Solar, wind, and beyond — how much do you know about the clean energy revolution?
Solar, wind, and beyond — how much do you know about the clean energy revolution?
Solar PV costs have dropped roughly 90% since 2010, and China alone installed over 200 GW of solar capacity in a single year in 2023. From offshore wind farms to geothermal power plants, renewable energy is reshaping the global electricity grid faster than most people realize. This quiz covers the technologies, economics, and milestones driving the clean energy transition.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll explore solar, wind, hydro, and geothermal technologies, battery storage breakthroughs, cost trends that have made renewables cheaper than fossil fuels in many markets, and global adoption milestones from Denmark's wind leadership to China's solar manufacturing dominance.
Renewables generated approximately 30% of global electricity in 2023, with hydropower contributing the largest share at around 15%, followed by wind at roughly 8% and solar at about 5%. The share continues to grow rapidly each year.
The Three Gorges Dam in China is the world's largest power station by installed capacity at 22,500 MW. It generates roughly 100 TWh of electricity per year and spans the Yangtze River in Hubei province.
The cost of solar photovoltaic modules has dropped by about 90% since 2010, making solar one of the cheapest sources of new electricity generation in most of the world. This dramatic cost reduction is largely driven by economies of scale in manufacturing, particularly in China.
