Here’s a question for you how many people does it take to turn on a light bulb the answer seems simple, just walk into a dark room flip a switch and instantly

you can see right well the truth is there’s a lot more to generating and delivering electrical power then you’ve probably imagined hi Emily Patrick Sullivan

with energy now and this energy 1 0 1 video explains

the system used to generate electricity, and it also explains what it takes to turn on a light bulb to understand energy we first need to start at the source mother nature provides a natural resource we used to generate power from natural gas to coal ocean tides to mountain wins

the energy we need to create electricity must first be mined harnessed or collected from the earth some of these resources are finite including fossil fuels like cold oil, but others are unlimited like solar or wind-powered but a lump of coal or a strong

breeze alone won’t create the power that turns on your light for every energy source a chemical or mechanical process is required to turn it into usable

electricity everyday researchers work to find innovative ways to use our limited resources process raw materials harness renewables more efficiently and discover entirely new energy sources today the majority of America ‘s electricity comes from thermal power plants fuels like coal natural gas biomass in uranium are used to heat water until it produces steam which powers a turbine and generates electricity that the steam turns propeller-like blades Round the rotor inside the turbine, this turning rotor connects to the main shaft which spins magnets with a coil inside a generator’s the generator inside a turbine that converts mechanical energy into electrical energy and creates electricity steam is an inefficient method of producing electricity because the water

can be recycled and reused as it changes back-and-forth between liquid and gaseous states transporting the heat from the power plant to your home is an entirely different process current technology cannot cost-effectively store large amounts of electricity so significant challenges exist when it comes to transferring that electricity across

long distances just enough heat has to

be generated to meet demand at all times and be transmitted through powerlines to reach your light switch too much or too little power can crash the transmission

system And cause a blackout that’s why a complex a mix of logistics management and infrastructure is needed to transmit electricity from power generators

to consumers enter the electricity grid Also known as merely the grid the North American electricity the grade is made of for large grid systems the western grid the Eastern grid the Texas grid and a grid covering the Canadian province of Quebec these independent regional networks of power plants

and transmission lines carry electric energy at a high voltage within the area to local utilities there are minimal links between the four which means electricity generated from a winter vine in West Texas cannot reach an apartment building

in New York City for heat to move through

one of the four grids a device must first increase its voltage called a transformer then the electricity.

can travel long distances across high-voltage transmission lines these high-voltage lines are generally stable between giant metal towers they stretch for miles from power plants to local substations

in each Neighborhood, you probably saw substations along the side of the road and wonder what they do well their job is stepping down electric voltages from levels as high as 7 6 5, 000 V closer to the 1 10 V you use in your home the electricity from the powerline on your street passes through another a transformer which steps down the voltage once more

and then it travels along the line into your house from there if the electricity enters your breaker box and it is then distributed to light sockets, and outlets all you have to do is flip a switch so as you can see from the raw materials to the powerlines on your street; there’s so much more to electricity ecosystem than meets the eye
