GEOL 110 1st Edition Lecture 1 Outline of Last Lecture I. Review of Syllabus and Scrapbook ProcedureOutline of Current Lecture II. Mineral RecourcesA. Precious vs. StrategicB. Metallic vs. Nonmetallic III. Potential Energy Sources A.Types of EnergyB.Energy UsageIV. Other ObservationsCurrent LectureI. Mineral ResourcesA. Precious vs. Strategic1. Strategic minerals – necessary or essential for civilian, industrial, or military needs2. Precious minerals – ornamental or jewelry usageB. Metallic Minerals – gold, silver, copper, lead, zinc, iron, aluminum C. Nonmetallic – sand and gravel, gypsum, phosphate, building stone1. 94% of the minerals recources consumed in the US are nonmetallic (ex: crushed stone, sand and gravel that are used primarily in construction)2. Because of this, there are many large quarries spread across the USII. Potential Energy SourcesA. Wind, Solar, Hydroelectric, Fossil Fuels (oil and gas), Geothermal Fuel (Earth’s internal heat), NuclearThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.B. Overall, the US consumes over 4 times the amount of energy than the world average1. Per capita (per person), the US and Canada are the top energy consumersC. 83% of our energy comes from non-renewable sources (coal, gas, oil)D. Types of Energy1. Petroleum – most widely used (37%)2. Natural Gas (25%)3. Coal (21%)4. Nuclear Electric Power (9%)5. Renewable Energy (8%)a. Different types of renewable energy - Hydroelectric power (35%), Wood (24%), Biofuels (20%), Wind (9%), Waste (6%), Geothermal (5%), Solar (1%)E. Energy Usage1. Industrial (31%) – has the potential to increase energy usage efficiencya. Uses petroleum, natural gas, coal, and renewable energyb. Has the most source diversity (uses all sources fairly equally)2. Transportation (28%)a. Uses mainly petroleum, with little natural gas and renewable energy3. Residential (22%)a. Primarily uses natural gas, with some coal, petroleum, and renewable energy4. Commercial (19%)a. Primarily uses natural gas, with some coal, petroleum, and renewable energy5. Electric Power demands primarily coal usage, with some natural gas use and little petroleum or renewable energy usage. This is the only area that uses Nuclear Electric Power.III. Other ObservationsA. Ending dependence on foreign oil and development of renewable energy sources seem unrelated. Instead of buying abroad, more oil options are being considered within US bordersB. The US was self-sufficient in energy until the late 1950’s when energy consumption began to outpace domestic production. C. However, the energy consumed to produce a dollar’s worth of output goods continues to decline as the economy becomes more efficient. We are about 20% more efficient per person than in the last 30
