RENEWABLE/ NO ENERGY - Coggle Diagram

- - - - Renewable and Clean: Wave power is a renewable energy source as waves are constantly generated by the wind and tides. It produces electricity without producing greenhouse gas emissions, contributing to a cleaner environment.
      - Predictable: Unlike solar and wind energy, waves are more predictable, as they are influenced by factors like tides, seasons, and weather patterns. This predictability allows for more reliable energy generation and grid integration.
      - High Energy Density: Waves have a high energy density compared to other renewable sources. A relatively small area of the ocean can produce significant amounts of energy, making it a potentially efficient source.
    - - High Costs: The technology for capturing wave energy is still under development and relatively expensive. Installation, maintenance, and infrastructure costs can be substantial, limiting widespread deployment.
      - Environmental Impact: The construction and operation of wave energy devices can have environmental impacts, such as disrupting marine ecosystems, affecting fish migration, and altering coastal sediment transport.
      - Variable Power Output: Wave energy is dependent on wave patterns, which can vary over time. Calm or stormy periods may result in fluctuations in power output, making it challenging to maintain a consistent energy supply.
    - - Wave capture
      - Wave motion
      - Energy convertion
- - - - 1) Environmental impact (releases carbon dioxide (CO2) and other greenhouse gases)
        2) Price volatility
    - - 1) Is widely available in many parts of the world (extensive infrastructure)
        2) It can be used in many aspects of life and it is very easy.
- - - - Photovoltaic Cells
      - Direct Current (DC) Electricity
      - Electricity Consumption
    - - Renewable and Clean: Solar energy is renewable, meaning it can be continually replenished. It does not produce greenhouse gas emissions or air pollutants during operation, making it a clean energy source and reducing the environmental impact.
      - Cost Savings: Solar power can significantly reduce or eliminate electricity bills, especially in areas with ample sunlight. Once installed, the operating costs are minimal, primarily limited to maintenance and occasional cleaning.
      - Energy Independence: Generating electricity from solar power provides a degree of energy independence, reducing reliance on fossil fuels and centralized power systems. It can also be particularly beneficial for remote locations where connecting to the grid may be expensive or impractical.
    - - Intermittent Nature: Solar power generation is dependent on sunlight availability, which varies with weather conditions and time of day. It is not consistently available during nighttime or cloudy days, necessitating energy storage or backup power sources.
      - Upfront Costs: While the cost of solar panels has decreased over the years, the initial installation cost can still be relatively high. However, long-term savings on electricity bills can offset this investment.
      - Land and Space Requirements: Generating large amounts of solar power may require significant land area, which can be a limitation in densely populated areas. Additionally, solar panels need sufficient unobstructed space to maximize their exposure to sunlight.
- - - - Wind Turbines
      - Kinetic Energy Conversion:
    - - Intermittent Nature: Wind power generation is dependent on wind availability. Since wind speed is variable, electricity production from wind turbines can fluctuate, requiring backup power sources or energy storage systems to ensure a consistent energy supply.
      - Visual and Noise Impact: Wind farms, especially large-scale installations, can alter the aesthetic landscape, which some people may find visually intrusive. Additionally, wind turbines can generate noise, although modern designs have significantly reduced the noise levels.
      - Land and Wildlife Concerns: Wind farms require a considerable amount of land, which may compete with other land uses or affect natural habitats. They can pose risks to birds and bats if located in migration paths or important habitats, although proper siting and mitigation measures can minimize these impacts.
    - - Cost-Effective: Wind power has become increasingly cost-competitive, with declining costs of wind turbine technology and improved efficiency. It offers long-term price stability compared to fossil fuels, as wind energy is not subject to fuel price fluctuations.
      - Domestic Energy Production: Wind power reduces dependence on imported fossil fuels, enhancing energy security for countries. It promotes domestic energy production, job creation, and local economic development in regions with favorable wind resources.
      - Renewable and Clean: Wind is an abundant and inexhaustible resource, making wind power a renewable energy source. It produces no greenhouse gas emissions or air pollutants during operation, contributing to a cleaner environment and mitigating climate change.
