Electricity from Hydroelectric Plants 2019

In 2019, Lesotho led the world with a full 100 in "Electricity from Hydroelectric Plants," marking the global range from 0.00 to 100.00. This metric highlights the extent of renewable energy production from hydroelectric sources. The global average for electricity from hydroelectric plants was 24.43, with a median value of 15.00, reflecting significant variation in reliance on this renewable energy source worldwide.

Geographic and Economic Influences on Hydroelectric Reliance

The reliance on hydroelectric power is strongly influenced by geographic and economic factors. Countries such as Lesotho (100), Bhutan (99), and Paraguay (99) have abundant river systems and topographies conducive to hydroelectric power generation. These nations have capitalized on their natural water resources, often due to limited access to other energy forms, and have developed infrastructure that supports a high percentage of electricity generation from hydro sources.

In contrast, countries like the United States Virgin Islands, Barbados, and British Virgin Islands each reported a hydroelectric contribution of 0. This is attributable to their geographic limitations, such as small landmass and lack of significant freshwater resources, which inhibit the development of large-scale hydroelectric facilities.

Hydroelectric Power and National Energy Policies

Government policies and investment in renewable energy infrastructure also play pivotal roles. Norway, with a hydroelectric reliance of 93, exemplifies how strategic government support can leverage natural resources to achieve nearly complete reliance on hydroelectric power. Norway’s energy policy has long prioritized sustainable practices and the development of renewable energy resources.

Similarly, Albania (95) and Tajikistan (94) have benefited from government-led initiatives to maximize the potential of their water resources. In these countries, hydroelectric power not only meets domestic needs but also positions them as energy exporters in their respective regions.

Hydroelectric Power's Role in Economic Development

Hydroelectric power can significantly contribute to economic development, especially in regions with limited resources. For instance, Paraguay (99) benefits economically from the Itaipu Dam, one of the world's largest hydroelectric projects, which not only supplies domestic energy but also generates revenue through electricity exports to neighboring countries like Brazil.

In Zambia and Malawi (both at 93), hydroelectric power is a cornerstone of energy policy, providing affordable electricity and supporting economic activities. The availability of reliable and inexpensive power has been crucial for industrial growth and improving living standards in these nations.

Stability in the Hydroelectric Sector

The year-over-year data from 2019 shows no significant changes in the reliance on hydroelectric power globally, with an average change of 0.00 (0.0%). This stability indicates mature infrastructure in countries heavily reliant on hydroelectric power, such as Lesotho, Bhutan, and Paraguay, where the potential for expansion is limited by existing capacity and geographical constraints.

However, the lack of change also highlights challenges in diversifying energy portfolios in countries with 0 reliance. For these nations, transitioning to renewable sources like hydroelectric power requires significant investment and infrastructural development, often hindered by economic and technical barriers.

In summary, while hydroelectric power remains a critical renewable energy source for many countries, its reliance varies widely due to geographic, economic, and policy-related factors. Understanding these dynamics is essential for assessing future trends in global energy production and sustainability efforts.
