The world is continuing to use more and more carbon fuels and emitting more and more CO2, particularly in Asia and soon in Africa. The Mauna Loa CO2 readings confirm that CO2 in the atmosphere has risen steadily since 1958 when they were first started. Temperature, however, is no longer climbing.

Correct, but the problem is a "renewable" power source that will make us energy independent. While solar, wind, or a thermal heat source, such as in Iceland to produce hydrogen consumes more energy than created, it IS a "renewable" source of portable power that doesn't produce CO2.
Solar, as a practical source of power for automobiles, does not work, considering the needs of transportation. Natural gas is already being used buy industry and a limited amount of trial transportation applications and is not "renewable". Batteries, as Stevez has informed me, create a toxic disposal problem. Only hydrogen is clean, renewable and doable using the earths natural energy.
Nuclear, of course, is a good source of energy to produce hydrogen, but selling the usage to the populace may be an insurmountable task.
