Solutions & Pathways

Accelerate solar + wind installations: These account for ~95 % of renewable capacity growth through 2030 .

Promote  energy storage & grid flexibility (Battery & pumped hydro)

Adopt carbon pricing & clean energy policies (e.g. EU solar leadership, CO₂ taxation)

Support R&D and innovation, especially in emerging technologies like geothermal, hydrogen, biomass

Suggested Roles : Renewable Energy -Green Energy

Students:

Join campus green clubs

Advocate for solar panels at school

Use energy‑saving methods  and social media to educate peers.

Aware your parents about Renewable energy and aware public .

Participate in debate related to energy saving etc.

Participate in plantation campaign .

Support green and save energy .

Schools:

Install rooftop solar

Hold renewable energy awareness events

Integrate hands‑on projects (like mini-wind turbines) into STEM curriculum

Educate people and students about Renewable energy .

Organize debate or such events .

NGOs:

Run community solar or wind initiatives

Lobby local authorities for renewables-friendly policies

Organise public workshops

Public:

Choose green energy tariffs

Install rooftop solar or small wind

Reduce energy consumption (LEDs, smart meters, EVs)

Summary

Renewable energy—including solar energy, wind energy and other green energy sources—is scaling rapidly worldwide. With strategic investments and policies, it can meet nearly half of global electricity by 2030. Major powers like China, India, the EU and Brazil lead the transition.

Conclusion

Yes—renewable energy can save our planet if global coordination accelerates capacity deployment, grid infrastructure and supportive policy. It’s a realistic route to decarbonise, improve energy security, and empower communities worldwide.

FAQs

1. Is renewable energy really renewable?
   Yes. It’s drawn from natural flows like sun, wind and water, which replenish continuously.
2. Can solar & wind fully replace fossil fuels?
   By 2030 they can provide nearly half of global electricity; with storage and policy, full replacement is possible by mid-century.
3. Which country leads in capacity?
   China leads with ~1,878 GW of renewables; China and EU together produce ~32 % of global renewable electricity .
4. How much did solar grow in 2023?
   Solar added 346 GW in 2023—nearly 73 % of all new renewable additions .
5. What share of energy is renewables in India?
   India had ~46 % renewable energy capacity share and reached 50 % non‑fossil capacity by early 2025 .
6. Are renewables cost‑effective?
   Yes. Costs of solar and wind energy or panel is decreasing continuously  due to scale and innovation.
7. What supports storage growth?
   Battery systems, pumped hydro (e.g. Himalayan projects), grid modernization.
8. Can students make real impact?
   Absolutely—via awareness, advocacy, projects, and daily energy-saving choices.
9. What policies speed transition?
   Carbon pricing, green tariffs, investment incentives, research funding.
10. Will renewables reduce emissions?
    Yes—scaling them replaces fossil generation and cuts CO₂ emissions significantly.
11. How to make renewables equitable?
    Community solar, subsidies for low-income households, public‑private partnerships.
12. Can renewables provide base‑load power?
    Combined with storage and dispatchable sources (hydro, biomass, nuclear), yes.
13. What’s the role of hydrogen?
    Green hydrogen, made using renewable energy, acts like a clean fuel battery—it can store excess energy and help reduce carbon emissions in industries and transportation.
14. Is geothermal a significant source?
    Currently smaller (~1 % share), but growing, especially in geologically active regions .
15. How fast should renewables grow?
    Global capacities must nearly triple by 2030 to meet 1.5 °C goals; current growth falls short without policy boost .
