102.Too many wind turbines causes "dirty air"
The plethora of wind farms added to the U.S. power grid in recent years clearly indicates the rapidly growing demand of wind power. But it is important to know what number is the limit.

101.Is China Exploiting Its Position As A Major Supplier Of Rare-Earths?
China is still confident that the dependency on it can never be eliminated and it will maintain its position in the global rare-earth metals market for a long period of time. But how long will the international community allow it to exploit its position, before finding other sources?

100.The Effects Of Extracting Rare-Earth Metals In China
China aims to speed up the industrial application and promotion of the process of separation of low-carbon and low-sodium free ammonia nitrogen rare earth oxide and purification technology along with finalizing the demonstration of the industrial application of rare earth metal ore.

99.Carbon Tax to Reduce Pollution
Several countries have gone as far as to implement different measures in order to reduce the carbon dioxide pollution. Carbon tax is one such initiative taken by the UK government.

98.Can Wind Farms Steal Each Other's Energy?
Wind power is growing faster than ever. According to several scientists, it is even possible to have so many wind turbines, which can steal each other's wind.

97.How Do Birds Navigate By Magnet Fields?
The visual magnetic receptor and the magnetite receptor harmonize one another, with birds making use of the receptors present in their beaks just like GPS and utilizing visual magnetic details just like a compass to find out which way they are facing.

96.Rare-earth Trafficking Out of China
Rare earth elements provide lively functions in all modern day technologies, and China holds an almost comprehensive monopoly of the market.

95.The Developing Role of Permanent Magnets in Renewable Energy
The key way that permanent magnets are generated is by heating a ferromagnetic material to an important high temperature. Permanent magnets are vital for their industrial uses particularly when it comes to power generation and electric motors.
