Resources
What is a resource? definition: any physical or virtual entity of limited
availability that needs to be consumed to obtain benefit from it
biotic: plants, animals and their products abiotic: non-living matter, minerals not from organic
matter
What is the difference between a limited resource and a renewable resource? one takes a LONG time to form (geological periods),
other can be replenished or reproduced easily

Developing/using renewable resources
Why might we want to use renewable resources more widely? continuously available easily available made in large quantities
How can we get/create renewable resources?

Types of Biofuels
Bioalcohols: alcohols synthesized chemically or biologically, have high octane rating (which means they can ignite well) but lower energy density

Types of Biofuels
Biogases: gases produced by biological breakdown of organic matter (without O2)

Types of Biofuels
Biodiesels: clean burning alternative fuel, produced from domestic, renewable resources
How available are these types of biofuels?How efficient is each type of biofuel?
