How Renewable Energy Can Restore Our Land: World Environment Day 2024

As we approach World Environment Day 2024, focusing on renewable energy as a catalyst for land restoration and environmental sustainability has never been more critical. Renewable energy can catalyse land restoration and promote environmental sustainability.

It is a cornerstone in the fight against land degradation and desertification, offering sustainable solutions to restore ecosystems and enhance resilience against climate change. 

Renewable energy installations, including solar panels and wind turbines, contributing to drought resilience and environmental sustainability for world environment day

Harnessing solar, wind, and biomass energy power, previously barren lands can be transformed into productive landscapes. For instance, solar farms can be established on barren lands, providing clean energy while promoting vegetation growth under the solar panels. 

With global capacity reaching 2,800 GW in 2023, the potential for positive impact is immense. Investments in renewable energy projects range from £500,000 to £5 million. This theme highlights the urgent need to address land degradation. It affects up to 40% of the planet's land and threatens half the global GDP.

This dual-use approach not only generates electricity but also helps in restoring soil health and biodiversity. 

Renewable Energy and Land Restoration

Integrating renewable energy projects with land restoration initiatives offers a promising approach to revitalising degraded areas and combating desertification. 

Renewable energy sources can significantly benefit land restoration projects such as reforestation and soil regeneration. In regions where water scarcity poses a significant challenge, solar-powered water pumps provide a sustainable solution for irrigation. About 2 million of these pumps are installed worldwide, supporting the growth of trees and crops.

For instance, the EcoFuture project in the Jordan Valley aims to develop a climate-change adaptation program. This program includes renewable energy solutions such as solar desalination and smart agriculture in acclimatised greenhouses. This project addresses water scarcity and promotes sustainable agricultural practices, enhancing soil fertility and reducing land degradation.

Wind power and forest restoration can be synergistic. Wind turbines, often placed on large plots of land, can coexist with reforestation projects. This dual use of land helps generate clean energy while restoring degraded ecosystems. For example, reforestation can improve soil conservation, water retention, and biodiversity, creating new habitats for wildlife and providing sustainable livelihoods for local communities. 

Bioenergy projects, like cultivating energy crops on marginal lands, can improve soil fertility and offer sustainable livelihoods to local communities. These initiatives are not only environmentally beneficial but also economically viable, with investments ranging from £500,000 to £5 million, depending on the scale and scope of the project.

The EPA's RE-Powering America's Land Initiative encourages renewable energy development on contaminated lands, landfills, and mine sites. Often unsuitable for other uses, these sites can be repurposed for solar energy projects, turning previously degraded land into productive areas. This approach generates clean energy and revitalises the land, reducing environmental impacts and supporting local economies.

These initiatives highlight the synergy between renewable energy and land restoration, creating a sustainable and resilient environment.

Statistical Impact

To illustrate the impact of renewable energy on land restoration, desertification, and drought resilience, consider the following hypothetical data:

  • Land Restored: Renewable energy projects have restored approximately 10,000 hectares of degraded land.
  • Water Usage Reduction: Implementing solar and wind energy has led to a 30% reduction in water usage.
  • Agricultural Yield Increase: Integrating renewable energy with sustainable agricultural practices has resulted in a 15% increase in agricultural yield.
  • Soil Erosion Reduction: The presence of renewable energy installations has reduced soil erosion by 25%.
  • Groundwater Level Increase: Renewable energy projects have contributed to a 10% increase in groundwater levels.
  • Economic Benefit: Renewable energy projects generate approximately £50 million in economic benefits each year.
  • Carbon Sequestration: Renewable energy projects have sequestered around 100,000 tons of CO2 annually.

Combating Desertification with Renewable Energy

Desertification poses a severe threat to fertile lands, but renewable energy offers viable strategies for prevention and reversal. Approximately 25% of global land is currently degraded, which requires innovative solutions. Solar panel power, in particular, provides a viable solution for arid and semi-arid areas.  

Under a high emissions scenario, more than 70% of copper, cobalt, and lithium production might experience considerable or increased drought risk by 2050. These minerals are critical to the clean energy transition. It's up from less than 10% today.

Integrating renewable energy with sustainable agricultural practices, such as agroforestry and precise irrigation, can improve soil quality and prevent land degradation. 

Moreover, wind-powered desalination plants convert seawater into fresh water. Bioenergy projects that produce biochar to improve soil fertility are additional strategies that leverage renewable energy to combat desertification. Currently, 743 GW of wind energy capacity is installed worldwide.

These practices improve soil health and water retention and increase crop yields, providing economic benefits to local farmers.

Enhancing Drought Resilience through Renewable Energy

With the UK's renewable energy share reaching 47% of electricity generation in 2023, the commitment to renewable solutions is evident. Solar-powered desalination plants, which account for 60% of new plants, provide essential fresh water, reducing the impact of drought and supporting sustainable water management practices.

Renewable energy technologies such as solar-powered water pumps and desalination plants significantly enhance drought resilience. 

For example, in California, deploying solar and wind energy has helped compensate for electricity deficits caused by reduced hydropower generation during droughts. This shift ensures a stable energy supply and conserves water resources for agricultural use. 

The same goes for the UK, where solar-powered desalination plants provide a sustainable solution to water scarcity in coastal regions. Additionally, solar-powered water pumps can be used in rural areas to extract groundwater efficiently, supporting agricultural activities and reducing the impact of drought on food production.

Moreover, Desalination plants powered by renewable energy provide an alternative source of fresh water, essential for drought-prone regions. These plants can significantly reduce the pressure on freshwater resources by converting seawater into potable water. With over 16,000 global desalination plants, solar and wind energy can power these processes, making them more sustainable and cost-effective in the long run.
