Energy research focuses on understanding and developing sustainable sources of energy to power our society. This includes studying renewable energy sources such as solar, wind, and hydroelectric power, as well as exploring ways to increase energy efficiency and reduce reliance on fossil fuels. Researchers in this field also work on improving energy storage technologies, developing smart grid systems, and addressing the environmental impact of energy production and consumption. Overall, energy research is critical for meeting the growing global demand for energy while reducing its negative environmental and social impacts.
