According to nutritional data, one gram of pure alcohol (ethanol) provides approximately 29 kilojoules (kJ), which is equivalent to 7 kilocalories (kcal). This makes ethanol a more energy-dense compound than both carbohydrates and protein, which each contain about 17 kJ (4 kcal) per gram.

Glycerol, a simple polyol compound, provides approximately 4.32 calories per gram, making it a distinct contender for a minor fuel source with 4 calories per gram. This sugar alcohol is a key component of triglycerides and is released into the bloodstream when the body breaks down stored fat for energy.

According to the US Department of Energy, about 45% of U.S. corn is currently used for ethanol production, highlighting corn's significant role in the biofuel industry. But while corn is a direct energy resource in this context, the answer is more complex, involving intense debates over sustainability and efficiency.

Globally, maize is the second most extensively grown crop after wheat, a testament to its widespread use not just as a food but for industrial applications. Given its versatility, many wonder: is corn a good energy source for our bodies, our vehicles, and our livestock?

According to the Food and Agriculture Organization (FAO), global biofuel production has increased significantly, highlighting the growing importance of energy yielding plants. Energy yielding plants, also known as energy crops, are specifically cultivated for their potential to be converted into fuels or directly used to produce energy.

According to a confidential World Bank report, biofuels caused a massive 75% increase in global food prices, highlighting a key disadvantage of using food as a fuel. This practice raises critical economic, social, and environmental concerns, challenging its long-term sustainability and ethics.

According to the U.S. Department of Energy, denatured ethanol (98% ethanol) contains about 30% less energy per gallon than gasoline, directly affecting fuel economy. The debate over which is better, ethanol or no ethanol, is a complex one, with the ideal choice depending on your vehicle's age, engine type, and usage patterns.

While cows and other grazing animals can survive entirely on grass, humans cannot extract any meaningful energy from it due to our unique digestive systems. This fundamental biological difference means the answer to the question, "Does grass give energy?" depends entirely on the species in question and the method of processing.

Studies show that B100 can reduce life-cycle greenhouse gas emissions by over 70% compared to conventional diesel. This makes understanding the use of B100, or 100% biodiesel, crucial for fleets and individuals seeking a cleaner fuel alternative derived from renewable resources like vegetable oil or animal fats.

Globally, sugarcane accounts for approximately 40% of the world's biofuel production. Cane energy is the bioenergy generated from both standard sugarcane and specialized energy cane varieties, offering a renewable alternative to fossil fuels.
