![]() Rudolph Diesel, for example, test-fired his first engine using peanut oil after pulverized coal was found inappropriate. ![]() It has been decades since the automotive industry began using biofuels. We must find alternative energy sources to sustain the pace of living, and urgently explore environmentally friendly, renewable, and sustainable energy resources. The discovery of new reserves is possible during this period, extending the deadline. According to projections, if these reserves continue to deplete at the current rate, they will all run out by 2060. Apparently, the world’s recoverable oil reserves are decreasing by four billion tonnes per year. They contribute significantly to climate and environmental imbalances due to their high carbon emanation. For centuries, mankind has used fossil fuels derived from carbon sources. As an umbrella term, it covers all forms of energy, including renewable (biomass, hydro, solar, geothermal, wind, and tidal) and non-renewable (nuclear, coal, and petroleum). Notwithstanding the awareness and need for energy, mankind has devised several technologies to amplify energy. Humans have developed a multitude of approaches to produce energy because they assess its utility, starting with the exploitation of timber and progressing to current synthetic fuels. This review also discusses the various generations of biofuels in attaining carbon neutrality, biofuel’s impact on the environment, applications in agriculture, and limitations.Įvery country’s socio-economic growth is correlated with its energy expenditure. The present review aims to provide a comprehensive outlook of the role of alternative or biofuels in the agriculture sector, in terms of economic feasibility and carbon footprint, for sustainable development. The revenues from bioenergy projects can provide food and a better diet for small farming communities, thereby improving their quality of life. ![]() The aim to end malnutrition and hunger (SDG 2) requires a sustainable system for food production as well as resilient agriculture practices to improve agricultural productivity. Bioenergy includes a number of socio- economic, technical as well as environmental benefits that helps in achieving the UN sustainable development goals (SDG). Several studies have compared alternative fuels with conventional fuels, and it has been proven that using alternative fuels can significantly reduce traditional fuel consumption. The carbon footprint measurement has the potential to assess and compare carbon emissions generated by agricultural products and to identify points for improving environmental performance. Agriculture significantly benefits from the use of renewable resources. ![]() Nowadays, CF is considered as the prime indicator of environmental impact, and its calculation is in utmost demand. However, if low carbon products are promoted, analysis of each particular product’s GHG emissions and carbon footprint (CF) is needed. As an alternative to fossil fuels, renewable fuels seem to present a promising scenario. The use of biofuels promotes reduced emissions of greenhouse gases and reduces the related detrimental impact of transport. Biofuels are considered as low carbon-emitting alternatives to conventional fuels. It is possible to mitigate environmental damage by promoting renewable or alternative fuels, namely biofuels, solar energy, biomass, wind, geothermal, small-scale hydro, and wave power. Fossil fuels are typically used to operate farm machines, contributing to carbon emissions and accelerating climate change. Agriculture is the foremost source of food for humans. ![]()
