Netta riduzione dei costi dell'energia risparmiata: un'analisi del Lawrence Berkeley Laboratory (California)

Dal rapporto del groppo di ricerca dell'LBL 

​We find that the cost to efficiency program administrators of saving a kilowatt-hour (kWh) averaged $0.028/kWh over the five year period. The average program administrator cost of saved energy (PA CSE) declined from $0.044/kWh in 2009 to $0.023/kWh in 2011 and then rebounded slightly to $0.028/kWh in 2013
  
​  In the commercial, industrial (C&I) and agricultural market sector, the PA CSE averaged $0.027/kWh over the five-year period but showed a modest upward trend between 2011 and 2013. In the residential sector, the PA CSE averaged $0.035/kWh in the residential sector but declined significantly from $0.071/kWh in 2009 to $0.030/kWh in 2013
