Over the past 5 years:
I downsized to live in a 320 square foot yurt off-grid. I limited by electrical “things” to my laptop, cell phone, internet modem, 3 (LED) lights, and occasionally the blender. I have no trouble powering everything with four solar panels and a battery bank. I live in Alaska, in a location where the sun does not get above a mountain range for 7 weeks, so I use a 2000 watt gas-fired generator to charge the battery bank for about 4 months out of the year.
I built a root cellar to store water and canned goods, so I have no need for a refrigerator or freezer.
I do laundry by hand — but I would definitely go for a low-power washing machine if I had the electric and water wherewithal to do so!
I usually limit my trips into town to the grocery store (60 miles round trip) and post office to once or twice a week.
I bought a low-emission wood stove to replace the 1950’s wood stove I had.
I try to keep my car tires at the right inflation, but it’s hard to check them and use the compressor to fill them when it’s 0*F out!
I assist 2 other people in organizing a monthly Natural History Speaker Series about the natural history of the valley that I live in. This is our second winter, and this year we are asking each speaker to note something about how climate change is affecting their topic (animal ecology, glaciers, forest health/fires, etc).
