Step 2: Understanding Your Home’s Baseline Electricity Use

Once you’ve identified major energy-consuming appliances, it’s time to gauge your home's baseline electricity usage. Essentially, your baseline is the minimum amount of energy your home uses daily, even without additional or unusual activities. Understanding this baseline helps pinpoint inefficiencies and potential savings.

How Home Size Impacts Your Baseline

The physical size and structure of your home significantly influence your baseline energy consumption. Typically, larger homes consume more electricity due to increased heating, cooling, and lighting demands. For instance, a single-family house measuring around 2,000 sq. ft generally has a higher baseline usage than a compact apartment.

However, home size isn't the only determining factor. The age of your home, insulation quality, window types, and climate in your area all contribute to your baseline energy consumption. Older homes might have gaps around windows and doors, which let heated or cooled air escape, forcing your HVAC systems to work harder—and consume more energy.

Effective Ways to Lower Your Baseline Usage

Understanding your baseline energy use allows you to implement targeted strategies for reduction. Here are some straightforward actions to lower your home's baseline:

• Lighting Improvements
  Switching traditional incandescent bulbs to energy-efficient LED bulbs drastically reduces electricity usage. LED bulbs use approximately 75% less energy and can last up to 25 times longer, offering significant long-term savings.

Accurately calculating your daily electricity consumption lets you pinpoint exactly where your electricity dollars are going, enabling you to make informed decisions and potentially lower your energy costs.

The Basic Formula for Estimating Daily Electricity Usage

You can calculate how much electricity any appliance or electronic device uses each day with a simple formula:

(Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh)

Example:

Let’s say you have a television that uses 200 watts (check your TV’s manual or label) and you typically watch it for about 4 hours daily:

• Multiply wattage by hours used daily:
  200 watts × 4 hours = 800 watt-hours
• Convert watt-hours to kilowatt-hours by dividing by 1000:
  800 watt-hours ÷ 1000 = 0.8 kWh per day

This means your TV alone consumes roughly 0.8 kWh of electricity per day.

How to Find Appliance Wattage Ratings

Most appliances or devices list their wattage on a sticker or plate, typically located on the back, side, or bottom. You can also find this information in the appliance’s user manual or online on the manufacturer’s website.

If wattage isn't provided but voltage and amperage ratings are, use this alternate formula:

(Voltage × Amperage) = Watts

Creating an Energy Usage Inventory

It’s helpful to track daily usage for the main energy-consuming items in your home:

Appliance	Wattage	Hours/Day	Daily kWh
TV	200 W	4	0.8 kWh
LED Bulbs	10 W × 8 bulbs = 80 W	5	0.4 kWh
Laptop	50 W	8	0.4 kWh
Refrigerator	150 W	24 (continuous)	3.6 kWh

After estimating daily usage for each item, add them up for your total daily household electricity usage. Over time, this helps you identify opportunities for meaningful savings.
