Conservation means if you do not need it, do not turn it on or use it. President Carter’s admonition to reduce the thermostat setting and setting a speed limit of 55 mph were conservation measures. High prices and shortages (e.g., in the California electrical crisis of 2000–2001) increase conservation, and the high price of gasoline in 2008 made more people consider fuel efficiency before they purchased a vehicle. In general, utility companies like to sell more electricity rather than have customers save energy.
