gasoline and diesel used in cars releases through the exhausts carbon dioxide into the

atmosphere. The build-up of carbon dioxide and other greenhouses gases such as methane and

nitrous oxide contribute to climate change.

Electricity generation is also a significant contributor of carbon dioxide emissions into the

atmosphere. Approximately 40% of global CO2 emissions stem from electricity generation
through the combustion of fossil fuels to generate the heat needed to power steam turbines.

Carbon dioxide (CO2) is the primary heat-trapping “greenhouse gas” responsible for global

19
warming.

The use of renewable energy will reduce the amount of carbon dioxide emissions being released
into the atmosphere.

Energy Security

Energy Security means the reliable supply of energy and access to energy resources and fuel in

20
the required quantity and quality at reasonable prices. Energy security is particularly important
because of dwindling fossil fuel reserves and climate change. As energy consumption increases

and supply decreases, this will cause countries to look to other alternative sources of energy to

meet their energy demand. A diversified energy mix that includes renewable energy will bring

benefits of security of supply.
