Our current power grid is basically a giant firehose of electricity going from power plants
to your house. But what if it were efficient, two-way, and let you use your neighbor's solar
panels? That's the SMART GRID!
Sup guys, Trace here. In 2003, a tree limb touched a high-voltage power line in Ohio
causing a cascading blackout that stretched across the northeast from New York to Chicago
and as far north as Ottawa, Canada. 50 million people were without power for as long as two
days. The estimated cost: six billion dollars and 11 lives. You could blame the tree branch,
the people in Ohio who should have trimmed it, or even the faulty alarm system, but really
we should blame ourselves. The North American power grid is… well it's a mess.
In 1882, Thomas Edison built the first commercial power grid in New York City, introducing the
idea of electricity distribution. Now, almost 140 years later, it's been built ad-hoc...
jury-rigged into two major grids: the Eastern and Western Interconnection, and three minor
grids: Texas, Alaska, and Quebec Interconnections. Together they comprise 1 TRILLION dollars
of hard work for public and private groups, all to provide power to the U.S. and Canada.
And it's dumb.
Right now, our power grid provides 830 gigawatts of electricity to more than 330 million people,
and yet, there's no storage system. Dumb. If you flip on your lightswitch, the local
power plant has to ramp up production, just a bit, to power that light. Also, all the
power flows one way, from generators, to stations, to your house, like an electricity firehose.
Dumb. If something breaks, they can't just run power around the problem, they have to
drive out, find it, and fix it. Things like this are immensely frustrating for utilities,
regulators, governments, and you and me. Which is why we need a smart grid. A smart grid
is to the current dumb grid as the newest smartphone is to Zach Morris' massive beige
brick-thing. Actually, no. Zack's phone was still sweet. Our grid is not.
The smart grid basically adds internet-connected computers to the mix. The utility company
sends power AND information to the houses, and then the houses send info back to tell
it how it's doing, how much it's using and also where the power is coming from. On top
of that, if you have solar power on your roof, or wind power or whatever… and the power
goes out, the grid will know you're okay, and even ask you to help power homes and facilities
nearby -- like traffic lights or emergency services! Computers at every point on the
grid would know where they are in relation to privately-owned home batteries or solar
panels, and they'd be able to communicate with them too! This internet-connected grid
could revolutionize how power is generated and distributed and make the whole trillion-dollar
mess more efficient.
Right now, 6.1 percent of all power is lost as the electricity physically runs through
the lines, heating them up and generating noise. That's about 19-and-a-half BILLION
dollars disappearing just from lines themselves. With computers talking back and forth to the
utilities everyone would know second-by-second to only route power as needed… perhaps from
local storage or solar: rather than burning coal far away because one guy is watching
TV.
It might seem obvious, but this means good things for companies, people, even the environment.
For example, if the grid knew there were batteries available, the power plants wouldn't need
to burn as much coal. Or, if the grid knew it was windy or sunny, it could pull from
the local renewable farms! You could even, as a consumer, CHOOSE to only use power from
local storage or charge your car when the cost was lower. Honestly, it sounds like a
crazy nerdy dream. Which is sort of where we are now…
Countries all over the world are trying to get their citizens excited about this new
smart infrastructure, but it's hard, and expensive. Ultimately, the smart grid will save money,
but it will also help us use distributed power generation, and help the environment by eliminating
waste and encouraging people to understand more about how they're using their own electricity.

If you're coming out of this thinking, wait, but if the grid is so crazy NOW, how does
it even work? You're in luck, my friend! Remember that blackout during the Superbowl? We looked
into how the power grid worked after that! Check it out!
Do you want to put solar panels on your roof? Get a battery for your house? Only use renewables?
Really into coal?
