Introduction
Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed; matter and energy may also be converted to one another. The unit of measurement for energy in the International System of Units (SI) is the joule (J).
Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass.
All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are driven primarily by radiant energy from the sun. The energy industry provides the energy required for human civilization to function, which it obtains from energy resources such as fossil fuels, nuclear fuel, renewable energy, and geothermal energy.

Selected article
The major petroleum strikes that began the rapid growth in petroleum exploration and speculation occurred in Southeast Texas, but soon reserves were found across Texas and wells were constructed in North Texas, East Texas, and the Permian Basin in West Texas. By 1940 Texas had come to dominate U.S. production. Some historians even define the beginning of the world's Oil Age as the beginning of this era in Texas.

Tropical cyclones feed on the heat released when moist air rises and the water vapor condenses.

Selected biography
Born in Ireland, Thomson studied at the University of Glasgow, Scotland. On graduating, he became a mathematics teacher at the Royal Belfast Academical Institution. During his life Thomson published more than 600 scientific papers and filed over 70 patents.
As early as 1845 Thomson pointed out that the experimental results of William Snow Harris were in accordance with the laws of Coulomb. Over the period 1855 to 1867, Thomson collaborated with Peter Guthrie Tait the Treatise on Natural Philosophy that unified the various branches of physical science under the common principle of energy. His inventions included the current balance for the precise specification of the ampere, the standard unit of electric current.
In 1893, Thomson headed an international commission to decide on the design of the Niagara Falls power station. Despite his previous belief in the superiority of direct current electric power transmission, he agreed to use alternating current after seeing a Westinghouse demonstration at the Chicago World's Fair.

Quotations
- "Breaking the dependence on oil is, in my view, a matter of political will. A consistent policy will turn obstacles into opportunities. To hide behind excuses of ignorance or economic considerations is not leading us to a sustainable future." – Mona Sahlin, 2006
- "America is addicted to oil, which is often imported from unstable parts of the world. The best way to break this addiction is through technology." – George W. Bush, 2006
- "Energy independence [for India] has to be our nation's first and highest priority. We must be determined to achieve this within the next 25 years i.e. by the year 2030." – Abdul Kalam, 2005
- "Energy security is assuming a strategic significance once reserved for territorial security, and the global environmental challenges from energy production and use are amongst our most pressing." – John Howard, 2006
