two towers are linked via three skybridges

.The two towers are linked via three skybridges, each holding a 225KW wind turbine, totalling to 675kW of wind power production. Each of these turbines measure 29 m (95 ft) in diameter, and is aligned north, which is the direction from which air from the Persian Gulf blows in. The sail-shaped buildings on either side are designed tofunnel wind through the gap to provide accelerated wind passing through the turbines. This was confirmed by wind tunnel tests, which showed that the buildings create an S-shaped flow, ensuring that any wind coming within a 45° angle to either side of the central axis will create a wind stream that remains perpendicular to the turbines. This significantly increases their potential to generate electricity

Bahrain World Trade Center


The Bahrain World Trade Center (also called Bahrain WTC or BWTC) is a 240 m (787 ft) high twin tower complex located in Manama, Bahrain. The towers were built in 2008 by the multi-national architectural firm Atkins. It is the first skyscraper in the world to integrate wind turbines into its design.
This 50-floor structure is constructed in close proximity to the King Faisal Highway, near popular landmarks such as the towers of BFH, NBB, Abraj Al Lulu and the scenic Pearl Roundabout. It currently ranks as the second tallest building in Bahrain, after the twin towers of the Bahrain Financial Harbour. The project has received several awards for sustainability, including;
The 2006 LEAF Award for Best Use of Technology within a Large Scheme.
The Arab Construction World for Sustainable Design Award

solar power production

Compared to wind, India lags behind in solar power production. Only about 0.5% of the country’s power comes from solar. This is despite the availability of plenty of solar radiation in most of the country. In fact, India is one of the best places in the world to develop solar solutions for energy. Compared to wind, solar radiation is a much more abundant resource in India. Insolation levels are high all over the country, allowing for de-centralized, off-grid approaches to power production. Not only does this lead to a more stable system (because of less risk of any large scale power outages), but it is extremely efficient in terms of land area used (rooftops and open terraces can become energy sinks) as well as in terms of energy conservation (because inefficient, expensive and long transmission lines can be avoided).

wind also comes with it’s unique disadvantages


However, wind also comes with it’s unique disadvantages. The most prominent of these is the fact that wind patterns vary seasonally and geographically. This means that it can only be tapped to make electricity in some localized parts of the country, and the electricity production will vary throughout the year. The map on the right shows how just a few regions of the country are suitable for wind power harvesting. The wind patterns in India have been mapped and the areas with highest wind energy potential have been identified:
For those parts of the country without sustained strong winds, wind power may not be the best answer

wind and solar energy sources


This trend is set to continue, with the country doubling it’s energy consumption in the next 20 years. Finding alternatives to fossil fuel-based energy sources is vital to India’s future if it wants to continue sustained growth.
Careful analysis of future trends is important for providing the right information to companies wanting to get involved in energy production.
Since wind and solar energy sources are widely popular and considered to be important in India’s development of renewable energy (RE) ,an important place to begin the analysis is by studying the inherent potential for these two energy sources. In this article I will limit my analysis of the RE sector to these two energy sources.

India is undergoing an energy crisis.

India is undergoing an energy crisis. 53% of the country’s current power needs come from coal. This highly polluting source of energy is bound to run out someday. Compared to the West, India’s energy consumption is growing at break-neck speed. As India’s poor millions advance out of poverty, they are consuming more and more power, outstripping national power production. The negative gap between consumption and production has been increasing exponentially in the past two decades, forcing the government to buy increasing quantities of power from abroad.
