Answer:
The perceived economic impact of CO2 generated per year by lighting sstem is $8164.67.
Explanation:
The CO2 requirement for the plant is:
Amount of CO2 per year = (2.4 lb / KWh)(300,000 KWh)
Amount of CO2 per year = (720000 lb)(1 ton/ 2204.62 lb)
Amount of CO2 per year = 326.59 ton
The perceived economic impact of CO2 generated per year will then be:
Economic Impact = ($25 / ton)(326.59 ton)
<u>Economic Impact = $8164.67</u>
