We should instead focus on ways to move away from coal- and oil-based energy generation methods. Do that, and the CO2 emission issue, whether it's human-caused or not, will start to go away on its own. Other related issues that affect the carbon balance, such as deforestation, would still need to be addressed.*
Wind, geothermal, hydroelectric (damns and tidal), solar, and nuclear (fission first, fusion eventually) are all viable means. I'm also hopeful that this new silicon-nanofiber lithium ion battery technology I've read about will take off. It's supposed to have an energy density 20x that of conventional Li-ion cells. That should do wonders for electric cars.
And of course, perhaps within the next 100 years, finding a superconducting that can work at room temperature, and be cheaply produced, would provide exceptional increases in power transmission efficiency. I think somewhere around 10% of all electricity generated is lost to resistance heating in power lines.
* - That is something people tend to forget about when talking about human-caused global warming. We're not only digging up loads of ancient carbon, but we're also removing vast regions of woodlands, reducing nature's ability to reabsorb it.
