It was a typical summer-Sabbath dilemma--we knew that it wouldn't be hot enough for us to need the air conditioner on Friday night, but that it
would be hot enough on Shabbat afternoon.
The problem was that I could no longer justify using the traditional Shabbat work-around.
This planet is currently facing the most serious ecological disaster of my lifetime, namely, global climate change. How could we waste precious resources by running our air conditioners for 25 hours straight, rather than turning them on and off as needed? Even the energy-saving setting on an air conditioner uses electricity, as do the numerous timers that we've always used.
And so, for the first time in over 30 years, I unplugged the hot-tray after dinner on Shabbat.
The only appliance that we left plugged in for the entire 25 hours was the urn, which we used in order to avoid violating the prohibition against cooking on Shabbat.
Not cooking on the Sabbath continues to make sense to me.
Leaving an air conditioner on for 25 hours just to avoid pressing a button does not.
We will continue to turn off our television and our computers before Shabbat to protect the health of both the earth and ourselves--our eyes need a break from the constant glare, our minds from the frequent intrusion of often-bad news, and our souls from the "glass mechitzah" that tempts us to forego in-person conversations. And we'll continue to restrict the use of our phones to emergency calls only.
But we'll no longer flip out about flipping on a light switch on Shabbat. Given a choice between respecting rabbinic regulations or protecting HaShem's creation, we'll choose to protect HaShem's creation.
