Becoming more energy efficient at home is not just about cutting back or “doing without.” It is about getting the same, or better, comfort and performance from your home while using less energy and spending less money.
This guide walks through the most impactful energy-efficient products for your home, how they work, what to look for when you shop, and how to pair them with the right electricity plan (if you live in a deregulated area) using Power Wizard.
An energy-efficient product delivers the same function or comfort using less energy than a standard option. You still get cold air, hot water, clean clothes, bright lighting, and more, but your home uses fewer kilowatt-hours (kWh) to achieve those results. For example:
Below are the highest-impact products you can adopt in your home, along with how they work, what to look for, and where they save the most.
What they do
Smart thermostats connect to your Wi-Fi and automatically adjust heating and cooling settings based on your preferences, schedule, and often your location. It can learn when you are home, when you typically leave, and which temperatures you prefer.

What they do
LED (light-emitting diode) bulbs and fixtures produce the same amount of light as traditional bulbs while using far less energy and lasting up to 25 times longer than incandescent bulbs.

What they do
Advanced power strips (APS) and smart plugs reduce the electricity used by phantom loads (also called vampire load or standby power), which is the power drawn by devices even when they appear to be off but remain plugged in.

What they do
High-efficiency (HE) washers are designed to clean clothes using significantly less water and energy than traditional washers. You can extend these savings by washing only full loads with cold water.

Beyond washers, several other major appliances offer strong energy savings when you choose ENERGY STAR® certified models:
ENERGY STAR® certified products are independently tested and must meet or exceed energy-efficiency standards set by the U.S. Environmental Protection Agency and the Department of Energy.
| Product Category | Typical Savings Potential* | Upfront Cost Range | Installation Difficulty | Best Use Cases |
|---|---|---|---|---|
| Smart Thermostat | Significant HVAC savings in most homes | $$ | Moderate | Homes with central HVAC and regular schedules |
| LED Bulbs and Fixtures | Up to 90% less energy for lighting vs. incandescent | $ | Easy | Whole-home lighting upgrades |
| Advanced Power Strips / Plugs | Can trim “vampire” loads by up to ~$200/year | $ | Easy | Entertainment centers, home offices |
| High-Efficiency Washer | Less hot water and electricity for laundry | $$–$$$ | Moderate | Medium-to-large households |
| ENERGY STAR® Major Appliances | Ongoing reduced operating costs | $$–$$$ | Moderate–Advanced | When replacing older appliances or HVAC units |
It can be difficult to gauge efficiency just by looking at an appliance. That is why standardized labels exist to help you make informed choices.

How to use it
Improving efficiency at home might seem like a small step, but the impact on your wallet and the environment can be significant.
Beyond individual homes, energy efficiency also influences how buildings and infrastructure are designed:
The bottom line: When many people adopt energy-efficient products and habits at home, the collective effect lowers emissions, eases stress on the grid, and helps avoid costly new power plants or large-scale infrastructure projects. It also encourages investment in and development of more sustainable energy infrastructure.
Improving your home’s energy efficiency doesn’t have to happen all at once. You can phase changes to get quick wins while planning for larger upgrades over time.
Start with easy, affordable improvements that deliver immediate savings:
These steps usually require little to no professional help, are relatively inexpensive, and pay back quickly.
Next, evaluate bigger-ticket items that can deliver long-term value:
If you’re in a deregulated area, confirm that your electricity rate is competitive for your usage pattern. Paying too much per kilowatt-hour can offset the savings you gain from efficient products.
Power Wizard shows you available energy plans in your area, so you can select a plan that aligns with your home and average consumption, rather than overpaying for electricity.
The best renter-friendly upgrades are non-permanent and portable, such as LED bulbs for high-use fixtures, smart plugs, and advanced power strips for TVs, gaming systems, and chargers, plus draft stoppers, removable weatherstripping, and thermal curtains for comfort. Where leases allow, renters may also use smart thermostats and low-flow showerheads. Always review the lease, get written permission for any thermostat or fixture changes, and keep original parts to reinstall at move-out.
Start with a simple three-tier approach:
Begin with Tier 1, use those savings to fund Tier 2, and plan Tier 3 replacements around major repairs or remodels to maximize long-term value.
Check three things: age, labels, and performance. Appliances that are 10–15+ years old, lack an ENERGY STAR® label, or have no current EnergyGuide label are strong candidates for replacement. Look for signs like struggling to maintain temperature, unusually long cycles, constant running, frequent repairs, or excessive noise. As a rule of thumb, replacement usually makes sense when an older, high-use appliance is near or past its typical lifespan and repair costs are approaching 50% of the price of a new, efficient model.
Energy conservation means changing behavior to use less energy, like turning off lights when leaving a room or lowering the thermostat and wearing a sweater. Energy efficiency means using technology that delivers the same or better result with less energy, such as replacing incandescent bulbs with LEDs or upgrading to an ENERGY STAR® refrigerator. Conservation focuses on habits, while efficiency focuses on equipment; the biggest savings come from combining both.
