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 about $100 to $225 per year by switching all lighting to LEDs, depending on home size and how many bulbs are replaced.
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 | Budget whole-home switch |
Smart LEDs are worth considering if you want scheduling or dimming features. Automatically turning lights off when you leave can reduce lighting costs by another 10% to 20% in many homes. See the complete smart lighting guide on saltaecoliving.com for more on setting up a full smart lighting system.
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, depending on how you use it.
For most households, this works out to roughly $50 to $150 per year in savings.
For households that frequently leave the thermostat unchanged when no one is home, a smart thermostat can often recover its cost within a few years. Homes that already follow a strict setback schedule may see a much longer payback period.
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 smart features |
| 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 do not realize that electronics keep drawing power even when turned off. TVs, gaming consoles, cable boxes, and desktop computers can collectively add about $100 per year in standby power use in many homes. This is often called phantom load or vampire energy.
Smart power strips cut power to devices in standby mode, which reduces that waste. They are especially useful for home office and entertainment setups. Average annual savings are usually $20 to $75, depending on how many devices you have, with a payback period of about 6 months to 2 years.
What to Buy
| Power Strip | Price | Best Feature |
|---|---|---|
| Kasa Smart Wi-Fi Power Strip (EP40) | $35–$45 | Control individual outlets via app |
| APC Smart Plug Power Strip | $30–$40 | Adds surge protection |
| Belkin Conserve Smart Strip | $25–$35 | Cuts power when main device turns off |

4. Weatherstripping – Simple, Cheap, Surprisingly Effective
Air leaks around doors and windows force your heating and cooling system to work harder. Sealing air leaks can reduce heating and cooling costs by about 10% to 20% in many homes, depending on how drafty the home is.
Weatherstripping is one of the most cost-effective upgrades in this guide. Materials for a full home typically cost $30 to $100 and can be installed without any special tools.
Best Options by Gap Type
| Product | Price | Use It For |
|---|---|---|
| Foam tape | $5–$15 per roll | Window frames, small stationary gaps |
| Door sweep (adhesive) | $8–$20 | Bottom of exterior doors |
| V-seal weatherstrip | $10–$20 | Double-hung or sliding windows |
Start with exterior doors and doors leading to unheated spaces like garages. These are often the biggest sources of air leakage. You can feel drafts with your hand or use a candle near edges to spot leaks.
5. Home Energy Monitors – Know What Is Actually Costing You
Before spending money on efficiency upgrades, it helps to know where your energy is going. Home energy monitors connect to your electrical panel and track usage in real time, often down to individual circuits or devices.
I use the Emporia Vue and find the circuit-level monitoring genuinely useful for understanding where power is going.
Monitor Comparison
| Monitor | Price | Circuit Monitoring | Real-Time Updates | Notes |
|---|---|---|---|---|
| Emporia Vue | $169 | Yes | About every 1 second | DIY or pro install, solar compatible |
| Sense | $299 | No (device detection via AI) | About every 1 minute | Professional install recommended |
| Eyedro | $199 | Yes | About every 30 seconds | DIY or pro install |
The Emporia Vue’s $169 price point sits right at the edge of this guide’s range. It is worth it if you want detailed data. Many users find that identifying one or two energy-heavy devices can pay for the monitor quickly.
6. Smart Plugs – Set It and Forget It Savings
Smart plugs are inexpensive, easy to install, and useful. You plug one into your wall outlet, then plug your appliance into it. From there, you can control power through an app or voice commands.
They are especially useful for coffee makers, lamps, chargers, and small appliances that stay plugged in but are not always in use. In my own home, smart plugs turned out to be more useful for convenience than for major energy savings. The biggest benefit came from automatically shutting off lamps and chargers that otherwise stayed on around the clock.
Smart Plug Options
| Smart Plug | Price | Works With | Notes |
|---|---|---|---|
| TP-Link Kasa (EP25) | $10–$15 each | Alexa, Google, SmartThings | Tracks energy use |
| Wemo Mini | $15–$20 each | Alexa, Google, Apple HomeKit | Compact design |
| Amazon Smart Plug | $15–$20 each | Alexa only | Very easy setup |
Typical savings can range from $10 to $50 per year depending on what you control and how often devices are left on standby.
7. Energy-Efficient Window Coverings – Often Overlooked
Windows are one of the weakest points in a home’s insulation. Even efficient windows lose heat in winter and gain heat in summer. The right window treatments can help reduce that loss.
Cellular shades are usually the best all-around option because they trap air in pockets that act like insulation. Thermal curtains and solar screens also work well depending on your climate.
| Treatment | Price Range | Winter Heat Loss Reduction | Summer Heat Gain Reduction |
|---|---|---|---|
| Cellular shades | $30–$150/window | ~30%–40% | ~50%–60% |
| Thermal curtains | $25–$80/panel | ~20%–25% | ~25%–35% |
| Solar screens | $30–$100/window | ~10%–15% | ~60%–70% |
| Window film | $15–$50/window | ~20%–30% | ~40%–55% |
Cellular shades tend to offer the best overall performance. For south- and west-facing windows, solar screens or film often give the best return.
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 reduces both water and energy bills.
Modern low-flow fixtures maintain good pressure while using less water, so performance is much better than older versions.
Product Examples
| Product | Price | Flow Rate | Notes |
|---|---|---|---|
| High Sierra 1.5 GPM Showerhead | $25–$40 | 1.5 GPM | Strong pressure despite low flow |
| Niagara Earth Showerhead | $15–$25 | 1.25 GPM | Very low flow option |
| Moen Low-Flow Faucet Aerator | $10–$20 | 1.5 GPM | Easy sink retrofit |
A household of four switching from a 2.5 GPM showerhead to a 1.5 GPM model can save about $40 to $75 per year depending on water use and energy prices.
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.
