Electricity is delivered to millions of homes for heat, communication, entertainment and other needs.
Electricity was once little more than a novelty, used to massage feet and for wild experiments. Since then, electronics have infiltrated virtually every part of our society and industry from how we manufacture goods to how we bank money and even how we store food. Additionally, electricity and electronics have made it possible for light to perform functions never conceived of in earlier ages.
To Communicate
Electricity has given people of many nations and cultures a chance to communicate ideas, transmit news and to provide educational information for people of other cultures to benefit from. Because of electricity, learn-at-home language courses can help millions of people around the world to speak French, English, Spanish and more, and because of electrical systems such as cell phones, calls can be placed from busy city centers to the most remote parts of the globe. The Internet is another innovation of electronics. This allows millions to communicate with friends, families and colleagues, to broadcast their interests to the general public, and to entertain and educate themselves with videos and text available in a virtual world maintained entirely by electronic servers and computer systems.
To Heal
Electronics and light, especially in the form of laser light, have been integral in many treatments of illnesses from the mundane to the deadly. Laser eye surgery can improve the vision, while electronic incubators keep premature babies healthy and happy in a disease-free and temperature-controlled environment. Emergency workers rely on both light and electricity when driving to the scene of a crash or to a heart attack victim's home, and electric shocks can be used to start a person's heart after it stops. Perhaps most importantly, electronics and parts of the light spectrum are used in medical research to find cures and treatments for diseases, viruses and conditions such as influenza, cancer and AIDS.
To Sell
Perhaps the greatest benefactor of electricity and light is the marketplace. Lights are used not only to illuminate homes at night, but in devices such as cell phones, computer displays, cars, televisions and even advanced computer processors. Electronics and laser lighting have led to greater precision and efficiency in mass production, the ability to buy and sell goods anywhere in the world and the ability to carry your entire fortune and credit rating on a small plastic card with an electro-magnetic strip.
