This article aims at highlighting three broad conceptions of how the global energy industry has a direct relationship with the climate. This energy-climate union is fraught with some peculiar problems. Broadly, these issues are: the dilemma, the trilemma and the quadrilemma. ‘Why is this important?’, one may ask. It is only by understanding the main problems in this relationship that one may propose suitable pathways for resolving them. The last two (the trilemma and quadrilemma) also act as frameworks for resolving the main challenges posed by energy systems around the world.

The Dilemma

The Trilemma

Meanwhile, the UN Global Goals on affordable and Clean Energy (SDG 7) urge us to change our current reliance on fossil fuels to more sustainable and less harmful ways (15). This goal is commendable but faces practical complexities. Energy that is cheap may not be good for the environment (coal and gas), sustainable may be intermittent, variable and insufficient to power industrial uses (renewable energy), and sustainable energy may not be locally available leading to continued use of fossil fuels for self-reliance (energy security). The ‘Energy Trilemma’ is important because it states both the problem and provides a framework to deliver the energy transformation needed to make sustainable energy systems a reality. How? By ensuring that energy decisions consider these competing interests and are not guided only by profit, financial considerations, or the need for energy self-reliance. On the bright side, advancement in the solar energy sector has also resulted in solar energy being reported as the cheapest electricity in history.
