TEST REVIEW Resources and Energy Energy Types

TEST REVIEW Resources and Energy

Energy Types: Can you match and discuss the +/- ? • • • Chemical Electrical Mechanical Light (EM) Nuclear Heat • Clean • Renewable • Sustainable • • • Wind Geothermal Active Solar Biomass Passive Solar Coal, Oil, Natural Gas Hydrogen Fuel Cells Hydroelectric Tidal

Resources ≠ Reserves • Resources – amounts of material that are known/ assumed to exist that can be extracted NOW or in the FUTURE for a POSSIBLE profit $ • Reserves – known amounts of material that can PRESENTLY be extracted for a PROFIT – “proven”

Matter Cycles, Energy Flows Global Warming Acid Rain Smog Burning Coal = CO 2 + SO + H 20 + Ash + (Cx. Hx. Sx. Ox) Light + Noise + Heat Example of the Laws of Conservation of Matter and Thermodynamics

Solar Energy

Photovoltaic Cells • Life is carbonbased for a reason 1. Sunlight strikes semi-conductor 2. Electrons move 3. Energy can be stored in battery • Silicon atoms have the same capabilities http: //www. youtube. com/watch? v=K 76 r 41 ja. GJg (1: 07 mins)

How does a turbine generate electricity? What can be used to turn a turbine (which traditional/nonrenewable and renewable sources)? • Turbines generate electricity the turbine spins, which spins a magnet within metal. Electrons from the metal atoms are affected by the magnet and are harnessed. • Nonrenewables that turn steam from boiling water, that was boiled by burning: coal, oil, natural gas or nuclear fission • Renewables that turn falling water, wind, tides, water boiled by: the sun, burning biomass/fuel/gas, geothermal energy
