Who started biofuels and when?

The concept of biofuels dates back to the early 19th century, but significant development began in the 1900s. In 1893, Rudolf Diesel demonstrated an engine that could run on peanut oil, highlighting the potential of vegetable oils as fuel. The modern biofuels industry gained momentum in the 1970s in response to the oil crisis, leading to increased interest and investment in renewable energy sources.
