Competition in Energy Supply

In 1990, the UK government privatized the electric supply
industry, and, in the years following, countries from Australia to Canada have
followed suit. Select one country where the energy markets have been
deregulated and one country that has not been deregulated. What are the
positive and negative outcomes of the process on both the supply/sales and
consumption sides of the industry? When comparing the deregulated market to one
that is regulated, do you think the approach is a success? How have price and
service been affected?
