Energy Sources

 Energy Sources Biofuels Coal Electricity Geothermal Hydrogen Hydropower Petroleum – Oil and Natural Gas Solar Energy Uranium – Nuclear Energy Wind Energy Energy is essential. It is embodied in everything we use. To compare sources of energy effectively, we need to understand what it is and how it works. What is Energy? It comes from many sources and in many forms. The forms of energy are classified in two general categories: potential and kinetic. Potential energy is energy stored in an object. Chemical, mechanical, ...

Weatherization

Weatherization (American English) or weatherproofing (British English) is the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation, and wind, and of modifying a building to reduce energy consumption and optimize energy efficiency. Weatherization is distinct from building insulation, although building insulation requires weatherization for proper functioning. Many types of insulation can be thought of as weatherization, because they block drafts or protect from cold winds. Whereas insulation...

Modi calls for an 'energy revolution'

In the heart of Ahirwal-dominated Haryana’s Mahendergarh district on Wednesday, BJP’s fire brand ambassador and Prime Minister Narendra Modi slammed Chief Minister Bhupinder Singh Hooda for using state machineries, especially the police force, to create hurdles between him and the people of the state.  “I was pained when I heard that old-age people walked to the venue to listen to me without bothering about distance. The state police gave parking space far away from the rally venue to create obstacles.  "I want to ask the...

Energy development

Energy development[1][2][3] is a field of endeavor focused on making available sufficient primary energy sources[4] and secondary energy forms to meet the needs of society.[5][6][7][8][9] These endeavors encompass those which provide for the production of conventional, alternative and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation[note 2] and efficiency measures[note 3] reduce the impact of energy development, and can have benefits to society with changes in economic cost...

Hydroelectricity

Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010,[1] and is expected to increase about 3.1% each year for the next 25 years.Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010....

Photosensitivity

Photosensitivity is the amount to which an object reacts upon receiving photons, especially visible light. In medicine, the term is principally used for abnormal reactions of the skin, and two types are distinguished, photoallergy and phototoxicity.[1][2] The photosensitive ganglion cells in the mammalian eye are a separate class of light-detecting cells from the photoreceptor cells that function in vision.Sensitivity of the skin to a light source can take various forms. People with particular skin types are more sensitive to sunburn. Particular...

Artificial photosynthesis

Artificial photosynthesis is a chemical process that replicates the natural process of photosynthesis, a process that converts sunlight, water, and carbon dioxide into carbohydrates and oxygen. The term is commonly used to refer to any scheme for capturing and storing the energy from sunlight in the chemical bonds of a fuel (a solar fuel). Photocatalytic water splitting converts water into Hydrogen Ions and oxygen, and is a main research area in artificial photosynthesis. Light-driven carbon dioxide reduction is another studied process, replicating...

Solar architecture

Solar architecture is the integration of solar panel technology with modern building techniques. The use of flexible thin film photovoltaic modules provides fluid integration with steel roofing profiles that enhances the building's design. Orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air also constitute as solar architecture. Initial development of solar architecture has been limited by the rigidity and weight of standard solar...

Solar thermal energy

Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy or electrical energy for use in industry, and in the residential and commercial sectors. The first installation of solar thermal energy equipment occurred in the Sahara Desert approximately in 1910 and was a steam engine without a kettle and fire but with a mirror system for sun light collection to heat water for the needed steam pressure. Because of the influence of World War I, liquid fuel was better developed and the Sahara...

Photovoltaics

Photovoltaics (PV) is a method of generating electrical power by converting sunlight into direct current electricity using semiconducting materials that exhibit the photovoltaic effect. A photovoltaic system employs solar panels composed of a number of solar cells to supply usable solar power. Power generation from solar PV has long been seen as a clean sustainable[1] energy technology which draws upon the planet’s most plentiful and widely distributed renewable energy source – the sun. The direct conversion of sunlight to electricity occurs without...

Solar thermal collector

A solar thermal collector collects heat by absorbing sunlight. A collector is a device for capturing solar radiation. Solar radiation is energy in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The quantity of solar energy striking the Earth's surface averages about 1,000 watts per square meter under clear skies, depending upon weather conditions, location and orientation.The term "solar collector" commonly refers to solar hot water panels, but may refer to installations such as solar parabolic...
