There are concerns that emerging economies such as China, India and Brazil will overtake developed countries in their future demand for energy. This is because the demand for energy in these countries is increasing with their growing population and economy, which will in turn increase the greenhouse gas emissions of these regions as energy-related activities contribute significantly to global CO2 emissions. Invariably, if these emissions are not controlled they will restrain worldwide efforts to stabilize global temperatures.
So how big is the challenge?
The proven oil and gas reserves of the continent are estimated to be 132.4 billion barrels of crude oil and 14.5 trillion cubic meters of gas . Estimating the CO2 equivalent of these reserves reveals the continent has a potential of contributing 59.2 x 109 tonnes CO2 to existing global emissions if all the oil reserves are exploited and 33.7 x 109 tonnes CO2 if all the gas reserves are exploited. Although there are constraints to exploiting all of these resources, a report produced by Maugeri  reveals that by 2020, major oil and gas producers in the continent such as Nigeria, Angola, Libya and Algeria will be producing a total of 9.9 million barrels of crude oil per day. This production rate will translate to the emission of 4.43 x 106 tonnes CO2 daily to the global environment if the associated GHGs are not captured with carbon capture and storage (CCS) technologies. In the long-term, the uncontrolled emissions from this region will threaten global environmental stability.
Moreover, recent developments in the continent such as the discovery of larger oil fields in Angola and Kenya, the proposed development of a nuclear power facility in Nigeria and the exhaustion of renewable biomass energy sources on the continent might significantly affect future global energy scenarios and the associated GHG emissions.
Even though emissions from Africa are likely to increase in the coming years, the employment of demand management measures and increased efficiencies could help cut these emissions. The enormous benefits of these measures have propelled developed countries such as the UK to come up with energy efficiency strategies to help save energy and at the same time reduce GHG emissions.
In Africa, the deployment of energy demand management and increased energy efficiency measures such as the use of more efficient cooking stoves, cutting electricity consumption, minimising the use of energy for transport, water savings (water supply requires a lot of energy), purchasing less energy intensive gadgets and adopting new fuel economy standards will contribute to energy savings.
Government policies should be directed at creating a framework for these measures and implementing them to reduce the energy use and demand of the continent, which will help cut GHG emissions from the continent.
