What statement is true about RECs?
A: RECs are reduced from utility bills
B: RECs depreciate in value
C: RECs are tradable commodities
D: RECs provide electricity

参考答案: C

本题解释:
RECs are not reduced from utility bills;RECs do not lose value; RECs represent the reduced emissions of renewable energy compared to conventional fossil fuels. RECs are sold separately allowing people to purchase the \'greenness\' of the electricity. This allows anyone to purchase an REC even if the power to their building is not green power.

RECs have no geographic constraints, because they are sold separately from electricity;RECs are not electricity
