How This Was Decided
These companies are featured based on what matters for this category:
- Does the company own generation or just buy RECs? (we checked)
- What % of their plans are 100% renewable vs 'contains some renewable'
- Green-e certification or equivalent third-party audit
- Price premium over standard plans (should be under 2 cents/kWh)
- Solar buyback rate if you have panels
No bias. Same treatment for every company.
