Excel reggresion time series

Dear all,

I have a question regarding data input in excel in order to run a regression.
The thing is that I have available data for 28 European countries in period from 1990 to 2000.
How do I set data?
Do I need to run regresison for every country seperately (28times) or can I put all data together?

Is this set of data possible to run a reggresion on ?
Output= dependent variable, Energy & Employment = explanatory


Thanks a lot!
