This lack of access disproportionately affects people in rural and remote areas, particularly in sub-Saharan Africa and South Asia.
What is Energy Affordability?
Energy affordability refers to the ability of households and communities to access energy without financial hardship. It is typically measured by the proportion of a household’s income spent on energy bills. For many people, energy costs can be a significant burden, leading to energy poverty, where they cannot afford enough energy to meet their basic needs.
Energy affordability challenges are compounded by rising energy prices, which are influenced by factors such as fossil fuel price volatility, geopolitical tensions, and natural resource depletion. Energy affordability is particularly crucial for low-income households, as they are often the most vulnerable to price fluctuations and service interruptions.
The Link Between Energy Access and Affordability
Energy access and affordability are deeply intertwined. Without access to affordable energy sources, people are often forced to rely on inefficient and polluting energy options, such as kerosene lamps or wood stoves, which are not only more expensive in the long term but also harmful to health and the environment. Moreover, high energy costs can prevent households from accessing critical services like education and healthcare, further exacerbating social inequality.
Key Challenges in Energy Access and Affordability
Several challenges contribute to the lack of energy access and affordability worldwide:
1. Geographical Barriers
