In 2022, Lesotho's electricity consumption was characterized by a significant proportion of low-carbon energy, with more than half (around 54%) coming from hydropower. This indicates a strong reliance on domestically generated clean energy. However, nearly half (46%) of Lesotho's electricity is still imported, which could mean dependence on foreign energy sources, some of which may not be low-carbon. Overall, while Lesotho makes relatively good use of low-carbon hydropower, there is substantial room for improvement in generating more clean electricity locally to reduce reliance on imports.
To increase low-carbon electricity generation, Lesotho can look towards successful strategies employed by countries with a high percentage of clean energy. For example, Denmark generates over 60% of its electricity from wind power, demonstrating the potential for wind energy in similarly windy regions. Although Lesotho does not currently utilize nuclear energy, it could consider the example of France, where nuclear power provides a substantial 67% of electricity, showing the viability and benefits of this clean energy source. Given Lesotho’s geographical similarities with countries like Denmark and other regions that have succeeded in wind and solar energy generation, it’s feasible for Lesotho to focus on expanding these technologies to diversify and strengthen its low-carbon portfolio.
Lesotho's journey with low-carbon electricity, particularly hydropower, saw modest growth and some years of stagnation between 2000 and 2019. The early 2000s experienced a slight but steady increase in hydropower, with minor increments such as 0.1 TWh in 2000 and another 0.2 TWh in 2005. However, many subsequent years showed no significant increase, and even a minor setback in 2011 with a decrease of 0.2 TWh. By grouping these years into broader phases, it becomes evident that the period from 2006 to 2019 saw minimal changes in hydropower generation. This history suggests that there has been insufficient development and investment in low-carbon energy, highlighting an area ripe for strategic improvement and expansion in the future.
