Given information

Given:- 

One watt (W) = 1 joule/second ,

1 gigwatt  = watts.

Step-by-step explanation

Step 1.

From 2009 through 20212, the area between the curves in Fig. 1 is roughly a right triangle with a base of 3 and a height of 40.

 

From 20212 through 2020, the area is roughly 8 by 40 rectangles.

 

From 2020 through 2030, the area is roughly a trapezoid with height 10 and bases 40 and 27.

 

This, additional energy produced is 

 

 

Thus, additional energy produced

joules in the years 2009-2030.
