Regarding the following:
"Engage in a contract for qualified resources that have come online since January 1, 2005, for a minimum of five years, to be delivered at least annually. The contract must specify the provision of at least 50% or 100% of the project’s energy from green power, carbon offsets, or renewable energy certificates (RECs)."
Do people usually renew the certification?
If they used RECs or offsets on the previous certification do they have to purchase it again in order to renew the certification?
