# Electricity and power generation

❶People are trying to make more of our electricity in ways that are good for the environment , like using wind power or solar power.

In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.

We use them every day, but no one really gives them much thought. What are we talking about? Why, voltage sources, of course! Batteries and generators are two of the most common sources of voltage that power our daily lives. Like a river current is the flow of water molecules, electrical current is the flow of charged particles.

Did you know that electrical current is affected by the voltage and resistance in a circuit? Electric circuits can be configured to power several loads, such as light bulbs, in series or in parallel.

Power is a word we use all the time, but do you really know what it means?

Because Britain is north of the equator, the sun is always to the south of us in the sky. This means that in Britain it is best to put solar panels facing south, so that the sun shines on them for as much of the day as possible.

Electricity can also be a lot cleaner and nicer than the alternative. In , the London Underground started to use electric trains because it meant there was no dirty, smelly smoke from steam engines in the tunnels and stations.

All underground railways around the world soon did the same thing. Lots of electricity is generated by burning fuels that create greenhouse gases and contribute to global climate change. People are trying to reduce this by generating more energy by environmentally-friendly methods like wind or solar power.

Nuclear power stations often look similar to coal or gas power stations with lots of big cooling towers. Electricity can be very dangerous when it travels through you. It can seriously hurt or even kill people.

Not all items that use electricity have to be plugged into mains sockets. Batteries can be used to store small amounts of electricity so that it can be used in small things that you can carry around like iPods and video game players. Coal — coal is turned into electricity by burning it to make steam to turn a turbine; unfortunately, this makes carbon dioxide that causes global warming Cooling towers — these are used at power stations to get as much heat as possible out of steam that has been used to make electricity; this makes the power stations more efficient.

They are normally very wide towers, and sometimes look as though they have clouds coming out of them! It saves money, and helps the environment.

Electricity is a type of energy that we use to power lots of things around our homes. It is used to power lights, mobile phones, TVs, radios, and even the computer that you are reading this on. To use all this electricity, we have to make it – this is called generation.
