Sustainability Saturday: Bulbs and Batteries

by Mia Foster

Lightbulbs and batteries are such commonly used household items, they are considered essentials. By purchasing the correct light bulbs and batteries, we can decrease energy usage and the waste we send to landfills.

Light Bulbs

A 60-watt incandescent light bulb is the traditional style but that does not mean it is the best; these bulbs are extremely inefficient and have a relatively short lifespan. The best option is an LED light, which uses 80% less energy and has a lifespan that is 25 times that of the incandescent bulb (Davis). While LEDs have a larger initial cost than incandescent bulbs, the savings in energy bills and the decreased need to continually replace bulbs make the swap more cost-effective over time. By switching your lights to LED, you can significantly decrease the environmental and monetary impact of your lighting. If you need more motivation, EnergyStar reports that: “If every American household replaced just one standard light bulb with a high-efficiency version, the United States would save about $600 million in annual energy costs and prevent 9 billion pounds of annual greenhouse gas emissions.” (Davis) The switch might feel small, but it makes a huge difference!

Batteries

Rechargeable batteries are a more complicated issue. Simply buying and using rechargeable batteries does not make them more sustainable; according to Yale Climate Connections, a battery must be recharged 50 times before its impact is significant (Grossman). This is due to different methods and metals used for production, the energy used to charge batteries, and the different processes of disposal. For this reason, it is suggested that we use rechargeable batteries for highly used items such as remotes, cameras, and electronic toys (Schildgen). These items need new batteries more often, meaning the batteries will be charged many times, making the switch environmentally beneficial. 

Conclusion

The appliances and products we purchase and use are fundamental to the sustainability of our lives. By making educated decisions about purchases we can decrease our individual economic impacts, therefore creating a larger cumulative decrease in energy use and product waste. Small items such as light bulbs and batteries are significant!
