All of humanity just won a really important victory in our battle to lower the CO2 emissions that are causing climate change. Tesla CEO Elon Musk introduced the world to the Powerwall, a wallmounted battery for your house which aims to accelerate our transition to clean solar and windpower. Before the powerwall, there was no way to store the energy generated from the panels that capture sunlight on our roofs. So during the day they could give you the power you needed, but at night, you had to rely on the grid, which gets most of its.
Electricity from coal, natural gas, and nuclear reactors. There had been some early home batteries out there, but nothing that was nearly this affordable. But Tesla, which has built thousands of large, lithiumion battery packs for its growing electric car business, was able to produce a similar battery for buildings at a scale that dropped the production costs dramatically. The lowest capacity model will cost just $3,000. And this is the first generation of the productbefore Tesla's even completed building its massive new Gigafactory, or any real competitors have entered the market, events that will surely push the price down.
Even further, while increasing the energy storage capacity of the Powerwall. Here's how it works. When the sun is out, solar panels will power your house and charge the Powerwall at the same time. And when the sun goes down, this charged battery will kick in to meet most or all of your electricity needs until the sun comes back up again the next morning. This is gamechanging. More and more people will go completely offgrid. Every building whether it's a home, office, business, warehouse, factory they can all.
Install solar panels and some Powerwalls and instantly see their fossil fuelgenerated electricity needs drop significantly. Not every building will be able to go completely solarpowered, but most will get pretty close, especially as our appliances become more and more energy efficient. And it gets even better. The powerwall will be connected to the Internet and the rest of the energy grid. Here in Southern California, and most other heavily populated places, the electricity company charges us a lot more when we use electricity during peak timethat's in the afternoon and early evening when the temperatures are warmest and most of us are.
Home and still awake. The Tesla battery is smart, and knows when electricity is cheapest, so that's when it will draw from the grid to charge itself. And then, during peak time when you need electricity, the battery will power the house. Sometimes, you'll be able to sell back unused power to the utility company during peak time to even make a profit. It's basically going to make each individual building its own power station. Overnight, Tesla seems less a futuristic car company, and more like the man who inspired the company's name, a revolutionary electricity engineer named Nikola.

Retrofitting Net Zero Turning Existing Homes into Net Zero Homes
Here at Halco we do what's called Retrofit NetZero and what we mean by that is we're taking existing old homes, sometimes homes from the 1800s and, what we're able to do is, we're able to first of all, come in a do a home energy evaluation and we're able to tighten up that home through all of our different methods of insulation and air sealing and all the different products and services we offer. We're able to tighten that home right down just like it was a new home. And then from there we introduce renewable.
Energy. And so we will come in and very typically use geothermal taking the energy from the earth, and we''ll make all the heating, the air conditioning, and how water with geothermal, then will pair the geothermal up with either solar or wind to make the electricity. Either the solar or the wind will make all of the power for the geothermal plus the baseload electricity to run the lights and such, and at the end of the day the people have no energy bill ever again. And what we call that is retrofit net zero.
Solar Powered Classroom
We live in the fossil fuel age right now but eventually we will need a new way to make electricity. There is some magic to solar power. My name's Aaron. I'm a fourth grade teacher at Central Park School for Children in Durham, NC. My whole goal as a teacher is to develop problem solvers. It doesn't work without the wires connected. Cause that makes an open circuit, right We studied the different ways of making electricity like wind power, hydro, nuclear. It all lead up to solar power because that is the cleanest way to make electricity.
And I was just playing around with it in my head and asked them do you want to make our class room solar powered and of course there was a loud, yes! Solar system tour guide and then I drew a sun and a solar panel. It's not really like the real ones that we did, it's just, I put it on that. Kickstarter gave us an opportunity to reach a really large audience of people all around the world who were really excited about this idea. Our class has been studying energy and we love solar energy. We would love to have a.
Solar energy classroom so our class could be off the grid. It was amazing to see how far this idea spread. We're hoping to raise eight hundred dollars but we raised $5,000 dollars from backers all over the world. First we had to get all the pieces for our system. And the kids and the parents came together on two Saturdays and we had work days. They helped get the panels, and get all the bolts and nuts and put them onto the racks and move those racks of the solar panel.
Up onto the roof. So as they saw the pieces come together they had kind of control and understanding over what we were doing. Those are the wires that take the electrons all the way to our classroom and there are a hundred feet. Also, the charger controller, if you look right here, it shows how much electricity is coming in and going to the batteries. They've learned about electricity on a lot of different levels and if you have a big idea, how to make it happen. We've been without electricity since yesterday. We're going to turn the electricity back on.
This afternoon. We are going to flip the switch and be completely off the grid. We're just going to be running on solar energy. Our project shows fourth graders can understand how solar power works and that it can work for everyone. Wake up in the morning at 7 o clock. The sun is coming up, can you go for a walk I think it's something everybody has access to and can do with little problem. The kids are learning that we don't have to use all of that energy. How we can make our.
House more energy efficient and how we can possibly get solar panels at home. There's this understanding for them that they see themselves in an active role making a difference When they become professionals and engineers and idea makers, then they're going to be solving those problems of how we can make clean electricity that doesn't make our earth warmer, that doesn't pollute areas where people live. We got solar panels we don't need power lines. Instead of just studying electricity and what electricity is, the students have made electricity. We made our classroom solar powered.

Spain Privatizes the Sun Solar Power Collection Tax
Solar power in Spain a lot of people are angry that spain has essentially privatize the sunday put together a consumption tax on solar power via a Royal Decree it taxes people who are gathering sunlight on the wrong in other words you can pay to have a professional installation done um up solar panels and a and a large installation with an official utility company if you choose to have the install done privately so to speak you can have to pay you can be forced to pay a fine.
Up to 30 million euros for illegally gathering sunlight without paying attacks the tax happens to be just enough to make sure that homeowners who are gathering and storing solar energy cheaper then the statesponsored providers have to pay a tax that makes it slightly more expensive completely disincentive Ising the advancement in creativity of ways to harness solar power I think this is a real problem I i understand why the government is doing it on the Secretary of State for Energy is being labeled a backup toll and it's high enough to make sure that it will be slightly cheaper to keep.
Buying energy from the current official providers I think this is a real problem I'm the equipment has decreased about eighty percent in Spain in prison terms of price to to harness solar power on your own if you were thinking this is really cheap I'm going to take advantage of this this tax essentially makes it an I know when Louis yeah I I can't believe I'm hearing this I I don't know what types have a taxes like this are at the poorest citizens a spanner are hit with but this one.
Is despicable I I can't believe this is happening I mean Europe is supposed to be the place where are the place where people are pioneering in areas like this well I understand that the economic situation in Spain is problematic right now I was just in Spain last week and talking to a lot of different people about the job situation about the economic situation I understand that but there's another subway to view this which is OK the government can can recoup or get additional tax revenues by doing this.
But the other side if it would be what about a complete energy revolution in Spain by allowing people to save the money by by doing the installations wouldn't without the statesponsored providers and turn Spain into a bastion of alternative energy over the longer term and maybe Spain maybe the economic situation is so bad that Spain can't whether the temporary loss of revenue that's going to be good for Spain in the same way that well I don't wanna make a direct comparison but that sugar cane and ethanol in Brazil has been very good for Brazil.
And I know that there's still tons of problems but so so it may not be a the best analogy but I just completely disagree that this is the best way to go about you completely disincentive Ising people from continuing to develop ways to to harness solar power more cheaply by just saying hey if you do that you can end up paying the same amount or more than if you just did the kind of tired all things going with the state providers I completely disagree with that its yeah it's a lack of foresight and let's keep in mind.
Now with solar power you it can actually pump energy that you collect from a sign back into the grid I but that doesn't really help the government the individual gets money for that well I hadn't been in the long term it it really can't in the long term a cat alright so we're gonna keep following the story there send me your thoughts there was actually a diesel tax in Finland at one point with the same idea a because diesel was providing much better gas mileage etc an additional tax that kind of took away the benefit and it just didn't make any.
The Most Astounding Fact Neil deGrasse Tyson
What is the most astounding fact you can share with us about the Universe The most astounding fact is the knowledge that the atoms that comprise life on Earth the atoms that make up the human body are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures These stars, the high mass ones among them went unstable in their later years they collapsed and then exploded scattering their enriched guts across the galaxy guts made of carbon, nitrogen, oxygen and all the fundamental ingredients of life itself.
These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems stars with orbiting planets, and those planets now have the ingredients for life itself So that when I look up at the night sky and I know that yes, we are part of this universe we are in this universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up many people feel small because they're small and the Universe is big.
