Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. In early days, electricity was considered as being unrelated to magnetism. Later on, many experimental results and the development of Maxwell’s equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.
The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field.
When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb’s law. Thus, if that charge were to move, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positive charge from an arbitrarily chosen reference point to that point without any acceleration and is typically measured in volts.
Electricity is at the heart of many modern technologies, being used for:
electric power where electric current is used to energise equipment;
electronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.
Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries. Even then, practical applications for electricity were few, and it would not be until the late nineteenth century that electrical engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution. Electricity’s extraordinary versatility means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is now the backbone of modern industrial society.
The Green Room: What happens when you put two energy experts in a room and ask them how the UK makes its renewable energy? In our latest episode we dig deep into the numbers and recent trends, and take you through all of the UK’s biggest renewable energy sources. We check out their benefits and drawbacks, and how the government plans to increase our renewable energy generation in the coming years.

Wind power is, in many ways, the bedrock of UK renewable power. On a very basic level a wind turbine comprises of rotor blades positioned at the top of very high towers. They spin as wind hits them, which produces electricity. Recent decades have seen anti-wind turbine sentiments abate significantly, and they’re currently our biggest source of renewable electricity, accounting for 18% of UK energy.
Bioenergy is a bit of a blanket term that essentially covers any gas, electricity or transport fuel generated from organic matter. That means plants, timber, agricultural & food waste, and even sewage. The really big advantage of bioenergy is that it is a lot more flexible than most renewable energies.
Solar power has long been one of the big hitters in the renewables world, at least partly because it does so well in global technology hotspots like California and China. In terms of our reliance on solar panels, it’s low compared wind and bioenergy, sitting just below 4% in 2018, but we’re certainly no slouch – we are still in the top 10 global producers of solar energy.
There are a few different types of hydroelectric power generators, but in essence, hydroelectric uses flowing water to spin a turbine, generating electricity. It’s a little difficult, because it requires specific natural features to take advantage of, but we do have several hydroelectric plants in the UK. There are more hydro projects planned for the future, but they come with a hefty price tag which may make them difficult to complete.
