Renewable Energy Technology: Green & Sustainable Development

Wind turbines convert the wind's kinetic energy into mechanical power and electricity via a generator, using aerodynamically shaped blades connected to a low speed shaft, gearbox, and high speed shaft.

Explore photovoltaics and concentrated solar power as solar energy technologies that convert sunlight into electricity using PV materials and tracking lenses, while highlighting storage needs to ensure reliability.

Explore solar tracking systems and their types, demonstrating that a two-axis tracker yields up to 2100 kWh/year, about 21.28% more than horizontal axis monthly adjustment, for higher solar energy utilization.

Understand how dust lowers solar panel efficiency and compare cleaning methods from manual to automated robotic systems, including water-based cleaning and cleaning agents.

Understand the water cycle and its role in hydro energy, from ocean evaporation to clouds, precipitation, and fresh water flow between oceans, land, and mountains.

The lecture explores how piezoelectric materials convert mechanical stress from footsteps into electric energy, enabling floor energy harvesting and sustainable power for buildings.

Explore how the United States, China, and Germany advance renewable energy through rising wind, solar, and hydro while coal declines; review global milestones and the push to cut fossil fuels.

Explore how declining solar prices and expanding installations drive a greener future, with solar, wind, hydroelectric, and geothermal energy advancing under supportive environmental policies.
