Renewable Energy Basics

Renewable Energy

• Definition: Energy generated from natural resources that can be replenished over time
• Sources:
  • Solar energy
  • Wind energy
  • Hydro energy (from rivers, oceans, and tidal currents)
  • Geothermal energy (from heat within the Earth)
  • Biomass energy (from organic matter)
• Advantages:
  • Sustainable and renewable
  • Zero or low greenhouse gas emissions
  • Can reduce dependence on fossil fuels
• Challenges:
  • Intermittent power generation
  • High upfront costs
  • Land requirements for installations

Energy Efficiency

• Definition: Using less energy to achieve the same outcome
• Strategies:
  • Improve insulation and building design
  • Use energy-efficient appliances and lighting
  • Optimize energy use in industry and transportation
  • Implement smart grid technologies
• Benefits:
  • Reduces energy consumption
  • Lowers energy costs
  • Decreases greenhouse gas emissions
  • Creates jobs and stimulates economy

Nuclear Energy

• Definition: Energy generated from the splitting of atomic nuclei (nuclear fission)
• Advantages:
  • Zero greenhouse gas emissions
  • Relatively low operating costs
  • High capacity factor (can operate continuously)
• Disadvantages:
  • High upfront costs
  • Radioactive waste disposal challenges
  • Risk of nuclear accidents
  • Proliferation concerns

Energy Storage

• Definition: Technologies that enable the storage of energy for later use
• Types:
  • Battery storage (lithium-ion, lead-acid, etc.)
  • Pumped hydro storage
  • Compressed air energy storage
  • Flywheel energy storage
• Importance:
  • Enables the integration of intermittent renewable energy sources
  • Improves grid stability and reliability
  • Enhances energy security

Fossil Fuels

• Definition: Energy generated from the combustion of ancient plants and animals (coal, oil, and natural gas)
• Characteristics:
  • High energy density
  • Well-established infrastructure
  • Relatively low upfront costs
• Disadvantages:
  • Finite resources
  • Significant greenhouse gas emissions
  • Air and water pollution
  • Contributes to climate change
