The windier the more discount customers get on their energy bill.

This is a way the Dutch energy company Eneco wants to encourage customers to use wind power. The discount is indexed via the yearly average wind speed in the Netherlands (data sourced from Royal Dutch Bureau of Meteorology).

Also Eneco guarantees the energy comes from Dutch wind farms. If the wind farms do not provide sufficient energy due to lack of wind, this will be compensated by (clean) energy from other sources. It seems Eneco is working on placing more wind farms throughout the Netherlands to intercept this. May the wind force be with you!

Nice example of how business and renewable energy comes together.
