Wind Turbine Information

Introduction to Wind Turbines

Wind turbines can be one of the most cost effective renewable energy technologies you can install. They produce a significant amount of electricity (in the correct location) that can be used at the property and sold back to the national grid for a profit. Wind turbines are best installed in open spaces away from nearby buildings or obstacles – If you live in the open countryside then wind turbines are ideal and are one of the most established and well known renewable technologies in the UK with the market growing rapidly over the past few years. The UK has one of the best wind resources in the world – we should make the most of it.

Benefits of Wind Turbines

  1. Sited in a good location wind turbines can produce a considerable amount of energy, bringing in significant income and having a lower payback period then other renewable technologies

  2. Wind Turbines can generate at day or at night unlike solar technologies

  3. Production of energy is well matched with use. People tend to use more electrical energy in the winter months than in the summer months. Similarly wind turbines tend to produce more energy in the winter months than in the summer.

Sample Wind Turbine System

The details below are for a sample wind turbine system. It assumes a domestic property with average electricity use and an average wind speed at the hub height of 4.5 m/s.
