How to Save on Your Electricity Bill

The two paths to lower bills

Every strategy for reducing your electricity bill falls into one of two categories: paying less per unit of electricity, or using fewer units. That's it. All the advice, tips, and hacks reduce to these two levers.

Path 1: Shop for a better rate.If you're in a deregulated market and paying more than the best available supplier rate, switching delivers immediate savings with zero behavior change. This is the bigger lever for most households.

Path 2: Reduce your usage. Using less electricity saves money regardless of your rate. The savings compound over time but require either behavior change (turning things off) or upfront investment (better equipment).

Most people should do both, but if you can only focus on one, start with the rate. It's faster, requires less effort, and often delivers larger absolute savings.

Shop suppliers — the bigger lever

In deregulated electricity markets (including Pennsylvania, Texas, Ohio, parts of New York, and others), you can choose who supplies your power. Suppliers compete on price, and the spread between the most and least expensive options can be significant.

The math behind supplier savings

Your savings from switching suppliers equals:

(Current rate - New rate) × Monthly usage = Monthly savings

For a household using 1,000 kWh per month:

• A 1¢/kWh rate reduction saves $10/month ($120/year)
• A 2¢/kWh rate reduction saves $20/month ($240/year)
• A 3¢/kWh rate reduction saves $30/month ($360/year)

The typical spread between utility default rates and the best competitive supplier rates varies by market. In Pennsylvania, spreads of 1-3¢/kWh are common. In Texas, spreads can be larger. The point: if you haven't shopped, you're likely leaving money on the table.

Why this is the bigger lever

Switching suppliers takes minutes and requires no ongoing effort. You compare rates, choose a plan, enroll online, and you're done. Your savings arrive automatically on every bill.

Contrast that with reducing usage: turning off lights requires constant vigilance; upgrading to efficient appliances requires upfront spending; adjusting your thermostat means comfort trade-offs. These all work, but they require ongoing discipline.

For most households who haven't recently shopped for a supplier, switching delivers more savings with less effort than any other single action.

Reduce usage — the smaller but compounding lever

Using less electricity saves money at any rate. And unlike rate shopping (which requires periodic re-shopping as contracts expire), efficiency improvements and behavior changes deliver savings indefinitely.

Where your electricity actually goes

Before cutting usage, understand where it goes. According to the U.S. Energy Information Administration, the average American household's electricity breaks down roughly as:

• Heating and cooling: 50%+ (varies dramatically by climate and home)
• Water heating: 10-15%
• Lighting: 5-10%
• Refrigeration: 5-8%
• Other appliances and electronics: 15-25%

The implication is clear: focus on heating/cooling first. Everything else is rounding error by comparison.

Quick wins (low effort, moderate savings)

• Adjust your thermostat. Each degree of setback saves roughly 1-3% on heating/cooling costs. Setting your thermostat to 68°F in winter (rather than 72°F) or 76°F in summer (rather than 72°F) makes a noticeable difference.
• Use a programmable or smart thermostat.Automated setbacks when you're asleep or away add up. A smart thermostat pays for itself within a year for most households.
• Switch to LED bulbs. LEDs use 75% less electricity than incandescents. If you still have old bulbs, replacing them is one of the highest-ROI improvements.
• Seal obvious air leaks. Weatherstripping doors and caulking windows costs little and reduces heating/cooling load. Focus on drafty areas first.
• Use ceiling fans strategically. Fans make rooms feel cooler without actually lowering the temperature. Running a fan lets you raise the AC setpoint by 4°F or more while maintaining comfort.

Long-term strategies (higher effort or investment, larger savings)

• Upgrade old appliances. A 15-year-old refrigerator uses significantly more electricity than a new ENERGY STAR model. When appliances fail, replace them with efficient models. Proactive replacement makes sense for the worst offenders.
• Improve insulation.Adding attic insulation reduces heating/cooling needs significantly in many homes. It's not cheap, but it pays back over years.
• Consider window upgrades. Old single-pane windows are major sources of heat loss/gain. Replacement is expensive but delivers both energy savings and comfort improvements.
• Right-size HVAC equipment. When your AC or furnace needs replacement, get it properly sized. Oversized equipment cycles inefficiently; undersized equipment runs constantly. A proper load calculation matters.
• Install solar panels.Solar doesn't reduce usage, but it offsets what you buy from the grid. Economics depend heavily on your location, utility rates, available incentives, and roof orientation.

Bill components explained

Understanding your bill helps you know where savings are actually possible. A typical residential electricity bill includes four categories of charges:

Generation (supply)

This is the cost of producing the electricity you use. It's calculated as your usage in kWh times your generation rate. In deregulated markets, this is the portion you can shop for.

Transmission

Transmission charges cover moving high-voltage electricity across long distances from power plants to your local utility's distribution system. You don't choose your transmission provider; these charges are regulated.

Distribution (delivery)

Distribution charges cover your local utility's costs: maintaining poles and wires, reading meters, handling outages, billing. You can't shop for distribution — your utility is your utility.

Taxes, fees, and surcharges

Various state and local taxes, universal service fund contributions, and other regulatory fees appear as line items. These are what they are; you can't shop them away.

The key insight:In deregulated markets, you can only shop for generation. Everything else is fixed. If generation is 40% of your bill and you cut your generation rate by 20%, your total bill drops by 8%. That's still meaningful, but it's not 20%.

Common myths debunked

“Unplugging phone chargers saves significant money”

Modern phone chargers draw negligible power when not actively charging — typically less than 0.5 watts. At 10¢/kWh, that's less than $0.50 per year per charger. Unplugging every charger in your house might save $2-3 annually. Not worth the hassle.

The “phantom load” concern made more sense with older electronics. Some devices (cable boxes, gaming consoles in standby) do draw meaningful standby power. But most modern small devices are efficient enough that obsessive unplugging doesn't move the needle.

“Running appliances at night is always cheaper”

Only if you're on a time-of-use rate plan that charges less during off-peak hours. Most residential customers are on flat-rate plans where electricity costs the same at 2 AM as at 2 PM. Check your rate structure before shifting your laundry schedule.

“Electric space heaters are efficient”

Electric resistance heaters convert nearly 100% of electricity to heat, which sounds efficient. But electricity is an expensive way to generate heat compared to natural gas or heat pumps. Running a space heater can easily cost $50-100+ per month. They're fine for spot heating a small space briefly, but expensive for whole-house heating.

“Closing vents in unused rooms saves energy”

Counterintuitively, closing vents often increases energy use. Forced-air HVAC systems are designed for certain airflow. Closing vents increases pressure, reduces efficiency, and can damage equipment. Better to leave vents open and adjust setpoints.

Quick-win action items

If you want to lower your electricity bill today, do these in order:

1. Check if you're in a deregulated market. If so, you can shop for suppliers.
2. Find your current generation rate.Look on your bill for the “Price to Compare” (PA) or equivalent.
3. Compare available rates.Use your state's official comparison tool or a site like this one.
4. Switch if the math works. If you can save 1¢/kWh or more, switch. It takes 10 minutes.
5. Program your thermostat.Set it back when you're asleep or away.
6. Replace incandescent bulbs with LEDs. Start with the lights you use most.
7. Schedule an annual rate review. Set a calendar reminder to check rates before your contract expires.

Frequently asked questions

What's the fastest way to lower my electricity bill?

If you're in a deregulated market and haven't shopped for a supplier, switching to a competitive rate is the fastest path. It takes minutes to compare, requires no behavior change, and can save $100-300 per year or more depending on your usage and current rate.

How much can I really save by switching electricity suppliers?

Savings depend on the gap between your current rate and competitive rates. A 2¢/kWh difference on 1,000 kWh/month usage saves $20/month or $240/year. In markets with larger spreads, savings can exceed $300/year. In tighter markets, savings may be smaller.

Does unplugging devices really save money?

Unplugging phone chargers and small devices saves very little — typically a few dollars per year. The bigger opportunities are reducing heating and cooling costs (50%+ of most bills), switching to LED lighting, and using efficient appliances. Focus on what actually moves the needle.

What uses the most electricity in a typical home?

Heating and cooling dominate most residential bills, often 50% or more. Water heating is next (10-15%), followed by major appliances (refrigerator, washer, dryer), lighting, and electronics. The specifics vary by climate, home size, and equipment efficiency.

Are time-of-use plans worth it?

Time-of-use (TOU) plans charge different rates at different times of day. They can save money if you can shift usage to off-peak hours (running dishwashers at night, charging EVs overnight). If your schedule doesn't allow flexibility, TOU plans can actually cost more. Check with your utility or supplier about whether TOU is available and makes sense for your usage pattern.
