Answer:
2.6784x10^8 mega joules
Explanation:
joules = watts * seconds
Electrical Energy = Power x Time
Electrical Energy (joules) = watts x seconds in a day
seconds in day 86400 seconds
3100 megawatts = 3.1x10^9 watts
Electrical Energy (joules) = 3.1x10^9 x 86400
Electrical Energy (joules) = 2.6784x10^14 joules
2.6784x10^14 joules = 2.6784x10^8 mega joules
