Landowners and communities

Wherever we work, we talk to local people about what our projects mean to them, and how they will bring tangible benefits to their communities. We do this through public meetings, information brochures, site visits, and direct contact with residents, charities and schools. And, where possible, we use local businesses and suppliers on our projects.

We also support community charity initiatives with funds from wind farm revenues.

Landowners who choose RES as a partner benefit from:

  • regular income
  • minimal disturbance to existing land activities
  • complete project management
  • greener energy
  • contributions towards reasonable legal fees
  • restoration of land at the end of a project’s lifecycle.

Our renewable energy projects fit the Japanese government’s new initiative ‘Local Creation’ through employment, as well as ‘Local Production for Local Consumption’.

Sustainability lies at
the core of our values
