Can energy be produced from waves?
1. **Wave Energy Potential**:
A large part of our world is covered with water, and it is possible to benefit from the waves along thousands of kilometers of coastline. According to the United Nations, up to 32 thousand TWh of energy can theoretically be produced annually from wave energy all over the world.

2. **Energy Production**:
Wave energy is obtained through wind and water movements caused by solar energy. Wave energy machines produce energy from the surface of the waves or from the pressure of the waves below the surface.
3. **Application Areas**:
- **Shoreline Applications**: Buried or fixed devices are used on the coastline.
- **Near Shore Applications**: Devices located at a water depth of 20 meters receive energy directly from where the wave breaks.
- **Offshore Applications**: Devices that benefit from high-energy waves at depth are used.
**What are the advantages?**:
- It is a renewable, sustainable and clean energy.
- No greenhouse gases are emitted as in fossil fuels.
- It is one of the pollution-free, renewable energy sources.
Although wave energy has the potential to be a solution to energy crises in the future, it has not yet become widespread. However, research and projects in this field continue.
Wave energy costs can vary depending on a number of factors. Here are some factors that affect the cost of wave energy projects.
1. **Technology Level**:
Wave energy technology is still a developing field. Newer, more efficient technologies generally cost more. However, over time, these costs may decrease.
2. **Installation Location**:
Wave power plants can be installed nearshore or offshore. Power plants built offshore may have higher costs, but they can produce more energy.
3. **Maintenance and Repair**:
Maintenance and repair of wave power plants is an important factor affecting costs. These operations may be more challenging due to sea conditions.
4. **Construction Costs**:
Construction of the power plant, offshore works and infrastructure costs may increase the total cost.
5. **Financing and Subsidies**:
It is important to obtain financing for wave energy projects. Some countries offer subsidies to encourage renewable energy projects.
6. **Energy Production**:
The amount of energy produced by wave power plants affects the return on investment time.
Power plants that produce more energy can generally be lower cost.
As a result, wave energy costs vary depending on project characteristics and local conditions. However, technological advances and increased awareness in this area may make costs more competitive in the future.
Wave energy is among the renewable energy sources and has unlimited potential. Many countries are developing wave energy technologies. Here are some countries that use wave energy.
1. **Australia**:
Australia, with its wide coastline, is utilizing its wave energy potential. Only 2% of the world's coastal waters have sufficient wave power density to extract wave energy.
2. **China**:
China is making great strides in the field of renewable energy. Wave energy projects are also developed within this framework.
3. **Denmark**:
Wave energy technologies are actively researched in Denmark.
4. **Italy**:
Italy is one of the countries that evaluates the potential of wave energy.
5. **Korea**:
South Korea is working in the field of wave energy by taking advantage of tidal currents.
6. **Portugal**:
Portugal has the world's first wave energy farm, the Aguçadoura Wave Farm.
7. **Spain**:
Spain is also among the countries developing wave energy projects.
8. **United Kingdom**:
There are active wave energy projects in England, Scotland, England and Wales.
These countries evaluate the potential of wave energy and see it as a resource that can solve energy crises in the future.
