alternative energy sources
They harness renewable resources and are clean means of power generation. The main functions of these sources include reducing our dependence on fossil fuels, minimizing greenhouse gas emissions, and providing sustainable energy. There are significant differences among alternative energy technologies, such as solar panels which transform sunlight into electric power--or wind turbines capturing the energy of moving air; and hydroelectric systems that use flowing water. These technologies must be efficient and long-lasting, ideally also having smart features to help optimize their performance. Applications range from the residential to office and industrial environment, with potential for home use as well. This will create a greener and more resilient energy infrastructure.
