| Basics of Biofuel | Advantages of Biofuels | Disadvantages/Concerns of Biofuel | How do Biofuels Work? | 
|---|---|---|---|
| 
						
					 
					  What is biofuel?					 
					
					 A renewable fuel derived from organic materials such as plants or animal waste, used as an alternative to fossil fuels. 
					 | 
				
				
						
					 
					  What is one pro-environment property that biofuels have?					 
					
					 Biofuels are biodegradable; Biofuels create less greenhouse gas emissions 
					 | 
				
				
						
					 
					  What is deforestation?					 
					
					 This environmental concern related to biofuels arises when large areas of land are cleared for their production. 
					 | 
				
				
						
					 
					  What is fermentation?					 
					
					 This organic process, often conducted by microorganisms, transforms biological materials like plant sugars into biofuels. 
					 | 
						
| 
						
					 
					  What are ethanol fuel mixtures?					 
					
					 In the context of cars, E30 means that it accepts 30% blended bio-ethanol gasoline, a fuel mixture of 3:7 bio-ethanol to gasoline 
					 | 
				
				
						
					 
					  What are some reasons why biofuels are cleaner than fossil fuels?					 
					
					 Biofuels have and use less carbon; Biofuels are carbon neutral; Biofuels produce fewer air pollutants when combusted. 
					 | 
				
				
						
					 
					  What is the competition with food crops?					 
					
					 One of the drawbacks of using biofuels is that they can compete with this vital global resource, leading to increased food prices. 
					 | 
				
				
						
					 
					  What is hydrolysis?					 
					
					 In the production of biofuels, this chemical process is used to break down complex organic molecules into simpler compounds that can be further converted into biofuels. 
					 | 
						
| 
						
					 
					  What are 1st, 2nd, 3rd, and 4th generation biofuels?					 
					
					 Different kinds of biofuels that are categorized by energy efficiency, cost, waste, etc. in 4 tiers/generations. 
					 | 
				
				
						
					 
					  What impact do biofuels have on economies?					 
					
					 Biofuel and related industries create jobs, reduce energy imports, diversify energy sources, and provide rural development. 
					 | 
				
				
						
					 
					  What is the problem of land-use change?					 
					
					 When biofuels are produced from certain crops like corn or sugarcane, this issue can occur, where valuable farmland is diverted from food production to fuel production. 
					 | 
				
				
						
					 
					  What is biodiesel?					 
					
					 This biofuel is more combustible, contains less carbon, is sourced from animal and plant esters, and has a lower energy density than its fossil fuel equivalent.
