Vermont generates 100% of its electricity from renewable sources
According to the U.S. Energy Information Administration (EIA, 2025 generation data), Vermont leads the nation with 100% of its electricity generated from renewable sources, hydropower, wind, solar, geothermal, and biomass combined.
- 82% average of the top 5 states

Renewable share = hydro + wind + solar + geothermal + biomass net generation ÷ total net generation (EIA 2025).
This 2025 ranking sorts states by renewable share of net generation from EIA data. It sums hydropower, wind, solar, geothermal, and biomass, then divides by total net generation. Each result links to a full energy profile; read our methodology for the calculation and its limits.

What a renewable share shows
Renewable share shows the composition of reported in-state generation for the selected year. It does not measure a state's consumption mix, utility price, emissions lifecycle, or the cause of any state ranking. Use the linked profile to inspect the reported generation values alongside the rate and multi-year series.
Why renewable share is not the same as clean consumption
This ranking measures generation, the electricity produced inside a state, not the electricity its residents consume. It therefore should not be read as a consumption or grid-import measure. Read the renewable share alongside the absolute generation shown on the state profile rather than treating the percentage as a complete energy footprint.
How to compare releases
A ranking can move when renewable or total generation changes between annual releases. Compare the multi-year series on a state profile rather than inferring future capacity, policy, or weather effects from a single snapshot.

Frequently asked questions
Which state generates the most renewable electricity?
Vermont leads on renewable share at 99.9% of its net generation. Renewable share measures generation mix, not how much a state consumes, so a small state that exports clean power can rank at the very top.
Does a high renewable share mean cheaper electricity?
Not necessarily. This ranking measures the share of generation from selected renewable sources; it does not measure a utility tariff or identify what causes a state rate. Compare the two reported measures without assuming one predicts the other.
What counts as renewable here?
This ranking sums conventional hydropower, wind, solar, geothermal, and biomass net generation and divides by total net generation. It is a generation-mix measure based on EIA data, not a consumption or capacity-factor measure, and it does not include nuclear, which is carbon-free but not renewable.
Every figure on RateWatt is rendered directly from official U.S. Energy Information Administration (EIA) data, no number is typed in by an editor. This ranking is computed live from the EIA's most recent published generation-mix data. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error.
