Renewable Fuels

1
Renewable Fuels

• Biomass Wind
• Hydroelectric Hydrogen
• Solar

2
Biomass (1)

• Wood
• Dung and methane
• Dung burned directly is inefficient
• Methane produced from dung is efficient

3
Biomass (2)

• Alcohol from digestion of sugarcane or grains
• Crop residues and peat
• Cornstalks, wheat straw, bagasse
• Peat bogs

4
Hydroelectric power

• Falling water turns turbines connected to
  generators
• Must build dams

Solar power

• Passive solar power primarily for heating and
  cooling
• Active solar systems requires the use of pumps
  heating, cooling, water needs

8
Architecture that Uses Solar to its Advantage
9
Wind power

• Use wind to run turbines connected to generators
• Traditionally has been used for individual needs,
  but is now being established in wind farms

Typical Wind Farm
11
Hydrogen power

• Uses fuel cells which convert hydrogen gas to
  water
• Efficient process
