Study Notes
Energy
Renewable Energy
- Definition: Energy sourced from natural processes that are continuously replenished.
-
Types:
- Solar Energy: Captured from sunlight using solar panels.
- Wind Energy: Generated from wind using turbines.
- Hydropower: Produced from the movement of water in rivers or dams.
- Biomass: Energy from organic materials, including plant and animal waste.
- Geothermal: Utilizes heat from beneath the Earth’s surface.
-
Benefits:
- Reduces greenhouse gas emissions.
- Low operational costs once installed.
- Enhances energy security and independence.
Energy Efficiency
- Definition: Using less energy to perform the same task or produce the same output.
-
Key Concepts:

- Building insulation and design that minimize energy use.
- Industrial processes optimized for lower energy consumption.
-
Benefits:
- Saves money on energy bills.
- Reduces demand for energy production, lessening environmental impact.
- Can lead to job creation in the efficiency sector.
Energy Conservation
- Definition: The practice of reducing energy use, often through behavioral changes.
-
Methods:
- Turning off lights and electronics when not in use.
- Using public transport or carpooling instead of individual car travel.
- Reducing heating and cooling usage through smart thermostats.
-
Benefits:
- Lowers energy costs and environmental footprint.
- Encourages sustainable habits and awareness around energy use.
Fossil Fuels
- Definition: Natural substances formed from ancient organic matter, primarily used for energy production.
-
Types:
- Coal: Solid fossil fuel used primarily for electricity generation.
- Oil: Liquid fossil fuel used for transportation and heating.
- Natural Gas: Gaseous fossil fuel used for heating, electricity generation, and as industrial feedstock.
-
Impacts:
