Maybe the law will read that on the days when the outside temperature is less than 65 degrees Farenheit, there will be no tax for that day at that location. However, if the "energy Nazis" see that your windows were open on that day, the tax will be doubled.
Conversely, on days when the outside temperature is greater than 75 degrees Farenheit, the tax will be doubled.
When the outside temperature is between 65 and 75, there will be no government on that day.
This would be change we could believe in, as long as the temparature was beween 65 and 75, espeially if you live in California.
