History of renewable energy
The history of renewable energy reflects a long pursuit of energy independence and sustainability.
Their use dates back centuries, even before the industrial era, with examples like windmills and waterwheels used for mechanical tasks.
Their modern usage began in the 19th century with technological advances. Pioneers like Poul la Cour shaped wind energy development. Hydropower boomed in the 20th century with large dam constructions, while solar energy took off in the 1950s with the invention of photovoltaic cells.

When was the first wind turbine invented?
The first wind turbine was built in 1888 by American engineer Charles F. Brush. It stood 18 meters tall, weighed 36 tons, and had 144 wooden blades. It produced just 12 kilowatts, but marked a milestone in electricity generation.

When was the first photovoltaic system created?
The photovoltaic system was invented in 1954 by physicists at Bell Labs. Their silicon solar cell had 6% efficiency, launching the practical use of solar energy — first in satellites, then on Earth.
