Wind power

Wind power is generated by placing a propeller in a windy area and using the motion to power a turbine. The turbine can generate DC power to charge batteries, which can be used in DC appliances or converted to AC power for home systems. Since wind systems only generate power when there is wind available, they work better in some regions than on others. Wind can also be paired with solar to keep power generation constant on less windy days.

The ‘guru’ of small scale wind power development is Hugh Piggott, who developed a model of turbine in Scotland that is being implemented across the developing world.
