  1. Energy Resources and use New Mexico climate champions

  2. Phenomenon • Human behavior is changing the Earth’s atmosphere and affecting the climate. Energy Audit Insulating You, Insulating Earth

  3. Two main groups of energy Renewable Non-renewable REPLENISHED AND CONSUMED AT A SIMILAR RATE CONSUMED FASTER THAN IT IS REPLENISHED • Ex. Coal, Natural Gas, Petroleum Oil • Production and use emit more greenhouse gases • Unsustainable long-term • Ex. Solar, Wind, Hydroelectric, Geothermal, Biomass • Production and use emit less greenhouse gases • Sustainable long-term

  4. Activity • Every bag of 100 energy beads represents a country. • Each country has a different number of renewable (green) and non-renewable (orange) energy beads. • These represent the percentage of renewable and non-renewable resources used for each country’s total energy consumption.

  5. Part 1: Constant energy consumption • Renewable = green beads • Non-renewable = orange beads • Remove 10 beads each round (year). • Renewables can go back into bag, but non-renewables cannot. • Stop after five years.

  6. procedures • Model energy consumption by removing beads from bag. • Renewables (green beads) can be put back into the bag after each year. • Non-renewables (orange beads) cannot be put back into the bag after each year. • Complete the data sheet as you move through 5 years.

  7. Part 1: whole class data

  8. Part 1: percentages of renewable and nonrenewable energy used

  9. Types of energy production Renewable or non-renewable?

  10. Two main groups of energy Renewable Non-renewable REPLENISHED AND CONSUMED AT A SIMILAR RATE CONSUMED FASTER THAN IT IS REPLENISHED • Ex. Coal, Natural Gas, Petroleum Oil • Production and use emit more greenhouse gases • Unsustainable long-term • Ex. Solar, Wind, Hydroelectric, Geothermal, Biomass • Production and use emit less greenhouse gases • Sustainable long-term

  11. Renewable or non-renewable?Solar RENEWABLE! • Radiant energy produced by the sun is harnessed for power. • Photons (particles of light) knock electrons loose, creating an electric current. Photo 1: Hatch Solar Energy Center Hatch, NM Photo 2: Noor Complex, Morocco

  12. RENEWABLE! RENEWABLE OR NON-RENEWABLE?WIND • Kinetic energy produced by wind is harnessed for power. • Wind turbines (propellers) are connected to a generator to generate electricity.

  13. Formed from the remains of dead organisms that were buried and placed under high heat and pressure. Burning fossil fuels to boil water generates steam that is used to drive large turbines that produce electricity. Renewable or non-renewable?Fossil fuels (Coal, oil, and NATURAL GAS) NON-RENEWABLE!

  15. RENEWABLE! Renewable or non-renewable?Hydroelectric • Kinetic energy in movement of water as gravity pulls it downward is harnessed for power. • Downward flow of water drives turbines that produce electricity.

  16. Renewable or non-renewable?GEOTHERMAL RENEWABLE! • Thermal energy derived from the earth is harnessed for power. • Steam from the earth is captured to drive turbines that generate electricity. Photo 1: Dale Burgett Geothermal Plant Lordsburg, NM Photo 2: The Geysers Mayacamas Mountains, CA

  17. Part 2: Increasing energy consumption WHAT IS CAUSING AN INCREASE IN DEMAND FOR ENERGY? https://www.census.gov/popclock/ Photo Source: www.worldometers.info

  18. Part 2: increasing energy consumption • Renewable = green beads • Non-renewable = orange beads • Remove an increasing number of beads each year. • Renewables can go back into bag, but non-renewables cannot. • Stop after five years OR when your demand is more than your remaining energy.

  19. Energy use and climate change The graph shows that heating degree-days (the number of days where heating is used) are decreasing. There is less need to heat buildings because temperatures outside are warmer. Cooling degree-days (the number of days where cooling is used) are increasing. There is more need to cool buildings because temperatures outside are warmer. With warmer temperatures, how will demands for energy change?

  20. Connecting energy use to our phenomenon Phenomenon: Human behavior is changing Earth’s atmosphere and affecting the climate. How does energy production and consumption relate to global climate change?
