Overview
Electricity, a fundamental force of nature, has been harnessed by humans for over two centuries. From the early experiments of Benjamin Franklin in 1752 to the widespread adoption of electric power in the late 19th century, electricity has revolutionized the way we live, work, and communicate. The discovery of the electron by J.J. Thomson in 1897 and the development of the first practical incandescent light bulb by Thomas Edison in 1879 were pivotal moments in the history of electricity. Today, electricity is generated from a variety of sources, including fossil fuels, nuclear power, and renewable energy sources like solar and wind power, with the global electricity market projected to reach 43,855 billion kilowatt-hours by 2025. As the world continues to urbanize and electrify, the demand for electricity is expected to increase, with the International Energy Agency predicting a 30% rise in global electricity demand by 2040. However, the production and distribution of electricity also pose significant environmental and social challenges, including greenhouse gas emissions and unequal access to electricity, with an estimated 840 million people worldwide still lacking access to electricity, according to the World Bank.
