Electricity is a common term encompassing several of phenomena affecting from the presence and flow of electric charge. These involve many recognizable phenomena, such as static and lightning electricity, but in addition, less common concepts, such as the electromagnetic induction and electromagnetic field.

Power Usage .

In general form, the word "electricity" refers to a number of physical results. In scientific usage, nevertheless, the term is unclear and these related, but different, concepts are improved identified by more accurate terms:

• Electric charge: a property of subatomic particles, which regulate their electromagnetic interactions. Electrically charged matter is leverage by, and produces, electromagnetic fields.

• Electric current: a flow or movement of electrically charged particles normally measured in amperes.

• Electric field: an influence created by an electric charge on other charges in its vicinity.

• Electric potential: the capability of an electric field to do work on an electric charge, normally measured in volts.

• Electromagnetism: a fundamental interaction among the magnetic field and the existence and motion of an electric charge.

Electrical events have been studied since antiquity, though science advances were not made until the seventeenth and eighteenth centuries. Useful applications for electricity however stayed few, and it would not be in the late nineteenth century that engineers were capable to put it to industrial and residential use. The quick expansion in electrical technology at this time converts to industry and society. Electricity's exceptional versatility as a source of energy signifies it can be put to an almost limitless set of programs which include heating, lighting, communications, transport and computation. Electrical power is the backbone of industrial society, and it is anticipated to remain so for the foreseeable future.

Electricity behind its Usefulness

Global climate change is one of the most difficult to understand in the environment, political and economic issues confronting society now. Greenhouse gas emissions are the effects of almost every activity associated with the latest life. The huge portion of the greenhouse gas effect is due to carbon dioxide which is emitted mainly by the combustion of fossil fuels.

Carbon Dioxide is an essential gasses found in the atmosphere. Carbon Dioxide normally appears to our atmosphere. This is the normal atmospheric cycle to our planet. Our electricity then increases this because electricity source comes mainly in Coal burning. Coal burning generally is a pure carbon but if mix with oxygen this becomes carbon dioxide. If carbon dioxide increased our surface temperature will also increase.

Supposed you’re inside a bus and the window is tightly closed but heat of the sun can enter inside the window. What happens then the heat of sun trapped in the bus and no way to escape. This eventually turns into a hotter bus. That’s what happens to our earth when carbon dioxide increases. If our temperature increases, unpredictable weather condition follows. Seems a little bit scary but it is true. Notice that what happens now, floods are almost scary this is because our atmosphere is too hot that the ice in the North Pole and South Pole has melted.

Let’s try our self to save electricity as Global warming is rapidly increasing. In a century we increase 1 degrees Fahrenheit and it will double in the next century. What will happen to our future? Visit our website http://currentcost.net/ to know more about proper power usage
