Elon Musk: We Can Power America by Covering Small Corner of Utah With Solar
During an interview Tuesday at the American Geophysical Union’s fall meeting in San Francisco, the 44-year-old CEO of Tesla Motors and SpaceX said that the U.S. could meet its electricity needs just by covering a small corner of Utah or Nevada with solar panels.
His remark was captured in this tweet from Nature News reporter Lauren Morello, who was at the event:
Musk made a similar statement during his speech at the Sorbonne University in Paris on Dec. 2.
"Let's say if the only thing we had was solar energy—if that was the only power source—if you just took a small section of Spain you could power all of Europe," he said. "It's a very small amount of area that's actually needed to generate the electricity we need to power civilization. Or in the case of the U.S., like a little corner of Nevada or Utah would power the United States."
While Musk's statement might sound a little too good to be true, as Tech Insider reporter Rebecca Harrington noted, we already have the technology to do it. More power from the sun hits the Earth in a single hour than humanity uses in an entire year, yet solar only provided 0.39 percent of the energy used in the U.S. last year.
This is why Musk thinks that solar will become the biggest energy source by 2031, as he told Tim Urban from Wait But Why. If solar is 20 percent efficient at turning solar energy into power, as it has been in lab tests, we'd only need to cover a land area about the size of Spain to power the entire Earth renewably in 2030.
Indeed, photovoltaic technology is growing in leaps and bounds. In October, renowned solar installer SolarCity (where Musk sits as chairman) unveiled a solar panel that can achieve a peak efficiency of 22.04 percent, and that's just for residential rooftops. On an industrial scale, the world’s most efficient solar cell has about double the efficiency of SolarCity's new panels at 44.7 percent.
The Land Art Generator Initiative also crunched the numbers and determined that the surface area required to power the whole world with solar would fit into 191,817 square miles of solar panels, or roughly the area of Spain.
Here's the math the project group calculated: “678 quadrillion Btu (the US Energy Information Administration's estimation of global energy consumption by 2030) = 198,721,800,000,000 kilowatt-hours (simple conversion) divided by 400 kilowatt-hours of solar energy production per square meter of land (based on 20 percent efficiency, 70 percent sunshine days per year and the fact that 1,000 watts of solar energy strikes each square meter of land on Earth) = 496,805 square kilometers of solar panels (191,817 square miles)."
Let's remember that this calculation is just for solar power alone. This doesn't even factor in all the other sources of renewable energy such as wind, geothermal, biomass or hydroelectric power.
Watch Musk's speech from Paris about clean energy future in the video below. In the clip, which starts at 29:41, Musk answers an audience member's question about the option of "sustainable" nuclear energy, but adds that he's a bigger proponent of the "big fusion power plant in the sky called the sun."
Here's the full text of his speech in Paris:
I actually think that nuclear fission, if it's in location that is not subject to natural disasters like in the case of France, there's a very high percentage of nuclear, I think that's actually a good thing. Obviously, you don't want to have nuclear fission power plants in places that are subject to natural disasters [30:00] because that obviously can go wrong. I think fission is a good approach.
Fusion is also interesting and it's exciting to see what's happening with ITER Project, which is a fusion plant that's being built in France. I do think fusion is a feasible technology. I think we can definitely make fusion work, but it is a far off technology. So to make fusion at the power plant level work is probably, I don't know, 30 years away and a lot of effort.
That's why at least for now and I think maybe even in the long-term, I'm a proponent of using the big fusion power plant in the sky called the sun. The sun is a giant fusion explosion and it shows up every day. If we have photovoltaics, solar panels, we can capture that fusion energy. It also needs to be stored in a battery so we can use it at night. Then we want to have high power lines to transfer solar energy from one place to another.
Let’s say if the only thing we had was solar energy—if that was the only power source—if you just took a small section of Spain you could power all of Europe. It’s a very small amount of area that’s actually needed to generate the electricity we need to power civilization. Or in the case of the U.S., like a little corner of Nevada or Utah would power the United States.

Cabin fever is often associated with being cooped up on a rainy weekend or stuck inside during a winter blizzard.
In reality, though, it can actually occur anytime you feel isolated or disconnected from the outside world.
What is cabin fever?<p>In popular expressions, cabin fever is used to explain feeling bored or listless because you've been stuck inside for a few hours or days. But that's not the reality of the symptoms.</p><p>Instead, cabin fever is a series of negative emotions and distressing sensations people may face if they're isolated or feeling cut off from the world.</p><p>These feelings of isolation and loneliness are more likely in times of <a href="https://www.healthline.com/health-news/yes-covid-19-cases-are-rising-why-you-still-need-to-practice-social-distancing" target="_blank">social distancing</a>, self-quarantining during a <a href="https://www.healthline.com/health/what-is-a-pandemic" target="_blank">pandemic</a>, or sheltering in place because of severe weather.</p><p>Indeed, cabin fever can lead to a series of symptoms that can be difficult to manage without proper coping techniques.</p><p>Cabin fever isn't a recognized psychological disorder, but that doesn't mean the feelings aren't real. The distress is very real. It can make fulfilling the requirements of everyday life difficult.</p>
What are the symptoms?<p>Symptoms of cabin fever go far beyond feeling bored or "stuck" at home. They're rooted in an intense feeling of isolation and may include:</p><ul><li>restlessness</li><li>decreased motivation</li><li><a href="https://www.healthline.com/health/irritability" target="_blank">irritability</a></li><li>hopelessness</li><li><a href="https://www.healthline.com/health/unable-to-concentrate" target="_blank">difficulty concentrating</a></li><li><a href="https://www.healthline.com/health/irregular-sleep-wake-syndrome" target="_blank">irregular sleep patterns</a>, including sleepiness or sleeplessness</li><li>difficulty waking up</li><li><a href="https://www.healthline.com/health/lethargy" target="_blank">lethargy</a></li><li>distrust of people around you</li><li>lack of patience</li><li>persistent <a href="https://www.healthline.com/health/depression/depression-vs-sadness" target="_blank">sadness or depression<br></a></li></ul>
What can help you cope with cabin fever?<p>Because cabin fever isn't a recognized psychological condition, there's no standard "treatment." However, mental health professionals do recognize that the symptoms are very real.</p><p>The coping mechanism that works best for you will have a lot to do with your personal situation and the reason you're secluded in the first place.</p><p>Finding meaningful ways to engage your brain and occupy your time can help alleviate the distress and irritability that cabin fever brings.</p><p>The following ideas are a good place to start.</p>
When to get help<p>Cabin fever is often a fleeting feeling. You may feel irritable or frustrated for a few hours, but having a virtual chat with a friend or finding a task to distract your mind may help erase the frustrations you felt earlier.</p><p>Sometimes, however, the feelings may grow stronger, and no coping mechanisms may be able to successfully help you eliminate your feelings of isolation, sadness, or depression.</p><p>What's more, if your time indoors is prolonged by outside forces, like weather or extended shelter-in-place orders from your local government, feelings of <a href="https://www.healthline.com/health/anxiety" target="_blank">anxiety</a> and fear are valid.</p><p>In fact, anxiety may be at the root of some cabin fever symptoms. This may make symptoms worse.</p><p>If you feel that your symptoms are getting worse, consider reaching out to a mental health professional who can help you understand what you're experiencing. Together, you can identify ways to overcome the feelings and anxiety.</p><p>Of course, if you're in isolation or practicing social distancing, you'll need to look for alternative means for seeing a mental health expert.</p><p>Telehealth options may be available to connect you with your therapist if you already have one. If you don't, reach out to your doctor for recommendations about mental health specialists who can connect with you online.</p><p>If you don't want to talk to a therapist, <a href="https://www.healthline.com/health/depression/top-iphone-android-apps" target="_blank">smartphone apps for depression</a> may provide a complementary option for addressing your cabin fever symptoms.</p>
The bottom line<p>Isolation isn't a natural state for many people. We are, for the most part, social animals. We enjoy each other's company. That's what can make staying at home for extended periods of time difficult.</p><p>However, whether you're sheltering at home to avoid dangerous weather conditions or heeding the guidelines to help minimize the spread of a disease, staying at home is often an important thing we must do for ourselves and our communities.</p><p>If and when it's necessary, finding ways to engage your brain and occupy your time may help bat back cabin fever and the feelings of isolation and restlessness that often accompany it.</p>
