1. LED Light Bulbs – The Easiest Win
If you still have any incandescent bulbs in your home, replacing them with LEDs is the single fastest way to cut your electricity bill. According to the Department of Energy, LEDs use at least 75% less energy than incandescent bulbs and last up to 25 times longer. The average household can save around $100 to $225 per year by making a full switch, with bigger homes seeing more.
Standard LED bulbs now cost as little as $1–$3 each for basic white bulbs and $8–$20 for smart bulbs with app or voice control. The math is straightforward: a 60W-equivalent LED costs roughly $1.70 per year to run at five hours daily, compared to about $17 for the incandescent bulb it replaces.
Smart LEDs add scheduling and dimming, which is useful for reducing waste when you forget to turn lights off. Moreover, smart lighting products can be programmed to perform actions automatically based on your schedule or occupancy detection, which reduces how long lights run unnecessarily. Just keep in mind that the main savings come from the LED itself, not the smart features. So if budget is tight, basic LEDs are the better starting point.
What to Buy
| Bulb | Price Range | Best For |
| GE Relax LED (4-pack) | $10–$14 | General use, warm white light |
| Kasa Smart LED (KL110, 4-pack) | $22–$28 | App/voice control, scheduling |
| Philips Hue White (4-pack) | $45–$55 | Full smart home integration |
| Amazon Basics LED (16-pack) | $16–$22 | Whole-home budget switch |

2. Smart Thermostats – High Impact, Worth Every Dollar
Your heating and cooling system is responsible for roughly half your home’s energy bill. A smart thermostat will not fix an aging furnace or a poorly insulated attic, but it can stop you from heating or cooling an empty house. The EPA estimates 10–15% savings on heating and cooling costs, which works out to about $50 to $150 per year for most households.
Households that currently leave the thermostat unchanged when no one is home tend to see the biggest gains. If you already follow a strict setback schedule manually, the payback period will be longer, possibly several years rather than one or two.
Top Picks for 2026
| Thermostat | Price | Best For | Key Feature |
|---|---|---|---|
| Amazon Smart Thermostat | ~$80 | Alexa households, tight budget | Fastest payback (often under 1 year in high-use homes) |
| Honeywell Home T9 | ~$149 | Multi-room homes | Room sensors detect occupancy |
| Ecobee Smart Thermostat Premium | ~$200–$250 | Complex HVAC systems | Strong sensor support and broad HVAC compatibility |
| Google Nest Learning Thermostat (4th Gen) | ~$279 | Hands-off households | Self-programs over time |
The Nest and Ecobee come in above the $200 threshold for this guide, but utility rebates in many states often bring effective costs down to $90 to $150. Always check your utility’s rebate portal before buying.
If you already adjust your thermostat manually, savings will likely be smaller. The biggest gains go to households that currently heat or cool the house when no one is home.
3. Smart Power Strips – Eliminate the Hidden Drain
Most people don’t realize that electronics keep drawing power even when turned off. TVs, gaming consoles, cable boxes, and other devices can add tens of dollars per year in standby power use. In homes with many always-on devices, the total can climb higher. The Department of Energy estimates that standby power accounts for about 10% of a typical home’s electricity use, what’s often called phantom load or vampire energy.
Smart power strips cut power to devices in standby mode automatically, which reduces that waste. They’re most useful in home office and entertainment setups where multiple devices stay plugged in around the clock. Annual savings typically run $20 to $75, with a payback period anywhere from six months to two years.
The Kasa Smart Wi-Fi Power Strip (EP40, around $35–$45) lets you control individual outlets through an app and works with Alexa and Google. The APC Smart Plug Power Strip (around $30–$40) adds surge protection alongside smart controls, which is worth having for more expensive electronics. The Belkin Conserve Smart Strip (around $25–$35) takes a simpler approach: it cuts power to accessories automatically when the main device, for example, your computer or TV, turns off or goes idle.
For a deeper look at how these work, see: Everything You Need to Know About Smart Power Strips.
4. Weatherstripping – Simple, Cheap, Surprisingly Effective
Air leaks around doors and windows force your HVAC system to work harder to maintain temperature. The Environmental Protection Agency estimates that sealing air leaks can reduce heating and cooling costs by 15% in many homes. The exact impact depends on how drafty the home is to begin with. For example, older homes with poorly fitted doors or single-pane windows tend to see the most improvement.
Materials for a full home typically cost $30 to $100 and can be installed without special tools. Start with exterior doors and any door leading to an unheated space like a garage. These are usually the biggest sources of air leakage. You can feel drafts by running your hand along door edges or use a candle to spot leaks.
Foam tape (about $5–$15 per roll) is the easiest option and works well for stationary gaps like window frames. Door sweeps ($8–$20) attach to the bottom of exterior doors and block drafts effectively. V-seal weatherstrip ($10–$20) is better for double-hung or sliding windows because it compresses when the window closes, creating a tighter seal.
5. Home Energy Monitors – Know What Is Actually Costing You
Before spending money on efficiency upgrades, it helps to know where your energy is actually going. Home energy monitors connect to your electrical panel and track usage in real time, often down to individual circuits. This lets you see which appliances or habits are quietly driving up your bill.
I use the Emporia Vue ($169) and find the circuit-level detail genuinely useful. Many users find that identifying one or two energy-heavy devices pays for the monitor within a few months. The Sense ($299) takes a different approach — it uses AI to detect individual devices by their electrical signatures rather than monitoring circuits directly, which requires professional installation but gives you device-level data without wiring each circuit separately. The Eyedro ($199) splits the difference, offering circuit-level monitoring with a 30-second update interval.
The Emporia Vue sits right at the edge of this guide’s $200 threshold. If you want to understand your home’s energy use before committing to bigger upgrades, it’s worth the investment.
6. Smart Plugs – Set It and Forget It Savings
Smart plugs are inexpensive and easy to use. You plug one into your wall outlet, then plug your appliance into it, and you can control power through an app or voice command. No wiring, no installation.
They work best for devices that stay plugged in around the clock but aren’t always in use: coffee makers, lamps, phone chargers, and small appliances. In my own home, smart plugs turned out to be more valuable for convenience than for dramatic energy savings. The biggest benefit came from automatically shutting off lamps and chargers that otherwise ran continuously.
The TP-Link Kasa EP25 ($10–$15) tracks energy use per outlet and works with Alexa, Google, and SmartThings. The Wemo Mini ($15–$20) is compact enough to fit in tight spaces without blocking the adjacent outlet, and supports Apple HomeKit in addition to Alexa and Google. The Amazon Smart Plug ($15–$20) is the simplest option if you’re already in the Alexa ecosystem — setup takes a few minutes.
Typical savings range from about $10 to $50 per year, depending on what you’re controlling and how often those devices would otherwise stay on standby. For apartment-specific recommendations, see: Best Smart Home Devices for Apartments.
7. Energy-Efficient Window Coverings – Often Overlooked
Windows are one of the weakest points in a home’s thermal envelope. Even well-made windows lose more heat per square foot than an insulated wall. The right window treatments reduce that loss without requiring any structural changes.
In cold climates, cellular shades usually deliver the most energy benefit. They work by trapping air in small honeycomb-shaped pockets, which act like insulation against the glass. Estimates for heat loss reduction vary, but they generally outperform other window treatments in heating-dominated climates. For south- and west-facing windows where summer heat gain is the main concern, solar screens are often a better choice — they block a significant share of incoming solar radiation before it enters the room. Window film is a lower-cost option that reduces both heat gain and loss, and is easy to apply to existing windows without replacing hardware.
Thermal curtains are widely available and inexpensive ($25–$80 per panel), and they do provide some insulation benefit, though less than cellular shades. They’re a reasonable starting point for renters or anyone who doesn’t want a permanent window treatment. Price ranges for cellular shades run roughly $30–$150 per window, solar screens $30–$100, and window film $15–$50, all well within the budget of this guide.
8. Low-Flow Showerheads and Faucets – Water and Energy Together
Water heating accounts for about 18% of the average home’s energy use, according to the Department of Energy. Using less hot water means your water heater runs less, which reduces both your water and energy bills at the same time. The most common starting flow rate in older homes is 2.5 gallons per minute. Switching to a 1.5 GPM showerhead cuts hot water use by 40% without requiring any changes to your plumbing.
The High Sierra 1.5 GPM Showerhead ($25–$40) is one of the more popular options because it maintains noticeably good pressure for a low-flow fixture. The Niagara Earth ($15–$25) goes even further at 1.25 GPM, which is toward the low end of what most people will tolerate without complaining. For kitchen and bathroom sinks, a low-flow faucet aerator like the Moen option ($10–$20) is a retrofit that screws onto your existing faucet and reduces flow to 1.5 GPM. These are among the lowest-cost, fastest-payback upgrades in this guide.
What About Bigger Upgrades?
A few high-impact products fall outside the $200 budget in this guide but are worth knowing about if you’re planning future investments:
- Heat pump water heaters: These use about 70% less energy than standard electric water heaters and can save a family of four up to $550 per year, according to ENERGY STAR. Units typically cost $800–$1,500 before rebates. The federal 25C tax credit expired at the end of 2025, but many utility rebates of $400–$750 are still available depending on location. See: Top Solar Water Heaters and Heat Pump Options.
- Home battery backup: If you have solar or want grid support during outages, home battery systems store energy for later use. They can also help shift electricity use to cheaper off-peak hours in some utility rate plans. See: Best Home Batteries of 2026.
- Home energy audit: Before making larger investments, it helps to know where your home loses energy most. A professional audit typically costs $200–$600, and many utility companies offer free or discounted versions. See: What Is a Home Energy Audit and Why Is It Important?.

Frequently Asked Questions
What home improvements increase energy efficiency the most?
Air sealing and insulation usually have the biggest impact because they reduce heat loss and gain at the source. Among products you can install yourself, LED lighting and smart thermostats tend to offer the best savings for the cost. For a deeper dive, see: Conquer Rising Energy Costs: A Practical Guide to Energy Efficiency at Home.
What is the most energy-efficient home appliance?
This depends on the category, but heat pump technology is the most efficient option across several major appliances. Heat pump water heaters use about 60% to 70% less electricity than standard electric models. Heat pump dryers use about 20% to 50% less energy than conventional electric dryers. For whole-home heating and cooling, cold-climate heat pumps are often more efficient and lower cost to operate than gas furnaces in many regions.
Is it worth upgrading to a smart home for energy savings?
Partially. Individual smart devices like thermostats, plugs, and lighting provide real and measurable savings. Full smart home integration can add convenience and some additional efficiency, but the upfront cost is higher and the added savings beyond individual devices are usually modest. A good approach is to start with individual devices and expand only if they prove useful in your home. See: Smart Home Energy Technology.
Are these energy-saving products worth it for apartments?
Most of them are, yes. LED bulbs, smart plugs, low-flow showerheads, and smart power strips all work in apartments and do not require installation. Smart thermostats depend on whether you control your own HVAC system, which is often not the case in rental units. Check: Best Smart Home Devices for Apartments.
Do I need a smart home hub to use these products?
No. Most products in this guide work on their own using their own apps. Some also connect to platforms like Amazon Alexa, Google Home, or Apple HomeKit, but that is optional and not required for energy savings.
