Future energy Have you ever thought about the energy providing you electricity for your daily life that nuclear power could take you off from this world (it is not clear what you mean here)? What was your feeling when you watching news about the Fukushima nuclear crisis? What do you think when you see how victims of Chernobyl disaster live today? Good start – the questions are a very good way to get your reader’s attention.) All of those issues are just because of one reason – the safety problem

Harnessing Nuclear Energy The Superior Non-Renewable Alternative? BENJAMIN J DOWDLE UNIVERSITY OF WASHINGTON Throughout the first half of the 20th century‚ scientists and governments throughout the industrial world began to explore the concept of nuclear theory in an attempt to harness the powerful forces that hold together the nucleus of an atom. Unlike non-renewable energy sources‚ such as coal or natural gas‚ nuclear power plants do not emit global warming emissions while operating

GEOTHERMAL ENERGY Geothermal energy is one of energy source types. Geothermal is energy that is gotten from deep of the earth and close parts of the magma with hotwater and its vapour. It is claimed that is useful and practically energy. Geothermal energy sources are argued that is better than other types in variety topics. Despite the fact that geothermal energy have various advantages ; cost‚ location problems and safety should be considerably reasons which are not geothermal energy prefferring

What is the mysterious dark energy that’s causing the expansion of the universe to accelerate? Is it some form of Einstein’s famous cosmological constant‚ or is it an exotic repulsive force‚ dubbed "quintessence‚" that could make up as much as three-quarters of the cosmos? Scientists from Lawrence Berkeley National Laboratory (Berkeley Lab) and Dartmouth College believe there is a way to find out. | | | | The SuperNova/Acceleration Probe‚ SNAP‚ is a satellite designed to study dark energy

object. Work done by force acting on an object in the direction of the force is equal to the product of the magnitude of the force and the displacement covered by the object in the direction of the force. The work done is measured in joule in the SI system after the scientist James Prescott Joule. Erg is the CGS unit of work. Conditions for work to be done: A net force should act on an object. The object must be displaced in the direction of the net force. Work is said to be done when an object

GEOTHERMAL ENERGY 4 December 2013 Introduction Geothermal is derived from the Greek word ‘geo’ which means ‘earth’ and ‘thermal’ meaning ‘heat’‚ therefore geothermal refers to an energy or heat from the earth. In layman’s terms it is referred to power resulting from the thermal activating within the earth’s crust as a result of volcanic activity. Geothermal energy’s resources range from the surfaces just below the earth‚ to the hot rock‚ which heats water deep beneath the earth
