Projections from the International Energy Agency show global energy demand growing by close to 30 percent by 2020, setting the stage for massive growth in the carbon dioxide emissions that are warming our planet. But dramatically ramping up energy efficiency would allow the world to not only avoid growth in energy demand but actually reduce global demand to below 2006 levels by 2020.
We can reduce the amount of energy we use by preventing the waste of heat and electricity in buildings and industrial processes and by switching to efficient lighting and appliances. We can also save an enormous amount of energy by restructuring the transportation sector. Many of the needed energy efficiency measures can be enacted relatively quickly and pay for themselves.

The Bush Administration bailed out GM on Friday, after pushing the prospect of bankruptcy as the most reasonable option. The most compelling language in the bailout agreement: A mandate for electric cars or fuel efficient models? Not at all. The government has focused in on forcing GM to get rid of its corporate jets, which drew little notice until the Big 3 CEOs flew to Washington to be upbraided by lawmakers.
The legislation had little to say about fuel efficiency, electric or hybrid cars, or the feasibility that a loan to GM will do anything to resurrect the struggling company. In regard to emerging technologies, the legislation requires merely that GM “intend” to “commence domestic manufacturing of advanced technology vehicles.”

With the dramatic increase in oil prices earlier this year translating into higher prices at the gas pump in the United States, concerns over U.S. dependence on foreign oil are once again part of the national discussion on energy security. Combined with the growing understanding that carbon emissions from the combustion of fossil fuels are driving global climate change, the debate is now focused on how to restructure the U.S. transport system to solve these two problems.
While the idea of running U.S. vehicles on natural gas has lately received a great deal of attention, powering our cars with green electricity is a more sensible option on all fronts—national security, efficiency, climate stabilization, and economics.
Having a fleet of natural gas–powered vehicles (NGVs) would simply replace U.S. dependence on foreign oil with a dependence on natural gas, another fossil fuel. The United States has scarcely 3 percent of the world’s proved natural gas reserves, yet even without the increased demand that would result from a fleet of natural gas cars, the country already consumes nearly a quarter of the world’s natural gas. At current rates of consumption, U.S. proved reserves would only meet national demand for another nine years.
U.S. natural gas production has remained relatively constant over the last two decades and is unlikely to increase over the long run, despite growing consumption. Consequently, any rise in demand is likely to be met by increasing imports. Since the late 1980s, U.S. net imports of natural gas—primarily from Canada—have tripled. The U.S. Department of Energy projects that by 2016 the majority of U.S. natural gas imports will come from outside North America.
