The belief that green electricity requires an excessive amount of land is a common misconception. In reality, renewable energy sources - particularly solar and wind - can be installed in a way that maximises land efficiency and even complements land use.

Solar farms, for example, don’t necessarily require large, dedicated areas. They can be integrated into existing structures, such as rooftops, parking lots, and along the sides of roads. This approach not only saves space but also converts otherwise unused surfaces into energy-generating assets.

Moreover, the concept of dual-use land use (also referred to as agrivoltaics), where solar panels are installed on agricultural land, demonstrates the efficient use of land for dual purposes. This practice allows for both electricity generation and agriculture practices to coexist. Studies have shown that this can lead to higher crop yields and reduced water consumption, making it a mutually beneficial relationship.

Wind farms are another example of efficient land use. The actual footprint of a wind turbine is relatively small, leaving the surrounding land available for other uses, such as farming. Additionally, offshore wind developments are gaining in popularity - by installing wind turbines offshore, you eliminate land use.

One more point is that the land footprint of renewable energy sources should be compared to the full lifecycle land impacts of fossil fuels. Renewable energy installations generally have a lower total land footprint when accounting for extraction, transportation, and processing activities associated with fossil fuels.

👉 Through efficient land use, innovative dual-use practices, and the development of offshore projects, green electricity can be a land-efficient energy solution.
