Intergenerational equity in energy resource utilization refers to the ethical and economic principle that current generations should use energy resources in a manner that does not compromise the ability of future generations to meet their own energy needs. In energy economics and planning, this principle is closely linked to sustainable development and long-term resource management. Energy resources such as fossil fuels are finite, and their overexploitation can lead to resource depletion, environmental degradation, and increased energy insecurity for future populations. The principle emphasizes fairness in resource distribution across generations. It suggests that present users of energy resources should bear the environmental and economic costs associated
