The British Virgin Islands, Columbia, Dominica, Saint Kitts & Nevis, Saint Lucia and Turks and Caicos have joined the Carbon War Room and Rocky Mountain Institute’s ‘Ten Island Renewable Challenge‘. The campaign is designed to help get the islands off fossil fuels as well as move forward with projects for schools and hospitals. The commitments were complemented by news that Virgin Limited Edition and Sir Richard Branson, who had committed Necker to the ‘Ten Island Renewable Challenge’ as a ‘demo’ island, awarded the contract to transition it on to renewables to U.S. energy firm NRG.

“What we hope to do is use Necker as a test island to show how it can be done,” said Sir Richard Branson, Founder of Virgin Group and Carbon War Room. “The only way we’re going to win this war is by creative entrepreneurship, to make the price of clean energy cheaper than that of energy from fossil fuels.”

Caribbean nations lack access to low-cost power because of the small size of their national market and an absence of standardized contracts and regional regulatory systems. In some cases, local energy suppliers, locked in for many years, currently enjoy a virtual monopoly over the system and creditworthiness is also a challenge for many nations. As a result, banks have been reticent to lend money for energy projects.

“Islands are a microcosm of larger energy systems around the world and offer an excellent test bed to demonstrate and scale innovative, clean energy solutions,” said Amory Lovins, co-founder and chief scientist of Rocky Mountain Institute. “We’re pleased to bring our decades of experience helping businesses and communities cost-effectively shift to efficiency and renewables to help island nations move beyond clean energy roadmaps to tangible, on-the-ground results.”
