Calculating Electricity Costs for Outdoor Holiday Lights in Seattle
The holiday season in Seattle is known for its festive environment, with homes, businesses and neighborhoods brightening the winter months. While these lights create a seasonal atmosphere, they also come with additional electricity costs. On average, Seattle homeowners spend between $50 - $150 per year on electricity for outdoor
holiday lights. Below, we’ll explore what factors contribute to these costs, how to calculate them, and tips for saving energy without losing any holiday charm.

Factors Affecting Holiday Lighting Costs in Seattle
Several elements impact the electricity costs of holiday lighting, and knowing these can
help you control expenses:
- Type of Lights: LED lights are a more efficient choice, using up to 80% less energy than traditional incandescent bulbs. According to Seattle City Light, choosing energy-efficient lighting can make a noticeable difference in your monthly bill.
- Number of Lights: The larger the display, the higher the cost. Be mindful of how many strings you’re adding to avoid an unnecessary increase in your bill.
- Lighting Duration: Many displays operate from sunset to late evening, leading to increased energy use. Reducing usage by just an hour per night can noticeably lower costs.
- Seattle’s Electricity Rates: Electricity costs in Seattle are relatively affordable compared to other cities, but winter months with higher energy usage still add up. Seattle City Light’s average rate is about $0.11 per kilowatt-hour, which can be helpful to keep in mind when calculating your costs.
Calculating the Cost: A Step-by-Step Guide
For a straightforward calculation, follow this method:
- Determine the Watts per String: Most LED holiday lights use between 4-10 watts per string, while incandescent lights may use closer to 40 watts.
- Daily Usage: Multiply the wattage of your lights by the hours they’re used each day.
- Convert to Kilowatt-Hours (kWh): Divide this number by 1,000 to convert to kWh.
- Calculate the Cost: Multiply by Seattle’s average rate of $0.11 per kWh. For example, if you’re running five 10-watt LED strings for six hours per day over a 30-day period, the electricity cost is about $1. If you used incandescent lights instead, the cost would rise to around $10.
Energy-Saving Strategies for Seattle Homeowners
- Switch to LED Lights: LEDs not only reduce electricity usage but also last longer, lowering replacement costs.
- Install Timers: Setting a timer for your lights allows you to manage how long they’re on each night. Just one hour less can make a difference.
- Optimize Your Display: Limit the number of lights or focus lighting on key areas to create an impact without unnecessary extra lights.
