Advantages of Conservation of Energy

The earth's temperature is rising are result of CO2 emissions and heat into the atmosphere. It is important that we do our best to take measure to conserve energy. There are many benefits with energy conservation. Conservation of energy is an important tool to work against climate change. Energy conservation reduces emissions of greenhouse gas from fossil fuels. There are different benefits of energy conservation like lower utility bills and allows you to save the high costs of electric bills. 

Being energy efficient is doing more work using less energy; this is beneficial to you and your environment. There are many benefits from energy conservation, the most significant reasons for energy conservation or using energy in an efficient method are:
  • Energy efficiency saves money.
  • It improves the economy.
  • It is environmental friendly.
  • It improves national security.
  • It upgrades and enhances quality of life.
  • It improves indoor air quality.
Some of the Advantages of Conservation of energy are:
  • Decrease in air pollution: Burning of fossil fuels to produce energy released various gases and fine particles into the air. Uncontrolled release of these elements into the air can reduce air quality leading to air pollution and health problems. Reducing the usage of these fuels and conserving can result in better air quality and less pollution. 
  • Better health and safety: Cleaning of appliances used at home frequently can be energy efficient. This brings good indoor air quality and decreases health related issues. 
  • Money is saved:Use of energy conservation appliances for heating and lighting conserves energy and decreases the electricity bills helping you save money. 
  • Longer life span to appliances:Using energy conservation products and electronic items have a longer life span than other appliances. Thus, it can reduce the overall cost and maintenance costs. 
  • Reduces groundwater and surface water pollution: Extraction of fossil fuels and pollution contaminates the water and becomes unsuitable for consumption. Conservation of energy reduces pollution and use of fossil fuels resulting in reduced pollution of ground and surface water.
  • Reduces wildlife and land disruption: Extraction of fossil fuels and production of usable energy leads to a significant disruption to land, wildlife and natural environment. Hence, reduction in usage of fossil energy can help conserve wildlife and nature.

Conservation of energy

The law of conservation of energy is an empirical law of physics. It states that the total amount of energy in an isolated system remains constant over time (is said to be conserved over time). A consequence of this law is that energy can neither be created nor destroyed: it can only be transformed from one state to another. The only thing that can happen to energy in a closed system is that it can change form: for instance chemical energy can become kinetic energy.

Albert Einstein's theory of relativity shows that energy and mass are the same thing, and that neither one appears without the other. Thus in closed systems, both mass and energy are conserved separately, just as was understood in pre-relativistic physics. The new feature of relativistic physics is that "matter" particles (such as those constituting atoms) could be converted to non-matter forms of energy, such as light; or kinetic and potential energy (example: heat). However, this conversion does not affect the total mass of systems, because the latter forms of non-matter energy still retain their mass through any such conversion.

Today, conservation of “energy� refers to the conservation of the total system energy over time. This energy includes the energy associated with the rest mass of particles and all other forms of energy in the system. In addition, the invariant mass of systems of particles (the mass of the system as seen in its center of mass inertial frame, such as the frame in which it would need to be weighed) is also conserved over time for any single observer, and (unlike the total energy) is the same value for all observers. Therefore, in an isolated system, although matter (particles with rest mass) and "pure energy" (heat and light) can be converted to one another, both the total amount of energy and the total amount of mass of such systems remain constant over time, as seen by any single observer. If energy in any form is allowed to escape such systems (see binding energy), the mass of the system will decrease in correspondence with the loss.

A consequence of the law of energy conservation is that perpetual motion machines can only work perpetually if they deliver no energy to their surroundings.


Ancientphilosophers as far back as Thales of Miletus had inklings of the conservation of which everything is made. However, there is no particular reason to identify this with what we know today as "mass-energy" (for example, Thales thought it was water). In 1638, Galileo published his analysis of several situations—including the celebrated "interrupted pendulum"—which can be described (in modern language) as conservatively converting potential energy to kinetic energy and back again. It was Gottfried Wilhelm Leibniz during 1676–1689 who first attempted a mathematical formulation of the kind of energy which is connected with motion (kinetic energy). Leibniz noticed that in many mechanical systems (of several masses, mieach withvelocityvi),

\sum_{i} m_i v_i^2

was conserved so long as the masses did not interact. He called this quantity the vis vivaor living force of the system. The principle represents an accurate statement of the approximate conservation ofkinetic energy in situations where there is no friction. Many physicists at that time held that the conservation of momentum, which holds even in systems with friction, as defined by the momentum:

\,\!\sum_{i} m_i v_i

was the conserved vis viva. It was later shown that, under the proper conditions, both quantities are conserved simultaneously such as in elastic collisions.

It was largely engineers such as John Smeaton, Peter Ewart, Karl Hotzmann, Gustave-Adolphe Hirn and Marc Seguin who objected that conservation of momentum alone was not adequate for practical calculation and who made use of Leibniz's principle. The principle was also championed by some chemists such as William Hyde Wollaston. Academics such as John Playfair were quick to point out that kinetic energy is clearly not conserved. This is obvious to a modern analysis based on the second law of thermodynamics but in the 18th and 19th centuries, the fate of the lost energy was still unknown. Gradually it came to be suspected that the heat inevitably generated by motion under friction, was another form of vis viva. In 1783, Antoine Lavoisier and Pierre-Simon Laplace reviewed the two competing theories of vis viva and caloric theory. Count Rumford's 1798 observations of heat generation during the boring of cannons added more weight to the view that mechanical motion could be converted into heat, and (as importantly) that the conversion was quantitative and could be predicted (allowing for a universal conversion constant between kinetic energy and heat). Vis viva now started to be

Energy conservation

Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources.

Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and human comfort. Individuals and organizations that are direct consumers of energy choose to conserve energy to reduce energy costs and promote economic security. Industrial and commercial users can increase energy use efficiency to maximize profit.

Energy conservation policies

Electrical energy conservation is an important element of energy policy. Energy conservation reduces the energy consumption and energy demand per capita and thus offsets some of the growth in energy supply needed to keep up with population growth. This reduces the rise in energy costs, and can reduce the need for new power plants, and energy imports. The reduced energy demand can provide more flexibility in choosing the most preferred methods of energy production.

Climate change

By reducing emissions, energy conservation is an important part of lessening climate change. Energy conservation facilitates the replacement of non-renewable resources with renewable energy. Energy conservation is often the most economical solution to energy shortages, and is a more environmentally being alternative to increased energy production.

Energy conservation by country

The Republic of India

Petroleum Conservation Research Association (PCRA) [http://www.pcra.org www.pcra.org] is an Indian government body created in 1976 and engaged in promoting energy efficiency and conservation in every walk of life. In the recent past PCRA has done mass media campaigns in television, radio & print media. An impact assessment survey by a third party revealed that due to these mega campaigns by PCRA, overall awareness level have gone up leading to saving of fossil fuels worth crores of rupees besides reducing pollution.

Bureau of Energy Efficiency is an Indian governmental organization created in 2002 responsible for promoting energy efficiency and conservation.


Since the 1973 oil crisis, energy conservation has been an issue in Japan. All oil based fuel is imported, so indigenous sustainable energy is being developed.

The [http://www.asiaeec-col.eccj.or.jp/index.html Energy Conservation Center] promotes energy efficiency in every aspect of Japan. Private entities are implementing the efficient use of energy for industries.


In Lebanon and since 2002 The Lebanese Center for Energy Conservation (LCEC) has been promoting the development of efficient and rational uses of energy and the use of renewable energy at the consumer level. It was created as a project financed by the Global Environment Facility (GEF) and the Ministry of Energy Water (MEW) under the management of the United Nations Development Programme (UNDP) and gradually established itself as an independent technical national center although it continues to be supported by the United Nations Development Programme (UNDP) as indicated in the Memorandum of Understanding (MoU) signed between MEW and UNDP on June 18, 2007.

New Zealand

In New Zealand the Energy Efficiency and Conservation Authority is responsible for promoting energy efficiency and conservation.

European Union

At the end of 2006, the European Union-EU pledged to cut its annual consumption of primary energy by 20% by 2020. The 'European Union Energy Efficiency Action Plan' is long awaited. As part of the EU's [http://www.ademe.fr/partenaires/odyssee/pdf/save2000.pdf SAVE Programme], aimed at promoting energy efficiency and encouraging energy-saving behaviour, the Boiler Efficiency Directive specifies minimum levels of efficiency for boilers fired with liquid or gaseous fuels. The European Commission is funding large-scale research projects to learn about success factors for effective energy conservation programmes.

United Kingdom

Energy conservation in the United Kingdom has been receiving increased attention over recent years. Key factors behind this are the Government's commitment to reducing carbon emissions, the projected 'energy gap' in UK electricity generation, and the increasing reliance on imports to meet national energy needs. Domestic housing and road transport are currently the two biggest problem areas.

Responsibility for energy conservation fall between three Government departments although is led by the Department for Energy and Climate Change (DECC). The Department for Communities and Local Government (CLG) is still responsible for energy standards in buildings, and the Department for Environment, Food and Rural Affairs (Defra) retains a residual interest in energy insofar as it leads to emissions of CO2, the main greenhouse gas. The Department for Transport retains many responsibilities

Question:Curious... Any considerable pros and cons? (mostly cons.... pros are easy to indentify)

Answers:The disadvantage in conservation of energy is you getting less of it. Advantages someone else getting more of it. There is no way you can really save or conserve energy at your home or apartment. The energy plant will use same amount of coal either you turn off all your light or turn them all on. So that is big myth that you can do anything in your little place to conserve energy. Especially in any amount that could make any difference on the global scale.

Question:what are they

Answers:But there are various advocates of "conservation" who use the term to mean "in lieu of addtional energy source(s)" thus making the term equivalent to (in their minds) a source. That said, an advantage is that conservation can reduce the total demand for energy thus reducing fuel use and, potentially, delaying or negating the need for an additional generating station of whatever kind. That is an economic benefit ("advantage") if conservation is taken to mean "reduction in present usage". But some advocate the replacement of presently used appliances, lighting, hvac units, etc. with newer more efficient versions, either when needed or even prior to end-of-life. That can be a disadvantage or advantage depending upon the economic benefits. Some advocates of conservation as a means of reducing energy usage ignore economic effects. This is a disadvantage as that approach will result in a huge reduction in economic growth and therefore reducing the quality of life for all.
