The island is accessed from the mainland by regular ferries from Östanå as well as by boat from central Stockholm.

Ljusterö is the site of a proposed project to install a large number of wind turbines to generate renewable energy.

The project proposes 23 turbines, each with two megawatts electrical power output.

The project has been heavily criticised by a large number of summer residents as well as permanent residents for affecting the archipelago's environment and views too much, making the island "look like an industrial power plant".

Several other negative effects has been stated, such as generation of low frequency noise, drop of real estate values etc.
