Electric utility

An electric utility is an electric power company (often a public utility) that engages in the generation, transmission, and distribution of electricity for sale generally in a regulated market. The electrical utility industry is a major provider of energy in most countries. It is indispensable to factories, commercial establishments, homes, and even most recreational facilities. Lack of electricity causes not only inconvenience, but also economic loss due to reduced industrial production.

Electric utilities include investor owned, publicly owned, cooperatives, and nationalized entities. They may be engaged in all or only some aspects of the industry. Electricity markets are also considered electric utilities--these entities buy and sell electricity, acting as brokers, but usually do not own or operate generation, transmission, or distribution facilities. Utilities are regulated by local and national authorities.

Electric utilities are facing increasing demands according to Black & Veatch's annual utility survey, based on input from 700 utility participants, for 2011 the top-three concerns were aging infrastructure, reliability (no. 1 in 2010) and regulation (no. 2 in 2010).

Electricity

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and electric current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.

In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:

Duke University

Duke University is a private research university located in Durham, North Carolina, United States. Founded by Methodists and Quakers in the present-day town of Trinity in 1838, the school moved to Durham in 1892. In 1924, tobacco and electric power industrialist James Buchanan Duke established the Duke Endowment, at which time the institution changed its name to honor his deceased father, Washington Duke.

The university's campus spans over 8,600 acres (35 km²) on three contiguous campuses in Durham as well as a marine lab in Beaufort. Duke's main campus—designed largely by architect Julian Abele—incorporates Gothic architecture with the 210-foot (64 m) Duke Chapel at the campus' center and highest point of elevation. The first-year-populated East Campus contains Georgian-style architecture, while the main Gothic-style West Campus 1.5 miles away is adjacent to the Medical Center. Duke is also the 7th wealthiest private university in America with $11.4 billion in cash and investments in fiscal year 2014.
