Green technology, often referred to as clean technology or greentech, encompasses a wide range of techniques, materials, and innovations that are designed to use resources in a more sustainable way while reducing environmental impacts. It aims to solve problems related to waste, pollution, resource depletion, and climate change through more efficient energy use, renewable energy sources, and conservation of natural resources. Key areas of focus include energy generation through solar, wind, and hydroelectric means; energy efficiency in buildings and transportation; water purification and waste management systems; and the development of eco-friendly materials and chemicals.
