Should we switch to solar energy

1. SHOULD WE SWITCH TO SOLAR ENERGY? Ha Quynh Chi, Do Huyen My Week 4

2. TABLE OF CONTENT The introduction of solar power 1 2 3 Why should we switch to solar power? Conclusion

3. I. The foundation of solar power In 1954 , solar panels were invented and silicon - based The creation was celebrated as the dawn of a new era First commercially sold solar cell cost around $300 per watt, => It would cost well over a million to buy a unit large enough to power a single home

4. Why should we switch to solar power?

5. Good for your wallet Solar power used to be expensive but nowadays in many countries solar is the cheapest form of energy A wise financial decision that offers long-term savings. Generate electricity that reduces reliance on traditional energy To startup, installing may take you $12,000 Solar panels usually last for 25 to 30 years before losing efficiency => 8 years to be refunded and 17 to 22 years of savings on energy costs

6. Solar power vs fossil fuel Renewable energy sources have become cheaper than fossil fuel-generated electricity because: Technological advancements Declining costs of materials A better understanding of the true costs of fossil fuels Supportive government policies: tax credits and rebates Increased demand

7. Environmental Benefits Solar energy doesn’t only help reduce your electricity bills; it also has huge benefits for our planet.

8. Fossil fuels Solar energy Reduce greenhouse gas emissions release high level of pullutants free, renewable, and infinite

9. Compared to solar energy, coal contributes over 16 times the amount of CO2 emissions, while natural gas contributes over 7 times the amount of CO2 emissions.

10. Use less water Traditional electricity uses thousands of liters of water each year. Solar energy uses no water.

11. Reduce the risk of oil spills

12. Slow down climate change Solar power produces no greenhouse gases. Environmental impact of solar energy is minimal compared to that of fossil fuel energy.

13. The shift towards solar energy is a key step towards achieving energy independence.
