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.

The wind resource in many parts of Texas is very large. Farmers may lease their land to wind developers, creating a new revenue stream for the farm. The wind power industry is also creating thousands of jobs for local communities and for the state. Texas is seen as a profit-driven leader of renewable energy commercialization in the United States. The wind boom in Texas was assisted by expansion of the state’s Renewable Portfolio Standard, use of designated Competitive Renewable Energy Zones, expedited transmission construction, and the necessary Public Utility Commission rule-making.
The Roscoe Wind Farm (781 MW) is the state's largest wind farm. Other large wind farms in Texas include: Horse Hollow Wind Energy Center, Sherbino Wind Farm, Capricorn Ridge Wind Farm, Sweetwater Wind Farm, Buffalo Gap Wind Farm, King Mountain Wind Farm, Desert Sky Wind Farm, Wildorado Wind Ranch, and the Brazos Wind Farm.

Selected biography
Between 1992 and 1995, after Soviet president Mikhail Gorbachev's 'perestroika' economic reforms permitted the opening of small private businesses, Abramovich founded five companies that eventually evolved to specialize in the trading of oil and oil products. With the approved by Boris Yeltsin, in 1995 Roman Abramovich and partner Boris Berezovsky paid $100m for a controlling interest in the major Russian Sibneft oil company, then valued at $150 million. Berezovsky subsequently sold his stake to Abramovich after fleeing to London. In September 2005 Abramovich sold his interest in Sibneft to state energy giant Gazprom for $13 billion.
Despite maintaining that his primary residence is Moscow, in 2006 Abramovich was named as the second-wealthiest person in the United Kingdom. His property investments and other assets were estimated at £10.8 billion. In June 2003, Abramovich became the owner of the companies that control Chelsea Football Club (soccer club). He also became the world's greatest spender on luxury yachts, with four boats in what the media have called the 'Abramovich Navy'.
Although he rarely visits the area, in October 2005 Abramovich was reappointed governor of the impoverished Chukotka Autonomous Okrug in the Russian Far East where he has made significant financial contributions. He was originally elected to the governorship in 1999.
