Study Notes
Renewable vs. Fossil Fuels
- Renewable energy sources, such as solar power, are inexhaustible, unlike fossil fuels, which are finite.
- Fossil fuels contribute to global warming and climate change, whereas renewable energy is cleaner and safer.
Solar Energy
- Solar panels capture sunlight and convert it into electricity.
- Solar power is viable in many regions worldwide.
- The cost of solar panels has decreased by 80% over the past 20 years.
- A significant drawback of solar energy is its inability to function at night.
Wind Turbines
- Wind turbines offer a continuous 24/7 energy production.
- Wind turbines are cheap to operate.
- Wind turbines can be noisy.
Ground Source Heating
- Ground source heating uses heat from the earth.
- Ground source heating is a reliable option with low maintenance.
- A lot of land is necessary to heat a single home using this method, making it impractical for cities.
Hydropower
- Hydropower uses moving water to generate electricity.
- It is a safe and reliable energy source.
- Climate change can negatively impact hydropower's effectiveness.
- Droughts and reduced rainfall can lead to insufficient water to power the turbines.
