Implementation -
Eligible types of Renewable Energy (as defined by the CRS: Center for Resource Solutions) = solar, photovoltaic, wind, geothermal for heating and electric, biomass, biogass, and low-impace hydroelectric
Baseline Electricity Use: 1) Determined by consumption based on EAc1 2) Use DOE (department of energy) and CBECS (commercial building energy consumption survey)
a) Case 1: in states with an OPEN electrical market: select 35% GREEN-e certified power provider with a 2yr contract
b) Case 2: in states with a CLOSED electrical market: Enroll in a Green Pwer Program for 35% of the electrical energy
c) Case 3: where green power is NOT available: 1) purchase RECs (tradable Renewable Certificates): purhase quantity of RECs equivalent to 35% of predicted annual electrical consumption for a 2yr period (this equals 70% of the projected annual electrical consumption if all RECs are purchased at one time)
