As of 2003, no renewable energy installations were operating in the country.Solar energyAntigua and Barbuda are reported to have one of the best potentials for solar energy development in the Caribbean. Solar water heaters have already achieved some commercial success in the country. Lack of awareness has been blamed for the lack of further uptake of the technology.Wind energyIn the past, Antigua produced sugar by wind power — indicating a good wind resource. However, recent attempts to use wind energy for electricity generation have proved less successful due to high up-front costs, lack of data on wind measurements, and low technical capacity.A study sponsored by APUA (Wind Energy Survey Antigua and Barbuda, Energy Engineering Corporation, November 2008) indicated that in Barbuda, the “Highlands” area offers the most promising wind farm site. At 33 meters above sea level, this plateau of 38 km2 can support 400 MW of wind turbines, generating 900 GWh per year, with little visual impact because the area is five kilometres from population centres.Biomass/BiofuelsLittle research has been done into the potential for these resources in the country; however, sugar production in the country indicates the potential for exploitation of bagasse for heat and co-generation purposes.Geothermal/HydropowerNo assessment into the potential for these resources in the country has been conducted. The highest point in the country stands at 399m above sea level, indicating a possible potential for small hydropower.
