Wind turbines
Wind turbines are used to harness the wind’s force, by turning aerodynamic blades that then turn a rotator to create electricity. Small-scale wind turbines are now available
to purchase for home use, these can be installed on roofs. A typical domestic system would be 2.5 to 6 kilowatts.
- Relatively minor increases in speed result in large changes in potential output.
- Knowledge of local wind speed is critical, this information can be accessed from the British Wind Energy Association website.
Cost and maintenance
Systems up to 1kw can cost up to £3,000. Turbines can have a life span of 20 years but require regular servicing.
