Democrat talks about Carbon Use Tax

Link Of course, the use tax is another tax. But Economists believe a use tax is more beneficial and effective than cap and trade. Cap and trade is like an incremental tax based on government managed and estimated usage levels and potential efficiencies. If the whole of carbon-dioxide generation was taxed then solar, wind, and nuclear would become much more competitive.

On a related note, Economist talks about wind and solar as if people didn't realize the fuel is free. I would think that much was obvious, no?
