Wind turbines have been used for household electric power generation in conjunction with battery storage over many decades in remote areas. [ 105 ] Examples of small-scale wind power projects in an urban setting can be found in New York City , where, since 2009, several building projects have capped their roofs with Gorlov-type helical wind ...
Modern wind turbines produce significantly less noise than older designs. Turbine designers work to minimise noise, as noise reflects lost energy and output. Noise levels at nearby residences may be managed through the siting of turbines, the approvals process for wind farms, and operational management of the wind farm. [ 25 ]
The Vattenfall utility company study found Hydroelectric, nuclear stations and wind turbines to have far less greenhouse emissions than other sources studied.. A typical study of a wind farm's Life cycle assessment, when not connected to the electric grid, usually results in similar findings as the following 2006 analysis of 3 installations in the US Midwest, where the carbon dioxide (CO 2 ...

This chart lets you estimate the wind chill without having to do the math yourself. Find the value closest to the temperature at the top of the chart and the wind speed to the left.
The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
The Santa Ana winds of Southern California can be visualized in several ways. You can see their effects as palm trees sway in the morning light or when clean-up crews arrive to deal with branches ...
