On May 2, Senate Energy and Natural Resources Chairman Ron Wyden (D-OR) sent a letter to the White House advocating for the increased use of Energy Savings Performance Contracts (ESPCs) in order to reduce federal energy consumption more quickly. Wyden said ESPCs reduce the cost of energy and do not require any upfront cost to the taxpayers. The Obama Administration pledged in 2011 to sign $2 billion worth of ESPCs by 2014 but has only entered into $500 million worth of contracts to date.
