Hydrogen Energy Hydrogen is the most abundant. Hydrogen gas has remarkable characteristics including colorless, tasteless and invisible that make it hotly pursued. It can also be transformed into a renewable, nonpolluting and zero-emission energy resource. It's viewed as the foundation of the new energy economy. The quest for hydrogen energy started way back in 1776 by the British researcher Henry Cavendish.  He initially recognized it as a particular component after he created hydrogen gas by oppressing zinc metal to hydrochloric corrosive. Henry Cavendish made another wonderful disclosure during an exhibition to the Royal Society of London when he acquainted a sparkle with hydrogen gas, delivering water simultaneously. This noteworthy advancement prompted his decision that water (H2O) is made out of hydrogen and oxygen. From that point forward, hydrogen innovation has filled quickly, and today, it is utilized as a fuel source to control vehicles, electric frameworks, and the crea...

Sustainable Energy in India It isn't covered up any longer that India has a huge supply of inexhaustible assets and it has one of the biggest projects in the world for sending sustainable power source items and frameworks. India is the main nation on the planet to have a restrictive service for sustainable power source improvement, the Ministry of New and Renewable Energy (MNRE) which has propelled one of the world's biggest and aggressive projects on the sustainable power source. This article gives a short review of different sustainable power source assets, their status in India, the financial effect of sustainable power source assets (RES), challenges related with it and the eventual fate of RES in India. Renewable Energy versus Coal Vitality is viewed as the most critical structure hinder in human advancement and it is a key factor that impacts the manageable improvement of any country. The ordinary sources have a scary shadow on our present and future worldwid...

The visible and near visible (Ultra-Violet and near Infrared) electromagnetic radiation that is emitted by the Sun is termed as Solar Radiation . The solar radiation has a spectral or wavelength, distribution that corresponds to different energy levels, short wavelength radiation has a higher energy than long wave length radiation. These solar radiation convert into useful forms of energy such as "heat and electricity", using a variety of technologies. The technical feasibility and economical operation of these technologies at a specific location depends on the available solar radiation or solar resource. Photovoltaic Effect :- Photo-voltaics are the technology for conversion of solar radiation (sunlight) directly into electricity. A photo-voltaic cell also called a PV or a solar cell is the device used for this purpose. The PV technology has  emerged as a promising technology to generate electricity for small applications like lighting and meeting other electric...

Wind is the natural movement of air across the land or sea. Wind is caused by uneven heating and cooling of the earth's surface and by the earth's rotation. Land and water areas absorb and release the different amount of heat received from the sun. As warm air rises, cooler air rushes in to take its place, causing local winds. The rotation of the earth changes the direction of the flow of air. Wind is simple air in motion. It is caused by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of very  different types of land and water, it absorbs the sun"s heat at different rates. During the day, the air above the land heats up more quickly than the air over water. The warm air over the land expands and rises and the heavier, cooler air rushes in to take its place, creating winds. At night, the winds are reversed because the air cools more rapidly over land than over water. Today, wind energy is mainly used to generate electr...
