A: RECs
B: Materials with high SRI
C: Recycled water
D: Certified wood

参考答案: A

本题解释:
RECs are a tradable commodity representing the \'greenness\' of green power. They are purchased when a project does not have access to green power through their utility provider. However, this isn\'t a way to bypass purchasing power; when RECs are purchased the project still needs to pay the normal electricity bills.

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. A project in Maine can purchase RECs from any other state.

RECs cannot be purchased for a project\'s own on-site renewable energy systems. For example if a project has a solar array, the building owner could not issue RECs to themselves;Materials with high SRI help reduce the heat island effect;Recycled water supplied by municipalities helps reduce potable water use;Sustainable forestry is the environmental benefit of certified wood.
