Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial bio waste.
Biofuels can also mean land that could have produced food is instead being used for energy. And they can add to deforestation when land is cleared for their production.
Many countries around the world are involved in the growing use and production of biofuels, such as biodiesel, as an alternative energy source to fossil fuels and oil. To foster the biofuel industry, governments have implemented legislations and laws as incentives to reduce oil dependency and to increase the use of renewable energies. [117]
Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2]
Biofuels Digest recently published its "30 Hottest Companies in Renewable Chemicals and Materials" list, giving a glimpse into the wonderful world of clean tech. I didn't know much about biofuel ...
Biofuel development and use is a complex issue because there are many biofuel options which are available. Biofuels, such as ethanol and biodiesel , are currently produced from the products of conventional food crops such as the starch, sugar and oil feedstocks from crops that include wheat , maize , sugar cane , palm oil and oilseed rape .
Biofuel can be produced from any carbon source that can be replenished rapidly e.g. plants. Many different plants and plant-derived materials are used for biofuel manufacture. Perhaps the earliest fuel employed by humans is wood. Evidence shows controlled fire was used up to 1.5 million years ago at Swartkrans, South Africa.
Biofuels are also considered a renewable source. Although renewable energy is used mostly to generate electricity, it is often assumed that some form of renewable energy or a percentage is used to create alternative fuels. Research is ongoing into finding more suitable biofuel crops and improving the oil yields of these crops.
