It's not entertaining, it's counterproductive. Instead of actually doing something constructive she posts nonsense on her website about how important it is that everyone turn their thermostat to 78° F when they are home and 85° F when away. This is not constructive. In Malibu this may work but where I live it is currently 105° and 88% relative humidity. If I turn my A/C to 85° F my house will be like a sauna when I come in and I will then have to break another one of Barbara's "rules" by running my A/C between 4 PM and 6 PM just to make my room comfortable. It would be more efficient for me to maintain a comfortable temperature all the time. I set mine for 80° F because that is where I am most comfortable. Her individualistic approach is counterproductive and hypocritical. If she really believes that an individual approach is what works how can she exempt herself? She's a loon who should shut the fuck up about the environment because she is adding nothing to the debate, she is not increasing anyone's consciousness in a meaningful way since her way, the individualistic way, is doomed to fail. Her hypocrisy demonstrates why it is a failed approach and is a fair criticism.
