In 2021, Tajikistan's total electricity consumption was dominated by low-carbon sources, particularly hydropower, which generated 18 terawatt-hours (TWh). This was complemented by a minor contribution from fossil fuels, producing 1.73 TWh. Collectively, low-carbon and fossil sources provided nearly 20 TWh of electricity for the year. Despite the commitement to clean energy sources, Tajikistan's electricity generation is still below the global average of 410 watts per person. This may have effects such as limiting industrial growth, technology use, and overall quality of life for inhabitants due to less reliable access to electricity. Unavailability of reliable power may also hinder the growth of small and medium enterprises in the country.
In considering ways to increase low-carbon electricity generation, Tajikistan might look to successful countries for inspiration. For example, the People's Republic of China and the United States have significantly developed wind and solar energy, producing 964 TWh and 425 TWh respectively. Close to Tajikistan's conditions, Brazil has maximised wind power, generating a significant 94 TWh from this source. India, also a developing nation, has made significant strides in harnessing solar power, generating 120 TWh. These examples show that, despite the challenges, it is possible to increase low-carbon energy generation significantly. Expanding the use of both wind and solar power could elevate Tajikistan's electricity generation closer to the global average while maintaining a commitment to sustainable energy.
There have been various changes in Tajikistan's low-carbon energy production over the decades, particularly with regards to hydropower. In the 1990s, changes in hydropower generation fluctuated, with upturns such as a 1.1 TWh increase in 1993, but also downturns such as a 2.4 TWh decrease in 1995. The early 2000s also saw fluctuations, with a notable 1.2 TWh decrease in 2000 followed by increases in subsequent years. The last two decades of the 21st century, however, showed an increasing tendency, with regular upticks including a 1.3 TWh increase in 2018. Throughout this period, there were few dips, the most significant being a fall of 1.1 TWh in 2020. Nevertheless, these changes showed an overall positive trend in low-carbon energy production in Tajikistan.
