Energy management" is a term that has a number of meanings, but we're mainly concerned with the one that relates to saving energy in businesses, publicsector/government organizations, and homes."
Meaning Of Energy SavingWhen it comes to energy saving, energy management is the process of monitoring, controlling, and conserving energy in a building or organization. Typically this involves the following steps: 1) Metering your energy consumption and collecting the data. 2)Finding opportunities to save energy, and estimating how much energy each opportunity could save. You would typically analyze your meter data to find and quantify routine energy waste, and you might also investigate the energy savings that you could make by replacing equipment (e.g. lighting) or by upgrading your building's insulation. 3)Taking action to target the opportunities to save energy (i.e. tackling the routine waste and replacing or upgrading the inefficient equipment). Typically you'd start with the best opportunities first. 4)Tracking your progress by analyzing your meter data to see how well your energy-saving efforts have worked.
Why is it important?Energy management is the key to saving energy in your organization. Much of the importance of energy saving stems from the global need to save energy - this global need affects energy prices, emissions targets, and legislation, all of which lead to several compelling reasons why you should save energy at your organization specifically.
Global need to save energyy Reduce the damage that we're doing to our planet,
Earth. As a human race we would probably find things rather difficult without the Earth, so it makes good sense to try to make it last. y Reduce our dependence on the fossil fuels that are becoming increasingly limited in supply.
Green Energy- Means to Conserve Energy.So what s the problem? Why aren t we using more green energy? Good question. That s what we would like to know. Especially because there are so many types of green energy.
Another problem is that some types of green energy - like wind power require that new and very large structures are built in places where there aren t too many people or houses but where there is a lot of wind and sometimes, a lot of wildlife.
y This can start to sound very complicated. But don t worry; it s not all bad. There are lots and lots of people all around the world working hard to create new technologies that are cheaper, easier to use and more attractive to energy supply companies, governments, consumers and people who have to look at the energy factories. y As well as that there are also lots of people working hard to think about how we can use less energy and therefore create fewer emissions. y But they can t do it alone and they need your help!
NEW TECHNIQUES TO DEVELOP ENERGYy y y y y y y y y y y y y y
Hydrogen from waste material. Nano tube technology transforms CO2 into fuel. Converting wastes into renewable energy resources. Waste as a renewable energy resource. Turning airborne carbon into fuel. Landfill powered garbage trucks. Water into hydrogen fuel with waste energy. Fuel from chicken feathers. Waste to energy continues to gain steam. Converting water and CO2 into fuel. Waste heat could double battery life of laptops and cell phones. Turning wastewater into ethanol. Getting bio fuel from world s garbage. Electricity and desalination from waste water.
Hydrogen From Waste Materialsy Environmentalists
are continuously searching for green and clean fuel. Until now they have been putting a lot of energy and talent into hydrogen fuels because when hydrogen is burned, the only emission it makes is water vapor. So it is a great advantage that burning of hydrogen doesn t produce carbon dioxide. Engineers at the University of Leeds are working on a project keeping hydrogen in mind. They are developing an energy efficient, environmentalfriendly hydrogen production system but with a difference. They are trying to extract hydrogen from waste materials. These materials can be vegetable oil or the glycerol by-product of bio-diesel.
Waste as renewable energy sourcesy The enormous increase in the quantum
and diversity of waste materials generated by human activity and their potentially harmful effects on the general environment and public health, have led to an increasing awareness about an urgent need to adopt scientific methods for safe disposal of wastes. While there is an obvious need to minimize the generation of wastes and to reuse and recycle them, the technologies for recovery of energy from wastes can play a vital role in mitigating the problems. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe disposal in a controlled manner while meeting the pollution control standards.
Nanotube Technology Transforms CO2 Into Fuely Presence
of surplus carbon dioxide in the atmosphere has taken center stage in the environmental science. All over the world people are worried about the excess amount of carbon dioxide in the atmosphere because it s causing undesirable changes in the surroundings such as green house effect, global warming, melting of ice caps on the glaciers etc. So most of the environmental scientists are trying to minimize the amount of atmospheric carbon dioxide.
Turning Airborne Carbon Into Fuely We are already experiencing the ill
effects of greenhouse gases in the form of global warming, glaciers and polar ice melting, rise in the sea level and sudden, unpredictable variation in weather, turning catastrophic sometimes. The eventual effect of global warming is sending a chill down the spines of environmentalists. Several teams of researchers are working overnight on carbon capture technology. It intends to remove undesirable amount of carbon dioxide, the main culprit in global warming, from the atmosphere.
Landfill Powered Garbage Trucksy The government of California is
backing an initiative between the Linde Group and Waste Management to build a liquefied natural gas facility that will produce clean liquid fuel from landfill gas using municipal waste incinerators. The facility is expected to open in 2009 and will produce up to 13,000 gallons of fuel per day. The groundbreaking project will be the largest of its kind and will enable California to tap into a valuable renewable source of clean energy while greatly reducing our dependence on fossil fuels.
Water into Hydrogen Fuel with Waste EnergyWith each passing day, scientists are coming out with unique solutions to lessen our dependence on fossil fuels. They are now thinking of turning stray forms of energy such as noise or random vibrations from the environment into useful form of energy. They want to use piezoelectric effect for such purposes. Some materials produce electricity while undergoing mechanical stress. This is known as piezoelectric effect. Small piezoelectric crystals can come up with enough voltage to create a spark which can be utilized to ignite gas.
Fuel from Chicken Feathers?y If we go by the stats, every year 11 billion
pounds of poultry industry waste accumulates annually, because we have gigantic appetite for poultry products. They can't be stuffed into pillows. Mostly they are utilized as low-grade animal feed. Scientists in Nevada have created a new and environmentally friendly process for developing biodiesel fuel from 'chicken feather meal'. Professor Manoranjan 'Mano' Misra and his team members at the University of Nevada discovered that chicken feather meal consists of processed chicken feathers, blood, and innards. Prof. Misra has been honored as the 2010 Regents' Researcher by the Nevada System of Higher Education
Converting Water and CO2 into Fuely Researchers are trying to duplicate the
natural process of photosynthesis. If successful, we can use the evil carbon dioxide emitted by power plants and industrial units to good use. This way, industrial units don t have to establish new subsidiary units for the treatment of carbon dioxide. Researchers at Sandia National Laboratories have developed a prototype machine that utilizes the sun's energy to convert water and carbon dioxide into the molecular building blocks that can be utilized as transportation fuels. If researchers can make this device produce twice the energy generated by the natural process of photosynthesis, it will do great service to environment. It will pave the way to recycle
Waste Heat Could Double Battery Life on Laptops, Cell Phonesy When we utilize any gadget or means of
comfort we know that these devices consume energy. But the energy is not utilized by devices. Some of the energy is lost in the form of friction or heat. For example when we are exploiting the power of computer processor chips, car engines or electric power plants there is a necessity of getting rid of excess heat otherwise the equipments will not perform at their optimal level. Now researchers are thinking about using this waste energy. Peter Hagelstein is the cowriter of this concept and an associate professor of electrical engineering at MIT. His paper was published in the November 2009 issue of the Journal of Applied Physics.
Turning Wastewater into Ethanoly As the world continues to search for
alternative fuels to fuel our cars and heat our homes, many different opportunities are being explored and there has finally been a significant breakthrough in turning wastewater into ethanol as an automobile fuel source. Qteros and Applied Clean Tech have teamed up to create a biofuel that will get us that much closer to having another true "green" energy source. Water treatment systems are expensive to run and have presented communities where they are located with some significant challenges. Most notably, what they can do with the sludge that is left over once the wastewater has been treated. Plant managers may no longer faced with the difficult task of figuring out this problem.
Getting Biofuel from the World s GarbageThere is plenty of garbage on this planet; in fact there is so much garbage that many developed countries are trying to dump their garbage on the lands of lesser developed countries, at a fee of course. But does dumping garbage on other places solve the problem? On the contrary it spreads pollutions and diseases. In fact it is more dangerous to dump garbage in the less developed countries (because there are neither technologies available to process it nor enough awareness). Even creating landfills wastes precious resources.
Electricity and Desalination from Wastewatery In most part of the world safe and clean
drinking water is unavailable for daily consumption and industrial use. Currently to desalinate water two kinds of technologies are being used. First is known as reverse osmosis and the second is electro-dialysis. Both of these processes need huge amount of energy. A team of scientists from China and U.S.A are working to eliminate ninety percent of the salts from seawater or brackish water. They are also trying to generate electricity from wastewater. "Water desalination can be accomplished without electrical energy input or high water pressure by using a source of organic matter as the fuel to desalinate water," reported in a recent online issue of Environmental Science and Technology.
Tips for saving energyy Dry your clothes on the line in the sun and not in the
y Have shorter showers. A lot of energy is used to make
hot water (you ll also be saving water). Likewise, wash your hands under the cold tap instead of the hot.
y Be smart with your heating and cooling.
y Open the curtains or blinds instead of turning the
y Turn off the standby that little red light on your
stereo/tv/computer uses nearly 10% of household energy.
y Turn of your lights when you don t need them.
Recycling is an excellent way of saving energy and conserving the environment. Did you know that: 1 recycled tin can would save enough energy to power a television for 3 hours. 1 recycled glass bottle would save enough energy to power a computer for 25 minutes. 1 recycled plastic bottle would save enough energy to power a 60-watt light bulb for 3 hours. 70% less energy is required to recycle paper compared with making it from raw materials.
Recycle used paper and ensure every bit is recycled. It takes 10 times LESS ENERGY to produce paper from used one.
I m a Cool Green Hero !Using the Cool Green Hero Checklist that we have provided, or using one that you have created yourself, think up at least two actions around energy that will help our environment and that you think you can achieve within the next six months.
CLEAN THE WORLDy Write down a few sentences for each cool green action that describes
what you hope to do. y If you re stuck for ideas, have a look at some of the tips that we have tried and had success with.
Turn off tap while cleaning your teeth, shaving or washing your face. You can waste can up to 9 liters a minute by just letting the water pour down the sink.
Take a short shower rather than a bath could save you up to 400 liters a week. If you do have baths, just half fill them.
Only use the washing machine and the dishwasher when you can put on a full load. It wastes both water and energy to run only a half full machine
Use a broom and bucket of water for washing down the patio rather than a steady flow of water from the hose.
Use a sponge and bucket of water to clean your car or if you use the hose, ensure you use a shut off nozzle so the water is not constantly running.
Fix any dripping tap, you can waste 90 liters a week
