Peak District
The Peak District is an Highland, upland area in central-northern England, at the southern end of the Pennines. Mostly in Derbyshire, it extends into Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire. It is subdivided into the Dark Peak, moorland dominated by gritstone, and the White Peak, a limestone area with valleys and gorges. The Dark Peak forms an arc on the north, east and west of the district, and the White Peak covers central and southern areas. The highest point is Kinder Scout (). Most of the area is within the Peak District National Park, a protected landscape designated in 1951. A 2021 report states that "the Park's own population numbers around 40,000 and supports an estimated 18,000 jobs, predominantly through farming, manufacturing and, inevitably, tourism". The area has been inhabited since the Mesolithic era; it was largely used for agricultural purposes until mining arose in the Middle Ages. During the Industrial Revolution, seve ...

Peaked Cap
A peaked cap, peaked hat, service cap, barracks cover, or combination cap is a form of headgear worn by the armed forces of many nations, as well as many uniformed civilian organisations such as law enforcement agencies and fire departments. It derives its name from its short visor, or peak, which was historically made of polished leather but increasingly is made of a cheaper synthetic substitute. The term forage cap is also used, although that also applies to the "field service cap" or the side cap. Other principal components are the crown, band, and insignia, typically a cap badge and scrambled egg (uniform), embroidery in proportion to rank. Piping is also often found, typically in contrast to the crown colour, which is usually white for navy, blue for air force, and green for army. The band is typically a dark, contrasting colour, often black, but may be patterned or striped. In the British Army, each regiment and corps has a different badge. In the United States Armed Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Oil
Peak oil is the point when global oil production reaches its maximum rate, after which it will begin to decline irreversibly. The main concern is that global transportation relies heavily on gasoline and diesel. Adoption of electric vehicles, biofuels, or more efficient transport (like trains and waterways) could help reduce oil demand. Peak oil relates closely to oil depletion; while petroleum reserves are finite, the key issue is the economic viability of extraction at current prices. Initially, it was believed that oil production would decline due to reserve depletion, but a new theory suggests that reduced oil demand could lower prices, affecting extraction costs. Demand may also decline due to persistent high prices. Over the last century, many predictions of peak oil timing have been made, often later proven incorrect due to increased extraction rates. M. King Hubbert introduced the concept in a 1956 paper, predicting U.S. production would peak between 1965 and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Coal
Use of coal is expected to peak in the mid-2020s. Historically, it was widely believed that the supply-side would eventually drive peak coal due to the depletion of coal reserves. However, since the increasing global efforts to limit climate change, peak coal has been driven by demand. This is due in large part to the rapid expansion of natural gas and renewable energy. As of 2024 over 40% of all energy sector CO2 emissions are from coal, and many countries have pledged to coal phase-out, phase-out coal. The peak of coal's share in the global energy mix was in 2008, when coal accounted for 30% of global energy production. Coal consumption is declining in the United States and Europe, as well as developed economies in Asia. However production increased in Coal in India, India, Coal in Indonesia, Indonesia and Coal in China, China, which offset the falls in other regions. Global coal consumption reached an all time high in 2023 at 8.5 billion tons, but is expected to reach a new re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Gas
Peak gas is the point in time when the maximum global natural gas (fossil gas) production rate will be reached, after which the rate of production will enter its terminal decline. Although demand is peaking in the United States and Europe, it continues to rise globally due to consumers in Asia, especially China. Natural gas is a fossil fuel formed from plant matter over the course of millions of years. Natural gas derived from fossil fuels is a non-renewable energy source; however, methane can be renewable in other forms such as biogas. Peak coal was in 2013, and peak oil is forecast to occur before peak gas. One forecast is for natural gas demand to peak in 2035. The concept of peak gas follows from Hubbert peak theory, which is most commonly associated with peak oil. Hubbert saw gas, coal and oil as natural resources, each of which would peak in production and eventually run out for a region, a country, or the world. Gas demand The world gets almost one quarter of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Car
Peak car (also peak car use or peak travel) is a hypothesis that motor vehicle distance traveled per capita, predominantly by private car, has peaked and will now fall in a sustained manner. The theory was developed as an alternative to the prevailing market saturation model, which suggested that car use would saturate and then remain reasonably constant, or to GDP-based theories which predict that traffic will increase again as the economy improves, linking recent traffic reductions to the Great Recession of 2008. The theory was proposed following reductions, which have now been observed in Australia, Belgium, France, Germany, Iceland, Japan (early 1990s), New Zealand, Sweden, the United Kingdom (many cities from about 1994) and the United States. A study by Volpe Transportation in 2013 noted that average miles driven by individuals in the United States has been declining from per month in 2004 to in July 2012, and that the decline had continued since the recent upturn in ...

Mountain Peak
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topography, topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some Topographic prominence, prominence or Topographic isolation, isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent ...

Peak Electricity Demand
Energy demand management, also known as demand-side management (DSM) or demand-side response (DSR), is the modification of consumer demand for energy through various methods such as financial incentives and behavioral change through education. Usually, the goal of demand-side management is to encourage the consumer to use less energy during peak hours, or to move the time of energy use to off-peak times such as nighttime and weekends. Peak demand management does not necessarily decrease total energy consumption, but could be expected to reduce the need for investments in networks and/or power plants for meeting peak demands. An example is the use of energy storage units to store energy during off-peak hours and discharge them during peak hours. A newer application for DSM is to aid grid operators in balancing variable generation from wind and solar units, particularly when the timing and magnitude of energy demand does not coincide with the renewable generation. Generators br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Water
Peak water is a concept that underlines the growing constraints on the availability, quality, and use of freshwater resources. Peak water was defined in 2010 by Peter Gleick and Meena Palaniappan. They distinguish between peak renewable, peak non-renewable, and peak ecological water to demonstrate the fact that although there is a vast amount of water on the planet, sustainably managed water is becoming scarce. Lester R. Brown, president of the Earth Policy Institute, wrote in 2013 that although there was extensive literature on peak oil, it was peak water that is "the real threat to our future". An assessment was published in August 2011 in the Stockholm International Water Institute's journal. Much of the world's water in underground aquifers and in lakes can be depleted and thus resembles a finite resource. The phrase ''peak water'' sparks debates similar to those about peak oil. In 2010, ''New York Times'' chose "peak water" as one of its 33 "Words of the Year". There ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Experience
A peak experience is an altered state of consciousness characterized by euphoria, often achieved by self-actualizing individuals. The concept was originally developed by psychologist Abraham Maslow in mid-1940s and term was coined by him in 1956 (see "History" below). According to T. Landsman, "Maslow described them eak experiencesas rare, exciting, oceanic, deeply moving, exhilarating, elevating experiences that generate an advanced form of perceiving reality, and are even mystic and magical in their effect upon the experimenter." There are several unique characteristics of a peak experience, but each element is perceived together in a holistic manner that creates the moment of reaching one's full potential. Peak experiences can range from simple activities to intense events; however, it is not necessarily about what the activity is, but the ecstatic, blissful feeling that is being experienced during it. History Peak experiences were originally presented by Abraham Maslow in S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Peak (Hong Kong)
Victoria Peak ( zh, t=太平山, j=taai3 ping4 saan1) is a hill on the western half of Hong Kong Island. It is also known as Mount Austin, and locally as The Peak only generally. With an elevation of , it is the tallest hill on Hong Kong Island, and the 29th tallest in the territory of Hong Kong. It is a major tourist attraction offering views of Central, Victoria Harbour, Lamma Island and the surrounding islands. The summit of Victoria Peak is occupied by a radio telecommunications facility and is closed to the public. The name ''The Peak is'' usually a reference to the surrounding area of public parks, tourist facilities and high-value residential land. ''The Peak'' also refers to Victoria Peak itself and its nearby areas, including Victoria Gap, Mount Kellett and Mount Gough. Sometimes Bowen Hill may also be included. The Peak is also known as a residential area consisting of different neighbourhoods including the less affluent Mount Kellett which faces Southside. It ...

Peak Hour
A rush hour (American English, British English) or peak hour (Australian English, Indian English) is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice every weekday: once in the morning and once in the afternoon or evening, the times during which most people commute. The term is often used for a period of peak congestion that may last for more than one hour. The term is very broad, but often refers specifically to private automobile transportation traffic, even when there is a large volume of cars on a road but not many people, or if the volume is normal but there is some disruption of speed. By analogy to vehicular traffic, the term Internet rush hour has been used to describe periods of peak data network usage, resulting in delays and slower delivery of data packets. Definition The name is sometimes a misnomer, as the peak period often lasts more than one hour and the "rush" refers t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
