THE EARLY DAYS
Back in 2000, renewable energy was a niche curiosity. Solar panels cost over $10 per watt, wind turbines were rare giants, and most countries got less than 2% of their electricity from clean sources. The fossil fuel dominance seemed unshakeable.
THE SOLAR TURNING POINT
By 2010, everything changed. Chinese manufacturing drove solar costs below $2 per watt. Germany's feed-in tariffs proved the model. Wind farms spread across Europe and the US. The inflection point was clear—renewables were no longer experimental.
💡 Key insight: When solar crossed $2/watt, adoption went exponential
PARIS AGREEMENT MOMENTUM
The 2015 Paris Agreement accelerated everything. Corporations made 100% renewable pledges. Battery storage costs plummeted. Offshore wind proved viable in the North Sea. Investment flooded in—$300 billion annually by 2018.
COVID GREEN RECOVERY
Despite the pandemic, 2020 saw record renewable installations. The EU's Green Deal, China's carbon neutrality pledge, and corporate RE100 commitments created unstoppable momentum. Solar became the cheapest electricity in history in many markets.
📉 2020: Solar LCOE dropped to $0.037/kWh—cheaper than new coal!
THE NEW NORMAL
Today, renewables generate over 30% of global electricity. Solar and wind dominate new capacity additions. Storage solves intermittency. The question is no longer "if" but "how fast"—net-zero by 2050 requires tripling current capacity by 2030.
