Main articles: Renewable energy and Renewable energy development
One means of reducing carbon emissions is the development of new technologies, such as renewable energy. Currently governments subsidise fossil fuels by an estimated $235 billion a year.[14] However, in some countries, government action has boosted the development of renewable energy technologies—for example, a programme to put solar panels on the roofs of a million homes ...

| | | | | energy conservation: Encyclopedia II - Conservation ethic - History of biological conservation The origins of biological conservation can be traced to philosophical and religious beliefs about Man as a full part of Nature:
The Torah, or Old Testament discusses the concept of the Sabbatical Year, a period whereby the fields are left fallow, presumably in order to rejuvenate the soil. This would appear to be an ancient form of the ecological practice of crop rotation. The weekly Sabbath is also a time when beasts of burden are given rest from their work. The Torah further prohibits the destruction of fruit bearing trees, and th ...

Daylight saving time - Africa.
Egypt switches to DST on midnight of the last Thursday of April, since the weekend holiday for most Egyptians is on Friday, thus giving workers and students a chance to adjust.
Daylight saving time - Asia.
The People's Republic of China experimented with DST from 1986, but abandoned it in the 1990s. The PRC now uses one universal time zone for all of the nation from Urumqi in the northwest to Fujian in the southeast; the size of the nation was ...

Resource base of Communist Czechoslovakia - Minerals and Mining.
Czechoslovakia had significant quantities of coal and lignite.
Hard coal suitable for extraction was present in the Ostrava coalfields and near Kladno, Plzen (Pilsen), Kosice, and Trutnov.
Brown coal and lignite deposits were located around Chomutov and Most, in the Sokolov field near Karlovy Vary, at Teplice, at Ceske Budejovice, and near Modry Kamen and Handlova in Slovakia. Reserves of oil and natural gas were rather small.< ...

| | | | | | energy conservation: Encyclopedia II - Butter - Types of butter Before modern factory butter making, cream was usually collected from several milkings and was therefore several days old and somewhat fermented by the time it was made into butter. Butter made from a fermented cream is known as cultured butter. During fermentation, the cream naturally sours as bacteria convert milk sugars into lactic acid. The fermentation produces additional aroma compounds, including diacetyl, which makes for a fuller-flavored and more "buttery" tasting product.See also:Butter, Butter - Butter making, Butter - Types of butter, Butter - History, Butter - Worldwide, Butter - Storage and cooking, Butter - Health and nutrition, Butter - Notes Read more here: » Butter: Encyclopedia II - Butter - Types of butter |

| | | | | | energy conservation: Encyclopedia II - Nuclear energy policy - International use of nuclear energy (see also energy development, future energy development and renewable energy development)
Nuclear energy use has been growing steadily since the 1970s and the early 1980s. The growth slowed in the 1980s because of environmentalist opposition, high interest rates, and energy conservation prompted by the oil shock in 1973, and the energy crisis in 1979 and the accidents at Three Mile Island in 1979 and Chernobyl [1]. Several countries, especially European countries have abandoned the use of nuclear energy since then. [2]
In 2000, there were 438 commercial nuclear generat ...

| | | | | energy conservation: Encyclopedia II - Route-dependence - Spatial route-dependence If we place two observers (A and B) on opposite sides of a rotating black hole, both on the rotation plane, with the hole directly between them, and with both observers being the same height above the hole, then the effective gravitational differential between the A and B measured across the plane depends on the direction around the hole in which in which measurements are taken.
If light-signals are exchanged around one side of the hole, in the equatorial plane, where the adjacent section of event horizon i ...

| | | | | energy conservation: Encyclopedia II - Emergy - Transformity and the rationalization of quality Like the emergy concept, the concept of transformity was first introduced by Dr.D.M.Scienceman in collaboration with the late Howard T. Odum. In 1987 D.M.Scienceman proposed that the phrases, "energy quality", "energy quality factor", and "energy transformation ratio", all used by H.T.Odum, be replaced by the the word "transformity" (p. 261). This approach aims to solve a long standing issue about the relation of qualitative phenomena to quantitative phenomena often analysed in the physical sciences, which in turn is a synthesis of rationalism wi ...

| | | | | energy conservation: Encyclopedia II - Bicycle - Technical aspects
Bicycle - Legal requirements.
The 1968 Vienna Convention on Road Traffic considers a bicycle to be a vehicle, and a person controlling a bicycle is considered a driver. The traffic codes of many countries reflect these definitions and demand that a bicycle satisfy certain legal requirements, including licencing, before it can be used on public roads. In many jurisdictions it is an offence to use a bicycle that is not in roadworthy condition and which does not have functioning front and rear brakes. In some places ...

| | | | | | energy conservation: Encyclopedia II - Nuclear energy policy - Nuclear power phase-out A Nuclear power phase-out was introduced in Sweden (1980), in Italy (1987), in Belgium (1999), and in Germany (2000) and has been discussed in several other European countries. Austria, the Netherlands, Poland, and Spain have enacted laws not to build new nuclear power stations.
One idea behind a nuclear phase-out is to force a shift to renewable energy, because of environmental concerns with electricity generation, socia ...

| | | | | energy conservation: Encyclopedia II - Schoolhouse Rock! - Factual Trivia The short "The Preamble," set to highly infectious music, has a slightly abridged wording of the Preamble of the United States Constitution. The song starts, "We the people, in order to form a more perfect union...", but the actual document starts, "We the people of the United States, in order to form a more perfect union...."
Along the same lines; a more complete definition of a noun is that it's the name of a person, place, thing, "or idea". Or more completely, that it's the name or title of any object or idea. Love and fear are not thing ...

Nuclear energy policy - Arguments against nuclear energy.
Anti-nuclear politicians state environmental concerns with nuclear power as arguments for a phase-out. A main concern against the use of nuclear power for energy production is primarily safety of the environment and people. Activists refer to nuclear accidents in the past that have released large amounts of radioactive contamination killing and hurting many people and rendering large amounts of land unusable ...

| | | | | energy conservation: Encyclopedia II - Stress-energy tensor - The various stress-energy tensors There are a number of inequivalent stress-energy tensors out there.
Stress-energy tensor - Canonical stress-energy tensor.
This is the Noether current associated with spacetime translations. In flat spacetime, this isn't symmetric in general and if we have some gauge theory, it won't be gauge invariant because space-dependent gauge transformations obviously don't commute with spatial translations. In general relativity, the translations are with respect to the coordinate system and as such, don't transform covariantly. This is called a pseudostress-energy tensor.
