Electricity is at the root of everything that we think of as modern. In a practical sense it defines modernity. All of those adjuncts to living in an advanced society that began to appear from the end of the 19th century—electric lighting then electric motors, radio, television, home appliances, and, in the last part of the 20th century, the myriad of electronic devices that have been spawned by the development of the transistor including computers and portable telephones—rely exclusively on electricity for their operation. Their widespread use would not be possible without electricity and the complex electricity supply system that has evolved to deliver it. Not only is electricity one of the foundations of a modern developed society, electricity is also capable of nourishing the advancement of a society. Something as simple as the availability of electric lighting can lead to enormous benefits in terms of levels of education and quality of life. In consequence, electricity supply is a key element of international development aid. Meanwhile the citizens of many less-developed nations yearn for an adequate electricity supply and all the benefits that it can bring. Ironically, most of the citizens of the world’s advanced societies take it for granted.
