Water
• The world is becoming desperately short of
freshwater, threatening our very survival.
• In South Africa, the country's water supply is
at risk.
• The nation's energy needs expected to
grow.
• Can this be turned around before it's too
late?
• Do you see energy and water imbalance
linking security (of energy and water)
towards a sustainable future.

Energy and Water
• Energy and water are intricately connected.
All sources of energy (including electricity)
require water in their production processes:.
• Energy is itself required to make water
resources available for human use and
consumption (including irrigation) through
pumping, transportation, treatment, and
desalination.
