There\u2019s no doubt that we have experienced terrible suffering and economic hardship over the last several months. But as hard as it is to imagine right now when we\u2019re still in the middle of the pandemic, climate change has the potential to be even more devastating.<\/h1>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p><strong>The pandemic<\/strong> has also reminded us<strong> how much innovation<\/strong> is needed to<strong> prevent<\/strong> a <strong>climate disaster<\/strong>. The best numbers I have seen estimate that <strong>the economic slowdown due<\/strong> to <strong>COVID-19<\/strong> reduced global emissions by around\u00a0<strong>8 percent<\/strong>. That\u2019s not nothing, but the austerity that got us there obviously isn\u2019t sustainable. If we\u2019re going to <strong>address climate change<\/strong>, we need to find new ways to do things that don\u2019t release <strong>greenhouse gases<\/strong>, including <strong>how we move around<\/strong>.<\/p>\n<div class=\"st__content-block st__content-block--text\">\n<p>When most people picture what contributes to climate change, vehicles are one of the first things that <img loading=\"lazy\" class=\"alignright wp-image-121282\" src=\"https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2020\/10\/bill-gates-temiz-ve-yesil-bir-gelecekte-nasil-hareket-edecegiz.jpg\" alt=\"\" width=\"320\" height=\"196\" srcset=\"https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2020\/10\/bill-gates-temiz-ve-yesil-bir-gelecekte-nasil-hareket-edecegiz.jpg 798w, https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2020\/10\/bill-gates-temiz-ve-yesil-bir-gelecekte-nasil-hareket-edecegiz-300x183.jpg 300w, https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2020\/10\/bill-gates-temiz-ve-yesil-bir-gelecekte-nasil-hareket-edecegiz-768x470.jpg 768w, https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2020\/10\/bill-gates-temiz-ve-yesil-bir-gelecekte-nasil-hareket-edecegiz-500x306.jpg 500w, https:\/\/www.enerjigazetesi.ist\/wp-content\/uploads\/2020\/10\/bill-gates-temiz-ve-yesil-bir-gelecekte-nasil-hareket-edecegiz-80x50.jpg 80w\" sizes=\"(max-width: 320px) 100vw, 320px\" \/>come to mind. Here in the <strong>United States<\/strong>, transportation is the number one contributor to emissions. But you might be surprised to learn that it only contributes <strong>16 percent<\/strong> of global emissions. That\u2019s a smaller percentage than\u00a0<em>how we plug in,\u00a0grow things<\/em>, and\u00a0<em>make things<\/em>. Still, <strong>decarbonizing<\/strong> how we move around is essential if we\u2019re going to get to zero net emissions.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>Our goal here isn\u2019t necessarily to make people move around less (although we should look for ways to cut back on <strong>driving, flying, and shipping<\/strong> where possible). As we\u2019ve seen over the <strong>last several months<\/strong>, <strong>economies suffer<\/strong> when people are forced to stay close to home.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>We want more people and goods to be <strong>able to travel<\/strong>. For some of the world\u2019s poorest people\u2014like smallholder farmers in sub-Saharan Africa\u2014the ability to move goods from rural areas to city markets can make the difference between life and death. To do that, we need to make sure transportation remains affordable to everyone. Products like <strong>gasoline, diesel<\/strong>, and even <strong>jet fuel<\/strong> are the standard for a reason: they can send you a <strong>long way for a low cost<\/strong> per gallon.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>So, how exactly do we <strong>fuel<\/strong> our need to move around without <strong>emitting greenhouse gases?<\/strong> The answer is simple, even if making it happen won\u2019t be: use <strong>clean electricity<\/strong> to run all the vehicles we can, and <strong>get cheap alternative fuels<\/strong> for everything else.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>Let\u2019s start with the former. The good news is that we\u2019ve made lots of progress on <strong>electric vehicles<\/strong>, or <strong>EVs<\/strong>. Unlike many of the green alternatives I\u2019ve written about before on this blog, you can go out and buy one right now if you want. <strong>The batteries<\/strong> that power them have seen an<strong> 85 percent<\/strong> price drop <strong>since 2010,<\/strong> so they\u2019re getting more affordable to purchase (although they\u2019re still more expensive than gas-based options). Plus, increased competition<strong> in the market means<\/strong> there are more choices available to customers than ever before, from<strong> compact sedans to sleek sports cars<\/strong>. You\u2019ll even be able to <strong>buy an all-electric pick-up truck soon<\/strong> thanks to legacy companies like<strong> GM<\/strong> and <strong>Ford<\/strong> and <strong>new carmakers<\/strong> like Rivian and Bollinger.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>Several companies are developing better and cheaper batteries that will hopefully make EVs a realistic option for every car owner. This video features QuantumScape, a manufacturer working to commercialize the next generation of battery technology. (I\u2019m invested in their work both on my own and through\u00a0<em>Breakthrough Energy Ventures.<\/em>)<\/p>\n<div class=\"st__content-block st__content-block--text\">\n<p>EVs excel at short-haul travel. That means they\u2019re great options for personal cars and even medium-duty vehicles, like city buses and garbage trucks. But even if we develop cheap, long-range EVs that are powered by zero-carbon sources, electrification isn\u2019t an option for many types of transportation.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>The problem is that batteries are big and heavy. The more weight you\u2019re trying to move, the more batteries you need to power the vehicle. But the more batteries you use, the more weight you add\u2014and the more power you need. Even with big breakthroughs in battery technology, electric vehicles will probably never be a practical solution for things like 18-wheelers, cargo ships, and passenger jets. Electricity works when you need to cover short distances, but we need a different solution for heavy, long-haul vehicles.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>This is where cheap alternative fuels come in. There are several different kinds of these fuels, but the one you\u2019re probably most familiar with is biofuels.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>Today\u2019s advanced biofuels are a lot different from the first-gen ones you\u2019ve heard about, such as ethanol. Some are made from plants that aren\u2019t grown for food, so they need little to no fertilizer (which you might remember is\u00a0a big emitter of greenhouse gases). Others are made from agricultural byproducts, like corn stalks and the pulp that\u2019s left over from making paper. Some of these fuels can even be dropped into existing engines without any modifications needed.<\/p>\n<div class=\"st__content-block st__content-block--text\">\n<p>I\u2019m optimistic about these biofuels, but it\u2019s too soon to think about replacing gasoline and other fossil fuels with them. Research on advanced biofuels is still underfunded, and they aren\u2019t ready to be deployed at the scale we need. We need a lot more innovation before they become a realistic, cost-effective option for long-haul transportation.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>Another type of alternative fuel is electrofuels. By using electricity to combine the hydrogen molecules in water with the carbon in carbon dioxide, we can create a liquid fuel that works in existing engines. The carbon dioxide this process uses is captured directly from the atmosphere, so burning electrofuels doesn\u2019t add to overall emissions. They\u2019re very expensive, though. Depending on what fuel you&#8217;re replacing, electrofuels can cost anywhere from 3 times to 7 times as much as fossil fuels. And like with EVs, the electricity used to create them needs to be from zero-carbon sources to be a real solution.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>Switching to electric vehicles and alternative fuels is the most effective way we can move toward zero emissions from the transportation sector. Although there are some other measures we can take to reduce emissions\u2014like using less carbon-intensive materials to make cars, using fuels more efficiently, and moving around less\u2014zeroing out all transportation emissions is going to require massive breakthroughs in these two areas.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>These technologies need to get much cheaper than they are today. That means finding ways to manufacture them at scale and to make sure they perform comparably to their fossil fuel counterparts.<\/p>\n<\/div>\n<div class=\"st__content-block st__content-block--text\">\n<p>I\u2019m inspired by the progress we\u2019ve made so far, but we have a long road ahead of us (no pun intended). To prevent the worst effects of climate change, we need to get to zero net greenhouse gas emissions in every sector of the economy within 50 years. Decarbonizing how we move around is going to require lots and lots of innovation, just as in the other areas I\u2019ve written about. I\u2019m eager to see what role today\u2019s technologies will play in a zero-carbon future and to discover what new breakthroughs will emerge in the years to come.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Earlier this month, I wrote about how\u00a0COVID-19 is a cautionary tale for climate change.
