supports the state’s renewable market even if it doesn’t fund specific projects.
Green label only: Providers that buy the cheapest available RECs from anywhere, slap a green badge on the plan, and charge you 1-2 cents extra for the privilege.
Ask questions. Check the EFL. Look for transparency. The greenest plan isn’t always the one with the biggest marketing budget.

Frequently Asked Questions
Does green electricity actually come from renewable sources?
Not directly. All electricity on the Texas grid comes from a mix of sources (natural gas, wind, solar, coal, nuclear). When you buy a green plan, your provider purchases Renewable Energy Certificates (RECs) to match your usage with an equivalent amount of renewable generation somewhere on the grid. You get the same physical electricity as everyone else.
How much more do green electricity plans cost in Texas?
Green plans typically cost 0-2 cents more per kWh than standard plans. For a household using 1,000 kWh per month, that’s $0-20 extra. Because Texas has abundant wind and solar, the green premium is smaller here than in most states. Some green providers offer rates competitive with standard fossil-fuel plans.
What are Renewable Energy Certificates (RECs)?
A REC is a certificate proving that 1 megawatt-hour of electricity was generated from a renewable source. When a wind or solar farm generates power, it produces both electricity (which goes to the grid) and RECs (which can be sold separately). Electricity providers buy RECs to label plans as “renewable” or “green.”
Which Texas electricity company is the greenest?
Green Mountain Energy has the longest track record (since 1997) of selling exclusively renewable electricity with direct purchase agreements from specific facilities. Chariot Energy offers direct community solar connections. Rhythm Energy sources from 100% renewable projects. The “greenest” depends on whether you value track record, transparency, direct solar ownership, or overall impact.
