Most electrical accidents are due to defective equipment, unsafe installation, or misuse, and can be prevented by
following a few basic electricity safety rules:
● Make sure you use certified suppliers and electricians
● Avoid overloading power outlets with too many appliances
● Unplug appliances when not in use
● Protect electric cables
● Follow specified safety advice at all times
One lightning bolt has enough electricity to service 200,000 homes.
In one hour, the Earth receives more energy from the Sun than total world energy consumption
for a year.
Switching to the best technologies available today would save at least 40% of residential electricity consumption in most appliance categories.
Standby power accounts for 10% of residential energy use in the OECD area. 
In other words, devices doing nothing add 10% to the average electricity bill.
The Greek philosopher Thales of Miletus unknowingly experimented with static electricity in 600 BC. He rubbed
amber (elektron in Greek) with cat fur and picked up feathers. He thought the attraction was due to magnetism but in 1600, English scientist William Gilbert showed that magnetism and static electricity – that he called “electricus”, meaning amber-like – were different.
Obama’s Smart Grid Plan: On 27 October 2009, the Obama Administration announced an investment totaling $3.4 billion, for supporting Smart Grid efforts.
The terms we use to describe electricity are tributes to pioneers such as Volta who invented the electrochemical battery, Ampère and Hertz who worked on electromagnetism, Watt who developed the concept of horsepower, or Ohm whose law defines the relationship between voltage and current.
