 So when Yosef first asked me to speak here, he asked me to speak about new energy systems like the ones that my company is developing. But then I got here, and I met Charles Eisenstein, and I decided that I needed to speak about new and old energy systems. You see, for most of life on earth, energy has looked like this. For millions of plants in every nook and cranny of the earth have directly harnessed sunlight and stored it in organic molecules. And those energy and those molecules has been distributed throughout the food web by us eating each other. Now, human, now when humans discovered fire, that changed profoundly. All of a sudden, energy was decentralized in fires inside our homes. We use stolen sunlight, energy that was embedded in trees that we cut down for firewood. We stored that energy in our hearth stones and we transmitted it from village to village via the torches that we carried. Now, for the past three generations, we've lived in the fossil electricity paradigm. In this paradigm, energy is centralized. We produce it in mega power plants owned by corporations and governments. We use dead sunlight to power our energy. This is fossils from trees and plants that have been compressed under the earth for millions and millions of years until they become these little dense energy packets that we extract at 300,000 times the replenishment rate. We store that energy in toxic batteries that we also withdraw from underground and we distribute it via electricity to our homes and factories where we then proceed to turn it back into heat and mechanical energy at huge efficiency losses. In fact, efficiency is the reason that we need to use fossil fuels in the first place. When you have energy technologies that are so inefficient, you need fuels that are very energy dense. We can change that system, but I want to give you some examples of what I mean first. The engine in your car only turns 20% of the energy in the fuel into movement. The other 80% is wasted as heat and air pollution. The traditional coal-fired power plants that many of our nations depend on are only 35% energy efficient. And by the time that energy gets to our home, only 11 to 27% of the energy in those original fuels is actually usable. This reminds me a bit of the kid trying to eat spaghetti. Only 20% makes it into his mouth, the other 80% ends up on the floor. It's a lot of fun. Until we have to clean it up. So I'm a scientist and because of that, I couldn't help myself but put in a graph. The vertical axis here is power in terawatts. That's a measure of the energy consumed per second. The horizontal axis is yours. Now you see two lines on this graph. One is green and one is red. The green line represents the energy used by all other 8 million species on our earth collectively. The red line represents human energy consumption. Before we discovered fire, our energy consumption was like every other species on our planet. Then we discovered fire and then we discovered electricity. This is the change in energy consumption over just three generations. Now if we continue our energy status quo, this is where we'll be mid-century. Now there are two problems with that. The first is that one single species, humankind, will use more energy than all of the other species on our planet combined. The other problem is that fossil fuels can't sustain this level of consumption. In fact, there's only one energy source that will. And that's the sun, providing us with 89,000 terawatts of energy. Now it's worth stopping and noting here that sunlight is all the energy that we have here on earth. Sunlight is our direct sunlight. It's our wind, it's our hydropower, it's our wave energy, it's even the fossil fuels that we pull up from underground. We need to know how to use all those sources of energy, especially the ones that we have in the world immediately around us. But most importantly, we need to know how to directly harness sunlight and store it over long periods for the survival and the thriving of our species. Now thankfully, nature has developed this wonderful system called photosynthesis, whereby plants directly harness sunlight and store it in sugars. My company, at One Earth Designs, isn't nearly as smart as nature, but we're working hard to follow her lead, and this is where we've gotten so far. We've developed a solar concentrator that directly harnesses 92% of the sun's energy, and that's on the market today. You can see it even just down the street here. We've also been developing a set of rechargeable organic batteries, solar thermal batteries. These are synthesized from plant oils. They store energy in sugars just like plants do. They're non-toxic, and they have a long lifetime, because it's a regenerative organic system. It's also optimized for your main energy needs. Many of you might not realize, but only 20% of the energy you use inside your home is electricity. The other 80% is for cooking, heating, cooling, and refrigeration, thermal energy. If you take a solar photovoltaic panel on your rooftop and you try to drive that thermal energy, you'll only get 1 to 5% of the sun's energy as thermal output. With our systems, you'll get 87%. So this system is rolling out this year in India, alongside our partners at Tata Trust. We're very excited about it. It's the first of its kind, and we're now moving on to our next frontier. Starting to learn not just from plants, but also from animals. Our next step is to develop a range of thermal batteries that's designed a lot more like proteins. There are two conformational states, an on-state and an off-state. And it's triggered by a small light impulse. So what this allows us to do is two things that have never been done before. The first is to store solar thermal energy, not for hours, but for days and weeks, so that we can go through monsoon seasons and winter times and crazy summers in New Zealand and still power with solar energy. The second thing is to store much more energy than we've been able to store before with the sun and release it on demand to the household. Just like your body is able to control when it releases fat and sugar and protein molecules, your home in the future can control when it releases the energy storage from its solar thermal systems. This is very exciting. These technologies are opening up a whole new paradigm of energy, the age of sunlight. In this paradigm, energy can be distributed. You generate it inside your home and you share home to home. It's living sunlight that you directly harness from the sun, and it's stored in organic batteries instead of toxic batteries mined from under-earth. A lot of people have been very excited about this technology, and in fact we've got two very generous purchase offers at the moment for our business, but we haven't sold, and the reason is that we didn't start here. We started here in a humble home in the Himalayas when this family invited me into their tent. Their traditional fuel systems were disappearing, and the cooking fire was creating so much smoke that the air inside their home was 10 times more polluted than the air in Beijing. I stayed with this family and helped them develop a solar-powered stove, and they helped me survive in a place where I would never have been able to survive on my own. They taught me the love and friendship and trust that can come from depending on each other for day-to-day survival. That's something I never feel I can pay back, so I wake up every morning thinking about how I can pay it forward. For example, when our customers can't pay in cash, we barter with them for local agricultural goods. When the roads are completely impassable for cars, we go out by horse and yak and motorcycle to still deliver to our customers. When local charcoal sellers threaten our customers because they're using solar energy, we're there to support them and protect them, and we think of ourselves as being an integral member of the community beyond business, collaborating on community projects that make a difference in people's lives beyond solar, like helping to finance people getting to the hospital, environmental cleanup projects when minds come in and threaten our communities, taking a stand. Even projects like helping our women get access to much-needed sanitary pads. Over the past four years that we've had our products on the market, we've saved 500,000 working days for women, and thank you, and about $1 million in fuel costs for our families. We've also abated more than 60,000 trees worth of carbon dioxide, and we've brought down the air pollution levels in our family's homes by a factor of five. We've won about 23 different international awards for this work, and had the honor of working alongside people like Archbishop Desmond Tutu and Prince Friso of the Netherlands. What started as a hyper-local project to solve a particular problem for a family of 100 nomadic herders in the Himalayas has now become a global business that's still community-focused, and the reason is that 2.8 billion other people around the world face the exact same challenges as our families in the Himalayas. So we work so hard every day to try to change that situation. Our new technologies, our new emerging technologies, are opening up new paradigms and energy. Families in the emerging markets are already leapfrogging over dirty fossil fuel technologies in order to arrive in the age of solar. This technology is for everyone. We don't want to leave anybody behind. We live at this very interesting time in history. In fact, it's a fascinating time in our evolution. When the decisions we make could end up being life or death decisions, not only for us, but for countless other species on our earth. We have a choice. We can stay in the age of fossil electricity and bear the consequences that come along with it, or we can step forward into the age of sunlight. So I hope you'll all join me in stepping into the light. Thank you.
