Denmark fulfilling its fair part of energy requirements with wind power has been widely known as a vital renewable energy producer. Taking its rich legacy of green energy to the next level, the Scandinavian sovereign state has put up a new 3.6 megawatt offshore wind turbine to exceed the one gigawatt wind energy porch and fulfill 25 percent of its total energy needs only by tapping the wind power.

One of the major problems with conventional wind turbines is that their fast moving blades are prone to damage during high winds and they produce noise, which people living in the vicinity don’t really like. To solve the problems encountered with conventional wind turbines, Mecanoo Architects and Delft University of Technology have joined forces to develop a scale model of a bladeless windmill, which is now viewable in front of the on-campus faculty building dedicated to engineering, mathematics and computer science.
The Solar Winds Gathering place by eco-conscious architect and designer Michael Jantzen, is a design proposal for a large, prefabricated, modular, public art project. In this specific formation, the entire gathering place consists of a cluster of 15 specially designed steel wind turbines. Each of the turbines has a large solar cell array mounted on the top. All of the turbines are about 24 feet in diameter, and range from 16 to 36 feet in height. Seven of the fifteen structures are fitted at their bases with 8-foot diameter circular benches, which can seat approximately 60 people.
As we all know that the amount of energy generated by a wind turbine is directly proportional to the wind speed. The higher the wind speed the more energy is generated by the turbine. While wind energy is essential for a clean energy economy, the output of wind turbines installed at low-wind sites is debatable. As an answer to the present condition, General Electric has announced the development of 2.5-120 – the world’s most efficient high-output and first “brilliant” wind turbine.
In an effort to reduce energy consumption and also give visitors at the Texas A&M University-Kingsville (TAMUK) a chance to commute around the campus without emitting a single ounce of harmful carbon dioxide, a team of two engineering students have created a wind energy generating system that feeds two golf carts with renewable energy. The small wind turbine system, which was constructed in-house, feeds batteries, which are then used to recharge golf carts.
One of the main problems with renewable energy, especially wind and solar energy, is the fact that it cannot be produced at all times. While solar energy generating systems shut down or produces less power during an overcast day or after dark, the output of a wind farm too is dependent on the prevailing climate. Moreover, energy storage systems are too expensive and cannot be deployed all over the world. As a solution to this problem, authorities in Belgium are planning to build an artificial island, which will serve as a cost-efficient way to store excess renewable energy from its offshore wind farms.
After the devastating earthquake-triggered Tsunami in March 2011 damaged the Daiichi nuclear reactor in Fukushima, the Japanese government announced plans to move to renewable ditching the 54 nuclear reactors in the country. While all but two nuclear power plants in the country have been shut down, the Japanese government has now announced a plan to build the world’s largest offshore wind farm, off the cost of Fukushima, where the nuclear disaster happened.
In wind turbines, the length of the blades is generally proportional to the amount of power the turbine will generate. Moreover, since bigger wind turbines are easy to maintain, utility companies prefer to make use of large wind turbines rather than a farm of small turbines to generate the same amount of power. Last year we reported about Siemens quest to build the world’s largest wind turbine blades that measured 75 meters in length and today we have news coming from Blade Dynamics, which is developing wind turbine blades that are up to 100 meters in length.
News recently surfaced that Uruguay is planning to become the world leader in wind energy generation by erecting enough turbines to produce 30 percent of its total energy consumption, China has announced that it is now the world leader in wind and hydroelectric power according to its total installed capacity. China Electricity Council has just made an announcement that the country’s installed capacities for wind and hydro power have grown to become the world’s largest.
Uruguay, the small South American country, which till date has been known mostly because its human population is outnumbered by its cattle herd, could soon be adorned with an environmentally friendly cap as the country is aiming to produce 90 percent of its electricity consumption by means of renewable sources. The president of the UTE state electric company and the national energy director has recently announced that the electricity company has signed contracts to buy electricity from 20 private wind farms that are still to be constructed.
