Energy Saving Guide for Renters and Apartments

Most energy-saving advice assumes you own the property — add attic insulation, replace the windows, upgrade to a heat pump. None of that applies if you’re renting, and a lot of renter-focused content just skips straight to “turn off lights” without addressing the real, substantial savings available in a rental if you know which of our other guides’ advice actually translates. This guide pulls together what genuinely works for renters and apartment residents — fully reversible, lease-safe, and effective without a single permanent change to the property.

Why Rental Energy Use Often Runs Higher Than It Should

A few structural realities make rentals prone to waste that has nothing to do with the tenant’s habits:

Landlords often choose the cheapest appliances, not the most efficient ones, since they’re not the ones paying the ongoing utility bill.
Weatherization is frequently neglected in rental units, since the cost of sealing drafts or adding insulation falls on an owner who may not see a direct financial return the way an occupant-owner would.
You can’t control major systems — the furnace, central AC, or water heater’s efficiency and age are simply inherited from whatever the landlord has installed, with no ability to upgrade them yourself.

Knowing this upfront reframes the goal: as a renter, your realistic ceiling for savings comes from behavior, portable/removable products, and smart advocacy — not structural upgrades.

Fully Reversible Weatherproofing

As covered in our comprehensive guide on [how to weatherproof doors and windows], several of the highest-impact sealing techniques are entirely renter-safe:

Removable window insulation film — applied with double-sided tape, easily removed in spring with no residue or damage, directly addressing one of the biggest sources of seasonal heat loss/gain through older or poorly-sealed windows.
Draft stoppers for door bottoms — simple, non-adhesive devices that sit against the base of a door, fully removable and reusable from one apartment to the next.
Removable weatherstripping — adhesive-backed foam strips are inexpensive and, while technically a minor adhesive application, are generally considered acceptable and easily removed without damage; check your specific lease terms if you’re unsure.
Heavy or thermal curtains — a fully portable, no-installation way to add insulating value over windows, closed during the coldest or hottest parts of the day.

Appliance and Habit-Based Savings That Transfer Anywhere

Nearly everything covered in our guide on [20 real ways to lower your electric bill] applies regardless of ownership status, since these are behavioral or portable-product changes rather than structural ones. The highest-impact, renter-relevant subset:

Cold water laundry washing, which (as covered in our [washing machine electricity usage] breakdown) addresses the single biggest cost driver for that specific appliance regardless of who owns the machine.
LED bulb replacement — simply unscrew the landlord’s incandescent or older bulbs, store them safely, and screw LEDs in during your tenancy; swap back (or leave the LEDs, which is common courtesy but not required) when you move out. See our [LED bulb savings] breakdown for the fast payback math.
Smart plugs for phantom load devices — fully portable, require no wiring changes, and move with you between apartments. See our [best smart plugs for monitoring energy usage] and [what is phantom load] guides for specifics.
A portable energy monitor (a plug-in Kill-A-Watt meter or a smart plug with monitoring) to identify which of your own devices are the biggest draws, independent of anything structural about the unit itself.

Thermostat Control: What You Likely Already Have

Most rentals include at least a basic thermostat, and the core savings habits from our guide on [20 real ways to lower your electric bill] apply regardless of whether it’s a smart model or a simple dial:

A consistent, modest setback while sleeping or away, even on a basic non-programmable thermostat, delivers real savings without requiring any new hardware at all.
If your lease allows minor fixture swaps, a battery-powered or plug-in portable programmable thermostat can sometimes be installed without modifying the unit’s wiring — check with your landlord first, and keep the original thermostat to reinstall before moving out if you do replace it temporarily.

Smart Devices That Need No Installation

Smart plugs, covered above, require no wiring and no landlord permission in the overwhelming majority of cases, since they simply plug into an existing outlet.
Battery-powered smart sensors (motion, contact) that use adhesive mounts rather than screws are a reasonable way to add some automation without any permanent fixture changes.
Portable smart speakers or displays for voice-controlled routines don’t require any installation at all.

Advocating for Efficiency Improvements (Worth Trying)

Some efficiency upgrades genuinely require landlord action, but it’s worth asking rather than assuming the answer is no:

Request LED bulbs in common/exterior fixtures the landlord controls, framing it as a request that benefits them too if they pay for common-area electricity.
Ask about weatherstripping or caulking around obviously drafty windows and doors — a landlord sometimes prefers a cheap sealing fix over not knowing about (and eventually having to address) a larger moisture or draft problem.
Ask whether the unit qualifies for any utility or state efficiency rebate programs that cover rental properties — some jurisdictions specifically fund landlord-side efficiency upgrades (insulation, appliance replacement) at reduced or no cost to the owner, which removes the landlord’s main objection (cost) to making a change.
If you pay utilities directly and usage data shows an inefficient major appliance (an old refrigerator left by a previous tenant, for example), sharing that specific data with your landlord sometimes prompts a cost-benefit conversation that a vague complaint wouldn’t.

What to Check Before You Even Move In (If You Have the Choice)

If you’re apartment-hunting and have some choice in the matter, a few questions during a showing can save real money over a lease term:

Ask about the age of major appliances — an older refrigerator or window AC unit can meaningfully affect your bill regardless of your own habits, as covered in our [which appliances use the most electricity] ranking.
Ask whether utilities are individually metered or included in rent/split among units — individually metered units give you direct control over your own savings; shared or flat-rate utility arrangements remove most of your ability to benefit from your own conservation efforts.
Check window age and visible condition during the showing, since older single-pane windows are a reliable predictor of higher heating/cooling costs regardless of your sealing efforts.
Ask what heating/cooling system is in place — a unit with an old electric resistance baseboard system (see our [heat pump vs. electric baseboard heating] comparison) will reliably cost more to run than one with a modern heat pump or efficient central system, independent of anything you do.

A Renter’s Priority Checklist

Start with the fully free habit changes — cold water laundry, thermostat setbacks, closing curtains strategically.
Add portable, renter-safe products — LED bulbs, smart plugs, window film, draft stoppers.
Use a portable energy monitor to identify your own specific biggest opportunities, since generic advice can’t account for your unit’s specific appliances and layout.
Advocate for landlord-side fixes where relevant, particularly if utility rebate programs could offset the landlord’s cost.
Factor energy efficiency into your next apartment search, if you have any flexibility in your choice, since some structural factors (appliance age, window quality, heating system type) are simply outside a tenant’s control once you’ve signed a lease.

Final Thoughts

Renting doesn’t mean giving up on meaningfully lowering an electric bill — it means focusing specifically on the behavioral changes, portable products, and reversible fixes that don’t depend on owning the property, while being strategic about which structural improvements are worth asking a landlord for. Nearly every habit-based and smart-device strategy covered elsewhere on this site applies just as well in a rental as in an owned home; the main difference is simply ruling out the insulation, window replacement, and major system upgrades that require ownership, and doubling down on what’s actually available to you instead.
