Keep the positives
Although we all welcome the much lower prices for gasoline, we hope that progress continues on the positive moves that were motivated partly by high fuel prices.
It still makes sense for economic, political and environmental reasons to develop alternatives to fossil fuels. Much of the oil we use is controlled by governments hostile to the United States. Some of these governments even provide support for terrorists.
Besides developing alternatives, the high cost of fossil fuels encouraged conservation practices. This remains a positive thing to do. There is an environmental cost to overuse of fuels.
The plunge in prices only underscores the facts that fuel prices are unstable. We shouldn't be complacent about the cheapness of fuel, relative to the recent past.
