Many energy advocates are concerned about the construction of new conventional electricity generation. This is not only due to the harmful effects of mining, using, and disposing of the waste from coal, natural gas, and uranium, but also because there is only so much electricity demand. My Alt Energy Stocks column this week exproles the possibility of utilites building too much conventional generation to need any renewables at all.
Utilities often say that they will have trouble meeting future demand… this was the justification for the coal plants (now mostly replaced by nuclear) planned by TXU. But these projections massively underestimate the potential of imporved energy efficiency which most studies put at about 1.2% acheivable savings per year, but I believe could be much higher with changes to the regulatory landscape.
