Cost-Benefit Analysis of Renewable Energy: AP Environmental Science Exam Prep

📚 Quick Study Guide

• 🌍 Renewable Energy Sources: Solar, wind, hydro, geothermal, and biomass. These sources replenish naturally and have lower carbon emissions compared to fossil fuels.
• 💰 Cost-Benefit Analysis (CBA): A systematic approach to estimating the strengths and weaknesses of alternatives used to determine options which provide the best approach to achieving benefits while preserving savings. It involves comparing the total expected cost of each option against the total expected benefits.
• 📈 Economic Costs: Initial investment, maintenance, land use, and grid integration.
• 🌱 Environmental Costs: Habitat disruption, visual pollution, and potential impacts on wildlife.
• ⚡ Economic Benefits: Reduced fuel costs, job creation in the renewable energy sector, and energy independence.
• 🌳 Environmental Benefits: Lower greenhouse gas emissions, reduced air and water pollution, and conservation of natural resources.
• 📊 Formulas & Metrics:
  • Net Present Value (NPV): $NPV = \sum_{t=0}^{n} \frac{CF_t}{(1+r)^t}$ where $CF_t$ is the cash flow at time t, r is the discount rate, and n is the number of periods.
  • Levelized Cost of Energy (LCOE): $LCOE = \frac{\text{Total Lifecycle Cost}}{\text{Total Energy Produced}}$
