CFLs in the Sherwin Houshold
0 likes2,063 views
The Sherwin family of Menlo Park faced a high electric bill of $506, prompting a deep dive into their energy consumption and the installation of various energy-efficient technologies such as motion detectors and CFL bulbs. Despite these efforts, they discovered significant savings potential through further reductions in energy usage and investing in solar energy, which would cost $20,616 but save $124 monthly. The family also shares insights on successful lighting products and emphasizes the importance of monitoring tools to track real-time energy consumption.
