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.
Awesome talk on the future of solar power by @elonmusk #AGU15 #gpsSTEM https://t.co/obX8f6RVJg— GPS UC San Diego (@GPS UC San Diego)1450208560.0
His remark was captured in this tweet from Nature News reporter Lauren Morello, who was at the event:
Musk: "You could take a corner of Utah and Nevada and power the entire United States with solar power." #AGU15— Lauren Morello (@Lauren Morello)1450206272.0
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.

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>
