- Replaced most light bulbs in the house (mostly those without dimmers) with economic light bulbs (which consume 20% power compared to a normal light bulb)
- I try to recycle waste (a big problem in Israel)
- As a fan of light drinks I recently got a home soda maker, making me consume soda without consuming plastic bottles.
- I try to each less meat
- I tried to avoid buying imported food (which consumes more energy due to transportation)
