The wind is an alternative energy that is constantly being renewed naturally. Reporting to National Geographic, winds are formed from the sun that does not heat the earth’s surface evenly. Thus, hot air rises, and cold air enters under it to replace the rising air. It is the change of air that results in wind. Simply put, the wind will continue to exist as long as the sun shines on the earth. This makes the wind a free item that will stay supplied.
Wind energy is usually generated from turbines and windmills built in areas rich in wind sources and then converted into electricity. Wind power is converted into electricity through electricity generators. The potential of wind power as an alternative energy source is very open and possible to meet 12% of the world’s energy needs in 2020. Meanwhile, good use of wind power can also expand employment to millions of people and can especially reduce Co2 pollution to thousands of millions of tons.

Wind power is also easy to get for free because nature provides this power continuously abundantly and without stopping, but unfortunately, the use of wind power is still very minimal due to various obstacles that come its way, especially for developing countries, which are minimal for the development of alternative technologies such as wind power.
Germany is the country with the largest utilization of wind power in the world and whose wind energy utilization capacity reaches above 30% of the total wind energy utilization in the world. As a maritime country with many Indonesian islands, it is more potential to make wind as a substitute energy because large winds are found in many coastal and marine areas. As a country with many islands, Indonesia has the potential that can be placed on various islands, both inhabited and deserted.
But what are the advantages and challenges of wind energy?
Wind energy is one of the fastest-growing sources of energy in the world due to its many benefits. Wind power also presents inherent challenges in some parts of the world, which research and development (R&D) projects around the world are tackling.

- Wind energy is profitable in many regions. In other respects, wind power must compete with other energy sources, but global R&D efforts are working to find solutions to reduce the Levelized cost of electricity (LCOE) for onshore wind and offshore.
- Another advantage of wind energy is that it is a domestic energy source that uses unlimited local resources. However, viable sites for some wind farms are located in remote areas, which will present challenges for construction and transmission logistics. Technological breakthroughs such as split blades and modular construction help overcome these challenges.
- Another advantage of wind energy is that it is a sustainable source of energy because the operation of wind turbines does not directly emit carbon dioxide or greenhouse gases, which helps countries meet their emission reduction targets and tackle climate change. Wind energy is abundant and readily available, and harvesting its energy will not deplete our precious natural resources. An environmental benefit of wind energy is its ability to offset the adverse effects of climate change. The Global Wind Outlook projects that wind energy will offset 2.5 billion tonnes of carbon emissions per year by 2030.
The wind is a clean, free, and readily available renewable energy source. Each day, around the world, wind turbines capture wind power and convert it to electricity. Wind power generation plays an increasingly important role in how we power our world – in a clean, sustainable manner.
