Household Energy Optimization With resent load shadings and unplanned power outages in the country it becomes clear that the energy crisis have not been resolved to its full. As domestic houses still uses electricity without caution, high energy consumption remains a bigger issue. An investigation will be conducted to determine one household service that uses large amount of electricity and find alternative ways to reduce energy consumption 1 Introduction South Africa is one of the country that is facing a crises in the energy sector, with resent problems such as load shadings and unplanned power outages in the country, It’s is clear that South Africa‘s energy usage is at its most high levels. In South Africa energy have been taken for granted, which have lead to higher consumption in energy than normal, in return Eskom have been struggling to provide continues energy for the country due to shortage of electricity to supply. The problem of high energy consumption, have not been resolved with a high number of residences still using electricity carelessly and carefree, a lot can be done to improve the usage of electricity and reduce energy consumption. So it becomes much more clear that one can start taking precautions about they are own energy consumption and start making changes about the way they use electricity in their own homes in order to assist with lowering the energy consumption of the country. The objective of this paper is to investigate about the household appliance that uses a great amount of electricity and find alternative ways to reduce consumption of electricity by that particular service. The rest of the paper is organised as follows. In the next section, a background to the problem is provided... ... middle of paper ... ...t Eskom during peak time, was to implement usage of renewable technology in our household as they reduce high electricity consumption. It is our best interest to reduce energy consumption and to save electricity to assist in reduce the peak time and to insure future availability of electricity in our country. 4 Reference [1] Albe B, Ernst U, Les B, Standby power consumption of domestic appliances in South Africa.

According to the National Bureau of Economic Research, DST increases overall energy consumption by “approximately 1 percent” (Kotchen) and rises to 2-4 percent in the fall. The use of air conditioning, television, lighting, and other appliances causes the residential energy demand to

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,
Last but not least, people favors the use of renewable energy instead of nuclear power in the last few decades, such as wind power, solar power, geothermal energy and biofuel. They are now more willing to adopt energy conservation and energy efficiency measures. Carrying out energy efficiency measures is the cheapest and fastest way to reduce the use of any forms of energy sources and in term reduce carbon emissions.
...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.
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
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.
South Africa wastes lots of money on non renewable energy sources in order to create electricity for example coal. The building of Wind Turbines, Hydroelectric power plants etc. Are costly, but once built are free as they use renewable energy sources. They do not contribute to global warming unlike nuclear power plant which is extremely bad for the air. There is also a risk of an accident such as the Chernobyl accident.
Per year South Africa uses 1.3 % of the world’s total energy. South Africa’s main energy comes from coal, but one quarter of the coal we mine is exported to other countries. In 2009 71.1% of the total energy sources in South Africa were coal and hydroelectric energy had 0,1%. The one major reason hydroelectric energy in South Africa is so low is because this country is a water scarce one, which means that the hydroelectric power stations don’t have enough water to produce electricity efficiently. Eskom produces 95% of the electricity in South Africa and about half the electricity in Africa. Most of the electricity that is produced is from coal, but not all of it, other sources include gas, wind, hydroelectric and nuclear energy.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
In fact, environment crisis could solve by considering two important aspects, environment crisis occurred due to emissions of carbon dioxide, which caused by processes of generate electricity in order to meet the increase of demand for it. So the two important aspects are: to avoid abuse of energy consumption and to obtain environmentally friend electricity generation. This essay concentrates on the second aspect in order to offer some solutions of this problem.
