Clean Energy Intelligence

We think you should understand exactly what you are backing, how it works, and why it matters.

Our white papers are written for anyone who wants to go deeper: prospective members, current members, and anyone who has read criticism of voluntary renewable energy markets and wants clear answer to the hard questions.

We publish them because we believe informed participation is real participation.

RECs Explained

SUMMARY Renewable Energy Certificates (RECs) are the market instrument behind every clean energy claim made in the United States. This paper explains how they work from first principles: why they exist, what they are, how they are issued and retired, and what role they play in the economics of the clean energy transition.

It also addresses the questions most providers are reluctant to answer directly, including the additionality question, the difference between RECs and carbon offsets, and what happens when biomass and combustion sources are included in a program that calls itself renewable.

WHAT IS COVERED  The grid problem that makes RECs necessary. What a REC is and what it is not. The five-stage lifecycle from generation to retirement. The economics of the voluntary market. Verification and third-party authority.

Voluntary Markets Matter, Especially Now

SUMMARY Federal clean energy policy is contracting. The most significant rollback of renewable energy tax credits since they were established was signed into law in July 2025. Billions of dollars in planned clean energy projects have been canceled. The policy environment that drove renewable energy development for two decades is no longer stable.

This paper explains why the voluntary market for renewable energy I can be structurally more durable than government support, and why individual participation in that market is different in kind from a tax credit or a donation.

WHAT IS COVERED How federal policy drove renewable energy development and why that foundation is shifting. The structural difference between policy support and market demand. Why a membership is not a tax credit or a donation. How collective backing moves markets.

The Questions We Get Most Often

.

Yes. There are no installation requirements, no property modifications, and no landlord permissions needed. If you pay an electricity bill or want to match your household energy usage with clean generation, you are eligible. Renters, apartment dwellers, condo owners, and homeowners are all welcome.

No. Your electricity service stays exactly as it is. Sustainable Choice operates entirely separately from your utility, matching your usage with clean energy through the certificate system, not through your electricity delivery. Your utility bill, your provider, and your service are all unchanged.

Sustainable Choice purchases and retires RECs at the membership level. The aggregate choices of our entire membership determines the volume and type of clean energy we source and retire.Individual members do not currently receive individually assigned certificates.

Your proportional share of those retirements is reflected in your dashboard. We are working to develop individually assigned certificates that will be delivered directly to each member. We will announce that capability when it is ready.

No, while both are used to reduce carbon footprints, they are used for different purposes and are not interchangeable.

Renewable Energy Certificates (RECs) and carbon offsets are not the same; they are distinct tools for sustainability.

Key Differences

  • Purpose: RECs fund renewable energy generation; offsets fund carbon reduction projects beyond electricity.
  • Scope: RECs only address electricity usage, whereas offsets can cover broader emissions. 

Compliance RECs are purchased by electric utilities to meet state Renewable Portfolio Standard requirements, which are legal mandates that a certain percentage of electricity sold must come from renewable sources. Voluntary RECs are purchased by individuals and organizations that choose to support clean energy beyond what is legally required. Sustainable Choice members participate in the voluntary market. We do not help utilities meet their legal requirements.
