Green wind power A healthy (outdoor creatures) way to meet the world’s energy needs
No commentsBy Gen Wright
The Green wind power has been harnessed since past two decades, and the advantages of the green wind power have caught the eyes of the big power companies to invest on big wind turbines and setting up massive wind farms.
Initially, the wind farms were limited to power generation only for residential purposes such as generating power for farm machines and houses. However, over time the application of this form of power in commercial terms grew popular.
As per the recent facts and figures, over 600 wind turbines have been incorporated for the generation of green wind power in the state of Iowa. More and more countries are entering into the production of green wind power with every single passing day.
With the technological developments the size of turbines is increasing, and so is the production in the wind farms. Consequently, turbines even as high as 240 feet tall have been incorporated into the production of green wind power. Moreover, as many as 150 turbines have been made use of, on a single land-piece. Hawaii boasts of the highest wind turbine ever built, which stands as tall as 20 stories high, with massive 100yard-blades accounting to about size of a soccer field.
Considering the classification of wind turbines, mainly they come in two types namely the horizontal axis and vertical axis turbines. The horizontal one is popular than the vertical ones, since the horizontal ones are equipped with rotor blades towards the topmost part of the tower. On the other hand, the vertical axis turbines come with vertical sails, which operate similar to the horizontal ones. While the sail traps the wind energy, this energy in turn is harnessed to rotate the shaft of turbine that ultimately powers a dynamo, thus producing green power.
There are several specialized turbines built for operating off the shore, as well as on land. Denmark has been reported to make extensive use of horizontal axis turbines to generate green power. Looking into technical details, people often get confused with the windmills and turbines. These green wind turbines surely work similar to the windmills, but they generate electricity, while the windmills are used for grinding grains and performing similar tasks.
Moreover, the green wind power turbines work just in the reverse way as that of a normal fan, which makes use of the blades and electricity to generate wind. On the contrary, wind turbines convert the wind electricity into electrical power and helps in generation of large amounts of electricity. This form of electricity is eco-friendly, and doesn’t exhaust the conventional resources of the planet, and is also available even for commercial purposes.
Lastly, looking at the specs of the wind turbines, they’ve been built with perfection to the utility scale, and are capable of producing electricity anywhere from 50 KW up to a whopping 750 kilowatts of power. Therefore, the usage of green wind power must be promoted for environmental benefits, while they also offer a cheaper alternative to conventional sources of energy as well.

Make your home office green
By Annie Deakin
Electronic equipment
Maximise natural lighting by using the sun’s energy to brighten your office. You don’t need any building permissions to install this Solar Mate panel (239.99) from Nigel’s Eco Store. Even in dreary old Blighty, it will store between 8-11 hours of light for its bulb. Screensavers save the screen, not energy, so switch off your monitor (which uses twice the energy of your PC) altogether when you go for lunch, as well as the PC itself. British Eco make it easy with these Bye bye standby plugs (19.99 for intrdouctory pack), which allow you to control your equipment wirelessly from up to 30 metres away. Handy for those forgetful days.
Make business calls on this Siemens Gigaset digital cordless phone (49.95) from John Lewis, which claims to use up to 60% less energy than regular cordless phones. For more ideas, read the Eco-design handbook for homes and offices (16.95) from the Design Museum shop and get up to speed with what else you can do.
Junk Mail
Almost 50% of all catalogues sent by post are never opened, yet nearly 62 million trees and 28 billion gallons of water are used every year to produce them. Get yourself removed from junk-mailing lists by registering with the Mailing Preference Service.
Printing and paper
Print only the information you really need from a document, and also print double-sided, using the smallest font you can and switching your printer to draft output to save ink. Make sure you recycle your print cartridges using one of the many post-it-back schemes, and use chlorine-free recycled paper. For every tonne of paper that is recycled, we save 17 trees, 42,000 kilowatts of electricity, 26,000 litres of water and 27 kilograms of air pollutants. Do your filing and store documents in these award-winning recycled lever arch files (2.45 each) from the Natural Collection.
Meetings and communication
Install video-conferencing facilities (easily achieved via the use of a webcam), so you can keep in touch with clients and the office without having to travel.
Electrical efficiency
Use energy-efficient, compact fluorescent bulbs, which use 75 per cent less energy and last 10 times longer than traditional bulbs. For desk lamps, choose miniature compact fluorescent lightbulbs (CFLs) or light-emitting diodes (LEDs). This Ocean energy saving lamp (95) from Hidden Art not only looks stylish enough to impress clients. Choosing electrical equipment with an energy-star label could cut your electricity bill by up to 80 per cent. The Energy Star logo means that the energy consumption of an appliance is below an agreed level in stand-by mode.
Don’t leave chargers running
Switch off the charger for your mobile phone, batteries, camera and other equipment when you’ve finished charging. If you don’t it will draw almost as much energy as when it is charging, and you will generate 35-70 kilograms of avoidable carbon dioxide each year. It’s estimated that 95% of the energy used by mobile-phone chargers in the UK is energy wasted in this way. Charge mobile phones instead with this Trevor Bayliss eco-pro charger (21.95) from Ethical Superstore. Environmentally-friendly laptop chargers are currently in development watch this space for Samsung’s fuel-cell dock, which promises to power a laptop running eight hours a day for an entire month without recharging.
Cut heating costs
Working from home might seem like a good, green idea, but extra carbon emissions created by heating and powering your home office may outweigh the savings you make by not commuting. Research suggests that a full-time home-worker emits 2.3 tonnes of CO2 annually, compared to 1.7 tonnes for the average office worker, partly due to the additional use of electricity and heating. So in those months where you can’t enjoy working in the garden, make sure you only have lights switched on in the room you are using, and use a portable heater rather than keeping radiators on all over the house.
