Study Notes

Advantages of Renewable Energy

Environmentally Friendly: Reduces greenhouse gas emissions, improving air quality and combating climate change.
Sustainable: Naturally replenished resources, avoiding depletion like fossil fuels.
Energy Security: Reduced reliance on imported fuels, boosting energy independence.
Cost-Effective (Long Term): Low operational costs after initial high investment, with decreasing costs due to tech advancements.
Decentralized Production: Deployable in remote regions, providing electricity to areas without grid connections.
Diverse Applications: Powers electricity generation, transportation (e.g., EVs), and heating/cooling.
Job Creation: Generates jobs in manufacturing, installation, operation, and maintenance sectors.
Abundant Availability: Resources like sunlight, wind, and biomass are readily available (especially in diverse geographical locations).
Reduced Water Consumption: Most renewable energy systems (e.g., solar, wind) need far less water than conventional power plants.

Limitations of Renewable Energy

High Initial Costs: Significant initial investment in systems like solar farms and wind turbines.
Intermittent Supply: Many renewable sources depend heavily on natural conditions (e.g., sunlight, wind speed), requiring energy storage or backup power.
Large Land Requirements: Solar, wind, and biomass facilities require significant land, potentially causing land use conflicts.
Technological Challenges: Developing and deploying effective and affordable energy storage technologies (e.g., batteries) and grid integration systems remain areas of progress.
Infrastructure Limitations: Inadequate transmission and distribution networks impede efficient integration of renewables.
Geographical Constraints: Uneven distribution of resources - solar best in tropics, wind in coastal/hilly areas, geothermal in specific areas.
Environmental Concerns (Some): Hydropower (dam construction and ecosystem disruption) and biomass (emissions if not properly managed).
Energy Storage Challenges: Costly battery technologies are needed to store energy generated during non-peak periods.
Long Payback Period: Initial investment recovery time can be long, creating investment concerns.
Maintenance Requirements: Some systems (wind turbines, biomass plants) require frequent maintenance, especially in remote areas.
