Typical examples include: the expectation of high return on investment (short
payback period); high capital costs and long
project development times for some measures; lack of access to capital for energy
efficiency improvements and feedstock / fuel change; fair market value for cogenerated electricity to the grid; and costs / lack of awareness of need for control of HFC leakage.
But financing
efficiency projects is more complex, and has received much less attention from investors, because the
payback is spread more diffusely — among thousands of companies and individuals.
