This is a quick visual history of human-created light sources over the past ~400,000 years, from wood fires to candles to the electric light. In 3,000 BCE, the “rushlight” candle was invented in Ancient Egypt. It is made of a pithy stalk of rush soaked in animal fat. In 1500 BCE, Babylonian/Assyrian lamps were created from olive or sesame oil. They had a linen wick and were fashioned from stone, terracotta, metal or shells. In 100 CE, the Romans created the tallow candle, whi

To help electric vehicles reach ubiquity, governments and EV charging companies must ensure the availability of fast-charging infrastructure doesn’t become a bottleneck for growth. A McKinsey research In the past decade, electric vehicles (EVs) have gone from a rare sight on even the busiest roadto an increasingly common, affordable option. In 2020, EV sales set new records that surpassed expectations, particularly in countries with an eager customer base and government polic

A common complaint you hear from electric vehicle owners is about the sorry state of public EV charging: broken chargers, janky software, busted screens. But a lot of this is anecdotal, and it can be hard to find any rigorous studies that capture the current state of EV charging in the US. JD Power surveyed 11,554 electric vehicle and plug-in hybrid vehicle owners from January through June 2022 for its second annual Electric Vehicle Experience Public Charging Study. Despite b

Batteries, they do not make electricity – they store electricity produced elsewhere, primarily by coal, uranium, natural gas-powered plants, or diesel-fueled generators. So, to say an EV is a zero-emission vehicle is not at all valid. Also, since forty percent of the electricity generated in the U.S. is from coal-fired plants, it follows that forty percent of the EVs on the road are coal-powered, do you see?” But that is not half of it. For those of you excited about electric

Executive Summary: Electric car sales continue to break records, but mineral supply constraints are looming Few areas in the world of clean energy are as dynamic as the electric car market. Sales of electric vehicles (EVs) doubled in 2021 from the previous year to a new record of 6.6 million. Back in 2012, just 120 000 electric cars were sold worldwide.
