Under H.R. 2454, electricity demand is reduced significantly and allowance prices are not high enough to drive a significant amount of additional low- or zero- carbon energy (including nuclear, renewables, and CCS) in the shorter-term, excluding the technologies with specific financial incentives (e.g., CCS).
If you look at the graph according to this analysis there would be more renewable resources generating electricity without the cap. We'll be using less electricity becuse of inflated costs, the demand for growth in the energy sector will drop significantly. This bill does more to shape habits than actually provide any benefits.
