Q

PV panels at health project
2,000,000 kWh of annual electricity @ $.075/kWh
50,000 Therms of annual gas @ $.75/therm
150 kW PV array will generate 200,000 kWh of electricity/year.

How many points would team earn for EA-C Renewable Energy Production?

A

2 points - 1 point = 1-4%, 2 point = 5-9%, 3 point = 10%

Annual Energy Cost = (2mil kWh x $.075/kWh) + (50k therms x $.75/therm) = $187.5K

Cost of Renewable Energy = (200K kWh x $.075/kWh) = $15K

% Renewable Energy Cost = (15k/187.5k) = 8%
