Transcript Warm-up
Warm-up • What is renewable vs. non-renewable resources? • Give examples of each! Product • Brief Summary • use the BOLDED, black text – Main bullets • Be selective! • What is the most important information? • If the bolded text has a question, answer it! • Pros & Cons Expert Groups • Oil (2 & 6) • Natural Gas (3 & 7) • Coal (4 & 8) • Uranium (5 & 9) Bell Ringer 12/1- Use regular sheet of paper today • BE in YOUR SEAT!!! • What are tar sands? See pg 697! • Pros/Cons?- Make a 3 column chart that uses up a whole piece of paper. • Energy resource/ Pro/Con • Use these as column headers What info should you have for these energy resources??? • • • • • What it is Location Advantages Disadvantages How it is made and/or how energy is obtained from it • Affordability aka cost • Environmental impacts Oil • Crude oil is smelly, yellow-black liquid – Sweet= little sulfur – Sour = a lot of sulfur • Measured in barrels • Used to make many products including: – Ink, crayons, tires, eyeglasses • Oil refinery = oil turned into useful petroleum products based on molecular weight – Gas, diesel • New laws & technology helps to reduce the impact of the drilling Oil • Pros – Used in many products – Used in many forms of transportation – Major source of energy • Cons – – – – Expensive Difficult to get Pollution Non-renewable Natural Gas • • • • Methane Tasteless, colorless, odorless gas 25% of US uses natural gas Most of the natural gas used in the US is produced in the US • Can be stored as a liquid (chilled; uses 600x less space) • Used in the manufacturing of: – Steel, glass, paper, clothing, brick, ect. Natural Gas • Pros – Modern techniques reduced area needed for drilling – Less pollution than other fossil fuels – Economical • Cons – Leaks can impact environment – Can cause deforestation (for drilling) – Non-renewable – Greenhouse gas Coal • Black/Brown sedimentary rock • Most abundant in US • Requires mining (surface or underground) – 2/3 from surface which is less expensive • • - 93% of coal is used for electricity 4 different types anthracite, bituminous, subbituminous, lignite Order of heat value from greatest to least Coal • Pro – – – – Cheap Relatively abundant Many uses Modern mining is easy • Con – Non-renewable – Creates carbon dioxide – Contributes to global warming – Burning can effect human health – Mining can be dangerous – Pollution/ environmental impact – Strip mining Uranium/Nuclear Energy • Energy in the nucleus of an atom • 2 forms of energy release – Fission: atoms are split apart to form smaller atoms, releasing energy – Fusion: atoms combine to form a larger atom releasing energy • Energy heats water, the steam moves turbines used to generate electricity Expert Groups • Wind (3 & 8 ) Stations 1 & 5 • Solar (4 & 9 ) Stations 2 & 6 • Geothermal (5 & 10) Stations 3 & 7 • Hydropower (6 & Q) Stations 4 & 8 10/10/11 • Soil – Soil WS – Land Degradation – Application of Soil WS • Energy – Hydropower Warm-Up • • • • What are tar sands? Pros and Cons What is oil shale? Pg 101 # 7 What is hydroelectric power? Pros and Cons • What is tidal power? Pros and Cons • Pg107 # 5 Pollution • Water – Point source pollution – Nonpoint source pollution • Runoff • Air – Figure 19 p110 – Global Warming • Land Resources – P112 Skills Activity Protecting Resources • Conservation • Clean Water Act (1972) – Eliminate point source pollution from industry • Safe Drinking Water Act (1974) • Clean Air Act (1970) – National Ambient Air Quality Standards • CO, SO2, O3, Pb, Nitrogen Oxides, & particulates • Caring for land resources – Compost – Recycling
