A goal of reducing national energy expenditure, if pursued rigorously, can lead to a strong emphasis on energy efficiency, improve economic competitiveness, and limit oil dependence. A policy of Polluter pays must be adopted. In effect, this means specific disincentives are required to ensure that industries do not become too heavily dependent on fossil fuels that threaten life-support systems. A beginning is being made by Government of India to give the same type of resources and support to developing alternative sources of energy as have so far been extended to the development of conventional energy sources.
The latter, as experience has shown, pose a great danger to the environment. Many environmentally safe alternatives have been found today, which await encouragement from the Government for proper exploitation.

Then put the pan on the burner that fits it best. Remember that smaller burners use less electricity. Every type of heating element on an electric cook-top coils, solid disk elements and radiant elements under ceramic glass works more efficiently when the bottom of the pan is flat.
Convection ovens are more energy-efficient than standard ovens. They continuously circulate heat around the food which distributes the heat more evenly so temperatures and cooking time can be decreased. In fact, the most efficient pan has a slightly concave bottom, which flattens out when the metal heats up.
The more rounded or warped the pan, the less direct contact it has with the burner so the harder the element has to work to heat up the pan. The flame on your gas burner should be blue. A yellow flame means the gas is not burning efficiently. Call the gas company to check it. Using glass or ceramic pans in the oven allows turning down the temperature about 25 degrees Fahrenheit and still cook the food in the same amount of time.
When immersion rods are used, switch off when water is heated to the required level. Cover the container with a lid to avoid wastage. Periodical inspection of wiring may be done to defect leakage if any.
Use Earth leakage circuit breakers. Think about what you want before you reach for the door. Get in the habit of keeping items in the same place in the fridge e. Make sure foods are covered before they are kept in the refrigerator. Otherwise the moisture in them will evaporate, which makes the refrigerator use more energy. Let foods cool before they are put into the refrigerator or freezer. Freezer works more efficiently when full than when nearly empty, so put some plastic containers like old milk jugs with water in them in the freezer to take up empty space.
Similar to the energy conservation opportunities and measures applicable in the domestic house, we can save substantial amount of electrical energy by adopting simple techniques or measures in the office as well.
Most of the energy consumed in the office is in the form of electrical energy for lighting, running ACs, operating office equipment etc. Energy can be saved by optimizing the use of these equipment and using energy efficient technologies.
Also the design of office building plays on important role in energy conservation. CFLs use only one-fourth the energy and last up to 10 times longer. Switch off all unnecessary lights. Use dimmers, motion sensors or occupancy sensors to automatically turn off lighting when not in use to reduce energy use and costs.
Use task lighting; instead of brightly lighting an entire room, focus the light where you need it, to directly illuminate work areas. Close or adjust window blinds to block direct sunlight to reduce cooling needs during warm months. Overhangs or exterior window covers are most effective to block sunlight on south facing windows.
In the winter months, open blinds on south-facing windows during the day to allow sunlight to naturally heat your workspace. At night, close the blinds to reduce heat loss at night. Unplug equipment that drains energy when not in use i. Turn off your computer and monitors at the end of the work day, if possible. If you leave your desk for an extended time, turn off your monitor.
Turn off photocopier at night or purchase a new copier with low standby feature. Purchase printers and fax machines with power management features and itself. Photocopy only what you need.
Always use the second side of paper, either by printing on both sides or using the blank side as scrap paper. Collect your utility bills: Separate electricity and fuel bills. Target the largest energy consumer or the largest bill for energy conservation measures. These above mentioned energy conservation measures when adopted can brought drastic reduction in the energy bill for the office. In the previous section, we have seen the energy conservation needs and various strategies which can be applied to achieve energy savings in domestic sector.
As we know in the domestic sector buildings are involved. Similar strategies or mechanism can be applied to commercial buildings such as organisation building or office building etc. There is a huge potential of energy savings in buildings of an organisation of office as we have discussed in energy saving measures for domestic sector earlier.
Everyone knows that saving energy is a good thing, but most people will only be motivated when we can demonstrate just how much energy they are wasting and just how much potential there is for them to improve. Essentially you need to raise the energy awareness of all concerned in an organisation and for this; you need an energy-awareness campaign.
Now, typical preparation for an energy-awareness campaign might begin with a hunt for generic poster facts and figures and generic pictures of light switches, children hugging trees and polar bears on melting ice caps etc.
But the problem with that approach is that most people have seen it all many times before and consequently they rarely stop to think about the underlying message. The usual array of eliched poster facts and figures is not nearly as effective as targeted facts and figures that are specific to your organisation and that you easily come up with yourself. The knock-on effects of us using it e. When your concept of energy awareness is closer to home, your campaign will naturally use messages, facts and figures that are closer to home too.
The more you can relate your facts and figures to the day-to-day actions of your staff, the more likely they will be to take action.
So, instead of using global statistics or natural statistics or city-level statistics in your campaign, use statistics that are directly relevant to energy consumption at your organisation. Or, even better, use statistics that are directly relevant to energy consumption in your building. Or, even better still, use statistics that are directly relevant to energy consumption on your floor of the building, or in your particular department.
Armed with this knowledge, your task of raising energy awareness amongst staff will be much easier, as you will be able to highlight the wastage that they are responsible for and encourage them with evidence of the savings that they have made. For this you need good data. First things first, unless you have good quality energy data, you will struggle to get really useful figures. Weekly or monthly meter readings will never be able to tell you how much energy your building is using at different times throughout each day and on the different days of the week — this level of detail really is necessary to calculate the focused personalized figures that can have the biggest impact on the energy awareness of your staff.
Hopefully you will already have access to interval data such as 15 minute or half-hours data — if not, you may want to look into getting smart metering fitted in your building. The figures you need will come from analysis of your energy-consumption data. The first thing to do is to look at your patterns of energy consumption to find energy waste. Once you have found energy waste, you should be able to quantify it in terms of how much energy is actually being wasted.
Start by estimating the wasted kWh and then multiple those figures by cost-per-kWh and kg- CO 2 -per-kWh figures to get the equivalent cost and CO 2 figures or if you want to highlight waste as a percentage of some sort, simply look at the percentage differences between the kW or kWh figures from the appropriate time periods, buildings floors or departments that you want to compare.
Specific figures are generally best for raising energy awareness amongst staff. Use your imagination a little — may be look at energy consumption on weekends or during lunch hours. If your building operates continuously every day, investigate the energy consumption of different shifts. All of this information will be contained within your detailed interval energy data.
You just need to extract it and present it in an accessible format. The best results by far will be achieved if you treat your energy-awareness campaign as an ongoing process. The patterns or profiles of energy usage contained within interval energy data are great for discovering where a building is wasting energy. The fine-grained detail of interval data such as half-hourly data is key — daily, weekly or monthly data does not carry anywhere near as much information about how energy is being used.
Looking at energy profiles to find energy waste requires you to have some knowledge of the way that the building is operated. The key is to try to link the patterns of energy usage with the operations of the building.
Energy profiles show how much energy is being used at particular times-of- the-day and days-of-the-week — you want to be able to have a pretty good idea of what equipment is using that energy and why it needs to be using it at the times in question.
To make sense of the energy profiles, you need to have good idea about what goes on in the building. Not everything that goes on in the building, just the things that relate to energy consumption. Every building is different, but the following factors are commonly relevant.
What are the core occupancy hours e. Are there multiple shifts e. Do people ever work on-site outside of the core occupancy hours? Do certain staff stay on after the official closing time?
Does anyone come in on weekends or holidays? Is there air conditioning? Is it used just for cooling in summer or is it used all year round e. How is the heating controlled? Is it on a timer? When is it set to switch on and off? Are there different timer settings for weekends and holidays? This is particularly significant in cost terms because electricity usually costs several times more per kWh than gas. Air-conditioning also usually consumes a lot of electricity. It indicates that HVAC energy wastage can usually be identified from patterns of electricity consumption alone.
What controls when the lights come on and off? Are they automatically controlled e. Are there enough light-switches? For example, if one person is working late in a large open office, will they have to light the entire office just to light their desk? Most buildings have different sets of lights for different purposes e.
This could include anything from a printing room, to a fork-lift-truck charger, to specialist production-line equipment. When do they use energy? When do the processes run? Firstly, for the sake of earths continued existence, people should take responsibility for their energy consumption. People can save energy by turning off appliances, TV and radio that are not being used, watched or listened to. For example, switching off the light when no one is in the room.
People should use human power instead using a food processor. For instance, wash the dishes by hand instead of running the dishwasher.
Let the hair dry in the sun instead of using the hair dryer. Also, raising or reducing a degree of room temperature in summer or winter and extending the period of the daylight savings time are some of the ways to save energy in our daily lives.
Energy conservation is a very important part of energy planning and its management. It not only saves energy resources for future, avoids wasteful utilisation of energy, provides solution to energy crisis and ensures higher per capita availability/ consumption but controls environmental degradation and pollution.
Energy supplies can be extended by the conservation, or planned management, of currently available resources. There are three types of energy conservation practices. The first is curtailment; doing without. For instance, cutting back on travel to reduce the amount of gasoline burned.
Energy Conservation: It is the practice of reducing the quantity of energy used. It may be attained through efficient energy use; in this case, energy use is decreased at the same time getting a same outcome as a result, or by reduced consumption of energy services. Commercial energy accounts for a little over half of the total energy used in the country, the rest coming from non-commercial sources. Share of agriculture in commercial energy consumption has risen rapidly over the past two-and-a-half decades.
Energy Conservation. Energy is considered as the capacity of a physical system to perform or complete work whether through a mental or physical state. On the other hand, energy can also include the physical movements such as the shifting of something from a given place to . - The Conservation of Energy Physics Essay: The Conservation of Energy Since the beginning of time, energy has pervaded our earth. These days we rely on it to advance in our technological developments.
