Negawatt
A negawatt market is a proposed idea of implementation of the demand response (Grid balancing, balancing the electrical grid through the changes in consumption) that uses an energy market where the commodity traded is a ''negawatt-hour'', a unit of energy saved as a direct result of energy conservation measures. Negawatt power is investment to reduce electricity consumption rather than investing to increase supply capacity. In this way investing in negawatts can be considered as an alternative to a new power station and the costs and environmental concerns can be compared. Negawatt investment alternatives to reduce consumption by improving efficiency include: * Improved thermal insulation and airtightness for buildings – low environmental impact * Replacing older industrial plant – low environmental impact. Can have a positive impact due to reduced emissions. Negawatt investment alternatives to reduce peak electrical load by time shifting demand include: * Storage heaters ...

Amory Lovins
Amory Bloch Lovins (born November 13, 1947) is an American writer, physicist, and former chairman/chief scientist of the Rocky Mountain Institute. He has written on energy policy and related areas for four decades, and served on the US National Petroleum Council, an oil industry lobbying group, from 2011 to 2018. Lovins has promoted energy efficiency, the use of renewable energy sources, and the generation of energy at or near the site where the energy is actually used. Lovins has also advocated a "negawatt revolution" arguing that utility customers don't want kilowatt-hours of electricity; they want energy services. In the 1990s, his work with Rocky Mountain Institute included the design of an ultra-efficient automobile, the Hypercar. He has provided expert testimony and published 31 books, including ''Reinventing Fire'', ''Winning the Oil Endgame'', '' Small is Profitable'', ''Brittle Power'', and ''Natural Capitalism''. Early life and education Lovins was born in Washing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demand Response
Demand response is a change in the power consumption of an electric utility customer to better match the demand for power with the supply. Until the 21st century decrease in the cost of pumped storage and batteries electric energy could not be easily stored, so utilities have traditionally matched demand and supply by throttling the production rate of their power plants, taking generating units on or off line, or importing power from other utilities. There are limits to what can be achieved on the supply side, because some generating units can take a long time to come up to full power, some units may be very expensive to operate, and demand can at times be greater than the capacity of all the available power plants put together. Demand response seeks to adjust the demand for power instead of adjusting the supply. Utilities may signal demand requests to their customers in a variety of ways, including simple off-peak metering, in which power is cheaper at certain times of the day ...

Association NégaWatt
Association négaWatt is a French advocacy group based in Valence, Drôme. It was founded in 2001 to promote the negawatt concept and its application to French society. The association seeks to reduce the use of fossil fuels and nuclear power. Its approach is based on energy conservation, energy efficiency and the use of renewable energies. It published a scenario that details a path to phasing out these energy sources. The association unites energy specialists in France, relying mostly on volunteer engineers. Other specialists include volunteer sociologists, economists and urban planners, who work together to create energy transition scenarios and to suggest political steps that would need to be taken. Association négaWatt inspired local initiatives in transition towns called "Virage-Énergie," meaning "energy bend". NégaWatt scenario The NégaWatt scenario spans from 2012 to 2050. The scenario starts by assessing energy needs for heating, transportation and specific elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Time Value Of Money
The time value of money is the widely accepted conjecture that there is greater benefit to receiving a sum of money now rather than an identical sum later. It may be seen as an implication of the later-developed concept of time preference. The time value of money is among the factors considered when weighing the opportunity costs of spending rather than saving or investing money. As such, it is among the reasons why interest is paid or earned: interest, whether it is on a bank deposit or debt, compensates the depositor or lender for the loss of their use of their money. Investors are willing to forgo spending their money now only if they expect a favorable net return on their investment in the future, such that the increased value to be available later is sufficiently high to offset both the preference to spending money now and inflation (if present); see required rate of return. History The Talmud (~500 CE) recognizes the time value of money. In Tractate Makkos page 3a the Ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecological Footprint
The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment. Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has ...

Paradigm Shift
A paradigm shift, a concept brought into the common lexicon by the American physicist and philosopher Thomas Kuhn, is a fundamental change in the basic concepts and experimental practices of a scientific discipline. Even though Kuhn restricted the use of the term to the natural sciences, the concept of a paradigm shift has also been used in numerous non-scientific contexts to describe a profound change in a fundamental model or perception of events. Kuhn presented his notion of a paradigm shift in his influential book ''The Structure of Scientific Revolutions'' (1962). Kuhn contrasts paradigm shifts, which characterize a Scientific Revolution, to the activity of normal science, which he describes as scientific work done within a prevailing framework or paradigm. Paradigm shifts arise when the dominant paradigm under which normal science operates is rendered incompatible with new phenomena, facilitating the adoption of a new theory or paradigm. As one commentator summarizes: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Market
The secondary market, also called the aftermarket and follow on public offering, is the financial market in which previously issued financial instruments such as stock, bonds, options, and futures are bought and sold. The initial sale of the security by the issuer to a purchaser, who pays proceeds to the issuer, is the primary market. All sales after the initial sale of the security are sales in the secondary market. Whereas the term primary market refers to the market for new issues of securities, and " market is primary if the proceeds of sales go to the issuer of the securities sold," the secondary market in contrast is the market created by the later trading of such securities. With primary issuances of securities or financial instruments (the primary market), often an underwriter purchases these securities directly from issuers, such as corporations issuing shares in an IPO or private placement. Then the underwriter re-sells the securities to other buyers, in what is r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Efficient Energy Use
Efficient energy use, sometimes simply called energy efficiency, is the process of reducing the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs, fluorescent lighting, or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process or by application of commonly accepted methods to reduce energy losses. There are many motivations to improve energy efficiency. Decreasing energy use reduces energy costs and may result in a financial cost saving to consumers if the energy savings offset any additional costs of implementing an energy-efficient technology. Reducing energy use is also seen as a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecticut
Connecticut () is the southernmost state in the New England region of the Northeastern United States. It is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Its capital is Hartford and its most populous city is Bridgeport. Historically the state is part of New England as well as the tri-state area with New York and New Jersey. The state is named for the Connecticut River which approximately bisects the state. The word "Connecticut" is derived from various anglicized spellings of "Quinnetuket”, a Mohegan-Pequot word for "long tidal river". Connecticut's first European settlers were Dutchmen who established a small, short-lived settlement called House of Hope in Hartford at the confluence of the Park and Connecticut Rivers. Half of Connecticut was initially claimed by the Dutch colony New Netherland, which included much of the land between the Connecticut and Delaware Rivers, although the firs ...
