It's expensive at the start, because of the dam and the turbines. It's also expensive in that it floods river valleys and damages the natural habitat. Perhaps farms and villages have to be moved.
Once it is set up, the only cost is maintenance, and it produces clean green electricity as long as the water keeps flowing. Global warming, of course, may alter the amount of water!

What are the pros and cons of gravitational energy?
Gravitational energy is a renewable energy source that is abundant and widely available. It can be harnessed in various ways, such as through hydroelectric power or gravity-based storage systems. However, gravitational energy production can be location-dependent and expensive to implement compared to other forms of renewable energy.
Do radio waves have high or low energy compared to other types of electromagnetic waves?
Radio waves have low energy compared to other types of electromagnetic waves.
Are microwaves energy efficient compared to other kitchen appliances?
Yes, microwaves are generally considered to be energy efficient compared to other kitchen appliances because they use less energy and cook food faster.
How efficient is fusion energy compared to other forms of energy production?
Fusion energy is considered to be highly efficient compared to other forms of energy production because it has the potential to generate large amounts of energy with minimal environmental impact and abundant fuel sources. However, fusion technology is still in the research and development stage, so its efficiency compared to other forms of energy production is not yet fully realized.
How is hydroelectricity gathered?
The water runs through turbines and, this mechanical energy is transfered to generator which inturn is transfered into electricity for homes, businesses, and other things that need electricity.
Hydroelectricity is an important energy resource produced in Norway Sweden and Switzerland?
Yes. Hydroelectricity is produced in other places too.
Is silver expensive?
totalySilver is very expensive compared to other elements such as iron or steel, and is the most expensive after gold.
How is hydroelectricity converted into other useful forms of energy?
it forms when electricty runs through a curcit through two wires
Is Geothermal power expensive compared to other power makers?
No.
What are the positive aspects of using hydroelectricity?
One advantage of using hydroelectric energy is that it is a renewable source of energy. Other positive aspects include a guarantee in energy and price stability as well as its feasibility in utilizing other renewable sources.
Is fleece expensive compared to other types of fabric?
Fleece is generally considered to be an affordable fabric compared to other types of fabric.
Are Christmas flights typically expensive compared to other times of the year?
Yes, Christmas flights are typically more expensive compared to other times of the year due to high demand and limited availability.
Why is biomass so expensive?
Biomass as a product is not as expensive as many may assume. It is however a common believe that the process of making biomass is rather costly as compared to other sources of energy and this directly impacts on the cost of biomass as a finished product.
How does heating with electricity compare to other heating methods in terms of efficiency and cost?
Heating with electricity is generally less efficient and more expensive compared to other heating methods, such as natural gas or propane. This is because electricity is often more expensive and less energy-efficient than other fuel sources.
Fuels such as the wind and sun that can generate power without being used up?
Wind energy and solar energy are called renewable energy sources. Other renewable energy sources include hydroelectricity (generated by water movement) and geothermal energy.
What other source of energy can you use instead of hydroelectricity?
Electicity from coal, oil, natural gas, nuclear, biomass, wind, solar, tidal sources.
What are the pros and cons of gravitational energy?
Gravitational energy is a renewable energy source that is abundant and widely available. It can be harnessed in various ways, such as through hydroelectric power or gravity-based storage systems. However, gravitational energy production can be location-dependent and expensive to implement compared to other forms of renewable energy.
