Many developed nations are undergoing massive efforts towards lowering the consumption of electricity, an effort that would not be sufficient unless people and industries will continue to use and develop more energy efficient technologies to offset the increased demand for energy due to a growing population.
In recent decades our societies became conscious about the need to preserve natural resources and to reduce energy consumption. Shifting from the conventional way of producing electricity to the renewable and sustainable energy generated from wind, solar, geothermal or nuclear, helps to drastically reduce the carbon emissions in the world.
A major area of developing new strategies in regards to reducing electrical energy consumption is targeted at the residential “lighting and appliances”. For example, our South Florida homes are mostly “all-electrical”, and multiple studies show that “lighting and appliances” usually account for over one quarter of the electrical energy consumption for an entire household. Only by switching from incandescent lighting bulbs to compact florescent ones, the electricity savings are in the range of more than half. Besides the immediate energy savings, it was demonstrated that even if “a compact florescent light bulbs may cost twice as much as an incandescent, it lasts ten times as long” (Lester, 81). Since the prices for the compact florescent lamps recently dropped due to technological advancements, it makes it easier for all of us to participate in conserving electricity use.
In regards to “appliances”, studies suggest that the use of television sets, video or audio systems, computers, refrigerator, cooking ranges, microwaves, washer and dryers account for more than half of the total household “lighting and appliances” energy consumption. In our country, regulatory agencies are getting involved in raising the standard for the new appliances, allowing only the production of appliances that meet new efficiency requirements. These agencies are also looking into regulating the small amount of current that is consumed by appliances when these are turned off. These are called “phantom loads” and appear in all appliances that are plugged in, even if the appliances are completely turned off. One can easily avoid this wasted electricity by unplugging the appliance when not in use. Studies estimate that “roughly five percent of US residential electricity use is from appliances in standby mode” (Lester, 86).
It is important to acknowledge that our school building and infrastructure were built to latest standards. As a student at FGCU, I observed that the building itself, parking lots, the dorms, sidewalks and roads infrastructure were developed in a very conscious and efficient way.
For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.
Not only is nuclear power friendly to the environment, but it is almost always available, and many countries are starting to use it more. Renewable energy sources like solar and wind en...
Reducing and altering one’s energy consumption, and more broadly, saving resources of energy, is a key factor in ensuring that this world is kept and maintained liveable for future generations. By incorporating energy consumption methods in our daily lives, sustainable urbanisation will be achieved and our community will be ever more environmentally friendly. The practical methods and first step measures households should take in reducing their energy consumption, is by utilising energy smart principles and renewable energy resources. These have become easily accessible and affordable for many as the government continues to emphasise the importance of sustaining our environment and the importance of people being conscious of energy expenditure from
So you turn off lights when you leave a room, use CFL light bulbs throughout the house instead of incandescent, and keep the temperature indoors a little cooler in winter and higher in summer. Wondering why your energy bills remain so high? The answer might be flying out your windows and walls without you realizing it. According to the Department of Energy, a professional energy audit can identify exactly where your energy dollars are used -- and easily help the average homeowner save anywhere from 5 to 30 percent on utility bills. Even a preliminary DIY energy audit, focusing on two key areas, will assist you in significantly cutting back on your normal energy usage.
While incandescent light bulbs are not as energy efficient when compared to newer alternative halogen light bulbs, compact florescent lamps (CFL), and light emitting diodes (LED), incandescent light bulbs should not be phased out due solely to their inefficiency. Phasing out incandescent light bulbs will not greatly reduce the level of mercury in the environment; additionally incandescent factories are now closed in the United States due to the phase out, many people in the lighting manufacturing industry have lost their jobs. An examination of the CFL, one of the more predominant alternatives to the incandescent, may reveal shortcomings in the CFLs projected life expectancy, overall quality, and potential health hazards. Instead of incandescent light bulbs being phased out for their inefficiency, compact florescent lamps should be banned for their dangerous qualities.
...also save energy by using motion censoring for doors and sinks. The dining rooms and foyers should have dim-able light switches. Another way to save a lot of energy is to make a master switch at the front door that turns off all lights. That way you never leave a light on when you aren't at home. You should use natural gas cook tops and ovens to cut down on electricity.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Based on Laurel Nesbit, a program assistant in the Office of Sustainability here at UF, our campus manages to utilize 470,000 Megawatts of energy annually. This figure is generated from all the energy-consuming gadgets that operate on our campus on a daily bases. These gadgets include computers that are left turned on over the night even they are not in use, copiers, and the fume hoods in our laboratories. Admittedly, the success and the health of wellbeing of the students is contingent upon some of these equipment. For instance, the laboratories need the fume hoods in order to keep the experimenters safe. Instead of casting these necessities away, we can develop alternatives which will be capable of generating energy in order to compensate for the electricity that we endlessly
In addition to the fact that solar, wind, and hydro power are local resources, they are also emission free resources. Emissions and pollution are a key concern with traditional power sources. The coal-fired plants that dominate U.S. energy production also produce more emissions than any other energy source. “Em...
ways. The use of electricity will reduces the usage of the earth’s resources such as gas and oil.
Household energy conservation is a very practical and realistic approach to conserving energy within our society. US households consume a tremendous amount of natural gas as well as electric energy. It has been calculated that the amount of energy consumed within the US increased exponentially from about 1850 to 1975. If energy continued to increase at this rate, we would be experiencing severe energy shortages in our current society. Luckily, steps towards conservation, including various energy regulations, have curbed that growth somewhat, brining the predicted 160 Qbtu/yr for the year 2000 down to around 93.8 Qbtu/yr by the year 1996. However, household energy usage is still a major issue as households consume about 38% of the total consumed energy and contribute greatly to natural gas consumption and issues such as global warming. Therefore, it is important that people understand how we use energy in the household and what steps can be taken to conserve that energy.
In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely effective when providing energy for small establishments such as a house or small store, but hydrothermal power would be a more plausible solution for factories or large establishments....
One distinctive element in world stories is that economics was developed within the context of an engineering technology, therefore industrial world require better economic technique and innovation for getting proper benefit from their goods. For this purpose the equipments by which the goods are manufacture are likely to be cent percent efficient or approaches to it. regardless of their nature and purpose.Moreover the globe facing the energy decline and energy along with their resourses is becoming rare and rare in every tick of the clock. Today!.. the burning question is that how the man can save the natural resourses whether it is power,water or even gas. The report deals with the technology by which industrial sector can reduce their energy consumption also their supplier reduce the distribution cost.
