District Heating
District heating (also known as heat networks) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heater, space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heating plant, heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants. District heating is ranked number 27 in Drawdown (climate), Project Drawdown's 100 solutions to climate change, global warming. His ...

Geothermal Heating
Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption. Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter. Geothermal energy originates from the heat retained within the Earth since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with temper ...

A district is a type of administrative division that in some countries is managed by the local government. Across the world, areas known as "districts" vary greatly in size, spanning regions or counties, several municipalities, subdivisions of municipalities, school district, or political district. Etymology The word "district" in English is a loan word from French. It comes from Medieval Latin districtus–"exercising of justice, restraining of offenders". The earliest known English-language usage dates to 1611, in the work of lexicographer Randle Cotgrave. By country or territory Afghanistan In Afghanistan, a district ( Persian ) is a subdivision of a province. There are almost 400 districts in the country. Australia Electoral districts are used in state elections. Districts were also used in several states as cadastral units for land titles. Some were used as squatting districts. New South Wales had several different types of districts used in the 21st cen ...

Eastern Bloc
The Eastern Bloc, also known as the Communist Bloc (Combloc), the Socialist Bloc, the Workers Bloc, and the Soviet Bloc, was an unofficial coalition of communist states of Central and Eastern Europe, Asia, Africa, and Latin America that were aligned with the Soviet Union and existed during the Cold War (1947–1991). These states followed the ideology of Marxism–Leninism, in opposition to the Capitalism, capitalist Western Bloc. The Eastern Bloc was often called the "Second World", whereas the term "First World" referred to the Western Bloc and "Third World" referred to the Non-Aligned Movement, non-aligned countries that were mainly in Africa, Asia, and Latin America but notably also included former Tito–Stalin split, pre-1948 Soviet ally Socialist Federal Republic of Yugoslavia, Yugoslavia, which was located in Europe. In Western Europe, the term Eastern Bloc generally referred to the USSR and Central and Eastern European countries in the Comecon (East Germany, Polish Peo ...

Solar Energy
Solar energy is the radiant energy from the Sun's sunlight, light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include designing a building for better daylighting (architecture), daylighting, selecting materials with favorable thermal mass or light-dispersing properties, and organizing spaces that ventilation (architecture), naturally circulate air. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technolo ...

Geothermal Energy
Geothermal energy is thermal energy extracted from the crust (geology), crust. It combines energy from the formation of the planet and from radioactive decay. Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since Roman times. Geothermal power (generation of electricity from geothermal energy), has been used since the 20th century. Unlike wind and solar energy, geothermal plants produce power at a constant rate, without regard to weather conditions. Geothermal resources are theoretically more than adequate to supply humanity's energy needs. Most extraction occurs in areas near tectonic plate boundaries. The cost of generating geothermal power decreased by 25% during the 1980s and 1990s. Technological advances continued to reduce costs and thereby expand the amount of viable resources. In 2021, the US ...

Efficient Energy Use
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, building insulation, insulating a building allows it to use less heating and cooling energy while still maintaining a Thermal comfort, comfortable temperature. Another method made by Lev Levich is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in Green building, buildings, industrial processes and Energy efficiency in transport, transportation could reduce the world's energy needs in 2050 by one third. There are two main motivations to improve energy efficiency. Firstly, one motivation is to achieve Operating cost, cost savings during the operation of the appliance or process. However, installing an energy-efficient technology comes with an upfront cost, the ...

Lockport, New York
Lockport is both a city and the town that surrounds it in Niagara County, New York, United States. The city is the Niagara county seat, with a population of 21,165 according to 2010 census figures, and an estimated population of 20,305 as of 2019. Its name derives from a set of Erie Canal locks (Lock Numbers 34 and 35) within the city that were built to allow canal barges to traverse the of the Niagara Escarpment. It is part of the Buffalo–Niagara Falls metropolitan area. History The New York State Legislature authorized the Erie Canal's construction in April 1816. The route proposed by surveyors was to traverse an area in central Niagara County, New York, which was then "uncivilized" and free of White settlers. At the time, the nearest settlers were in nearby Cold Springs, New York. Following the announcement, land speculators began to buy large plots along and near the proposed route of the canal. By December 1820, when the exact location of the step locks had been d ...
