Earth Day is a good reminder that the most powerful environmental decisions aren’t made in boardrooms; they’re made in apartments. And in New York City, where buildings account for nearly 70% of all greenhouse gas emissions, what happens inside your unit genuinely matters. The good news is that saving energy in an NYC apartment doesn’t require a renovation budget or a landlord’s permission. A handful of smart, low-cost habits can cut your electricity bill and your carbon footprint at the same time. Here’s where to start.
Why NYC Apartments Are an Energy Savings Opportunity
New York City has some of the most ambitious climate legislation in the world. Local Law 97, enacted as part of the Climate Mobilization Act, requires most buildings over 25,000 square feet to meet strict greenhouse gas emissions limits, with the goal of reducing building emissions 40% by 2030 and reaching net zero by 2050. Buildings that exceed their carbon caps face fines of up to $268 per metric ton of CO₂ over the limit.
That pressure falls on building owners and boards, but residents play a bigger role than most people realize. Energy use inside individual units drives a significant share of a building’s total consumption, which means your daily habits directly affect how your building performs under the law.
The good news? Cutting your own energy use costs nothing for most of the changes below.
Hack #1: Hunt Down Your Energy Vampires
This is the most underrated, energy-saving move in any apartment, and it costs exactly zero dollars.
Energy vampires are electronics and appliances that continue drawing power even when you’re not actively using them. Televisions, computers, gaming systems, phone chargers, microwaves, coffee makers, and toaster ovens are the biggest culprits. They sit in standby mode, silently pulling electricity 24 hours a day.
The fix is simple: unplug devices when they’re not in use, or invest in a smart power strip that cuts power to idle electronics automatically. Smart plugs are another option they let you turn off power to specific outlets on a schedule or with a tap on your phone. For a New York City apartment where space is tight and devices are everywhere, this single habit can make a meaningful dent in your monthly Con Edison bill.
Hack #2: Switch Every Bulb to LED
If you still have incandescent or CFL bulbs anywhere in your apartment, replace them now. This is one of the fastest returns on a small investment available to any renter.
LED bulbs use up to 80% less energy than traditional incandescent bulbs and last up to 25 times longer. New York City already recognized this the city converted over 250,000 streetlights to LEDs, a move projected to save taxpayers about $14 million annually in energy and maintenance costs.
For a single apartment, the savings are proportionally significant. Bulbs are inexpensive, swapping them out takes minutes, and you can take them with you when you move. There’s no reason to delay this one.
Hack #3: Master Your Thermostat
Heating and cooling account for the largest share of energy use in any residential building. Getting smarter about your thermostat is one of the most impactful things an apartment resident can do.
The U.S. Department of Energy recommends setting your thermostat to 68°F in winter and keeping it as warm as is comfortable in summer especially when you’re not home. Lowering the temperature an additional seven to ten degrees while sleeping can meaningfully reduce energy use without any sacrifice in comfort.
If your apartment has its own thermostat and your landlord allows it, a programmable or smart thermostat takes the guesswork out of this entirely. It adjusts automatically based on your schedule, tracks your usage patterns, and can be controlled remotely when you forget to adjust settings before a weekend away. According to NYSERDA New York State’s energy research authority programmable thermostats are among the most effective tools renters have for reducing energy bills without making permanent changes to their space.
Hack #4: Seal Your Air Leaks (Without a Contractor)
Drafty windows and doors are one of the most common sources of energy waste in NYC apartments, especially in older buildings where weatherstripping has worn down over decades.
Weatherstripping is a renter-friendly, low-cost solution that closes off air gaps around doors and windows. When conditioned air escapes through these gaps, your heating and cooling system works harder to compensate, driving up energy use and your bill. Sealing those leaks reduces the load on HVAC systems, which benefits you directly.
Self-adhesive foam weatherstripping strips are available at any hardware store for a few dollars. You can install them yourself in under an hour and remove them when you leave, and your landlord will likely never notice. If your windows have a noticeable draft, a window insulator kit essentially a clear plastic film that adheres to the frame—offers an additional barrier during winter months.
Hack #5: Run Appliances Smarter, Not More
How you use your existing appliances matters almost as much as which appliances you own.
- Refrigerator: Keep the temperature between 35°F and 38°F. Remove dust from the coils behind and underneath at least once a year buildup forces the compressor to work harder. Minimize how often you open the door.
- Dishwasher and laundry: Always run full loads. During the summer, run them early in the morning or late at night
- Washing machine: Use cold water whenever possible. Modern detergents are designed to work in cold water, and the energy savings from skipping hot water are significant over time.
These aren’t sacrifices they’re habits. Built over a few weeks, they become automatic.
Hack #6: Use Fans Strategically
Running a window AC unit all summer is expensive. Fans cost a fraction of the energy according to some estimates, roughly 1% of the electricity of a central air conditioner and in New York’s milder spring and fall shoulder seasons, they’re often all you need.
One often-missed tip: if your fan has a reverse switch, flip it clockwise in winter. This pushes warm air that has risen to the ceiling back down into the room, reducing how hard your heating system has to work. It’s a two-second adjustment that delivers real savings.
Hack #7: Look Into NYC’s Free Energy Programs
NYC residents have access to programs that go far beyond individual habits, and these are worth knowing about.
NYSERDA’s EmPower+ provides income-eligible renters with no- and low-cost energy-efficiency solutions, including free upgrades to improve energy performance in their homes. Community Solar programs allow anyone who pays their own electric bill, including renters, to benefit from solar energy without installing panels. You subscribe to a share of a local solar project and receive a credit on your utility bill no rooftop required.
For buildings working toward Local Law 97 compliance, the NYC Accelerator offers free, personalized guidance to help building owners and managers reduce emissions and energy costs. Residents who bring these resources to the attention of their building boards are contributing to something bigger than their own bill.
Small Actions, Real Impact
Earth Day isn’t just a calendar reminder it’s a useful prompt to audit your habits and close the gap between what you know and what you actually do. In New York City, where the sheer density of residents means that small per-unit changes multiply across millions of apartments, individual action adds up faster than anywhere else in the country.
You don’t need to own your home, gut your kitchen, or spend thousands to make a difference. You need a smart power strip, a pack of LED bulbs, some weatherstripping, and a little attention to when and how you run your appliances.
Start this Earth Day. Your building and your electric bill will feel it.
