Environmental Science Energy Resources and Consumption quiz

📚 Quick Study Guide

• ☀️ Renewable Energy: Energy from sources that are naturally replenished, such as solar, wind, and hydropower.
• 💨 Non-Renewable Energy: Energy from finite sources that cannot be replenished on a human timescale, such as fossil fuels (coal, oil, natural gas) and nuclear energy.
• 🌡️ Energy Consumption: The amount of energy used by individuals, households, industries, and countries. Measured in units like kilowatt-hours (kWh), joules (J), or British thermal units (BTU).
• 📊 Energy Efficiency: Using less energy to provide the same level of energy service. For example, using LED bulbs instead of incandescent bulbs.
• 🌍 Environmental Impact: The effects of energy production and consumption on the environment, including air and water pollution, greenhouse gas emissions, and habitat destruction.
• ⚖️ Energy Conservation: Reducing energy consumption through behavioral changes, such as turning off lights and appliances when not in use.
• 💡 Key Formulas:
  • Power (P) = Energy (E) / Time (t) -> $P = \frac{E}{t}$
  • Energy (E) = Power (P) x Time (t) -> $E = P \times t$
