Cuba's once thriving sugar industry has begun opening up to foreign investment for the first time since the revolution.

British firm Havana Energy has become the first to sign a joint venture and will build a green power plant at one of the country's biggest sugar mills.

The project will also attempt to harvest a much-hated weed to use as biofuel.
