Made By – Pritam Singh & Rohan Rawat Guided By- Swamini Wagh SOURCES OF ENERGY

Slide 2: 

Energy Is needed To do work. ENERGY

Slide 3: 

Electrical energy is energy newly derived from electrical potential energy. When loosely used to describe energy absorbed or delivered by an electrical circuit "electrical energy" refers to energy which has been converted from electrical potential energy ELECTRICAL ENERGY

Slide 4: 

Light or visible light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. LIGHT

Slide 5: 

Sound energy is the energy produced by sound vibrations as they travel through a specific medium. Sound vibrations cause waves of pressure which lead to some level of compression and rarefaction in the mediums through which the sound waves travel . SOUND

Slide 6: 

Heat energy (or just heat ) is a form of energy which transfers among particles in a substance (or system) by means of kinetic energy of those particle. In other words, under kinetic theory, the heat is transfered by particles bouncing into each other. HEAT

Slide 7: 

Gravitational energy is the force of attraction between two objects that have mass. On planet Earth, this force is responsible for keeping us from floating off into the atmosphere along with all of the other material on the earth’s surface. GRAVITIONAL ENERGY

Slide 8: 

Nuclear power is the use of sustained nuclear fission to generate heat and do useful work. Nuclear power plants provide about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity. ATOMIC ENERGY

Slide 9: 

FUEL

Slide 10: 

Fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. FUEL

Slide 11: 

The Sun is the star at the center of the Solar System. It is almost perfectly spherial and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 2×10 30 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. SUN

Slide 12: 

Less than 2% consists of heavier elements, including oxygen, carbon, neon, iron, and others. ] This amount (1.69%) is nonetheless enough matter to build 5,628 planets the mass of the Earth. The Sun's stellar classification, based on spectral class, is G2V, and is informally designated as a yellow dwarf , because its visible radiation is most intense in the yellow-green portion of the spectrum and although its color is white, from the surface of the Earth it may appear yellow because of atmospheric scattering of blue light SUN

Slide 13: 

The sources of energy which have been in use for a long time, e.g., coal, petroleum, natural gas and water power. They are exhaust able except water. The resources which are yet in the process of development over the past few years. It includes solar, wind, tidal, biogas, and biomass, geothermal. They are inexhaustible.
