How Much Land is Needed to Power the U.S. with Solar?

The Biden administration has set a goal of reaching 100% clean electricity throughout the U.S. by 2035, and solar power is a key for this American energy transition.

In the last decade alone, solar has experienced an average annual growth rate of 42% in the U.S. thanks to federal tax credits, declining costs, and increasing demand. It is projected that more than one in seven American homes will have a solar power system by 2030.

To put this trend into perspective, this graphic uses data from the United States Department of Energy to see how much land would be needed to power the entire country with solar panels.

Solar Panels Across the Ocean State

The U.S. has 102.9 gigawatts of total solar installed capacity which is equivalent to 965 square miles, roughly the size of the country’s smallest state, Rhode Island. This current solar capacity generates enough electricity to power 18.6 million American homes, which is nearly 13% of the nation’s households.

According to a report from the National Renewable Energy Laboratory, roughly 22,000 square miles of solar panel-filled land (about the size of Lake Michigan) would be required to power the entire country, including all 141 million households and businesses, based on 13-14% efficiency for solar modules.

Many solar panels, however, reach 20% efficiency, which could reduce the necessary area to just about 10,000 square miles, equivalent to the size of Lake Erie.

Solar Installations Spreading Across the States

Today, solar represents only 3% of the total U.S. electrical generation.

While California has traditionally dominated the market, other states like Florida and Texas are expanding rapidly, boosted by the residential market.

Large companies with clean energy goals such as Walmart, Apple, Target and Amazon have also helped push solar adoption to near-record levels in 2021.

How much land is needed to power the U.S. with solar?

Despite having a high installation cost, the technology tends to bring savings in the long term. An average-sized residential system has dropped from a price of $40,000 in 2010 to roughly $20,000 in 2020. Along with this, solar panels can save between $10,000-$30,000 over a 30-year lifetime.

Between land and rooftops, the United States has more than enough space to build all the solar panels necessary to power the country. Until then, the future of clean electricity will also depend on hydro, nuclear, geothermal, and wind energy.

Charted: 4 Reasons Why Lithium Could Be the Next Gold Rush

Visual Capitalist has partnered with EnergyX to show why drops in prices and growing demand may make now the right time to invest in lithium.

4 Reasons Why You Should Invest in Lithium

Lithium’s importance in powering EVs makes it a linchpin of the clean energy transition and one of the world’s most precious minerals.

In this graphic, Visual Capitalist partnered with EnergyX to explore why now may be the time to invest in lithium.

1. Lithium Prices Have Dropped

One of the most critical aspects of evaluating an investment is ensuring that the asset’s value is higher than its price would indicate. Lithium is integral to powering EVs, and, prices have fallen fast over the last year:

DateLiOH·H₂O*Li₂CO₃**
Feb 2023$76$71
March 2023$71$61
Apr 2023$43$33
May 2023$43$33
June 2023$47$45
July 2023$44$40
Aug 2023$35$35
Sept 2023$28$27
Oct 2023$24$23
Nov 2023$21$21
Dec 2023$17$16
Jan 2024$14$15
Feb 2024$13$14

Note: Monthly spot prices were taken as close to the 14th of each month as possible.

**Lithium carbonate (MB-LI-0029)

2. Lithium-Ion Battery Prices Are Also Falling

The drop in lithium prices is just one reason to invest in the metal. Increasing economies of scale, coupled with low commodity prices, have caused the cost of lithium-ion batteries to drop significantly as well.

In fact, BNEF reports that between 2013 and 2023, the price of a Li-ion battery dropped by 82%.

YearPrice per KWh
2023$139
2022$161
2021$150
2020$160
2019$183
2018$211
2017$258
2016$345
2015$448
2014$692
2013$780

3. EV Adoption is Sustainable

One of the best reasons to invest in lithium is that EVs, one of the main drivers behind the demand for lithium, have reached a price point similar to that of traditional vehicle.

According to the Kelly Blue Book, Tesla’s average transaction price dropped by 25% between 2022 and 2023, bringing it in line with many other major manufacturers and showing that EVs are a realistic transport option from a consumer price perspective.

ManufacturerSeptember 2022September 2023
BMW$69,000$72,000
Ford$54,000$56,000
Volkswagon$54,000$56,000
General Motors$52,000$53,000
Tesla$68,000$51,000

4. Electricity Demand in Transport is Growing

As EVs become an accessible transport option, there’s an investment opportunity in lithium. But possibly the best reason to invest in lithium is that the IEA reports global demand for the electricity in transport could grow dramatically by 2030:

Transport Type202220252030
Buses 🚌23,000 GWh50,000 GWh130,000 GWh
Cars 🚙65,000 GWh200,000 GWh570,000 GWh
Trucks 🛻4,000 GWh15,000 GWh94,000 GWh
Vans 🚐6,000 GWh16,000 GWh72,000 GWh

The Lithium Investment Opportunity

Lithium presents a potentially classic investment opportunity. Lithium and battery prices have dropped significantly, and recently, EVs have reached a price point similar to other vehicles. By 2030, the demand for clean energy, especially in transport, will grow dramatically.

With prices dropping and demand skyrocketing, now is the time to invest in lithium.

EnergyX is poised to exploit lithium demand with cutting-edge lithium extraction technology capable of extracting 300% more lithium than current processes.

Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.

In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.

Chinese Dominance

Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.

The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and Li Auto models.

CompanyCountry2023 Production
(megawatt-hour)

CATL🇨🇳China242,70034%
BYD🇨🇳China115,91716%
LG Energy Solution🇰🇷Korea108,48715%
Panasonic🇯🇵Japan56,5608%
SK On🇰🇷Korea40,7116%
Samsung SDI🇰🇷Korea35,7035%
CALB🇨🇳China23,4933%
Farasis Energy🇨🇳China16,5272%
Envision AESC🇨🇳China8,3421%
Sunwoda🇨🇳China6,9791%
Other-56,0408%

In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.

The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.

Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now effectively sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.

Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.
