SOLAR POWER INVENTED IN 1960 CHINA MASS PRODUCTION 1975

**Switzerland began nuclear power in 1969 with Beznau, expanded in the 1970s, while solar power milestones include the 1961 UN energy conference, the first electricity‑generating wind turbines in the late 19th century, and China’s solar panel mass production starting in 1975.** --- ## ⚡ Clean Power Timeline ### 🇨🇭 Switzerland – Nuclear Power (1970s) - **1969**: Beznau Unit 1 (365 MW) became Switzerland’s first commercial nuclear plant. - **1971–72**: Beznau Unit 2 followed. - **1973–79**: Gösgen Nuclear Power Plant built, operational in 1979 (920 MW). - Nuclear expansion in the 1970s was driven by the **oil crisis** and the need for domestic, low‑carbon baseload power. [grokipedia.com](https://grokipedia.com/page/Nuclear_power_in_Switzerland) [grokipedia.com](https://grokipedia.com/page/Beznau_Nuclear_Power_Plant) --- ### ☀️ Solar Power – Early Milestones - **1954**: Bell Labs created the first practical silicon solar cell (6% efficiency). - **1960**: Hoffman Electronics achieved 14% efficiency. - **1961**: UN “New Sources of Energy” conference in Rome highlighted solar, wind, and geothermal as future energy sources.

[peterschulte.org](https://peterschulte.org/good-news/china-domestic-solar-cell-production-1975/) - Production was initially tiny (0.5 kW installed capacity), but it seeded the industry. - **1983**: First 10 kW civil PV station built in Gansu Province. [energytrend.com](https://www.energytrend.com/news/20240520-47063.html) - **2002**: Suntech Power launched a 10 MW production line, marking the beginning of China’s large‑scale solar manufacturing boom. [World Energy](https://www.world-energy.org/article/32767.html) --- ## 📊 Quick Comparison | Technology | First Key Date | Location | Significance | |------------|----------------|----------|--------------| | Nuclear (Switzerland) | 1969 | Beznau | First Swiss nuclear plant, expanded in 1970s | | Solar (Global) | 1961 | UN Rome Conference | Solar recognized as future energy | | Wind (Global) | 1883–1888 | Austria, Scotland, USA | First electricity‑generating wind turbines | | Solar (China) | 1975 | Ningbo & Kaifeng | Start of mass production, later global dominance | --- ✅ **Takeaway:** Switzerland’s clean power story began with nuclear in 1969, while solar and wind had earlier global roots. China’s solar industry started modestly in 1975 but grew into the world’s largest producer by the 2000s.
