📖 Type: Informative Article / Essay
🎯 Theme: Environment 🌿, Energy 🔋, Science and Future Technologies 🚀

📖 Long Summary / Explanation:

Aaj duniya bhar mein vehicles aur factories chalane ke liye fossil fuels (coal, petrol, diesel) ka use hota hai. Lekin ye fuel:

• Tezi se khatam ho rahe hain
  
  

• Pollution badha rahe hain
  
  

• Environment ko destroy kar rahe hain
  
  

Writer kehti hain ki hume clean and renewable sources of energy chahiye jo future ke liye safe ho.

⚡ Alternatives to Fossil Fuels:

🌞 1. Solar Power

☀️ Suraj ki roshni se energy milti hai.
✅ Pros: Free, unlimited, pollution-free
❌ Cons: Raat mein ya badal hone par kaam nahi karta

💨 2. Wind Power

🌬️ Windmills hawa se electricity banate hain
✅ Pros: Renewable, no pollution
❌ Cons: Sirf windy areas mein kaam karta hai

🌊 3. Hydropower

💧 Pani ke dam se electricity generate hoti hai
✅ Pros: Powerful and renewable
❌ Cons: Dams banana expensive hai

🛢️ 4. Bio-fuels

🌾 Ganne, soya, ya corn se banaye jaate hain
✅ Pros: Farmers ke liye bhi faydemand
❌ Cons: Food production kam ho sakta hai

🔋 5. Hydrogen Fuel Cells

🚗 Hydrogen ko use karke electricity banayi ja sakti hai
✅ Pros: Pollution-free cars possible
❌ Cons: Bohot costly technology abhi tak
