Takeaways

• 😀 Indonesia has vast potential for utilizing ocean wave energy, which is environmentally friendly, sustainable, and inexhaustible.
• 🌊 Waves generate significant power (over Rp35,000 per mill) when they hit the coastline, and this energy is largely driven by wind, which originates from solar energy.
• ⚡ Ocean wave energy can be produced 24 hours a day, 365 days a year, making it a reliable source of energy.
• 🔋 Ocean wave energy is considered green energy, as it does not produce greenhouse gases and has minimal impact on marine ecosystems.
• 💡 Ocean wave energy is compared to hydropower, wind, and solar energy, with experts suggesting it has similar or even superior potential.
• 💸 Technological advancements and economies of scale will soon allow wave energy to be generated at similar costs to wind power (around 4.5 cents per KWh).
• 🔧 Three common wave energy technologies include: buoy-based systems, oscillating water columns, and channeling systems that focus wave energy into reservoirs.
• 🌍 Countries like the UK, Portugal, Norway, the US, China, Japan, Australia, and India are already utilizing wave energy, with many projects supported by government funding.
• 🌱 Wave energy can provide substantial power even in areas with high wind or solar intermittency, as it is available continuously without significant energy loss.
• 📉 Wave energy costs are expected to drop significantly as technology matures, making it a viable investment, especially in regions with high diesel electricity costs.

Q & A

What is wave energy and how is it generated?

Wave energy is the power generated from the movement of ocean waves. It is harnessed through various technologies that use the rise and fall of waves to generate mechanical energy, which is then converted into electricity.

How much power can wave energy generate?

Wave energy has the potential to generate significant power. For example, waves with a height of 3-4 feet hitting the shore can produce over Rp35,000 OST power per millimeter.

What are the environmental benefits of wave energy?

Wave energy is a clean, renewable source of power that does not produce greenhouse gases or harm marine ecosystems. It is a sustainable energy solution that can be used without depleting natural resources.

How does wave energy compare to other renewable energy sources like wind or solar?

Wave energy has several advantages over wind and solar. It is more stable and predictable, available 24/7, and does not depend on weather conditions like wind or the time of day like solar energy.

What types of technologies are used to harness wave energy?

There are several types of wave energy technologies, including floating systems that use hydraulic pumps, oscillating water columns that use air pressure to drive turbines, and tapered channel systems that direct water into reservoirs to generate power.

When was the concept of wave energy first introduced?

The concept of harnessing wave energy dates back to 1799, when a Parisian inventor named Montserrat, along with his son, patented the first wave energy device that used mechanical action to power machines like pumps and mills.

Which countries are currently using wave energy technology?

Countries such as Scotland, Portugal, Norway, the United States, China, Japan, Australia, and India are already using or testing wave energy technologies to generate electricity.

What are the challenges in developing wave energy technology?

The main challenge in wave energy development is technological maturity. Although the technology is progressing, it is still behind wind and solar in terms of commercial implementation. Additionally, high installation and infrastructure costs remain a barrier.

How does wave energy impact land use compared to wind energy?

Wave energy systems require much less land area compared to wind farms. While wind energy often requires large tracts of land and tall turbines, wave energy can be integrated into existing coastal infrastructure like piers or harbors, minimizing the need for new land development.

Why is wave energy considered a good investment for the future?

Wave energy offers a reliable, clean, and sustainable power source. As technology improves and costs decrease, it is expected to become increasingly competitive with other renewable energy sources. Countries with abundant coastlines, like Indonesia, can benefit significantly from investing in wave energy.
