Energy and climate crises are pushing insular countries, such as Antigua and Barbuda, to the frontlines. Rising fuel costs, combined with hurricanes and a tourism-dependent economy are exposing how fragile a state’s fossil-fueled energy system can become. For years, imported fossil fuels generated electricity entirely, leaving communities vulnerable to fluctuations of the global oil markets.

Now, a different future is being sketched across these islands. It is common for government plans and regional forums to center on renewable energies projects. Rather than being treated as a distant ideal, green energy is increasingly being framed as a matter of survival — economically, environmentally and socially. 

Antigua and Barbuda, as many small island developing states, is seeing the transition away from fossil fuels as the pathway to keeping the coasts protected and the economy afloat. Here is more information about the promotion of renewable energy in Antigua and Barbuda.

Antigua and Barbuda

Nestled in the eastern Caribbean’s Leeward chain, Antigua and Barbuda is a twin-islands nation that squeezes a population of nearly 95,000 onto 440 square kilometers of low coral atolls and limestone ridges — Antigua’s volcanic hills peak at just 405 meters, while Barbuda’s pancake-flat expanse is waterless and boasts pink sands.

When it comes to demography, a peculiar distribution characterizes Antigua and Barbuda: nearly all residents — 98% — crowd onto Antigua, with 60% living in St. John Parish and another 26% crammed into the capital and port city of St. John’s.

Having been a check point for the slave trade routes in the 17th century, most islanders (87% of the total) are of African descent navigate a youthful, female-skewed demographic with life expectancy hovering near 79 years.

Green Energy Targets

Antigua and Barbuda is aiming at one of the most ambitious targets in renewable energy among Small Island Developing States (SIDS), targeting 86% of electricity from local renewables by 2030 and 100% for water management essentials like desalination. This vaults it into the ninth spot among the best SIDS for expected MW capacity by 2030 — eyeing 483 MW — despite a population of less than 100,000, far outpacing per capita efforts by giants like Fiji or Cuba, home to millions of inhabitants. This green energy strategy crosses three main sectors: geothermal, wind and solar power, not all equally viable and the current share of renewable energy is only at 7%.

Although a country of very small size, geothermal power could leverage the nation’s perch on the Caribbean Plate. A 2018 pact with Polaris Energy scouts baseload potential on the territory and the government has recently expressed the intention of entering the geothermal market of St. Kitts and Nevis, a neighbor small island country, to strengthen regional energy cooperation.

At an initial look wind may seem like a source perfectly suiting an oceanic nation. However, this power proved to be a double-edged sword: trade winds whip reliably, but 2017’s Hurricane Irma — obliterating 95% of Barbuda — canceled the efforts of erecting resilient turbines, stalling ambitious sites.

It is solar power that steals the spotlight as the most reliable source of green energy, dominating almost 100% of current renewables. Bathing in year-round Caribbean sun, Antigua and Barbuda benefits from more than 4,300 hours of sunlight, making it the perfect spot for accumulating solar energy. A key feature of the sector is the shift from rooftop systems to off-grid systems. Projects like the hurricane‑resistant solar and battery plant on Barbuda are designed not just to generate clean power, but to keep the lights on after storms and also attract foreign capitals.

Changing Weather Patterns

Poverty remains a persistent challenge in Antigua and Barbuda, worsening under the strain of changing weather patterns. Those already on the margins face increasing threats from extreme weather, disrupted livelihoods and limited access to essential services such as health, transport and communications. The combined effects of hurricanes and the lingering fallout from COVID‑19 continue to erode social and economic stability.

Women are disproportionately affected, forming the majority in tourism and public sectors while shouldering household leadership. A UN Women and IISD survey urged retraining of public employees and stronger integration of gender concerns into climate policies. Many women rely on microfinance after disasters, while health risks — from waterborne diseases to mental stress — intensify vulnerabilities.

Expanding renewable energy in Antigua and Barbuda is vital to reversing these trends. Clean energy projects can lower costs, create stable jobs and strengthen climate resilience, ensuring that development benefits vulnerable groups more equitably. For instance, the International Renewable Energy Agency estimated that in a scenario where Antigua and Barbuda make it to 100% renewable energy, including the use of hydrogen and the proliferation of electric vehicles as variables, the cost of energy would decrease from USD 0.15 kWh to USD 0.09.

Why Are SIDS Obsessed With the Green Transition?

SIDS like Antigua and Barbuda, Mauritius, Nauru and others champion the green transition despite contributing a minuscule slice of global GHG emissions — less than 1% collectively, for 39 countries falling into this category.

Changing weather patterns hit them first before any other country in the world: sea-level rise erodes shorelines, hurricanes wreck homes and economies, coral die-offs cripple tourism and fish stocks.

Climate-resilient infrastructure and innovation are advancing at the national level among all SIDS. For instance, the Maldives and Tuvalu are experimenting with adaptive urban designs such as floating cities and artificial islands, adapting to rising sea levels. Collectively, SIDS are speaking out through the Alliance of Small Island States, urging stricter emissions targets and fair financial mechanisms for climate impact mitigation at the international level.
