    Study Notes

    Nuclear Energy

    • The Chernobyl nuclear disaster was the worst in history
    • The accident occurred in Ukraine in 1986

    Renewable Energy

    • Renewable resources are likely to become increasingly attractive because of concerns about fossil fuel depletion and environmental impact
    • Renewable resources offer energy diversity, cost-competitiveness and a cleaner environment

    Types of Renewable Energy

    • Continuous sources, will never run out:
      • HEP (Hydroelectric Power)
      • Solar
    • Flow sources are sustainable if managed carefully:
      • Biomass (including fuel wood)

    Hydroelectric Power

    • Water availability is essential for hydroelectric power
    • Hydroelectric power can have negative environmental effects:
      • Reservoir creation can displace people and wildlife
      • Reservoirs can become acidic and anaerobic
      • Dams can be a flood risk and can trap silt

    Wind Power

    • Wind farms are most effective in areas with strong, steady winds
    • Wind energy is a potentially infinite and pollution-free source of energy
    • Wind farms can be costly to manufacture and implement

    Solar Power

    • The sun is the Earth's primary energy source
    • Solar panels capture sunlight and convert it into electricity
    • Solar panels can be costly to manufacture and implement

    Wave Power

    • Waves are created by wind transferring energy over the water
    • Wave power uses the movement of seawater to drive turbines

    Factors Affecting Energy Demand

    • Changes in price: the relative cost of different energy sources can influence demand
    • Environmental factors and public opinion: public awareness of environmental impacts can influence government decisions

    Energy Policy

    • Energy policy addresses energy production, distribution, and consumption
    • Policy tools include legislation, incentives, conservation measures, and taxation

    Brazil's Energy Landscape

    • Brazil is a significant oil and gas producer in South America, and the world's second-largest ethanol producer
    • Brazil's energy sector underwent market liberalization in the late 1990s and early 2000s
    • Government policies focus on increasing energy efficiency and renewable energy sources
    • Brazil is the world's 12th largest oil producer
    • Brazil has the second-largest proven oil reserves in South America
    • Brazil has significant natural gas, coal, and oil shale resources
    • Brazil has the sixth-largest uranium reserves in the world

    Environmental Degradation

    • Environmental degradation is any harmful change to the environment
    • Natural causes of degradation include erosion, landslides, forest fires, and floods
    • Pollution is a major contributor to environmental degradation
    • Pollution impacts human health, with significant variations in death rates from air pollution globally
    • Land pollution includes landfills, mine waste, and contaminated soil
    • Water pollution includes industrial wastewater, sewage, agricultural runoff, and thermal changes
    • Air pollution includes emissions from industries and fossil fuel burning

    Water Scarcity

    • Water is essential for life and human activities
    • Water scarcity is a major global environmental problem
    • Water scarcity can affect food security, economic development, and social stability

    The London Docklands Redevelopment
