Coal-based electricity is an integral part of daily life in South Africa and globally. However, the use of coal for electricity generation carries a heavy cost for social and ecological systems that goes far beyond the price we pay for electricity. We developed a model based on a system dynamics approach for understanding the measurable and quantifiable coal-fuel cycle burdens and externality costs, over the lifespan of a supercritical coal-fired power station that is fitted with a flue-gas desulfurisation device (i.e. Kusile Power Station). The total coal-fuel cycle externality cost on both the environment and humans over Kusile’s lifespan was estimated at ZAR1 449.9 billion to ZAR3 279 billion or 91c/kWh to 205c/kWh sent out (baseline: ZAR2 172.7 billion or 136c/kWh). Accounting for the life-cycle burdens and damages of coal-derived electricity conservatively, doubles to quadruples the price of electricity, making renewable energy sources such as wind and solar attractive alternatives.

ABS Show/hide abstract
There is considerable debate in the literature over whether or not to legalise the trade in rhino horns. Here a system dynamics model is developed that considers five components: rhino abundance, rhino demand, a price model, an income model and a supply model. The results indicate that income elasticities are much greater than previously observed, while demand is relatively insensitive to price. At the same time, legalising the trade without income modification policies did not prevent extinction. The theory of s-curve growth may provide some indications of future growth patterns of Asian economies. Results suggest that, even though the demand curve for rhino horn may be downward sloping as conventional theory predicts, non-conventional demand management strategies may be more effective than price orientated demand curve strategies such as trade legalisation in curbing supply.
