Here are some things I've noticed recently that aggravated me:

1. Self-flushing toilets. Every time I use one, it flushes at least twice. The sensors must not be functioning properly and the toilet ends up wasting water. This technology seems counter productive.
2. Escalators that run all the time....even when no one is using it!
3. The public high school in my area, as well as many office buildings, keep the lights on during the night.
