Introduction to Renewable Energy
Renewable energy comes from natural sources that replenish continuously
2
Solar Power
- Converts sunlight into electricity using photovoltaic cells
- Global capacity reached 1.2 terawatts in 2023
- Solar farms can power entire cities with clean energy
- Residential solar panels can reduce electricity bills by 70%
3
Wind Energy
- Wind turbines convert kinetic energy into electricity
- Offshore wind farms produce 50% more energy than onshore
- Global wind capacity exceeds 900 gigawatts in 2023
- A single turbine can power 1,500 homes annually
4
Hydropower
- Generates electricity from flowing or falling water
- Accounts for 60% of renewable energy worldwide
- Pumped-storage systems help balance grid demand
- Large dams can provide power for millions of homes
5
Future of Renewables
- Renewables projected to supply 50% of global power by 2030
- Emerging technologies include tidal and wave energy
- Energy storage solutions improving grid reliability
- Investment in renewables creates 3x more jobs than fossil fuels
