What are 2 disadvantages of biofuels?
Global Warming The biofuels, which are mostly hydrogen and carbon, burning them produce carbon dioxide, which contributes to global warming. It is true that biofuels produce less GHG emissions than fossil fuels, but that can only serve to slow global warming and not stopping or reversing it.
What is a disadvantage about biofuel production?
No fuel is perfect, and there are some biofuel disadvantages – especially if plants are grown specifically. Biofuel production is currently equivalent to just a tiny fraction of global energy demand, which means a huge amount of land, water and fertiliser is needed.
What is the disadvantage of first generation biomass and second generation biomass?
The main drawback of 1st generation biofuels is that they come from biomass that is also a food source. This presents a problem when there is not enough food to feed everyone. 2nd generation biofuels come from non-food biomass, but still compete with food production for land use.
What are problems with using biofuels?
Large-scale deforestation of mature trees (which help remove CO2 through photosynthesis — much better than sugar cane or most other biofuel feedstock crops do) contributes to soil erosion, un-sustainable global warming atmospheric greenhouse gas levels, loss of habitat, and a reduction of valuable biodiversity (both on …
Is biodiesel second generation biofuel?
Biodiesel produced by transesterification from rapeseed oil, palm oil, or other plant oils is also considered a first-generation biofuel.
Which is second generation biofuel?
Second-generation biofuels are produced from nonfood crops including the waste from food crops, agricultural residue, wood chips, and waste cooking oil . Second-generation biofuel feedstock is the nonedible byproduct of food crops.
