How to Create a Low-Cost, High-Efficiency Electrical System For Your Home


Making your home's electrical system more efficient can save you money on your energy bills while also being better for the environment. With some planning and strategic upgrades, you can create an electrical system that operates smoothly and cost-effectively without breaking the bank. In this guide, I will walk through the key steps I took to rework the electrical system in my home to make it low-cost and highly efficient.

Audit Your Current Electrical Usage

The first step is to understand how electricity is currently used in your home. Here are some tips on how I conducted an electrical audit:

Upgrade Inefficient Appliances and Devices

Once I understood where and how electricity was used, I was able to pinpoint the biggest offenders to upgrade first.

Improve Insulation and Air Sealing

Ensuring your home's insulation and air sealing is up to date is one of the most cost effective ways to boost efficiency. Here's what I did:

Install a Programmable Thermostat

Replacing my old thermostat with a programmable smart thermostat allowed me to set customized heating and cooling schedules to match my family's patterns and minimize energy waste. I chose the Ecobee SmartThermostat with voice control. The efficiency gains paid for the thermostat cost in under a year.

Audit and Improve Your Electric Panel

Having an electrician conduct an audit of your home's electric panel and wiring can identify safety issues and efficiency gaps. Here are key things I did:

Install Solar Panels (If Cost Effective)

I ran the numbers and determined a solar PV system could save me over $1,000 annually on electric bills. With federal and state incentives, the system will pay for itself in 9 years. Over the 25+ year lifespan, I will generate over $30,000 in energy value. And I'm using clean, renewable energy!

Monitor Usage and Make Continual Improvements

I installed the Sense home energy monitor. This shows me real-time data on how much energy all my home systems and appliances are using. I can quickly spot any anomalies and determine additional areas to target for efficiency upgrades. Continuous improvement over time will ensure my home's electrical system stays optimized.


With some research, planning, and strategic upgrades, I successfully created a low-cost, highly efficient electrical system for my home. Key steps were auditing usage, replacing inefficient appliances and devices, improving insulation and air sealing, installing a smart thermostat, upgrading the electric panel, and adding solar panels.
