Electricity from Hydroelectric Plants 2019

In 2019, Bhutan led the world in Electricity from Hydroelectric Plants, achieving a perfect score of 100%, with the global range extending from 0% to 100%. The global average for electricity generation from hydroelectric plants was 25%, while the median stood at 10.48%, highlighting significant disparities in the adoption of hydroelectric power across different countries.

Global Leaders in Hydroelectric Power

The countries at the forefront of hydroelectric power generation are largely characterized by abundant water resources and favorable topographies. Bhutan, the Central African Republic, and Lesotho all achieved 100% of their electricity generation from hydroelectric plants in 2019. This reliance on hydroelectric power can be attributed to their rich hydrological resources and limited access to alternative energy sources.

In Norway, where hydroelectric power comprised 93.62% of electricity generation, the country's mountainous terrain and high precipitation levels create ideal conditions for hydroelectric facilities. Paraguay, with 99.71%, benefits from the Itaipu Dam, one of the largest hydroelectric facilities in the world, which it shares with Brazil.

Countries with Minimal Hydroelectric Generation

Conversely, several countries showed negligible or zero reliance on hydroelectric power. Nations such as Oman, Bermuda, and Botswana reported 0% electricity generation from hydroelectric sources. The absence of significant water bodies and the presence of more viable energy alternatives, such as fossil fuels, explain these figures.

In arid regions like Yemen and Djibouti, the scarcity of water resources limits the potential for hydroelectric development, pushing these nations to depend heavily on oil and gas for electricity production.

Economic and Policy Influences on Hydroelectric Adoption

Economic factors and government policies also play crucial roles in the extent of hydroelectric power utilization. Countries like Ethiopia (94.06%) have invested heavily in hydroelectric projects as part of broader strategies to boost energy infrastructure and economic development. The Grand Ethiopian Renaissance Dam is a prime example of such efforts.

In contrast, wealthier nations with diversified energy portfolios may not prioritize hydroelectric power. For instance, Oman and Guyana rely more on oil and gas, reflecting their abundant fossil fuel reserves and established energy policies favoring non-renewable resources.

Year-over-Year Trends and Changes

The year 2019 saw notable shifts in hydroelectric power generation. Sierra Leone experienced the largest increase, with a 27.04 percentage point rise, equating to a 42.9% increase in hydroelectric generation. This surge likely results from recent investments in hydroelectric infrastructure aimed at enhancing energy access and reliability.

Meanwhile, Panama recorded the most significant decrease, with a drop of 26.36 percentage points, representing a 37.6% decline. This reduction could be attributed to changes in water availability or shifts towards other renewable sources like solar and wind energy, which are becoming increasingly cost-competitive.

Other countries such as Malawi and Turkey saw increases of 14.32% and 9.62%, respectively, as they expanded their hydroelectric capabilities. On the other hand, French Guiana and Togo experienced declines of 14.91% and 13.66%, reflecting possible environmental challenges or policy shifts affecting water resource management.

Overall, the data from 2019 underscores the critical role of geographic, economic, and policy factors in shaping the landscape of hydroelectric power generation worldwide. While some nations are expanding their reliance on this renewable energy source, others face limitations due to environmental constraints or strategic energy priorities. As global energy dynamics continue to evolve, the patterns observed in hydroelectric power generation reflect broader trends in sustainability and resource management.
