100% Commitments in Cities, Counties, & States
Powered by 100% Renewable Energy: These communities have fully transitioned to 100% clean, renewable energy sources to power the community's electricity needs. 
Committed to 100% Renewable Energy: These communities have made community-wide commitments to transition to 100% clean, renewable energy no later than 2050. Across the U.S. over 90 cities, more than ten counties and two states, have already adopted ambitious 100% clean energy goals. Six cities in the U.S.--Aspen, Burlington, Georgetown, Greensburg, Rock port, and Kodiak Island--have already hit their targets. These six cities now generate 100% of the energy used community-wide from clean, non-polluting and renewable sources. A city commitment to 100% renewable energy is a mandate for action.
Numerous U.S. cities have made public commitments to cut carbon and address climate change through initiatives like the Compact of Mayors, We Are Still In, or by establishing their own Climate Action Plans.
Building on this history of climate leadership, we are calling on cities to transition to 100% clean, renewable energy.

What does it mean to be committed to, powered by, or working towards 100% clean, renewable energy?
Committed to 100% Renewable Energy: The Ready for 100 Campaign recognizes community commitments as places where a city’s leadership has established a goal to transition to the entire community to 100% clean, renewable energy. This can be through a stand-alone Resolution or Proclamation, or integrated into a community's Climate Action Plan or Energy Action Plan.
100% Commitment Guidelines
When crafting a commitment to 100% renewable energy, Ready For 100 recommends that the adopted goal includes the following elements:
- Community-wide Electricity Use: A full transition of the electricity sector to clean, renewable energy;
- By 2035: A target year for when this commitment will be achieved no later than 2035 for electricity and 2050 for all energy sectors;
- Ensure Justice, Equity, Affordability, and Access: A commitment should include measures that prioritize equity affordability, and access for all members of the community, prioritizing low income communities, environmental justice communities and communities burdened by the fossil fuel industry.
- Clean and Renewable Resources Only: This includes carbon and pollution free energy sustainably collected from renewable sources including wind, solar, tidal, and geothermal. Low-impact, small hydro and some forms of biomass may be included after being evaluated for sustainability and environmental justice implications. Nuclear, natural gas, coal, oil based, or any other forms of carbon-based energy production are not included as clean or renewable sources of energy. Sierra Club’s complete energy policy can be found here.
- A Transparent and Inclusive Planning and Implementation Process ensuring that the community members and local businesses have an opportunity to participate.
Strong commitments also include:
- All Energy Sectors: A commitment to transition other energy sectors to 100% including transportation and heating and cooling;
- A Local Generation Goal: A goal for how much of the community’s energy needs will be met by local, distributed generation;
- Near term implementation steps: At least the first year and ideally a five year plan;
- Commitment to Collaboration: A commitment to work with surrounding communities in achieving aligned clean energy and equity goals;
- Commitment to Advocate: A commitment to advocate for policies or regulations at the state, regional and/or federal level that aid the city in their transition
Powered by 100% Renewable Energy: A community is powered with 100% renewable energy when the amount of energy generated from renewable energy sources in the community (or brought into it) equals or exceeds 100% of the annual energy consumed within the community.
Working towards 100% Renewable Energy: A number of communities have pledged support for 100% clean energy, and some are demonstrating support for a transition to 100% clean energy by investing in renewable energy for municipal operations. To see a list of cities that have invested in renewable energy for their municipal operations check out EPA’s Green Power Communities.
