Green Energy Plans in Texas — 100% Renewable Electricity Explained

5 minute read · Renewable energy

Texas generates more wind energy than any other state — more, in fact, than most countries. That abundance means Texans have access to genuinely competitive renewable electricity plans, and in many cases, going green doesn't cost a premium at all.

But "100% renewable" plans require some explanation. Here's what they actually mean, how the renewable certificate system works, and what to look for when choosing a green plan.

Does a green plan send you "clean" electricity?

Not exactly — and it's important to understand why. The ERCOT grid delivers electricity from hundreds of sources simultaneously: wind turbines, solar panels, natural gas plants, and nuclear reactors. The electrons that flow to your home are a mix of all of them. There's no separate "green wire."

When a provider offers a 100% renewable plan, they're doing something slightly different: they purchase Renewable Energy Certificates (RECs) equal to 100% of your consumption. Each REC proves that 1 MWh of electricity was generated from a renewable source somewhere on the grid. Your bill payment funds that renewable generation.

Types of green plans in Texas

Not all green plans are structured the same way. Here are the main categories:

• 100% wind — the most common type in Texas. REC purchases are matched to wind generation, often from Texas wind farms. Typically the most price-competitive green option.
• 100% solar — RECs sourced from solar generation. Solar plans sometimes command a small premium over wind plans due to supply constraints, though the gap has narrowed significantly.
• Blended renewable — a mix of wind, solar, and other qualifying renewables. Often used to optimize cost.
• Community solar — less common in Texas; connects you to a specific local solar project rather than purchasing RECs on the open market.

Are green plans more expensive?

In Texas, often not — or barely. Because the state produces so much wind energy, Texas RECs are among the least expensive in the country. Many wind-backed plans are priced within 0.5¢/kWh of standard plans, and some are cheaper.

When comparing green plans, use the same approach as any plan: look at the total effective rate at your actual usage level, not just the headline. A green plan at 10.5¢/kWh beats a non-green plan at 11¢/kWh on both price and environmental impact.

What to check on the EFL

Every green plan in Texas is required to disclose its renewable content on the Electricity Facts Label. Look for:

• The percentage of electricity from renewable sources (look for 100%)
• The renewable fuel mix (wind, solar, or blended)
• Whether RECs are sourced locally (Texas) or from out-of-state generation
