Renewables Benefit Island Tourism, Says New IRENA Report

A new report by the International Renewable Energy Agency (IRENA) on how how renewables can benefit island  tourism.

The study, Renewable Energy Opportunities for Island Tourism, examines four renewable energy technologies:

  • solar water heating,
  • solar air conditioning,
  • seawater air conditioning, and
  • solar PV systems.

Tourism often drives island economies, but the need to import costly petroleum products, notably diesel, can reduce financial gains. Energy supply in the form of air conditioning, water heating, lighting, and other hotel needs is a critically important component of the resort experience. Both the environmental impacts of fossil-fuel use and the volatility of oil prices mean that tourism-based economies must sometimes operate on a financial roller-coaster.

Chart from IRENA's renewables and island tourism reportRenewable energy technologies can strengthen sustainable development and marketing strategies in the island tourism sector, reduce its operating costs, and lower its environmental footprint. The latter factor benefits both island residents and the growing number of “ecotourists” who willingly pay a little extra to enjoy the more sustainable lifestyle.

IRENA presents case studies of four resorts and hotels:

  • Turtle Beach Resort in Barbados saved $1.5 million over a 16-year period after installing a solar water heating system.
  • Turtle Island Resort in Fiji is saving $250,000 annually with its PV system.
  • Intercontinental Bora Bora Resort & Thalassso Spa in French Polynesia retrieves $720,000 in annual savings thanks to a seawater air conditioning system.
  • Rethymno Village Hotel in Crete saves 70,000 kilowatt hours a year for cooling with its solar air conditioning system.

The analysis and the four case studies show that impressive benefits can accrue from installing renewable energy systems for island tourism.

IRENA’s study concludes with the following:

“This report shows that renewable energy technologies (RETs) represent an economically attractive option for the island tourism sector. The cost of air conditioning and water heating from RETs is considerably lower than using electricity generated from diesel for the same service, while solar PV can generate electricity more cheaply than utility tariffs or self-generation from diesel in most islands.”

As well as increasing environmental benefits and increasing self-sufficiency, island renewables can reduce uncertainties and actually provide a marketing advantage.
