Renewable Energy: Wind • Total load is ~1,246,000 MWh/year • Purchased 1,245,774 MW Green-‐e RECS
• Divided between FY 2014 and FY 2015 • Thus, 50% of annual load from renewable
energy for next two years • Cost is only $0.000805 per kWh
• Advantage of purchasing electrons and RECs separately: best price for both • Traded in two different markets
