So I'm going to talk about two stories today. One is how we need to use market-based pricing to affect demand and use wireless technologies to dramatically reduce our emissions in the transportation sector. And the other is that there is an incredible opportunity, if we choose the right wireless technologies, how we can generate a new engine for economic growth and dramatically reduce C02 in the other sectors.
I'm really scared. We need to reduce C02 emissions in ten to fifteen years by 80 percent in order to avert catastrophic effects. And I'm astounded that I'm standing here to tell you that. What are catastrophic effects? A three-degree centigrade climate change rise that will result in 50 percent species extinction. It's not a movie. This is real life. And I'm really worried, because when people talk about cars -- which I know something about -- the press, and politicians, and people in this room are all thinking, "Let's use fuel-efficient cars." If we started today, 10 years from now, at the end of this window of opportunity, those fuel-efficient cars will reduce our fossil fuel needs by four percent. That is not enough.
But now I'll talk about some more pleasant things. Here are some ways that we can make some dramatic changes. So ZipCar is a company that I founded seven years ago, but it's an example of something called carsharing. What ZipCar does is we park cars throughout dense urban areas for members to reserve by the hour and by the day, instead of using their own car. How does it feel to be a person using a ZipCar? It means that I pay only for what I need. All these hours for a car sitting idle, I'm not paying for it. It means that I can choose a car exactly for that particular trip. So here's a woman that reserved MiniMia, and she had her day. I can take a BMW when I'm seeing clients. I can drive my Toyota Element when I'm going to go on that surfing trip.
And the other remarkable thing is that I think it's the highest status of car ownership. Not only do I have a fleet of cars available to me in seven cities around the world that I can have at my beck and call, but heaven forbid that I would ever maintain or deal with the repair or have anything to do with it. It's like the car that you always wanted, that your mom said that you couldn't have. I get all the good stuff and none of the bad.
So what is the social result of this? The social result is that today's ZipCar has 100,000 members driving 3,000 cars parked in 3,000 parking spaces. Instead of driving 12,000 miles a year, which is what the average city dweller does, they drive 500 miles a year. Are they happy? The company has been doubling in size every since I founded it, or greater. People adore the company and it's better, you know? They like it. So how is it that people went from the 12,000 miles a year to 500 miles? It's because they said, it's 8 to 10 dollars an hour and 65 dollars a day. If I'm going to go buy some ice cream, do I really want to spend 8 dollars to go buy the ice cream? Or maybe I'll do without? Maybe I would have bought the ice cream when I did some other errand. So people really respond very quickly to it, to prices.
And the last point I want to make is, ZipCar would never be possible without technology. It required that it was completely trivial, that it takes 30 seconds to rent -- to reserve a car, go get it, drive it. And for me, as a service provider, I would never be able to provide you a car for an hour if the transaction cost was anything. So without these wireless technologies, this as a concept could never happen.
So here's another example. This company is GoLoco. I'm launching it in three weeks. And I hope to do for ridesharing what I did for carsharing. This will apply for people across all of America. Today 75 percent of the trips are single-occupancy vehicles. Yet 12 percent of trips to work are currently carpool. And I think that we can apply social networks and online-payment systems to completely change how people feel about ridesharing and make that trip much more efficient.
And so when I think about the future, people will be thinking that sharing the ride with someone is this incredibly great social event out of their day. You know, how did you get to TED? You went with other TEDsters. How fabulous. Why would you ever want to go by yourself in your own car? How did you go food shopping? You went with your neighbor, what a great social time. You know it's going to really transform how we feel about travel. And it will also, I think, enhance our freedom of mobility. Where can I go today and who can I do it with? Those are the types of things that you will look at and feel.
And the social benefits. The rate of single-occupancy vehicles is, I told you, 75 percent; I think we can get that down to 50 percent. The demand for parking, of course, is down, congestion, and the CO2 emissions. One last piece about this, of course, is that it is enabled by wireless technologies. And it's the cost of driving that's making people want to be able to do this. The average American spends 19 percent of their income on their car. And there's a pressure for them to reduce that cost, yet they have no outlet today.
So the last example of this is congestion pricing, very famously done in London, when you charge a premium for people to drive on congested roads. In London, the day they turned the congestion pricing on, there was a 25 percent decrease in congestion overnight. And that's persisted for the four years in which they've been doing congestion pricing. And again, do people like the outcome? Ken Livingston was reelected. So again, we can see that price plays an enormous role in peoples' willingness to reduce their driving behavior. We've tripled the miles we drive since 1970 and doubled them since 1982. There's a huge slack in that system. With the right pricing we can undo that.
Congestion pricing is being discussed in every major city around the world and is -- again -- wirelessly enabled. You weren't going to put tollbooths around the city of London and open and shut those gates. And what congestion pricing is, is that it's a technology trial and a psychological trial for something called road pricing. And road pricing is where we're all going to have to go. Because today we pay for our maintenance and wear and tear on our roads with gas taxes. And as we get our cars more fuel-efficient, that's going to be reducing the amount of revenue you get off of those gas taxes, so we need to charge people by the mile that they drive. Whatever happens with congestion pricing is that those technologies will be happening with road pricing.
Why do we travel too much? Car traveling is underpriced and therefore over-consumed. We need to put this better market feedback. And if we have it, you'll decide how many miles to drive, what mode of travel, where to live and work. And wireless technologies make this real-time loop possible.
這些又稱之為網狀網路，因其為網狀系統，每台裝置都能延展該網路，你們可能之前都曾聽聞過，以下我舉幾個例子說明，你接下來也會聽到Alan Kay 談到這些，筆電在孩子開機後，就會開始和教室裡的每個孩子進行通訊，甚至是整個學校及村落，而通訊系統的成本多少？每個月，零元！
So I want to move now to the second part of my story, which is, when are we going to start doing this congestion pricing? Road pricing is coming. When are we going to do it? Are we going to wait ten to 15 years for this to happen? Or are we going to finally have this political will to make it happen in the next two years? Because I'm going to say, that's going to be the tool to turn our usage overnight.
And what kind of wireless technology are we going to use? This is my big vision. There is a tool that can help us bridge the digital divide, respond to emergencies, get traffic moving, provide a new engine for economic growth and dramatically reduce CO2 emissions in every sector. And this is a moment from "The Graduate." Do you remember this moment? You guys are going to be the handsome young guy, and I'm going to be the wise businessman. "I want to say one word to you, just one word." "Yes, sir?" "Are you listening?" "Yes I am." "Ad-hoc peer-to-peer self-configuring wireless networks." (Laughter) These are also called mesh networks. And in a mesh, every device contributes to, and expands, the network, and I think you might have heard a little bit about it before.
I'm going to give you some examples. You'll be hearing later today from Alan Kay. These laptops, when a child opens them up, they communicate with every single child in the classroom, within that school, within that village. And what is the cost of that communication system? Zero dollars a month. Here's another example. In New Orleans, video cameras were mesh-enabled so they could monitor crime in the downtown French Quarter. When the hurricane happened, the only communication system standing was the mesh network. Volunteers flew in and added a whole bunch of devices. And for the next 12 months, mesh networks were the only wireless that was happening in New Orleans.
Another example is in Portsmouth, UK. They mesh-enabled 300 buses. And they can speak to these smart terminals you can look at the terminal and be able to see precisely where your bus is on the street, and when it's coming, and you can buy your tickets in real time. Again, all mesh-enabled. Monthly communication cost: zero. So the beauty of mesh networks: You can have these very low-cost devices. Zero ongoing communication costs. Highly scalable. You can just keep adding them, and as in Katrina, you can keep subtracting them; as long as there's some, we can still communicate. They're resilient. Their redundancy is built into this fabulous decentralized design.
What are the incredible weaknesses? There isn't anybody in Washington lobbying to make it happen, or in those municipalities, to build out their cities with these wireless networks, because there's zero ongoing communications cost. So the examples that I gave you are these islands of mesh networks, and networks are interesting only as they are big.
How do we create a big network? Are you guys ready again -- "The Graduate"? This time you will still play the handsome young thing, but I'll be the sexy woman. These are the next two lines in the movie. "Where did you do it?" "In his car." So you know, when you stick this idea -- (Laughter) -- where would we expect me, Robin Chase, to be thinking is, imagine if we were to put a mesh-network device in every single car acrosss America. We could have a coast-to-coast free wireless communication system. I guess I just want you to think about that.
And why's this going to happen? Because we're going to do congestion pricing; we are going to do road tolls; gas taxes are going to become road pricing. These things are going to happen. What is the wireless technology we're going to use? Maybe we should use a good one. When are we going to do it? Maybe we shouldn't wait for the ten to 15 years for this to happen. We should pull it forward.
So I'd like us to launch the wireless Internet interstate wireless mesh system. And require that this network be accessible to everyone, with open standards. Right now in the transportation sector, we're creating these wireless devices. I guess you guys might have FastPass here, or EasyLane, that are single-purpose devices in these closed networks. What is the point? We're transferring just, like, a few little data bits when we're doing road controlling, road pricing. We have this incredible excess capacity. So we can provide the lowest-cost means of going wireless coast-to-coast. We can have resilient nationwide communication systems. We have a new tool for creating efficiencies in all sectors. Imagine what happens when the cost of getting information from anywhere to anywhere is close to zero. What you can do with that tool. We can create an economic engine. Information should be free, and access to information should be free, and we should be charging people for carbon.
I think this is a more powerful tool than the Interstate Highway Act, and I think this is as important and world-changing to our economy as electrification. And if I had my druthers, we would have an open-source version in addition to open standards. And this open-source version means that it could be -- if we did a brilliant job of it -- it could be used around the world very quickly. So going back to one of my earlier thoughts. Imagine if every one of these buses in Lagos were part of the mesh network. When I went this morning to Larry Brilliant's TEDTalk prize -- his fabulous networks -- imagine if there was an open-source mesh communications device that can be put into these networks, to make all that happen. And we can be doing it, if we could get over the fact that someone is -- with this little slice of things is going to be for free, and we could make billions of dollars on top of it. But this one particular slice of communications needs to be open source.
So let's take control of this nightmare. Implement a gas tax immediately. Transition across the nation to road-tolling with this wireless mesh. Require that the mesh be open to all, with open standards. And of course use mesh networks. Thank you.
