For anyone paying attention, the ambitious 2019 Climate Leadership and Community Protection Act (CLCPA) raised serious questions about how New York intends to achieve near-net zero greenhouse emissions by 2050. Electrification of cars and building heating systems will be key. But that begs the question of how the state will meet the demand for electricity. Electric cars and electric heaters are only as carbon-free as the generating sources powering them. In 2019 only about a quarter of the electricity generated in New York came from renewable sources, primarily hydropower. To achieve CLCPA's ambitious goals, New York must dramatically expand renewable energy production and intra-state transmission of that energy.
