Electrical and Technology

There are other energy sources which are not so popular but are now gaining importance such as:- Hydrogen Energy Chemical Sources of Energy (Fuel Cells) Geo-Thermal Energy Ocean  and Tidal Energy Biofuels Animal Energy Hydrogen Energy:- In the case of Hydrogen energy , electricity is produced through an electrochemical reaction between hydrogen and oxygen. Hydrogen can be produced from the electrolysis of water using solar energy. It can be extracted from sewage gas, natural gas, naptha  or biogas . Fuel cells can be very widely used for a wide range of applications once they become commercially viable. Hydrogen as Fuel:- Hydrogen as a gas is so much lighter than air that it rises fast and is quickly ejected from the  atmosphere . It found only in the compound which is water and is result of hydrogen combining with oxygen. Hydrogen, when combined with carbon, forms different compounds like methane, coal and petroleum. Hydrogen is also available

Energy use in India is quite appreciable for commercial and industrial applications. The increase is almost 5% per year. The energy resources used are  : COAL BIOMASS (Wood and Cow dung) OIL (Petrol, Diesel, and Kerosene) ELECTRICITY (about 70% of electricity in India is generated by polluting coal.) Energy exists in many forms. Broadly speaking, we can classify energy into two types, potential and kinetic energy. Potential Energy The potential energy is the stored energy and the energy of position (gravitational). Potential Energy exists in many forms. 1). Chemical Energy:- The energy stored in the bonds of atoms and molecules is called chemical energy . The examples of stored chemical energy are petrol, diesel, kerosene,  natural gas, coal, wood and other biomass. The stored chemical energy is released as heat when these fuels burn. 2). Nuclear Energy:- The energy stored in the nucleus of an atom, the energy that holds the nucleus together is called
