U.S. emissions are down, and without a Kyoto-style command and control system.
This is good news. Human activity is increasing carbon dioxide levels in the atmosphere, and the long term consequences are unpredictable and possible severe. We do not need to wreck our economy, or turn over control of our energy industry to a vast carbon bureaucracy as Al Gore would have us believe. We should look for free market solutions to reduce greenhouse gas emissions. Unlike Kyoto, they might actually work.
My personal hope is that advances in battery technology will someday soon allow cars to travel the same distance as a tank of gas, and recharge within 10 or 15 minutes. Until those batteries come along, we're not going to be driving electric cars. So, who trusts Congress to get that job done, and who trusts market capitalism?
