Fossil Fuels - The Ancient Energy🦖
- Types: Crude oil (petroleum), coal, natural gas.
- Composition: Crude oil is a jumble of hydrocarbons + some organic compounds containing nitrogen, sulfur, oxygen, and a sprinkle of other elements.
- Usage: Mostly for electricity (power stations) and running cars.
- Real-world example: It's like using a vintage gramophone when everyone's moving to Spotify. It's cool, but not forever!
Global Concerns🌏
- Growing appetite for energy = more fossil fuel munching.
- Governments are saying, "Okay, we need some new tunes!", trying to shift to renewable energy. But, just like changing a music playlist, it takes time.
Burn, Baby, Burn! (But there's a cost)🔥
- Burning fossil fuels = 🌬️ lots of CO2.
- CO2 is a sneaky one, acting like a blanket trapping heat (greenhouse effect). Imagine wearing a winter jacket in summer; Earth feels that too!
What's in the Air?🌌
- Air's main ingredients: Nitrogen (N2) ~78% and Oxygen (O2) ~21%.
- CO₂, though just 0.04%, plays a significant role because it's like that one party guest who changes the vibe.
- How? CO2 absorbs infrared rays, dances a bit (vibration), then throws that energy back, some towards Earth = Earth's temperature 🔺.
Other Culprits🤔
Methane, nitrous oxide, water vapour, and some fancy stuff like hydrofluorocarbons. Think of them as CO2's sidekicks in the warming game.
