Fast facts

Biodiesel can reduce greenhouse gas emissions by up to 86%

The U.S. produces well over a billion gallons of biodiesel each year

The story

Biodiesel is a renewable energy source derived from vegetable oils, animal fats, and recycled cooking oil. It can be used in diesel engines without modifications, making it an accessible alternative for many drivers. National Biodiesel Day, observed on March 18, honors the legacy of Rudolf Diesel, who believed that his engine would run on vegetable oil, a vision that aligns with modern efforts to create sustainable energy solutions.

Read the full story

Launched in 1999, National Biodiesel Day serves as a reminder of the importance of renewable energy in combating climate change. As global temperatures rise and fossil fuel reserves dwindle, biodiesel presents an opportunity to reduce our carbon footprint. Awareness initiatives on this day encourage individuals, communities, and businesses to consider biodiesel in their energy choices.

The benefits of biodiesel extend beyond emissions reductions, it also supports local economies by creating jobs in the agricultural and energy sectors. This renewable fuel can be produced from a variety of resources, making it adaptable to different regions. In the U.S., biodiesel is primarily made from soybeans, but other feedstocks like algae and used cooking oil are gaining traction.

As we celebrate National Biodiesel Day, it's crucial to acknowledge the global context of this movement. Countries around the world are investing in biodiesel technology, aiming to create a more sustainable future. From Europe to Asia, various governments are implementing policies to promote biodiesel use, highlighting its potential as a key player in the transition to cleaner energy sources.

Did you know?

Rudolf Diesel's Vision

Rudolf Diesel originally designed the diesel engine to run on peanut oil, showcasing his commitment to sustainable energy.

First Commercial Production

Commercial biodiesel production in the U.S. began in the early 1990s.

Biodiesel Blends

Biodiesel can be blended with petroleum diesel in various ratios, with B20 (20% biodiesel, 80% diesel) being a common blend.

Environmental Benefits

Using biodiesel can significantly reduce particulate matter and carbon monoxide emissions compared to traditional diesel.

Biodiesel Standards

In the U.S., biodiesel must meet the ASTM D6751 standard to ensure quality and performance.

Global Production

Worldwide biodiesel production has grown substantially in recent years.

Biodiesel and Waste Cooking Oil

Recycling used cooking oil into biodiesel helps reduce waste while providing a renewable energy source.
