An overview of wind turbines, from the first experimental electric windmills of the 1880s to today's grid-connected machines, and their place in electricity supply.
How turbine design changed over time: horizontal versus vertical axis machines, taller towers, gearboxes and the control systems that keep modern turbines safe.
Ancient wind devices were not wind turbines. This article separates the myths from the record and shows how wind power shifted from mechanical work to electricity.
How windmills were used to pump water and drain land, from Dutch polders to the American plains, and why these machines mattered to farms and railroads.
Who built the first electricity-making windmill? James Blyth, Charles Brush and Poul la Cour all have a claim, and their 1880s and 1890s machines differed widely.
Small wind generators brought lights and radio to farms and remote homes in the early 1900s, before power lines arrived. Here is how they worked and why they faded.
How wind farms appeared, from the first groups of turbines in 1980 to California's wind rush, Denmark's cooperatives and the move to offshore and floating sites.
How wind turbine blades evolved from cloth sails and wooden slats to airfoil shapes, fiberglass and carbon fiber, and why longer blades capture so much more wind.
How the grain-grinding windmill worked, from early Persian vertical-axis mills to European post and tower mills, with the gears, sails and millstones inside.
