In November 2006 the US Pacific Gas & Electric company launched an innovative financial incentive program in cooperation with VMware: Northern and Central California companies which achieve energy saving through virtualization are eligible for a rebate up to $4 million.
Not only the program homepage is no more there, but now Business Week reports that PG&E only paid four companies in one year and a half.
Also the number of submissions received so far, 47, is very low.
Maybe be green and save money is not that much attractive. Or maybe implementing a virtualization project takes much more time than expected.
