Given that global energy use today is still dominated by fossil fuels, there is an urgent need to rapidly reduce its use in order to avert serious climate change. However, the alternatives to fossil fuels—renewable and nuclear energy—are more expensive, and have so far done little to displace fossil fuels. Accordingly, reducing energy use must play an important part in both averting climate change and avoiding the depletion of high energy return easily recoverable fossil fuel reserves. This paper examined both the potential and barriers to the adoption of energy reduction measures, with particular attention to domestic energy and passenger transport. The main finding was that energy efficiency approaches alone are unlikely to deliver anywhere near the energy reductions needed in the limited time available. Instead, most energy reductions will have to come from energy conservation, involving less use of energy-using devices, including private vehicles. Achieving such reductions will require changes in lifestyles, especially for residents of OECD nations.

Energy efficiency improvement is believed to be an effective means of reducing energy consumption thereby reducing green-house gas emission and as well promoting sustainable economic development. Therefore, ascertaining the energy efficiency level will guide policy makers on the right kind policy intervention that will guarantee energy security, climate change mitigation and sustainable growth and development. The study employed a multivariate regression technique to estimation of the impact of a change in the energy structure on aggregate energy efficiency and economic growth. It was revealed in the study that, though an increase usage of fossil fuel is an important factor input for economic growth, however, it is inimical to the efforts aimed at combating climate change. The study also revealed that the marginal efficiency of the energy inputs is important for ensuring increased output as well as sustainable energy supply. Energy efficiency was seen as a mechanism for improving optimal energy utilization. Therefore, improving the level of energy efficiency will significantly assist in providing clean energy coupled with achieving sustainable development goals. This will benefit the nation in terms of ensuring energy security together with climate change mitigation. Policy makers should also focus more on investing in energy efficiency promoting technologies in order to reduce the per capita energy consumption without compromising the economic output level.   Received: 16 June 2021 / Accepted: 7 November 2021 / Published: 3 January 2022

Fossil Fuel Energy

As the unacceptable results of continued fossil fuel combustion on climate change become ever clearer, a need to dramatically reduce greenhouse gas (GHG) emissions by aggressive energy conservation and immediate transitioning global civilization to alternative energy sources has become evident. Many energy technologies are capable of displacing significant volumes of fossil fuels. Unfortunately, neither the enormous scale of the current fossil fuel energy system nor the necessary growth rate of these technologies is well understood within the limits imposed by the net energy produced for a growing industry. This technical limitation is known as energy cannibalism and refers to an effect where rapid growth of an entire energy producing or energy efficiency industry creates a need for energy that uses (or cannibalizes) the energy of existing power plants or production plants. Thus during rapid growth, the industry as a whole produces no net energy because new energy (or conserved energy) is used to fuel the embodied energy of future power plants or production facilities. Such life cycle analysis is also valid for GHG emissions. All current technologies are dependent to some degree on fossil fuel energy and thus also contribute to emissions. This paper expands earlier work to generalize the GHG emission neutral growth rate limitation imposed by energy cannibalism to any renewable energy technology or any energy efficiency technology. Conclusions and recommendations are made from the analysis to assist decision makers in optimizing deployment of technologies on large scales to reduce GHG emissions to safe levels without overshoot.
