Magnetic storm A magnetic storm is a period of rapid Magnetic Field variation. It can last from hours to days. Magnetic storms have two basic causes: The Sun sometimes emits a strong surge of solar wind called a coronal mass ejection. This gust of solar wind disturbs the outer part of the … Read more
KUSUM Scheme: Energizing India’s Agriculture Sector The Indian agricultural sector, the backbone of the nation’s economy, faces a multitude of challenges, including energy insecurity, reliance on fossil fuels, and environmental degradation. To address these issues and usher in a sustainable future for Indian agriculture, the Ministry of New and Renewable Energy (MNRE) launched the Kisan … Read more
The photoelectric effect The photoelectric effect is the emission, or ejection, of electrons from the surface of, generally, a Metal in response to incident Light.A material that can exhibit The photoelectric effect is said to be photoemissive, and the ejected electrons are called photoelectrons. The process was discovered by Heinrich Hertz in 1887. Attempts to … Read more

Sources of Energy: Conventional and Nonconventional Sources – Energy is one of the most important component of economic Biomass. These substances can be burnt to produce heat energy which can be used in the generation of electricity. Thus, the energy produced from the biomass is known as biomass energy. There are three forms of biomass: … Read more
Sunlight is Earth’s most abundant energy source and is delivered free of charge. Indeed, the energy from sunlight reaching the land surface of the earth is thousands of times greater than the world’s current total annual consumption of energy. Yet harnessing sunlight’s energy content directly—rather than indirectly in fossil fuels, wind, or hydroelectric power—makes only a small contribution to humanity’s energy … Read more
