IMHO, it would probably be helpful to be aware of, and study, the numerous articles on "peak oil". I know it's a scary subject, and one should avoid overeacting to some of the more pessimistic ideas. However, IMO many of the articles are written by well meaning and reputable individuals who are attempting to come to terms with the projected peak in world oil production.
Luckily, Alberta is probably one of the best places on earth to be, if or when a shortage of oil develops and becomes critical, because of our huge reserves of oil in the tar sands. We also have very large reserves of near-surface coal which could provide us with needed energy for hundreds of years.
