NANO-SCIENCE: INCREASING USE IN EVERYDAY APPLICATIONS In some conversations today you hear a term called ”nanotechnology”. Also casually translated as a dense technology on a very small scale.

WIND POWER CAN BECOME THE MAIN ELECTRICITY PROVIDER Last year the total installed  wind capacity was 54.6 gigawatts globally. And according to the Global Wind Energy Council today’s total installed windmills produce circa 487 gigawatts.The first place goes to the Chinese market with a total share of  42.7%. In order to meet their increasing electronic needs the country installed 23.3 gigawatts of new wind mill farms and if the growth stays at the same pace they can provide 26% of their own market supply by the end of 2030, says a study of the MIT (Massachusetts Institute of Technology) USA. On the second place you have USA, where less than 8.3 gigawatts windmill power was installed, supplying 4.7 % of the entire electricity in the country. In this article we”re going to look at which modern windmills are mainly used on today’s market and what the (dis)advantages are from this ”new” invention. And lastly, why their is a big spurt in investments and growth in the industry. BY RENEE VAN WESEP
