Transcript of electricity

A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. This may mean that we need to reduce the amount of energy we use or simply build more energy facilities.
Electricity is a secondary energy source, meaning that it is obtained from the conversion of a primary energy source. Energy conversion efficiency of electricity is superior to that of other types of secondary energy, such as gasoline or fuel gas, and its conversion involves lower emissions of carbon dioxide
Electricity for powering our homes is made in power stations.

A power station contains large machines called turbines, which are turned very quickly.

Power stations need large amounts of energy to turn the turbines. Most use heat energy produced from burning coal. Others use wind energy or moving water. The spinning turbine causes large magnets to turn within wire coils - these are the generators. The moving magnets within the coil of wire causes the electrons (charged particles) to move within the coil of wire.
things you didn't know about electricity
Electricity travels at the speed of light - more than 186,000 miles per second!

A spark of static electricity can measure up to three thousand (3,000) volts.

A bolt of lightning can measure up to three million (3,000,000) volts, and it lasts less than one second!

how electricity is used
Household electricity use generally makes up about a third of total electricity consumption in most developed nations.
Using data from the European Union we can give an example of
how electricity demand is split among different sectors.
