SDGs Addressed in the Article

1. SDG 7: Affordable and Clean Energy

   • The article’s central theme is the global shift towards renewable energy, specifically wind power, to replace traditional energy sources like coal. It highlights Germany’s “commitment to clean energy production” and a project that increases the supply of “climate-friendly electricity.”

2. SDG 9: Industry, Innovation, and Infrastructure

   • The article discusses the repowering of an “aging wind farm,” which involves dismantling old infrastructure and replacing it with “state-of-the-art new ones.” This is a clear example of upgrading and modernizing infrastructure to be more sustainable and efficient.

3. SDG 13: Climate Action

   • The move away from fossil fuels, as mentioned by the global aim to “gradually phase out coal production,” and the investment in wind power are direct measures to combat climate change. Germany’s actions are framed as part of the “global energy transition,” a key component of climate action.

4. SDG 11: Sustainable Cities and Communities

   • The project creates positive economic links with the surrounding communities. The article explicitly states that the project will provide financial benefits to “surrounding municipalities,” generating significant annual revenues and supporting local development.

Specific SDG Targets Identified

1. Target 7.2: Increase substantially the share of renewable energy in the global energy mix.

   • The article directly addresses this target by describing a project that increases a wind farm’s capacity from 9MW to 17.1MW. This action contributes to increasing the proportion of renewable energy in Germany’s energy supply.

2. Target 9.4: Upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies.

   • The repowering of the Calle wind farm is a direct implementation of this target. The process involves dismantling “aging wind turbines” and replacing them with three “state-of-the-art new ones,” which increases energy output with more efficient technology.

3. Target 13.2: Integrate climate change measures into national policies, strategies and planning.

   • The article shows this target in action by mentioning that the repowering contract was awarded through “Germany’s latest onshore wind auction held by the Federal Network Agency.” This demonstrates a formal, national-level policy mechanism designed to promote renewable energy and thus mitigate climate change.

4. Target 11.a: Support positive economic, social and environmental links between urban, peri-urban and rural areas by strengthening national and regional development planning.

   • The project supports this target through a revenue-sharing model. The article quotes an RWE executive stating, “we will pay a total of 0.3 cents per kilowatt-hour generated to the surrounding municipalities… This could generate annual revenues of up to 150,000 euros,” creating a direct economic benefit for the local region.
