Electricity Today

Today humans are totally dependent on electricity to live. This is because electricity makes our lives easier. We use it for powering mostly everything. Thing such as computers, the television, lights. The computer is a big one people use them every day for just about everything. We use them for papers and projects for school or developing new technologies to improve civilization. About how many times do you use electricity in just one day? Just think about it when we have a temporary black out people don’t know what to do with themselves. Some people even flip the light switch even though there is no power they are just so use to it. Electricity has not really changed since it was discovered; the only thing that has really changed with electricity is how it is acquired. We are using wind to create power water (such as the Hoover dam) to generate electricity. Scientists still study and experiment to learn more about electricity. Right now, most of our electricity comes from burning fossil fuels (oil, natural gas, and coal). The combustion of the fuel generates the flow of current electricity. The problem is that fossil fuels are nonrenewable resources and will eventually run out. If we want to keep using our televisions, air conditioners, microwave ovens, and computers, we need to find another way to make electricity. Scientists today are experimenting with alternate fuel sources like the sun, wind, water, and radioactive elements.

The picture shows human dependence on electricity, particularly the developed countries. The electric power grid id the most complex man- made networks in the world (far more complex than the internet).

The pictures are of the United States and another of the world at night. They show just how much we depend on electricity to live (this is most true for developed countries). There are so many lights on all over the Earth that when you see this picture you are amazed at how much electricity we actually use even at night. I know that I did not, I had no clue that there were so many people using electricity all over the world that’s just something that you don’t think about.
