“If you wish to bear fruits you must go to your roots.”
The core question arises in our mind that society lies in the roots of 3E (Energy, Economy, and Environment). Society needs to keep all energy options open to satisfy the growing demand. The industrial and consumer flow of energy and their effects on the environment is higher. They influence the economic, political, regulatory, and social factors of the country. So that the economy of the country is directly rely on the transformation and utilization of resources.
The energy sources are primarily carbon-based fuels, hydro and nuclear power. Because of their cost, performance, availability and use, fossil fuels will remain a dominant energy source, along with nuclear and hydro. The other renewable energy sources such as wind and solar power, biomass energy and are likely to grow significantly in importance. We have to create awareness about energy conservation and their role in the economic growth and the environment using the T.E.A.M approach (Teach, Enforce, Advocate, Model). Shifting our focus to industrial ecosystems for better status of Energy – Economy – Environment. So our target is to maximize energy efficiency by reducing environmental wastes. Having concern for the environmental impacts of energy developments by identifying the opportunities for reducing carbon emissions and promoting sustainable manufacturing growth and practices and reduction of business costs by developing economic new sources of supply and innovative technologies, developing the delivery infrastructure to meet changes in demand and supply, improving energy efficiency and finally reliability in production, delivery, and customer end use.
We should directly focus on industrial ecosystem to attain the benefits of complete energy- economy – environment. The progress toward environmental and economic goals is achieved by meeting environmental and economic goals and by achieving organizational carbon reduction. There will be a significant cost savings result from increased process efficiencies and reduced waste and profitable sustainability practices. Enabling frameworks for energy efficiency, utilizing market forces, promoting open trade and investment, avoiding trade-restrictive measures, fostering research, development and deployment of energy efficient technologies, emphasizing international cooperation, encouraging mutual recognition of voluntary energy labels and standards, integrating efficiency with climate change, security, access and other aspects of energy policy, and finally by developing and utilizing rigorous and reliable metrics, and life-cycle oriented approaches.
The Waste water Treatment, reduces the Environmental Impact. Commonly the sludge on a yearly basis of newspaper, bio and natural waste, agricultural refuse, concrete and metal waste can be resold after cleaning for recycling. Thus introducing the industrial ecosystem in India will result in drastic effect in the form of the 3E’s. The forecasting results are economic, environmental savings of energy sources, coal and water, reduced emissions of CO2, SO2, NO2 and finally reuse of waste products (fly ash, sulfur, gypsum, nitrogen in sludge). The monetary benefits are realised from the production costs (purchasing unwanted by-products from others at bargain prices; selling its own by-products), Energy consumption (less transportation), waste management (on-site, or even being able to sell what would otherwise be waste) and finally by costs of compliance and cost of some R&D (shared with other companies).The Societal benefits are better health, more jobs, cleaner air and water and healthy economy etc. Always industrial ecosystem paves the way for sustainable development.
Clean energy options should be developed by reducing the nationwide carbon-dioxide emission, increasing the share of low carbon energy in electricity generation systems and by securing stable energy supply by building a secure energy supply system to meet economic development goals. The framework structure consists of cleaner energy supply and energy demand. The cleaner energy supplies can be fulfilled by restructuring energy mix and improve energy efficiency, developing carbon-free renewable energy and effectively explore its power generating potential. We can also increase the utilization of low carbon natural gas and energy supply diversity and by accelerating the replacement of existing power generating units and formulating a power plant efficiency improvement program to require new built units to apply the best available technology. Introduce clean coal technology to reduce the Carbon-dioxide emission of power generating system. The energy audit is the important step in improving the energy efficiency of a home or building. Audit usually identify and highlighting the energy consumption and energy wastage by organizing resources and data requirement and developing action plan to save the quality and cost. The major steps in the audit are gathering information, description of equipment/plant specification/data collecting hours/day operation, energy consumption per day, and their operational schedule.
Thus for energy, economy and environmental growth results in enhancing competitiveness for the global evolution towards a more sustainable energy future.
“Save energy today, bright life tomorrow”
“A little energy care makes demand rare”
Improving energy consumption and transformation efficiency, increasing the value added of energy consumption by adopting energy supply methods and consumption practices that ensure low carbon and low pollution. Thus there should be a Low dependence on fossil fuels and imported energy. We are in the position of cat on the wall. The real question is not “What is the policy that will answer all our environmental energy and economy problems?”, but rather “Which combination of changes, costs and risks do we want to accept?” This question is vital and urgent, as it will affect our lives and our environment for generations to come. Thus our goal is to identify clear energy action plans that are needed for the economic and environmental growth measures that will work with markets to improve information and lower barriers to deployment of economic solutions. Business supports energy efficiency and given the right way and regulatory frameworks can help governments achieve the triple objectives of energy, economy and environmental improvement.

This article is about sustainable energy usen.. For the law of conservation of energy in physics., see Conservation of energy.
Energy conservation are efforts made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of services used (for example, by driving less). Energy conservation is a part of the concept of eco-sufficiency. Energy conservation reduces the need for energy services, and can result in increased environmental quality, national security, personal financial security and higher savings. It is at the top of the sustainable energy hierarchy. It also lowers energy costs by preventing future resource depletion.
Energy can be conserved by reducing wastage and losses, improving efficiency through technological upgradation and improved operation and maintenance.
Some countries employ energy or carbon taxes to motivate energy users to reduce their consumption. Carbon taxes can allow consumption to shift to nuclear power and other alternatives that carry a different set of environmental side effects and limitations. Meanwhile, taxes on all energy consumption stand to reduce energy use across the board, while reducing a broader array of environmental consequences arising from energy production. The State of California employs a tiered energy tax whereby every consumer receives a baseline energy allowance that carries a low tax. As usage increases above that baseline, the tax is increasing drastically. Such programs aim to protect poorer households while creating a larger tax burden for high energy consumers. 7D
One of the primary ways to improve energy conservation in buildings is to use an energy audit. An energy audit is an inspection and analysis of energy use and flows for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s). This is normally accomplished by trained professionals and can be part of some of the national programs discussed above. In addition, recent development of smartphone apps enable homeowners to complete relatively sophisticated energy audits themselves.
Building technologies and smart meters can allow energy users, business and residential, to see graphically the impact their energy use can have in their workplace or homes. Advanced real-time energy metering is able to help people save energy by their actions.
In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design or climatic design because, unlike active solar heating systems, it doesn't involve the use of mechanical and electrical devices.
The key to designing a passive solar building is to best take advantage of the local climate. Elements to be considered include window placement and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be retrofitted.
In the United States, suburban infrastructure evolved during an age of relatively easy access to fossil fuels, which has led to transportation-dependent systems of living. Zoning reforms that allow greater urban density as well as designs for walking and bicycling can greatly reduce energy consumed for transportation. The use of telecommuting by major corporations is a significant opportunity to conserve energy, as many Americans now work in service jobs that enable them to work from home instead of commuting to work each day.
Consumers are often poorly informed of the savings of energy efficient products. A prominent example of this is the energy savings that can be made by replacing an incandescent light bulb with a more modern alternative. When purchasing light bulbs, many consumers opt for cheap incandescent bulbs, failing to take into account their higher energy costs and lower lifespans when compared to modern compact fluorescent and LED bulbs. Although these energy-efficient alternatives have a higher upfront cost, their long lifespan and low energy use can save consumers a considerable amount of money. The price of LEDs has also been steadily decreasing in the past five years, due to improvement of the semiconductor technology. Many LED bulbs on the market qualify for utility rebates that further reduce the price of purchase to the consumer. Estimates by the U.S. Department of Energy state that widespread adoption of LED lighting over the next 20 years could result in about $265 billion worth of savings in United States energy costs.
The research one must put into conserving energy is often too time consuming and costly for the average consumer, when there are cheaper products and technology available using today's fossil fuels. Some governments and NGOs are attempting to reduce this complexity with ecolabels that make differences in energy efficiency easy to research while shopping.
To provide the kind of information and support people need to invest money, time and effort in energy conservation, it is important to understand and link to people's topical concerns. For instance, some retailers argue that bright lighting stimulates purchasing. However, health studies have demonstrated that headache, stress, blood pressure, fatigue and worker error all generally increase with the common over-illumination present in many workplace and retail settings. It has been shown that natural daylighting increases productivity levels of workers, while reducing energy consumption
In warm climates where air conditioning is used, any household device that gives off heat will result in a larger load on the cooling system. Items such as a stove, dish washer, clothes dryer, hot water and incandescent lighting all add heat to the home. Low power or insulated versions of these devices give off less heat for the air conditioning to remove. The air conditioning system can also improve in efficiency by using a heat sink that is cooler than the standard air heat exchanger such as geothermal or water.
In cold climates heating air and water is a major demand on household energy use. By investing in newer technologies in the home, significant energy reductions are possible. Heat pumps are a more efficient alternative to using electrical resistance heaters for warming air or water. A variety of efficient clothes dryers are available, and the classic clothes line requires no energy, only time. Natural gas condensing boilers and hot air furnaces increase efficiency over standard hot flue models. New construction implementing heat exchangers can capture heat from waste water or exhaust air in bathrooms, laundry and kitchens.
In both warm and cold climate extremes, airtight thermal insulated construction will largely determine the efficiency of a home. Insulation is added to minimize the flow of heat to or from the home, but can be labor-intensive to retrofit to an existing home.
Energy conservation by the countries
Despite the vital role energy efficiency is envisaged to play in cost-effectively cutting energy demand, only a small part of its economic potential is exploited in the Asia. Governments have implemented a range of subsidies such as cash grants, cheap credit, tax exemptions, and co-financing with public-sector funds to encourage a range of energy-efficiency initiatives across several sectors. Governments in the Asia-Pacific region have implemented a range of information provision and labeling programs for buildings, appliances, and the transportation and industrial sectors. Information programs can simply provide data, such as fuel-economy labels, or actively seek to encourage behavioral changes, such as Japan's Cool Biz campaign that encourages setting air conditioners at 28-degrees Celsius and allowing employees to dress casually in the summer.
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. Directive 2012/27/EU is on energy efficiency.
As part of the EU's 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.
Petroleum Conservation Research Association (PCRA) is an Indian government body created in 1977 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(Indian currency) besides reducing pollution.
Bureau of Energy Efficiency is an Indian governmental organization created in 2001 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 Energy Conservation Center promotes energy efficiency in every aspect of Japan. Public entities are implementing the efficient use of energy for industries and research. It includes projects such as the Top Runner Program. In this project, new appliances are regularly tested on efficiency, and the most efficient ones are made the standard.
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 International 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 18 June 2007.
Until recently, Nepal has been focusing on the exploitation of its huge water resources to produce hydro power. Demand side management and energy conservation was not in the focus of government action. In 2009, bilateral Development Cooperation between Nepal and the Federal Republic of Germany, has agreed upon the joint implementation of "Nepal Energy Efficiency Programme". The lead executing agencies for the implementation are the Water and Energy Commission Secretariat (WECS). The aim of the programme is the promotion of energy efficiency in policy making, in rural and urban households as well as in the industry. Due to the lack of a government organization that promotes energy efficiency in the country, the Federation of Nepalese Chambers of Commerce and Industry (FNCCI) has established the Energy Efficiency Centre under his roof to promote energy conservation in the private sector. The Energy Efficiency Centre is a non-profit initiative that is offering energy auditing services to the industries. The Centre is also supported by Nepal Energy Efficiency Programme of Deutsche Gesellschaft für Internationale Zusammenarbeit. A study conducted in 2012 found out that Nepalese industries could save 160,000 Megawatt hours of electricity and 8,000 Terajoule of thermal energy (like diesel, furnace oil and coal) every year. These savings are equivalent to annual energy cost cut of up to 6.4 Billion Nepalese Rupees. As a result of Nepal Economic Forum 2014, an economic reform agenda in the priority sectors was declared focusing on energy conservation among others. In the energy reform agenda the government of Nepal gave the commitment to introduce incentive packages in the budget of the fiscal year 2015/16 for industries that practices energy efficiency or use efficient technologies (incl. cogeneration).
In Nigeria, the Lagos State Government is encouraging Lagosians to imbibe an energy conservation culture. The Lagos State Electricity Board (LSEB) is spearheading an initiative tagged "Conserve Energy, Save Money" under the Ministry of Energy and Mineral Resources. The initiative is designed to sensitize Lagosians around the theme of energy conservation by connecting with and influencing their behavior through do-it-yourself tips and exciting interaction with prominent personalities. In September 2013, Governor Babatunde Raji Fashola of Lagos State and rapper Jude 'MI' Abaga (campaign ambassador)() participated in the Governor's first ever Google+ Hangout on the topic of energy conservation.
In addition to the hangout, during the month of October (the official energy conservation month in the state), LSEB hosted experience centers in malls around Lagos State where members of the public were encouraged to calculate their current household energy consumption and discover ways to save money using the 1st-ever consumer-focused energy app in sub-saharan Africa. To get Lagosians started on energy conservation, Solar Lamps and Phillips Energy-saving bulbs were also given out at each experience center. Pictures from the experience centers: (part of Lagos state government energy initiatives)
Sri Lanka currently consumes fossil fuels, hydro power, wind power, solar power and dendro power for their day to day power generation. The Sri Lanka Sustainable Energy Authority is playing a major role regarding energy management and energy conservation. Today, most of the industries are requested to reduce their energy consumption by using renewable energy sources and optimizing their energy usage.
Turkey aims to decrease by at least 20% the amount of energy consumed per GDP of Turkey by the year 2023 (energy intensity).
Main article: Energy conservation in the United States
The United States is currently the second largest single consumer of energy, following China. The U.S. Department of Energy categorizes national energy use in four broad sectors: transportation, residential, commercial, and industrial.
Energy usage in transportation and residential sectors, about half of U.S. energy consumption, is largely controlled by individual consumers. Commercial and industrial energy expenditures are determined by businesses entities and other facility managers. National energy policy has a significant effect on energy usage across all four sectors.
Another aspect of energy conversation is using Leadership in Energy and Environmental Design. (LEED) This program is not mandatory, it is voluntary. This program has many categories, Energy and Atmosphere Prerequisite, applies to energy conservation. This section focuses on energy performance, renewable energy, energy performance, and many more. This program is designed to promote energy efficiency and be a green building, which is part of conservation. As mention above “energy conservation are efforts made to reduce the consumption of energy.”
