Turbulence by David Alan Earnest
... • Wind is caused by the weight of the air. Since cold air is heavier than warm air, it has a greater pressure and sinks. When this air is heated up by the sun, it rises and is replaced by new cool air that rushes in. Usually, wind blows from areas of high pressure to areas of low pressure. ...

Environmental impact of wind power
The environmental impact of wind power, when compared to the environmental impacts of fossil fuels, is relatively minor. According to the IPCC, in assessments of the life-cycle global warming potential of energy sources, wind turbines have a median value of between 12 and 11 (gCO2eq/kWh) depending, respectively, on whether offshore or onshore turbines are being assessed. Compared with other low carbon power sources, wind turbines have some of the lowest global warming potential per unit of electrical energy generated.While a wind farm may cover a large area of land, many land uses such as agriculture are compatible with it, as only small areas of turbine foundations and infrastructure are made unavailable for use.There are reports of bird and bat mortality at wind turbines as there are around other artificial structures. The scale of the ecological impact may or may not be significant, depending on specific circumstances. Prevention and mitigation of wildlife fatalities, and protection of peat bogs affect the siting and operation of wind turbines. As a number of wind farms built on peatland, have resulted in environmental disasters, most notably in 2003, and 2008.There are anecdotal reports of negative health effects from noise on people who live very close to wind turbines. Peer-reviewed research has generally not supported these claims. Although research on livestock suggests that close proximity to wind turbines does increase blood cortisol stress levels.Wind turbines have been criticised as having a visual impact on the landscape. When conflicts arise the arguments often centre on the scenic and heritage values of a landscape.
