The transition energy for humans in this century is nuclear power. New smaller nuclear plants that require less water can be built in remote areas with on site nuclear waste storage capacity that would last for centuries. The nuclear plants would be obsolete before they ran out of nuclear waste storage capacity. When their useful lives are over, they would simply be buried.

Wind and solar are great renewable energy sources, but their value is limited to being a great supplemental source of energy until we get both the cost of producing solar and wind electricity down and we find more efficient ways to store it. This will likely take a 100 years or more. I power my home and two cars with 32 to solar panels, so I am not against solar, but cognizant that they work better in conjunction with more reliable energy sources like nuclear energy and carbon energy.

Regarding CO2, you might find this interesting.

The world operates on CO2, it is more valuable than any other gas on the planet. There is a biological theory, than animals evolved to address the lack of CO2 and the excessive amount of oxygen in the air. While we still don't have enough CO2 in the air to maximize plant growth, we should begin to view CO2 as a resource and invest in the technology needed to convert it to portable energy.

The problem is not putting CO2 into the air, but not using it. All that CO2 is just waiting to be converted into stored energy. Nuclear energy shoud provide us time to figure out how to use CO2 to create energy cheaply and efficiently... at that point... we will have abundant energy at low cost.
