Objective 6: Discuss the need for sustainable energy.

All societies require energy services to meet basic human needs
(for example, lighting, cooking, space comfort, mobility, and

communication) and to serve productive processes. (see SDGs);

however, its generation and use may have negative

consequences for development, particularly for social and

environmental issues. These issues include the following:

• Environmental Change

Issues of concern include fuel consumption in power generation; carbon dioxide emission;

copper waste generation; aluminium waste generation; water consumption; and greenhouse gas

emission; and the need for replacement/substitutes for non-renewables.

• Climate change

Since approximately 1850, global use of fossil fuels (coal, oil, and gas) has increased to dominate

energy supply, leading to a rapid growth in carbon dioxide (CO ) emissions. Energy accounts for
two-thirds of total greenhouse gas, so efforts to reduce emissions and mitigate climate

change must include the energy sector. Globally, the primary sources of greenhouse gas
emissions are electricity and heat (31%), agriculture (11%), transportation (15%), forestry (6%)

and manufacturing (12%). Energy production of all types, accounts for 72 percent of

all emissions.

Our climate challenge is a shared global challenge – and it is largely an energy challenge. Energy
accounts for over two-thirds of global greenhouse gas emissions. This means energy must be at
