The New York City Housing Authority (NYCHA) released its new sustainability agenda on Thursday, and the leading initiative is solar power. The authority is pledging to generate 25 megawatts of power from solar panels by 2025. There will be 2.5 million square feet of panels. The Wall Street Journal says that’s enough to cover Washington Square Park. It would be enough to power 6,600 apartments. NYCHA has 178,000 units with 400,000 residents, making it the city’s biggest landlord.
