How do you distinguish between Energy Conservation and Energy Management?

Seemingly opposite to each other but objectively the same job. A proper energy management saves energy and thus conserves the natural resources by reducing their rate of decay. After all we need energy also.

Recycling IS self sustaining and successful less energy is energy used to recycle than manufacturing a new product. It has been proven so that the energy used for recycling is 1/3 of that when manufacturiung something new. Also reducing the amount of natural recources taken from our earth can help make recycling programs reach thier attainable goal of inevitably reducing emmissions and improving the state of the environment.

In any machine there is a way to put the energy inside and there is a way to take the energy out.The out put energy need not be the same type of  input energy.\nIn any machine as per conservation of energy the input and out put energies  must be equal.\n But what we speak of efficiency of a machine is the ratio of the useful out put energy to the input energy.\nNaturally this will be less than  the total out put energy. It follows efficiency is less than 100%.\nBut we can try our best to reduce the unused energy (not used for our purpose)to be the minimum possible.\n\nFor example in machines due to friction many energy is being lost as the parts are heated. But with out friction no parts will work. So  some minimum amount of energy has to be wasted (wasted according to us and not according to nature). \nA car rolls down the road because of friction and the same friction reduces efficiency. \nThe efficiency of an incandesant bulb is low because the useful  light energy is low compared to the input electical energy and most of the energy is wasted as heat energy.\nThe florescent bulb has high efficiecy compared to the ordinary bulb because less amount of energy is not used for our purpose.

Energy comes in many forms, right? Electrical, kinetic, potential, heat, chemical etc. And energy can be converted between these forms right? i.e. when you drop something from a height, potential energy is converted into kinetic energy. Same thing when you release a compressed spring. \n\nThe quality of energy refers to the ease with which you can harness it for use and conversion to other forms. For example the energy stored in a battery is high quality energy, since it's easy to harness for use. The ambient heat energy in a room, on the otherhand, is low quality energy, since it not easy or practical to extract the energy for use.

To save energy/power/electricity:\n\nShut your computer down if you will not use it for more than 3 hours. Put it in hibernate mode if it will be idle for just a couple of hours. If you will be gone for several minutes, just turn off the monitor (physically) if you are using a desktop PC. If you are using a laptop, make sure that you have set the power options in control panel to turn off h/d and monitor when not in use for a specific number minutes depending on how long you want. Ultimately, to really save energy, only turn-on your PC if you intend to use it.\n\nBy the way Logging-off is a security feature and not a power saving feature. So it does not save energy.

Mechanical energy is one of several forms of energy. It is distinguished by the property that it can be transferred from one system to another by forces known to Newtonian mechanics, and includes kinetic energy and potential energy. The conservation of mechanical energy is a principle which states that, under certain conditions, the total mechanical energy of a system is constant.

Probably you would not notice much of a difference. In fact if you used electric heat you wouln't notice any difference at all (at least in the winter). The reason is the amount of electricity an appliance uses is pretty much proportional to the amount of heat it generates. If you really want to save electricity get rid of your oven, refrigerator, toaster, hair dryer, basically any appliance which generates a lot of heat.

Although the term "energy budget" is widely used, the flow of energy in and out of the Earth is actually measured in units of power (watts), not units of energy (joules). Therefore, "power budget" would be a more accurate term.\n\nWell, ideally, the Earth's Energy Budget should have been at equillibrium; but due to the effect of Greenhouse gases, deforestation, Ozone leakage, etc. the equilibrium has already been disbalanced and the net Earth's energy content is increasing steadily. Added to this grave problem are the Solar Storms, which are increasing in number and intensity; increased amount of meteor shower; increase in the sun's radiation, etc. are calling for the end of life in our Solar system.

Well, 1st thing, how much energy you want to put into it?

Many people are often confused about power and energy.\nLet's start from the beginning, with some basic equations:\n\nEnergy = Force * distance\n\nFor a mass m moving at a speed v, the energy E is:\n\nE = 0.5 * m * v * v\n\nEnergy can be measured in Joules (J) or British Thermal units (BTU). 1 BTU is equal to roughly 1055 Joules. If a 2100 pound car is travelling at 60miles/hour, the energy is about 342600 Joules or 325 BTUs. This is the same amount of energy required to accelerate the car from 0 to 60 miles/hour on level pavement. This is independent of acceleration, it doesn't matter if it takes 6 seconds or 60 seconds, it's the same amount of energy.Energy is always conserved, meaning it can't created or destroyed, it can\nonly change form.\n\nPower = rate of energy\n\nPower can be measured in Watts (W) or Horsepower (HP). 1 HP is the same as 746 Watts.\n\nPower, unlike energy, is not always conserved. If we have a system where energy is flowing at a constant rate, then power is conserved, meaning the power in is equal to the power out. For standard cars, power from the engine is delivered to the wheels through a transmission. There are some losses due to the transmission, air conditioner, alternator, and other systems, but this is not considered a significant loss. If the air conditioner is turned off, your headlights are off, and you have a manual\ntransmission, the losses will be not more than a few percent. Automatic transmissions only increase losses.\n\nThe gear ratio is a transmission does not change power output. Remember,power is conserved in this case. There might be some slight change in power loss for different gear ratios, but for the most part, it's insignificant.\n\nSince we know power is the rate of energy, we can divide the energy calculated above by the time required to produce the energy. If it takes your car 6 seconds to go from 0 to 60 miles/hour, then the power is about 57000 Watts or 76.6 HP. Keep in mind, this is the average power, it doesn't\ntell us the power at any time during the acceleration. We would need detailed speed measurements from start to finish to calculate that.\n\nGiven these numbers, I would guess the engine is capable of producing 150 HP or more. How did I come up with that number? Internal combustion engines, like gasoline, Diesel, and even turbines, do not have a flat power curve. The power output is zero at zero RPM and increases more or less\nlinearly until some peak. In stock gasoline engines, the peak power is at 5000-6000 RPM or so. As a rule of thumb, the peak is generally 1000 RPM below red line. So if you could run your engine at 1000 RPM below red line,\nthen you could achieve near peak performance. If watch your tachometer, I would guess that the RPM averages much less than that, maybe even half.\nThat's why you are getting only half of the power the engine is capable of producing.\n\nRPM, power and torque are all related. Torque is simply power divided by RPM. The power out of a transmission is the same as the power in (minus small losses), but the RPM is different depending on the gear ratio. If the output shaft spins at half the speed of the input, then the output torque is double that of the input. RPM doesn't really matter in the end as far as power is concerned, remember, power is conserved. Changing gear ratios does not change the power, it only affects torque and RPM. It's easier to start with calculate power and work out RPM and torque if you need it. You can do it the other way, but it's easy to make mistakes.\n\nThe reason most cars have a transmission at all is because gasoline engines cannot produce torque over a wide range of RPM, particularly at zero RPM.Diesel electric locomotives and subways do not have transmissions with variable gear ratios because they use electric traction motors instead of\ntransmissions. Electric motors can produce torque over a wide range, even at zero RPM. This is known as the stall torque

energy is the capacity that an object has for performing work.  Work is a force times a distance.  A similar comparison might be your bank account balance and dollars.  While both are related and have the same units, your bank account is the capacity that you have to spend money.  The big difference is of course, you can never have a negative balance on the amount of energy in a system.

Look, energy is conserved, period.  It may be in the form of PE, KE, heat, etc., but it is always conserved.  My best guess is that whatever experimentalists you're thinking of probably neglected to consider heat effects of some other energy drain/source.\n\nBy the way, I think you now hold the record for the worst spelling and punctuation ever on Yahoo! Answers.

Most likely Energy in Joules. We need a context though.
