The Land Use Dilemma: Golf Courses vs. Renewable Energy
A recent study has unveiled a surprising comparison: golf courses across the world occupy more land than solar or wind energy plants. The research paper, titled “Countries across the world use more land for golf courses than wind or solar energy,” highlights a significant opportunity for renewable energy expansion. The 10 countries with the highest number of golf courses could potentially install up to 842 GW of utility-scale solar or 659 GW of wind capacity on the land currently dedicated to golf courses.
The Potential of Underutilized Land
The study, conducted by researchers at Forschungszentrum Jülich, reveals that the land currently used for golf courses in these 10 countries could accommodate between 281 GW and 842 GW of utility-scale solar energy. This figure is particularly striking when compared to the current cumulative solar capacity of 646 GW installed in these countries.
The researchers utilized the OpenStreetMap database to identify 38,400 golf courses worldwide, with 80% of these located in just 10 countries. The United States leads the list with over 16,000 golf courses, followed by the United Kingdom (~3,100) and Japan (~2,700). Canada, Australia, Germany, South Korea, France, China, and Sweden round out the top 10.
Real-Life Example: United States
In the United States, the land area dedicated to golf courses is substantial. If just 25% of this land were repurposed for solar energy, it could generate a significant amount of clean energy. This highlights the potential for renewable energy expansion in similarly large and underutilized areas.
The Debate on Land Use
“In light of the ongoing debates about land use for renewables, it is crucial to consider how we allocate land overall – especially when significant space is dedicated to activities that benefit only a limited segment of the population,” said Jann Weinand of the German research institute Forschungszentrum Jülich. The study aims to spark a conversation about the efficient use of land for renewable energy rather than advocating for the direct conversion of golf courses.
Did You Know?
The energy density of fossil fuels is significantly higher than that of renewable energy storage solutions. Natural gas, for example, has an energy density of 53.1 MJ/kg, compared to just 0.504 MJ/kg for lithium-ion batteries, which are commonly used to store renewable energy.
The Energy Density Dilemma
Fossil fuels are more energy-dense than renewable energy sources. Natural gas boasts the highest energy density at 53.1 MJ/kg, followed by gasoline at 45.8 MJ/kg and coal at 30.2 MJ/kg. In contrast, lithium-ion batteries, one of the most effective ways to store renewable energy, have an energy density of only 0.504 MJ/kg. This disparity underscores the challenges in transitioning to renewable energy sources.
The Future of Renewable Energy
The study highlights the vast potential for renewable energy in underutilized areas. While the direct conversion of golf courses is not the goal, the research encourages policymakers and energy planners to consider alternative land uses that could benefit a broader segment of the population.
Pro Tip
When planning for renewable energy projects, consider the land use efficiency of different energy sources. Utilizing underutilized land, such as golf courses, can maximize the potential for renewable energy generation.
