Renewable Fuels Biomass Wind Hydroelectric Hydrogen Solar

Use of renewables is increasing, but not huge  Worldwide energy production 10% biomass 2.2% hydro 0.7% others  Worldwide electricity production 15.9% hydro 2.8% biomass and others

Biomass  Direct burning: wood, charcoal, manure  Powering vehicles: Ethanol from corn, sugarcane, cellulose-rich plants Biodiesel from soybeans, cooking oil

Biomass  Advantages?  Disadvantages?

Typical Hydroelectric Dam Hydroelectric power

 Advantages?  Disadvantages?

Solar power  Passive solar power – primarily for heating and cooling – think window placement  Active solar systems – requires the use of pumps – heating, cooling, water needs – think solar panels

Architecture that Uses Passive Solar

Solar power  Advantages?  Disadvantages?

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

Wind power  Advantages?  Disadvantages?

Hydrogen power  Uses fuel cells which convert hydrogen gas to water  Efficient process

Hydrogen power  Advantages?  Disadvantages?
