1 First Edition Biofuels Biogas/Biomass

2 What Are Biofuels?

3 Section 1 What are biofuels? Biomass is when you burn a fuel or waste to heat water to make steam to make electricity. Biofuel is a fuel that is made from plant oil and algae that is made into bioethanol and biodiesel. Biogas is a biofuel but made differently and uses different ingredients. 2

4 How It s Created

5 Section 1 Creation Biomass Biomass, An Example Of Biomass Would Be Wood, When The Tree Is Fully-grown It Is Cut Down To Be Biogas Biogas, a mixture of methane and hydrogen and is produced by bacteria. The biodegradable material is put in a tank for, anaerobic digestion by the bacteria, then storage and Distribution. Used As A Fuel. The Wood Is Burned To Heat The Water, The Steam Then Turns The Turbines, And The Generator Is Powered, Creating Electrical Power. Biofuel Biofuels, Corn, Sugar cane, Soya, Rapeseed and Palm Oil. Rapeseed contains oil that can be processed into Biodiesel; Sugar Cane sugars can be fermented into Bioethanol; Algae s lipids can be processed into Biodiesel. 4

6 Advantages of Using Biofuels

7 Section 1 Advantages of Using Biofuels Biomass: o It just overall makes sense to use any waste materials that we can to produce energy. o Less fossil fuels needed. o The price tends to be cheap. Biogas: o Makes sense to use unused waste materials when needed. o Fairly cheap fuels o Methane gas that comes from the waster would go up into the atmosphere. Methane is worse than CO2 being a greenhouse gas. Biofuels: o Less fossil fuels needed. o Production of biofuels makes it closer to being carbon-neutral than using fossil fuels. 6

8 Disadvantages of Using Biofuels

9 Section 1 Disadvantages of Using Biofuels Biofuels: o Greenhouse gases are still a problem Biomass: o Growing or collecting the needed fuel in the right amount can be difficult. o We have to still burn biogas, so greenhouse gases are still a problem. o Some of the stuff needed is not available year round. Biogas: o Greenhouse gases are still a product because we burn biogas. 8

10 Environmental Impact Every energy source has an environmental impact. Positive or negative there is always at least one.

11 Section 1 Environmental In order to get biofuels from crops you have to plant them, obviously. In order to get the amount of biofuels we need you need to plant a lot of crops that takes up a lot of land. This takes away the land that can be used to farm food for human consumption. Impact Negative A negative effect of biofuels is that getting them contributes the greenhouse effect. When you burn the fuels it produces greenhouse gases that pollute the air and contributes to global warming. Positive A positive impact is that we won t need fossil fuels. Biofuels do the same thing as fossil fuels but don t require going underground and taking away things that have taken millions of years to create away from the earth. 10

12 Is This a Good Energy Resource?

13 Section 1 Is This a Good Energy Resource? Biomass No And Yes Because It Is Renewable But At The Same Biogas This is chemicals and waste that is digested by bacteria due to lack of oxygen. The ending material differs depending on what materials you started with such as if you start with wood the final material would be hydrogen, carbon monoxide, methane. Biogas is also used in cars so that is good. But this also is made from waste from humans and is used to power houses and cars. Plus landfill rubbish sites decompose and make methane gas. So in conclusion this is a cheap resource that can be produced rapidly so humanity should pursue this resource. Time It Does Just As Much Damage To The Atmosphere As Fossil Fuels Because We Burn It And It Produces Greenhouse Gases. Plus It Takes Up Space That We Could Be Using For Crops That We Eat. It Is Cheap So It Wouldn t Cost As Much As Fossil Fuels. But In All Fairness Humanity Should Not Pursue This Resource. 12
