The electricity wasted in a year is 65. 7 KW

<h3>How to determine the value</h3>

From the information given, we have that;

We are to determine electricity wasted for a year.

First, we determine the hours it is light on in a year

4 hours is to 1 day

x hours is in 365 days

cross multiply

x = 365 × 4

x = 1460 hours

If 180 Watts = 4 hours

x = 1460 hours

x = 65700 Watts

In KW

= 65700/ 1000

= 65. 7 KW

Thus, the electricity wasted in a year is 65. 7 KW
