| 13 | New Mexico | 100% carbon-free electricity by 2045 | 2019 legislation (SB 489) requires utilities to have a zero-carbon power supply by 2045, including at least 80% from renewables, with the exception of rural electric coops which have a 2050 target date. |
| 14 | New York | 100% carbon-free electricity by 2040 | 2019 legislation (S6599) requires zero-emissions electricity by 2040 and sets a goal of cutting all state GHGs 85% by 2050. A Climate Action Council will develop a plan. |
| 15 | Puerto Rico | 100% renewable energy for electricity by 2050 | 2019 legislation (SB1121), the Public Energy Policy Law of Puerto Rico, set a timeline for reaching 100% renewable electricity by the year 2050. |
| 16 | Rhode Island | 100% renewable energy electricity by 2033 | Governor Gina Raimondo’s 2020 Executive Order (20-01) requires the Office of Energy Resources to “conduct economic and energy market analysis and develop viable policy and programmatic pathways” to meet 100% of statewide electricity deliveries with renewables by 2030. 2022 legislation (H7277 SUB A) updates the state's RPS to require 100% of RI's electricity to be offset by renewable production by 2033. |
