Usage of Concrete Towers as Wind Energy Towers

“A green, renewable energy economy isn’t some pie-in-the-sky, far-off future – it is now. It is creating jobs – now. It is providing cheap alternatives to $140-per-barrel oil – now. And it can create millions of additional jobs, an entire new industry, if we act – now. ~ Excerpts from the speech, ‘A Serious Energy Policy for Our Future’.


Wind energy is emerging as the world leader in the energy market. As per the reports of The Global Wind Energy Council (GWEC), the global trade association for regulating wind energy affairs, 40GW of new wind energy capacity is to be added in the world energy market in 2011. Moreover, the American Wind Energy Association (AWEA) recently reported on April 28 that the US wind power industry installed 1,100 MW and 5,600 MW of wind capacity in the first and second quarters of 2011 alone. 

The potential of wind energy market is tremendous and it is noteworthy to consider the fact in the coming years, almost all major nations, be it the mighty USA or the emerging global economic power, China, all are willing to invest billions of dollars in this industry. Government and private enterprises are enthusiastic about the opportunities that the wind energy market is unfolding for meeting the challenges of the impending future energy crisis. By 2012, it is said that this industry is going to provide employment to millions of people. 

 

North America, Europe and Asia are emerging as dominating leaders in the wind energy market. Glance through any stock investment website or take tips from any investment guru, there is no denying to the fact that in the ultimate analysis, wind energy is here to stay, for the coming decades will rely heavily on this form of energy. Its commercialization has now opened doors for billionaire venture capitalists (VCs) and corporate big wigs to foray in the energy sector and make the most of it. There never was a time better than these years to invest in numerous wind energy companies that are bubbling with oodles of optimism about the prospects of definite and lucrative returns of their eye – popping investments in this sector.

 

 Wind energy is one of the most commercially developed and rapidly growing renewable energy technologies worldwide. In India, the installation wind farms support an industry that grew by 40% in 2011 alone. The Indian & foreign company’s initial target is to generate 20% of electricity from renewable sources by 2015, aspiring to a target of 40% by 2020. The next five years will see the implementation of a large programme of wind farm developments nationwide and international wide, exploiting some of the best and most geographically diverse wind resources in Asia.          

 

One challenge to meet these renewable energy demands is purely physical. Towers must become taller, stronger and stiffer to accommodate both future site constraints and developments in turbine technology. Demands for increasingly higher power output, coupled with a decreasing number of prime sites with high wind availability and good access, means that there is a need to use higher towers to achieve optimal performance in less windy sites. The introduction of turbines with longer blades, together with the fact that wind speeds generally tend to increase with height, mean the need for increasingly taller wind towers.

 

In summary, the next generation of wind farms will demand taller, stronger towers of up to and beyond

100m. In other words, future wind power will be generated from turbines installed on wind towers that stand at twice.

 

The benefits of concrete for wind farms

 

The wind industry’s identified need for increased turbine sizes, rotor diameters and tower heights makes concrete a competitive option. Concrete can offer tall, strong, sophisticated wind farm structures for onshore or offshore deployment in aggressive marine or remote inland environments which require durable materials and details as a matter of course.

Concrete is the serious contender for building durable 100+ mtr high wind towers with the necessary integral design flexibility and more advantages from concrete tower
