Many states have progressively increasing goals at different time frames; shown here are the endpoints (the most aggressive goals at the longest time frames). In several states the goals apply only to investor-owned utilities and not to cooperatives. The goals shown for New Mexico, New York and Washington specify “zero-carbon” or “zero-emission” technologies, which could include nuclear power. In some cases, the goals shown are voluntary rather than binding. For more details on each state’s policy, see the website “State Renewable Portfolio Standards and Goals,” compiled by the National Conference of State Legislators.

Never before have local actions been so critical. Governors, mayors, and town boards have initiated and expanded their commitments to climate action even as the U.S. federal government has stepped away from international climate leadership and rolled back more than 95 Obama-era climate policies, ambitions and regulations. There is a fascinating US interactive map, populated in real time, showing a geographical overview of financial incentives and regulatory policies, state-by-state, that promote renewable energy and energy efficiency here

States, Districts, and Territories are taking the initiative to switch over to renewable energy sources. 

Already, in 2015, Hawaii established a goal of 100% renewable electricity sources by 2045.

In 2018, under Governor Jerry Brown, California required that 50% of their electricity be powered by renewable resources by 2025 and 60% by 2030, while calling for a “bold path” toward 100% zero-carbon electricity by 2045.

By May 2019 (following Washington D.C. in January; New Mexico in March; Nevada and Puerto Rico in April) Washington became the 5th state to pass a 100% clean energy target. By the third week of June, New York’s Senate & Assembly passed the Climate Leadership and Community Protection Act. Signed by Governor Cuomo on July 18, 2019, it became the most comprehensive and aggressive climate change legislation in the nation.

Gov. Janet Mills announced at the UN in September, 2019 her executive order committing Maine to become carbon neutral by 2045; Colorado signed legislation which reduces 2030 greenhouse gas emissions by at least 50%; Nevada signed legislation to move to 50% renewable electricity by 2030 and 100% clean energy by 2050 and several more states — including New Jersey and Massachusetts adopted plans to achieve 100% clean energy by 2050, in addition to Washington — delivering legislation mandating 100% clean electricity by 2045 and Washington, D.C. committing to 100% clean, renewable electricity supply by 2032.

Most recently, March 6, 2020, Virginia’s Clean Economy Act passed, mandating the state’s utilities to deliver electricity from 100% renewable sources by 2045.

Cities, towns and municipalities are equally motivated: over 153 cities and thirteen counties have already adopted ambitious 100% clean energy goals. Six additional U.S. cities — Aspen CO, Burlington VT, Georgetown TX, Greensburg KS, Rock Port MO, and Kodiak Island AK — have already hit their targets, generating 100% of their energy from clean, non-polluting and renewable sources…
