According to the Worldwatch Institute, in 2009 wind power contributed 2% to global electricity consumption worldwide and global wind power capacity increased by 31%, the highest rate in the last 8 years despite the recession. However this growth is unlikely to continue in 2010 and the US market is facing increased competition according to recent research. It has been estimated that 6.3-7.1 GW of wind capacity will be installed in the US in 2010 – a 40-60% decrease from 2009, the first time since 2004 that US wind energy did not see an increase in the previous years growth figure likely due to the turbulent financial environment. However the study found that providing the correct policy frameworks are in place, the US wind industry can add 165 GW of capacity, representing $330bn in investments by 2025.

Wind power growth set to halt after 2009 peak
Tuesday, August 3rd, 2010What is Wind Energy?
Tuesday, August 25th, 2009Wind Energy is the energy found in the wind that is grasped by Renewable Energy Systems Technology (REST) in order to generate power for human benefit. Wind turbines are the REST used to collect the wind resource and generate power. Today, wind turbines are used to generate electricity from the wind. There are two types of wind turbines, the horizontal axis turbine which is the most common one and the vertical axis turbine. The horizontal wind turbine is the most efficient and cost effective. Most of the wind turbines used for electricity generation are of this type. Wind turbines can be found in many sizes and outputs, from small battery charging turbines to the largest machines used to supply electricity to the grid.
