Sources of Energy

What’s the link between fossil fuels and Earth’s ‘fever’?

• Fossil fuels cool the Earth by reflecting sunlight.

• CO₂ traps heat = global warming! 🌡️

• Fossil fuels have no impact on Earth's temperature.

• Fossil fuels are a renewable energy source.

How is a wind turbine the opposite of a fan?

• Turns kinetic → electrical (not electrical → kinetic)! 🌬️⚡

• Turns electrical → kinetic (not kinetic → electrical)! 🌪️🔌

• Both convert kinetic energy into thermal energy.

• Both generate electricity from wind energy.

Why is switching to renewables like upgrading your phone?

• Faster, cleaner, no guilt! 📱♻️

• More expensive and complicated.

• Less efficient than fossil fuels.

• Requires more maintenance and care.

Spot the error: ‘Hydropower burns water for fuel.

• True! Hydropower burns water for fuel.

• False! Flowing water spins turbines. 💦🌀

• Hydropower uses coal as fuel.

• Hydropower generates energy by burning fossil fuels.

Why are fossil fuels like a one-time phone battery?

• They are renewable resources.

• They have an unlimited supply.

• Limited supply + toxic waste! ⛽🔋

• They are environmentally friendly.

What’s the energy change in a coal power station?

• Chemical → electrical → kinetic → heat

• Chemical → heat → kinetic → electrical! 🔥🔄⚡

• Kinetic → chemical → electrical → heat

• Electrical → kinetic → chemical → heat

List 4 renewables and their superpower

• Wind 🌬️, solar ☀️, hydro 💧, geothermal ♨️ → Clean + unlimited!

• Coal ⛏️, oil ⛽, natural gas 🔥, nuclear ⚛️ → Non-renewable resources!

• Biomass 🌱, tidal 🌊, wave 🌊, hydrogen ⚡ → Sustainable but limited!

• Wind 🌬️, solar ☀️, fossil fuels ⛽, geothermal ♨️ → Clean but finite!

How is sunlight the OG influencer?

• Solar panels turn its ‘likes’ into electricity! ☀️⚡

• Sunlight provides warmth and comfort to living beings.

• Sunlight is essential for photosynthesis in plants.

• Sunlight influences weather patterns and climate.

Why is your phone charger a fossil fuel spy?

• Because it uses renewable energy sources.

• If your grid uses coal, so does your charger! 🔌⛽

• It has a built-in solar panel.

• It only charges when connected to a wind turbine.
