Although some people have disputed the reality of climate change it is a certainty that minimizing CO2 emissions will have the very desirable effect of encouraging greater energy efficiency and resort to alternative energy sources. Indeed, one could reasonably suspect this is the hidden motivation behind concern about the climate.
We really need improved energy efficiency and alternative sources. It is the nature of industrial change that it takes a long long time to implement for the simple reason that it takes a long time for existing infrastructure to become too worn for use. Typically this means a lifetime for infrastructure of around 20 to 40 years. Thus the sooner we start the better. Wind and solar both have the potential to supply a lot of energy, but is will be too late if we wait until an emergency. Quite simply, the security of the nation depends upon starting energy change as soon as possible.
We are lucky that the 1973 oil crisis has already had some good effect on conservation. More is needed. Most critically, that change is needed in the personal transportation sector. Basically that means resort to electrical propulsion. Here is a
link to a recent bill in Congress that establishes CO2 emission goals.
