There are two more measures we need to pursue seriously. The first is conservation. Remarkable achievement has been made over the past two decades in improving the efficiency of home appliances, air conditioners, furnaces and the like. New homes are much more energy efficient. Still, there is much that needs to be accomplished with homes, offices, factories and, of course, transportation system, including automobiles.
Conservation is always directly related to the cost of energy.
In California a few months ago, utilities raised their rate to cover their actual costs for power. Utilization fell dramatically. He rolled the rates back and consumption went back up. Sheltering consumers from the true cost of energy promotes waste. Last but not least, the government needs to have as a priority developing the technology and infrastructure that will be necessary for a hydrogen economy.
