A calmer approach to summer energy use in NYC

A New York heatwave changes the rhythm of home. Window shades stay down through the afternoon, one room becomes the cool room, and an air conditioner that was barely noticeable in June suddenly becomes part of the daily budget.
For renters, owners, and small-building residents alike, reducing summer electricity use is not about sacrificing comfort. It is about paying attention to how a home holds heat, when we use the most power, and which small improvements can make city living feel more manageable.
Start with the apartment you already have
In many older New York buildings, cooled air finds its way out through the same small gaps that let winter drafts in. Check around windows, exterior doors, and window AC units. A properly fitted unit, weatherstripping, or a simple door sweep can help keep conditioned air where it belongs.
Windows deserve attention, too. Closing blinds or curtains during the sunniest part of the day reduces heat gain before the AC has to work against it. Blackout shades can be especially useful in rooms that receive direct afternoon light. These are modest changes, but they support both comfort and lower energy use.
Think about timing, not just total use
On the hottest days, electricity demand is generally greatest from the afternoon into the evening. Whenever schedules allow, run the dishwasher, laundry, or other energy-intensive appliances outside those hours. If you use more than one air conditioner, consider whether one well-positioned unit and a fan can carry the apartment during peak periods.
Fans use far less electricity than AC and can make a room feel noticeably cooler by moving air across the skin. They do not replace cooling when conditions are unsafe, but they are a practical partner to it. The goal is not perfection; it is to avoid using more energy than the moment requires.
Give the AC a little care
A clogged filter or dusty coil asks an air conditioner to work harder. Before the hottest stretch of summer, clean or replace the filter according to the manufacturer’s instructions and make sure the unit is securely installed. If replacement is on the horizon, look for an Energy Star model sized appropriately for the room. Bigger is not always better: an oversized unit can cool a room too quickly without managing humidity well.
Lighting is another easy place to begin. LEDs use substantially less energy than older incandescent bulbs and last longer, making them a sensible upgrade for lamps and fixtures used every day.
Look beyond the individual apartment
There are also citywide and building-level ways to participate. Eligible Con Edison customers may be able to earn rewards for reducing electricity use during high-demand events. GridRewards, from Logical Buildings, is one program that helps eligible residents participate in demand-response events and earn rewards for reducing electricity use when the grid is under the most strain.
For households using window or portable A/C units, Every Electric offers a battery-assisted A/C program designed to shift some cooling demand away from peak periods without requiring a permanent installation. Program availability, A/C compatibility, rewards, deposits, and terms should be confirmed directly with the provider before enrolling.
Community solar can offer bill credits without requiring residents to install panels on their own roofs. Availability and eligibility vary, so it is worth reading the terms carefully before enrolling.
For co-ops and condos, conversations about energy use can be part of responsible building stewardship. Common-area lighting, ventilation, amenity schedules, and resident education all influence a building’s overall demand. The most effective approach is usually collaborative: clear information, realistic goals, and respect for the fact that everyone experiences heat differently.
Summer in New York asks a lot of our homes. A few thoughtful adjustments can help them respond with less waste, more comfort, and a little more resilience for the blocks we share.
