We can not allow energy (and thus economic) poverty to stifle both our material wants/needs and ability to address the rising excess CO2 challenge. Therefore we need to frack for NG because it's better than coal. We need advanced nuclear because it's better than coal, and we need to understand that sometimes, it is "energy" backwards to embrace certain renewable energy concepts. Take for example, solar and lead acid could NEVER power the world (and transpo), but that solar and batteries with a much higher ESOI could. That corn to ethanol can't but energy crops grown from water desalinated by (advanced and cheaper) nuclear energy could.
