Hydroelectric power is one of the main sources of renewable energy worldwide, and its use is increasing as countries look to reduce their reliance on fossil fuels. Hydroelectricity is a clean energy source, generated from the natural flow of water, and it doesn't use up water as it operates. It is also one of the most cost-effective means of generating electricity. However, it is difficult to say whether one source of renewable energy alone can replace fossil fuels. It is more likely that a combination of sustainable energy sources could replace them.

Hydropower is a renewable energy source
Hydroelectric plants do not use up water as they operate, making hydropower a completely renewable electricity source. As the water cycle naturally runs, hydropower will always be a viable way to generate electricity. Hydropower is also a reliable source of power because plants can store large amounts of water in reservoirs. This means that hydropower can be used to support more intermittent energy sources, such as wind and solar power.
Hydropower has the largest electricity generation capacity compared to other renewable energy sources. In 2017, 1.5 million people worked in the hydropower sector, and another 290,000 in the small hydropower sector. In Norway, 99% of the country's electricity is generated from hydropower. The Gorges Dam in China is the world's largest hydropower plant, producing enough energy to supply between 70 and 80 million households.
However, it is difficult to say whether one source of renewable energy alone can replace fossil fuels. It is more likely that a combination of sustainable energy sources could replace them. For example, solar power is more accessible to the average individual as it can be installed on roofs with relative ease. Nevertheless, hydropower is a clean and cost-effective energy source that can make a big difference in the race to find suitable energy sources to replace fossil fuels.

Hydroelectric plants don't use up water
Hydropower is one of the main sources of renewable energy worldwide. Countries are installing hydropower plants at an increasing rate to provide power to their people and reduce their reliance on fossil fuels. Hydropower is a renewable energy source derived from flowing water. Its history can be traced as far back as ancient Greece, where 2,000 years ago waterpower was used to operate wheels for grinding grain. Today, hydropower is one of the most cost-effective means of generating electricity. For example, in Norway, 99% of the country's electricity is generated from hydropower. The Gorges Dam in China is the world's largest hydropower plant at 22.5 gigawatts (GW), producing 80 to 100 terawatt-hours per year—enough energy to supply between 70 to 80 million households.
Hydropower, whether on a large or small scale, can make a big difference in the race to find suitable energy sources to replace fossil fuels. The International Renewable Energy Agency (IRENA) has collected extensive data on how different renewable energy sources have performed worldwide, the energy they output, the cost it takes to implement these technologies, and the employment opportunities per renewable energy source. IRENA reports that 1.5 million people worked in the hydropower sector and another 290,000 in the small hydropower sector in 2017.
It is difficult to say whether one source of renewable energy alone can replace fossil fuels. It is more likely that a combination of sustainable energy sources could replace them instead. Solar power is more accessible to the average individual as it can be installed on roofs of homes with relative ease.

Hydropower is cost-effective
Hydropower has the largest electricity generation capacity compared to other renewable energy sources. For example, in Norway, 99% of the country's electricity is generated from hydropower. The Gorges Dam in China is the world's largest hydropower plant at 22.5 gigawatts (GW), producing 80 to 100 terawatt-hours per year—enough energy to supply between 70 to 80 million households.
Hydropower is also a reliable source of power as it can be used to support more intermittent energy sources like wind and solar. The majority of hydroelectric plants are storage or pumped storage facilities that store large amounts of water in reservoirs, and will almost always have stored water to pull from to generate power.
Hydropower is a viable alternative to fossil fuels, which must be burned to generate power and replenish very slowly. As hydropower relies on the water cycle, it will always be a way to generate electricity.

Hydropower is the largest electricity generator
Hydropower is a clean energy source that contributes to flood control and irrigation techniques, and can be used anywhere there is a natural flow of water. Hydroelectric plants don't use up water as they operate, making hydropower a completely renewable electricity source. As the water cycle naturally runs, hydropower will always be a viable way to generate electricity. Hydropower has the largest electricity generation capacity compared to other renewable energy sources.
Hydropower, whether on a large or small scale, can make a big difference in the race to find suitable energy sources to replace fossil fuels. Fossil fuels like coal and oil must be burned to generate power and replenish very slowly, and as such are not a long-term energy solution. The majority of hydroelectric plants are storage or pumped storage facilities that store large amounts of water in reservoirs, and will almost always have stored water to pull from to generate power.
It is difficult to say whether one source of renewable energy alone can replace fossil fuels. It is more likely that a combination of sustainable energy sources could replace them instead.
