Is hydropower the future?
Views: 79Introduction
Hydropower is a mature technology that’s been around for more than 100 years, but it still plays an important role in the world’s energy supply. In fact, hydropower accounts for about 17% of the electricity generated globally. It also helps to provide electricity without releasing greenhouse gases or other pollutants into the air—which makes it an attractive option for many countries looking to reduce their carbon footprint and meet their climate goals in a cost-effective way.
Hydroelectric power plants convert the energy in falling water into electrical energy.
Hydroelectric power plants convert the energy in falling water into electrical energy. Water is directed through a dam and down a penstock, or pipe, to drive a turbine connected to an electric generator. The force of the water turns the turbine, which is connected to a generator that produces electricity.
Hydropower has advantages and disadvantages.
One of the biggest advantages of hydropower is that it’s a mature technology. Due to this, it can be built quickly and at a very large scale. Hydropower facilities can be built in almost any country, so there are few barriers to entry for developers (excepting some restrictions on where dams can be built). The power output from existing hydropower plants is also reliable and predictable—you’ll get the same amount every day, as long as there’s enough water in the reservoir behind your dam. This makes it ideal for meeting peak demand during hot summer days when people want air conditioning or heating their homes.
Another advantage of hydroelectric power generation over other renewable technologies is that it can be used to store excess electricity for later use. When demand peaks outstrips supply during certain times of year (the winter), you can run your turbines faster to generate more electricity while less water passes through them—and then store that extra energy until springtime when demand starts rising again!
Hydropower is important to our global electricity supply, but other renewable sources of energy like wind and solar energy are growing rapidly.
You might think that hydropower is the most important form of renewable energy, but it actually makes up just 17% of the world’s total renewable capacity. Wind and solar are growing rapidly, and they could make up as much as 30% of our energy needs by 2030.
Hydropower is an important source, but if we want all sources of renewable energy to grow faster than fossil fuels (fossil fuels include coal and oil), then we need to focus on other types like wind and solar power.
Is hydropower renewable?
Is hydropower renewable? The answer is yes, it is.
Hydropower is a mature technology that has been around for decades. The United States has about 30,000 dams (more than any other country in the world), with over 18,000 of those being large dams (> 15 MW). Hydropower generates about 7% of the world’s electricity and 17% in the US. It’s also one of the most reliable sources of energy: rivers don’t dry up; they flow consistently year-round. And because it doesn’t produce greenhouse gases like coal plants or nuclear reactors do, it’s carbon neutral — unlike solar panels or wind turbines (which have to be manufactured and shipped across oceans).
All things considered: hydropower is renewable!

Hydropower doesn’t require massive amounts of time to build and install, like nuclear or wind power plants do. Hydropower plants can be built within only a few years of planning, which makes it an attractive option for many countries considering their future energy needs.
Countries are looking to hydropower for more carbon-neutral generation capacity.
Countries are looking to hydropower for more carbon-neutral generation capacity. Hydropower is carbon-neutral, which means that the emissions it produces when generated are roughly equal to those absorbed by plant life as they grow and decay. This makes it an attractive source of energy as countries look to meet their climate change goals. And because it’s a renewable resource, if there’s enough water in a river or lake, then you can use hydropower in perpetuity (albeit with some changes over time).
Hydropower also helps complement other sources of renewable energy like wind and solar power. For example, when there’s no sun or wind available, hydroelectric plants can provide baseload power—meaning they’ll run all day long without interruption.
Energy from hydropower is predictable, unlike from wind and solar energy.
Hydropower is a reliable source of electricity, unlike wind and solar energy. When you plug in your phone charger at night, you can be sure that there’s enough energy coming from the electrical grid to power it. This is because hydroelectric plants are able to generate electricity 24/7—they never run out of water or stop producing energy due to weather conditions like clouds passing over their location.
Hydroelectric power production can be used to store excess electricity for later use.
Hydroelectric power can be used to store excess electricity. When electricity demand peaks, hydroelectricity can be used to lower the price of electricity. For example, if there is a lot of wind generation and not enough demand to use it at that time, it may be cheaper for companies to purchase hydroelectricity instead of using fossil fuels or other forms of energy. Hydroelectric power plants usually provide a steady base load for an electric grid because they do not rely on wind or sun (as does solar PV). They are often located near cities; therefore they are able to meet peak demands during daytime hours when most people are awake and working.
Hydroelectricity will continue to play an important role in the world’s power supply.
Hydroelectricity will continue to play an important role in the world’s power supply. It’s reliable, predictable and can be built quickly at a very large scale. The technology has matured since it was first used over 100 years ago and is now considered a mature energy source that’s efficient and cost-effective.
In addition to providing clean energy, hydroelectricity can also be used as a way to store excess electricity from renewable sources such as wind or solar power plants.
Conclusion
The world needs clean, reliable sources of electricity that can provide power when wind and solar energy are unavailable. Hydropower is a proven technology that has been used for decades to generate electricity and is still in use today. The problem with this method is that it may not be environmentally friendly because of its negative effects on local ecosystems like river erosion or reduced biodiversity due to dam construction. However, the overall impact of hydroelectricity on global climate change may be lower than other sources like fossil fuels if we consider the amount of carbon dioxide stored by forests around dams due to their deforestation-free construction process.
