Question

Potato 123Pizza Beverage 456 Electricity is generated nationwide from a number of sources, including coal, nuclear, hydroelectric wind, and more. The Department of Energy publishes various reports each year related to energy Some of the reports are located at http://www.eia doe.gov/emeu/aer/elect html. One of the report is: Table 8.2b Electricity Net Generation: Electric Power Sector, 1949-2013. A subset of this table for 1980-2015 (with formatting and headings removed) is available on Blackboard in the data file is named Energy Data.dat. It is shown below. The file Energy.dat is arranged as follows: Column 1 contains the year. Columns 2-14 contain the following information: 2 pouse prt sc breaksy @2 #3 s4 %5 ^6 &7: *88 (9, ) 0,

The question is too long to be asnweed in a single window. I have provided the framework for you, which you can change a little and ge valid outputs*. I hope you understand the reason why this code maiy fail. Moreover the data quoted in the question is not available, so *i cannto test the code. If you have the data.dat file, do post the link and will update you about the stability of the code.
