Lack of Energy Efficiency Holds Back Entire Economy

(Hardesty, Energy Manager Today (2013))

The American Council for an Energy Efficient Economy disclosed that US economy is not so energy efficient. 

Only 14% of the total high-quality energy was converted to useful work in 2010. It is important to look at both available energy (exergy) and the unavoidable loss of energy (anergy). The rate of exergy conversion grew only two percentage points in the previous three decades, as it started at 9% rate of exergy conversion in 1950. 

Taking both into account, the lack of energy efficiency may be one of the significant reasons that hold back the economy. Without investment policies to improve exergy efficiency , the report suggests that the annual productivity of the economy may weaken, and further growth in GDP as well.
