Found on page 43, had to convert therms to gigajoules. Purchased electricity - non-renewable sources
1 Therms = 0.10548 GJ
1 MWh = 3.6 GJ
(Calculation of non-renewable energy source: (64,731,790*0.10548) - (94,990*3.6) = 6,827,909.2092 - 341,964 = 6,485,945.2092)

"Although we met our GHG emission target early, we are continuing our efforts to reduce our impact. Each year, we purchase 100% renewable energy for all our North American operations. We support renewable energy with the purchase of Green e-certified renewable energy certificates (RECs). In 2017, we purchased 94,990 MWh of wind and solar energy, including some within the same grid region as our Windsor, Virginia, plant, which allows us to report zero Scope 2 emissions in our greenhouse gas footprint."
