Wind power

Communal schemes

Practical Action is experimenting with three different schemes for generating electricity through wind power.


The first involves using a small wind-powered system to provide electricity for a single house as in the Weerasuriya familys home.

The second involves a group of six generators, which charge up a number of batteries. Six houses are then connected to these batteries.

Wind turbine which supplies power to 22 people in all

The third arrangement involves having one large wind machine and storage system for a whole village (in the current experiment this is 18 houses). Deep cycle batteries are used, which can provide electricity for a longer period without recharging. The generator, batteries and inverter are all imported. A diesel generator supplements the wind-powered generator when there is not enough wind. To make this more sustainable, a biogas system (using animal and agricultural waste) generates methane for the diesel engine, reducing the amount of diesel used. The slurry from methane production is used as a soil conditioner.

This communal scheme is managed by a Womens Society in the community. The women are responsible for ensuring that the equipment is maintained and the electricity is shared out fairly.
