One of the common reasons people claim to support wind and solar technologies is to reduce dependence on foreign sources of energy. For example, green energy supporter Jay Faison told the Wall Street Journal “If we expand our clean energy technologies, we’ll create more jobs, reduce our dependence on foreign sources of energy…”[i] The problem is that green energy actually increases reliance on imports instead of reducing imports.

Green energy technologies are dependent on rare earth minerals and lithium for batteries–both of which are primarily imported into the United States. Most of the world’s rare earth minerals are produced in China (85 percent); and that country supplies the United States with most of its rare earth imports (71 percent). The United States only produces 24 percent of the rare earth minerals that it needs.[ii] In 2013, the United States imported 54 percent of the lithium it used, with Chile and Argentina supplying 96 percent of those imports.[iii] Some believe that lithium may be the “new oil”, eclipsing oil as a source for geopolitical and economic power.[iv] Clearly, Tesla, who is building a gigafactory in Nevada to produce lithium-ion batteries for its cars and Powerwall storage device, needs access to low-cost lithium. In contrast to these figures, the United States now imports only 27 percent of the oil it uses domestically.[v]



Rare Earth Minerals

China began producing major amounts of rare earth minerals in the early 1980s and became the world’s leading producer in the early 1990s, with the country steadily strengthening its hold on that market. Due to China’s lack of regulatory oversight, China sold its rare earth minerals at very low prices that the Mountain Pass Mine in the United States and others in the world were unable to compete and stopped operation. As demand skyrocketed for use in green technologies and elsewhere, China capitalized on its dominant position and began restricting exports, allowing rare earth prices to rise to historic levels and at times using their dominant position as a political weapon with other countries. Several pounds of rare earth compounds are used in batteries that power electric vehicles and hybrid-electric vehicles.[vi]


This chart shows China’s dominance in the production of rare earth minerals.

China’s dominance may have peaked in 2010 when they controlled about 95 percent of the world’s rare earth production. The country began restricting their rare earth exports, which made prices rise over 500 percent for certain rare earth minerals. That made mining companies in the United States, Australia, Canada and other countries reevaluate old rare earth projects and explore for new ones. Mines in Australia began producing rare earth oxides in 2011, supplying about 2 to 3 percent of world production in 2012 and 2013. In 2012, the Mountain Pass Mine in California came back into production and the United States produced about 4 percent of the world’s rare earth elements in 2013. India has been producing about 3 percent of the world’s supply for the past decade. Indonesia, Russia, Nigeria, North Korea, Malaysia, and Vietnam are also minor producers.

With these other countries entering the market, China announced early last year that it would adhere to a World Trade Organization ruling by removing its export quotas and other restrictions on rare earth minerals.[vii] But despite this move and entry into the market of other countries, China remains the dominant producer of rare earth minerals, producing 85 percent of the world’s output and supplying 71 percent of the rare earth imports to the United States, though its share may continue to erode.


According to the US Geological Survey’s 2015 summary, the majority (over 50 percent) of lithium used in the United States is produced abroad. Furthermore, the United States only produces 28 percent of the lithium that enters the United States (the U.S. imports and exports lithium). Chile is the major source of lithium to the United States, followed by Argentina. (See table below.)

The United States currently produces lithium only at one location–the Albemarle Corporation’s Chemetall-Foote lithium brines in Silver Peak, Nevada. Albermarle is one of three companies that dominate the industry. The other companies are Sociedad Quimica y Minera de Chile SA (SQM), and FMC Corporation. Unlike OPEC, which produces 40 percent of the world’s oil supply, these three companies provide more than 90 percent of the world’s lithium.[viii] FMC is the top U.S. importer of the lithium compounds used in lithium-ion batteries, followed by (SQM). Beginning October 1, 2015, FMC increased most of its lithium product prices by 15 percent.[ix]

Tesla’s Lithium Batteries

Tesla plans to make lithium-ion batteries at its gigafactory near Reno. These batteries will be used in Tesla cars and in Tesla’s Powerwall system for storing electricity from solar energy or off-peak electricity to power homes or commercial building during peak hours of electricity demand. The $5 billion gigafactory is expected to start production this year. Tesla expects that by 2020, the gigafactory would be producing more lithium-ion batteries annually (500,000) than were produced worldwide in 2013. Thus, Tesla needs lots of lithium and relatively soon.

As a result, last year, Tesla signed a conditional lithium hydroxide supply agreement with Bacanora, which is developing a mining operation in Sonora, Mexico, and with Pure Energy Mineral, developers of a mining project in Clayton Valley, Nevada. If these two projects are able to get into production, Tesla expects to buy their lithium at a discount to the market price.[x] Both of these projects, however, are years from producing lithium. At full production, Tesla will need 17 percent of global supply. To meet the gigafactory’s near-term demand for lithium, Tesla will most likely have to import from one or more of the three major providers, particularly if it is to start producing batteries at the gigafactory this year.


The argument that switching to wind, solar, or other “green” technology will reduce energy imports is incorrect. Electric vehicles and other green technologies are dependent upon rare earth minerals and lithium—both of which are mostly imported into the United States currently, at rates of dependence far higher than our dependence on oil imports. Some even see lithium as the new oil with 90 percent of the market controlled by three companies. Tesla is trying to obtain lithium at below market prices to produce its batteries needed in its electric vehicles and for its Powerwall storage device. It will need to obtain lithium fairly soon since its gigafactory may start producing batteries this year and plans to be at full production by 2020.
