Question

liam is taking time over the weekend to install motion sensors on his bathroom faucets and the fans in his home. what is most likely his motivation for installing this new technology?

○
to incorporate non - renewable resources into his home

○
to benefit from the federal solar tax credit

○
to wow his friends with his new gadgets

○
to save energy by turning off items not in use

Explanation:

Motion sensors on faucets and fans can automatically turn off these items when no motion (indicating no use) is detected. This helps in saving energy. Non - renewable resources incorporation is not relevant here. Federal solar tax credit is for solar - related installations. Just "wowing friends" is a less likely and superficial motivation compared to energy - saving.

Answer:

to save energy by turning off items not in use
