  • 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 iswell 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 whateverand 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 neededperhaps 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.

  • Go Planet! Sponsor?

  • 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?
