Wind Energy Direct – Frequently Asked Questions
If you have a question that’s not answered here, please contact us »
Wind energy is a converted form of solar energy. As the sun heats air, some of it gets hotter than the rest (depending on terrain, season and time of day). The hotter air rises up and cool air replaces it. The result is wind.
The movements in the air create kinetic energy, which can be converted into other energy forms – like mechanical force (turning the blades) or electricity.
A wind turbine works by harnessing kinetic energy and transforming it, via a motor inside the shaft, into conventional electrical energy. Unlike fossil fuel generators, wind power generators do not release any harmful gases into the atmosphere.
Wind turbines come in two basic models: vertical-axis turbines, and horizontal-axis turbines. Horizontal-axis (propeller) turbines are the most commonly used.
The direction, speed and force of wind changes all the time, even within a short radius of space. That’s why you may sometimes see a wind farm with only a few spinning turbines.
The towers are mostly tubular and made of steel, usually painted light grey. Some towers are made of concrete. The blades are made of glass fiber reinforced polyester or wood – epoxy. They are light grey because this is the colour most inconspicuous under most lighting conditions. Most turbines are approximately 80 metres in height with a rotor diameter of between 60 – 80 metres.
A wind turbine typically lasts between 20-25 years. During this time, like any machinery, some parts may need replacing.
Our feasibility study is an extensive review of the wind energy resources on your premises. Using state-of-the-art equipment, our engineers are able to determine when and how much wind blows in your area. This means you can predict with confidence the amount of renewable energy that will replace your traditional fossil fuelled energy.
The turbine remains at rest. But it’s very rare; each turbine is erected more than 64 metres above ground, and your site will have been tested to ensure adequate wind resources. When we test your site for feasibility, we investigate the long-term wind patterns to ensure that you’ll be able to rely on the turbine to make a saving.
They’re nothing like the turbines that were first unveiled in the 1980s! In fact, modern wind turbines are designed to harness as much energy as possible – which includes sound energy. So the sound from your wind turbine will be comparable to the normal level of noise in a typical residential area. We work with your local planning office to make sure that sound generation is kept to a minimum.
It’s the shadow cast by the blades of a wind turbine. Modern turbines are situated very carefully to make sure that this type of shadow will not affect anyone in a nearby residence or office.
Wind Energy Direct partners with world-renowned turbine manufacturers for the construction of our turbines. We retain an ownership share, and manage the construction and engineering of these projects. It’s in our interest to ensure that every single turbine we build is top of its class.
Of course you could, but that means shouldering the risk yourself. WED is a specialist in renewable energy. We will assess, plan and install a wind turbine on your site, and will then supply electricity to you at a significantly discounted rate. We give you free advice on the suitability of your site before we begin.
Not only are the prices of energy from your own turbine at a significantly discounted rate, your brand will profit, too. Installing a renewable energy source on your premises makes a powerful statement about the sustainability and future-vision of your business.
Wind Energy Direct is a wind energy development company with offices in Limerick. Wind Energy Direct specialises in installing wind turbines on our customers industrial and green field sites throughout Ireland.
