Day 329 - Energy Monitor

Thought of the day: I volunteered in the annual vision screening event in Jasmine's school today. All day long, kids lined up grade by grade and had their eyesight tested by volunteers. It was my first time doing this and it had been an eye opening experience for me. I got to observe the remarkable physical and behavioral differences between kids from different grades. It's amazing how much difference a single year of age difference can make at this early stage of life. An idea just popped into my head: I want to make a photo book for Jasmine's 10th birthday so she, and we, can see how she has changed from year to year. Our minds mostly live in the present moment and it's easy for us to forget how we or our loved ones once were. "Old" photos will help us recall memories buried deep inside us and help us see the whole person and how her present self came into being. Just like annual vision charts record the vision history, photos record the life history. It would be a pretty interesting and meaningful project to reconstruct a life using photos.

Photo of the day:
Jasmine's climbing gym employs an 100kW solar system to offset a quarter of the electricity usage in the building.  It has one of David's energy monitoring devices installed and the real-time energy information is prominently displayed on the wall near the entrance. The device has a detailed memory of 30 years so you can reconstruct your energy usage history over a long span of time. Hopefully, your usage will trend down over time as you learn more about energy efficiency, pay more attention to your footprint and take steps to reduce it. So, in a way, the device captures your history of becoming a green citizen.
