2. The benefits Renewable unlike fossil fuels
Release lower levels of carbon dioxide and other emissions when burnt compared to fossil fuels(greenhouse gases)
Is useful in farms, and there is a lot of farms in Carnation/Duvall so excessive waste needs to be disposed
Vegetable oils used in some restaurants such as, IXTAPA can be used and turned into Ethanol
Ethanol a form of alcohol that’s caused by fermenting plants/trees/crops with yeast is cheaper than diesel and gasoline
Can create jobs for others
Cost less than nuclear energy

3. The disadvantages
Uses field waste which some people believe that should be used as food instead of power
When used in cars it can create engine problems
It has low energy so you would need to stop and refuel frequently (also expensive)

4. Limitations and solution
When Winter occurs the farms cant grow their crops and create the fuel for the biofuel generators.
Fix
Before Winter the farms can stock up on ethanol in silos. Also us farmers could feed their livestock laxatives and use their manure. (laxatives=more poop)
