The 1973 oil crisis
The embargo caused an acute strain on the US economy, which had become increasingly dependent on foreign oil. The price of oil per barrel initially doubled and then quadrupled, resulting in skyrocketing costs for consumers and significant challenges for national economies. This included high inflation, stagnation in oil-importing countries, and a global recession. The embargo also contributed to a complex shift in the global financial balance of power towards oil-producing states, highlighting the vulnerability of the US to oil imports.
The Nixon administration attempted to negotiate an end to the embargo and address the resulting foreign policy challenges. These attempts included parallel negotiations with key oil producers and discussions with Egypt, Syria, and Israel to arrange an Israeli pullout from the Sinai and the Golan Heights. The embargo was eventually lifted in March 1974, after the First Egyptian-Israeli Disengagement Agreement was reached in January 1974. However, the impact of the crisis lingered throughout the 1970s, with the dollar price of energy increasing again the following year.

Electric cars
The idea of a fully electric car is not new. In fact, the first electric cars appeared before the earliest gas autos. The history of electric cars is filled with innovative attempts at four-wheeled transit.
The first practical electric cars were built in the 1830s. Scotland's Robert Anderson created a motorized carriage sometime between 1832 and 1839. However, these early attempts were more parlor tricks than practical vehicles. It wasn't until the second half of the 19th century that more practical versions were built in France and England. French physicist Gaston Planté invented the first lead-acid battery, which could store electricity onboard a vehicle. In 1881, French scientist Camille Alphonse Faure improved the design and capacity of the battery. In 1884, Thomas Parker, an English inventor, built the first production electric car in Wolverhampton. This was followed in 1888 by German engineer Andreas Flocken, who constructed the first "real" electric car.
In the late 1890s and early 1900s, the electric car manufacturing industry was relatively robust and successful. In 1897, Walter Bersey introduced a fleet of battery-powered taxis to London, and New York City had around 60 electric taxis. By 1900, electric cars accounted for a third of all vehicles on the road in the US, with 800 out of 2,370 automobiles in New York, Chicago, and Boston being fully electric. American chemist William Morrison created a six-passenger electric vehicle in 1890 with a top speed of just 14 miles per hour, but it helped spark interest in electric cars across America.
In the early 20th century, the electric car began to lose its position in the automobile market due to improved road infrastructure that required vehicles with a greater range than electric cars could offer. The rise of gasoline-powered cars, with their louder engines and greater power, also contributed to the decline of electric cars. By the 1920s, electric-car makers had either converted to internal combustion or gone out of business.
Interest in electric vehicles experienced a resurgence in the 1970s, with the passage of the Electric and Hybrid Vehicle Research, Development, and Demonstration Act in 1976, which provided government incentives for electric vehicle development in the US. NASA also helped raise the profile of electric vehicles when its electric Lunar rover became the first manned vehicle on the moon in 1971. However, electric vehicles during this time still suffered from drawbacks compared to gasoline-powered cars, with limited performance and range.
In the 1990s, newer electric vehicle prototypes began gaining popularity again. In 1996, California mandated that automakers sell a small percentage of zero-emission vehicles, leading to the development of electric models by Chrysler, Ford, GM, Honda, Nissan, and Toyota. However, interest in fuel-efficient or environmentally friendly cars declined among consumers in the US during this time due to low gas prices.
In 2006, Tesla Motors announced it would produce a luxury electric sports car with a range of over 200 miles on a single charge. Tesla's success spurred many big automakers to accelerate their work on electric vehicles. The Nissan Leaf, introduced in 2010, became the first modern pure electric, zero-tailpipe emissions family hatchback car produced for the mass market by a major manufacturer. In 2021, the UK Government announced that over 500,000 ultra-low emission electric vehicles were on the roads, and it committed to ending the sale of new petrol and diesel cars by 2030.
