Electricity is a very convenient way to transfer energy, and it has been adapted to a huge, and growing, number of uses.
The invention of a practical incandescent light bulb in the 1870s led to lighting becoming one of the first publicly available applications of electrical power.Although electrification brought with it its own dangers, replacing the naked flames of gas lighting greatly reduced fire hazards within homes and factories. Public utilities were set up in many cities targeting the burgeoning market for electrical lighting. The resistive Joule heating effect employed in filament light bulbs also sees more direct use in electric heating. While this is versatile and controllable, it can be seen as wasteful, since most electrical generation has already required the production of heat at a power station.
Electricity is however still a highly practical energy source for heating and refrigeration, with air conditioning/heat pumps representing a growing sector for electricity demand for heating and cooling, the effects of which electricity utilities are increasingly obliged to accommodate.Źródło: https://en.wikipedia.org/wiki/Electricity
This is due to the fact that the electrician with extensive experience certainly much better than the person selects the equipment which has no idea about electrical engineering.
If you then use a computer or other mobile device that can operate without being connected to the power supply, we can find help on the Internet.Many electricians announces via the Internet and we can do there a real understanding among offers electrical services. It turns out that thanks to the virtual network, you can often find cheaper electrical services in the vicinity than using, for example, with the help of neighbors in this regard.
On the other hand, cheaper does not mean better, and looking for an electrician on the Internet need to be careful..
