Read about how the centralized microgrid style system used by many island nations can be a resilient path forward to energy equality and efficiency in urban areas experiencing power outages, and the effects of climate change.
According to the World Economic Forum's Global Risks Report 2024, extreme weather events are expected to be among the most severe global risks over the next 10 years. The report highlights that extreme weather events are anticipated to be the top risk in 13 countries over the short term (two years) and remain one of the top three risks globally through 2034.
The term 'Island Grids' originated from a breakout workshop at the Blue Planet Alliance Island Nation Renewable Energy Fellowship event in May 2024 in Oahu, Hawaii. It describes how island nations are utilizing microgrids at a higher level through the implementation of residential and community-based renewable energy systems, in addition to national renewable energy plans, and at a faster pace.
While the United Nations goal is to reach net zero emissions by 2050, Blue Planet Alliance has set their sights on 2045 as island nations prioritize climate change resiliency and the effects of increasing weather patterns.
What Is the Island Microgrid Method?
Microgrids are localized energy systems capable of operating independently or in conjunction with the traditional grid and have emerged as a viable solution to address the unique energy challenges faced by many island nations.
These challenges often include geographical isolation, high energy costs, and vulnerability to natural disasters. By harnessing renewable energy sources such as solar, wind, and hydro, these microgrids not only provide a sustainable energy supply but also enhance energy security and reliability.
In urban settings, the adoption of a centralized microgrid system can lead to significant improvements in energy equality, especially in densely populated areas where energy demand and disparities are high.
By creating a more localized energy production and distribution model, urban centers can ensure that all residents, regardless of socioeconomic status, have access to affordable and reliable energy.
The increasing rate of self-reliant home and residential microgrid units and their associated storage capacities, are closely linked to higher-than-average socioeconomic demographics.
This correlation suggests that households with greater financial resources are more likely to microgrid energy solutions. There remains a significant barrier to entry for many residents, particularly those from lower socioeconomic backgrounds.
How Are Microgrids Resilient to Climate Change?
Microgrids can be designed to integrate energy storage solutions, allowing for the management of energy supply and demand effectively, even during peak usage times.
The implementation of centralized microgrids can stimulate economic growth in urban areas and lessen the burden on the main macro grid system operators as they are dismantled or repaired.
Microgrids are resilient to climate change because they are designed to function independently regardless of the larger grid, allowing them to maintain energy distribution even when external systems are compromised.
This autonomy is crucial during severe weather conditions such as hurricanes, blizzards, or wildfires, where traditional power infrastructure may be severely damaged or rendered inoperative.
Microgrids can incorporate a diverse array of energy sources, including renewable options such as solar, wind, and biomass, which are often more sustainable and less susceptible to the fluctuations caused by climate change.
By relying on locally generated power, microgrids reduce the dependency on long-distance energy transmission, which can be vulnerable to disruptions caused by extreme weather.
This localized approach not only enhances energy security but also contributes to a reduction in greenhouse gas emissions, aligning with global efforts to combat climate change.
With the reduction of distribution lines and infrastructure in transporting energy long distances through pipelines and shipping, the microgrid method in urban areas also eliminates the risks associated with the macro grid model.
The modular design of microgrids allows for quick scalability and adaptability. Communities can enhance their energy resilience by integrating energy storage systems, such as batteries, which store excess energy generated during peak production times for use during periods of high demand or supply shortages.
This capability ensures that even during prolonged outages, critical facilities—such as hospitals, emergency response centers, and shelters—can maintain operations, thereby protecting public safety and welfare.
Microgrids can be deployed in vulnerable regions that are frequently impacted by climate-related disruptions and demonstrate resilience in the face of climate change including increased extreme weather events, grid vulnerability, all with the projection of increased disruptions.
By leveraging local resources, enhancing access to renewable energy, and fostering economic development, these systems can pave the way for a new standard in sustainable living and city planning.
It is no wonder why island nations are leading the way towards 100% renewable energy by 2050 by harnessing the powers of microgrid systems. The centralized microgrid systems used by many island nations present a practical model for urban areas striving for energy equality and efficiency.
This approach aligns closely with the United Nations Sustainable Development Goal 7 (SDG 7): Affordable and Clean Energy. SDG 7 aims to ensure access to affordable, reliable, sustainable, and modern energy for all.
This goal recognizes that energy is a crucial component for the development and enjoyment of life, including health, education, and economic growth.
Achieving energy equality is essential for eradicating poverty and fostering sustainable development, as it enables communities to thrive by providing the necessary resources for daily activities and long-term planning.
SDG 7 emphasizes the importance of increasing the share of renewable energy in the global energy mix, which is vital for combating climate change and reducing greenhouse gas emissions.
The transition to clean energy sources such as solar, wind, and hydroelectric power not only contributes to environmental sustainability but also promotes energy security by diversifying energy supply and reducing dependency on fossil fuels.
In addition to promoting renewable energy and efficiency, SDG 7 highlights the need to improve energy infrastructure and technology, particularly in developing regions where access to energy remains a challenge.
This includes investing in energy systems that are resilient and adaptable to the changing climate, ensuring that all populations, especially marginalized and vulnerable groups, can access the energy they need. By addressing these disparities, SDG 7 aims to create a more equitable energy landscape that supports social inclusion and economic development.
Achieving energy equality also involves fostering international cooperation and partnerships, as many countries may lack the resources or technology to transition to clean energy. SDG 7 serves as a call to action for governments, businesses, and civil society to collaborate in creating a world where clean energy is accessible to all, thereby laying the groundwork for a sustainable future.
Some of the highest-level activities and decisions that shape the framework for future outcomes in renewable energy development occur at the annual United Nations COP event, which was recently in Baku, Azerbaijan this November 2024 (COP29).
Support for residents and communities is essential in facilitating a renewable transition, in particular the least developed countries. Many residents may lack the resources to navigate available programs designed to promote the adoption of microgrid technology and energy storage systems.
Community outreach and educational initiatives can help demystify the application processes, provide guidance on how to access available resources, and assist residents in making informed decisions about energy solutions that best fit their needs and circumstances.
