PSNH
Public Service of New Hampshire, commonly known as PSNH, was the largest public utility in the U.S. state of New Hampshire for decades. Founded in 1926, it sold natural gas and electricity, and for a time ran electric street-railway services and, later, bus service. The company was bought in 1992 and became part of what is now Eversource Energy. History Large-scale electricity production came to New Hampshire in 1882 when the New England Weston Electric Light Company of Boston built a generating station in Manchester, New Hampshire, Manchester, on the property of the Amoskeag Manufacturing Company. In 1885 the Manchester Electric Light Company bought the Weston property in the city and in 1901 merged with the Manchester Traction, Light and Power Company - so named because electric trolley cars, the "traction" portion of the name, were a major customer of electricity producers. PSNH records indicate that at least 39 small electric companies that were in business before 1900 wer ...

Public Utility Holding Company Act
The Public Utility Holding Company Act of 1935 (PUHCA), also known as the Wheeler-Rayburn Act, was a US federal law giving the Securities and Exchange Commission authority to regulate, license, and break up electric utility holding companies. It limited holding company operations to a single state, thus subjecting them to effective state regulation. It also broke up any holding companies with more than two tiers, forcing divestitures so that each became a single integrated system serving a limited geographic area. Another purpose of the PUHCA was to keep utility holding companies engaged in regulated businesses from also engaging in unregulated businesses. The act was based on the conclusions and recommendations of the 1928-35 Federal Trade Commission investigation of the electric industry. On March 12, 1935, President Franklin D. Roosevelt released a report he commissioned by the National Power Policy Committee. This report became the template for the PUHCA. The political batt ...

Energy In New England
In physics, 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. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common 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, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ...

Binary Cycle
A binary cycle is a method for generating electrical power from geothermal resources and employs two separate fluid cycles, hence binary cycle. The primary cycle extracts the geothermal energy from the reservoir, and secondary cycle converts the heat into work to drive the generator and generate electricity. Binary cycles permit electricity generation even from low temperature geothermal resources (<180°C) that would otherwise produce insufficient quantities of steam to make flash power plants economically viable. However, due to the lower temperatures binary cycles have low overall efficiencies of about 10-13%.

Portsmouth, New Hampshire
Portsmouth is a city in Rockingham County, New Hampshire, United States. At the 2020 census it had a population of 21,956. A historic seaport and popular summer tourist destination on the Piscataqua River bordering the state of Maine, Portsmouth was formerly the home of the Strategic Air Command's Pease Air Force Base, since converted to Portsmouth International Airport at Pease. History American Indians of the Abenaki and other Algonquian languages-speaking nations, and their predecessors, inhabited the territory of coastal New Hampshire for thousands of years before European contact. The first known European to explore and write about the area was Martin Pring in 1603. The Piscataqua River is a tidal estuary with a swift current, but forms a good natural harbor. The west bank of the harbor was settled by European colonists in 1630 and named Strawbery Banke, after the many wild strawberries growing there. The village was protected by Fort William and Mary on what is now ...

Amoskeag Manufacturing Company
The Amoskeag Manufacturing Company was a textile industry, textile manufacturer which founded Manchester, New Hampshire, United States. From modest beginnings it grew throughout the 19th century into the largest cotton textile plant in the world. At its peak, Amoskeag had 17,000 employees and around 30 buildings. In the early 20th century, changing economic and social conditions occurred as the New England textile industry shifted to the Southern U.S., and the business went bankrupt in 1935. Many decades later, the original mills were refurbished and renovated, and now house offices, restaurants, software companies, college branches, studio, art studios, apartments and a museum. History Origins In May 1807, Samuel Blodgett completed a canal and lock (water transport), lock system beside the Merrimack River at Derryfield. His enterprise allowed boats traveling between Concord, New Hampshire, Concord and Nashua, New Hampshire, Nashua to bypass Amoskeag Falls, opening the regio ...

Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...
