Energy efficiency can be carried out as easily as flipping move turning off lights when you leave a room or keep the thermostat at a suitable place to establish it cold on a hot day. A typical family spends around $2,000 a year on home utility bills. Heating and cooling are on energy bills that occupy half of the energy consumption of a House, followed by large appliances and electronic devices, equipment for water heating and lighting. Below, we’ve included a few very simple steps to save energy, although often overlooked, you can apply to take advantage of their energy consumption. If you are committed to saving energy and money, consider well observe these recommendations for each category to achieve greater efficiency:-put the thermostat between 78 and 80 degrees during the warmer months. During the colder months, an adjustment of the thermostat between 68 to 70 degrees is highly recommended. -Use a programmable thermostat to manage your heating system per day and cooling needs.
Try with a peak of savings without thermostat. -Try to circulate air with portable fans through the roof to make the room feel cooler. -Turn off the TV, fan and lights or lamps when you leave a room. -Buy compact fluorescent lamps to replace incandescent bulbs which are less efficient. -Buy appliances and low consumption products.
Check Energy Guide label and look for the ENERGY STAR logo on the purchase of these items that help prevent the dreaded global warming. -Turn off or unplug electronic devices such as computers, tools, cell phones, digital cameras and MP3 Chargers, when they are not being used. -Reduce use of hot water take short showers, use cold water to wash clothes, etc – try to use natural gas instead of water heaters, dryers, stoves because they are energetically more efficient than their electrical counterparts. Consider the possibility of an economic reimbursement to use Natural Gas – perform an energy audit of origin to reduce common inefficiencies.
The history of electricity refers to the study and use of electricity, the discovery of their own laws as a physical phenomenon and the invention of devices for their use. The phenomenon, outside of his relationship with the human observer, has no history; and if it is considered as part of the natural history, it would be the same as time, space, matter and energy. As it is also called electricity to the scientific branch that studies the phenomenon and the branch of technology that is responsible for implementing it, the history of electricity is the branch of the history of science and of the history of technology which deals with its emergence, development and evolution. One of its initial milestones may be around 600 BC, when Thales noted that rubbing a rod of amber with a skin or wool, obtained small loads (triboelectric effect) which attracted to small objects, and that long time rubbing could cause the appearance of a small spark. Near the Greek city of Magnesia is they were called stones from Magnesia, which possessed magnetite. The ancient Greeks noted that the pieces of this material attracted between them, and also to small iron objects. Electricity has evolved since the perception of the phenomenon to its scientific treatment, which would not be systematic but until the 18th century. Were recorded along the ancient age and average other (rather isolated) observations as well as medical intuition (use of electric fish in diseases such as gout and headaches) referred to by authors like Plinio the elder and Scribonius long, or archaeological objects as diverse as questionable interpretation, at this point refer to the Baghdad batteryan object found in Iraq in 1938, dated in 250 BC, which resembles an electrochemical cell.
Always developed countries have used large amounts of energy to feed its technological and industrial growth, but in recent years in developing countries have become major consumers of energy for its development. Electrical power is usually generated at a power plant that converts other kinds of energy into electricity. Each system has advantages and disadvantages, but many of them are worrying environmental problems. The main feature of nuclear energy is the high quality of energy that can be produced per unit mass of material used in comparison with any other type of energy known by human beings, but surprised the poor efficiency of the process, since it wastes from an 86 to 92% of the energy that is released. Under normal operation, a nuclear power plant releases very little pollution of any kind on the environment. But it produces several types of nuclear waste. It produces a few volumes moderate low level waste; which can be removed by placing them simply somewhere that is not accessible for a few years. However, a relatively small amount, perhaps a ton is generated per year in the case of a great nuclear power, high-level waste, which poses a problem to get rid of it.
You can be expected to be dangerous for decades, centuries, even millennia, so it must be methods of disposing of it which are extremely safe. Typically, the majority of these residues are stored in media storms that require a constant and careful attention. Accidents at nuclear power plants pose a serious risk of environmental contamination. Such as the Chernobyl accident, and lately in Japanese nuclear power plants due to the earthquake and subsequent tsunami it released large amounts of radioactive contamination. Advantages nuclear energy, for example in the European union generates a third of the electrical energy that is produced in this area, thus avoiding the issuance of 700 million tons of carbon dioxide per year into the atmosphere.
