A science journalist is creating a data visualization showing the rise in global renewable energy usage. The usage increased by 8% annually over the past 5 years, starting from 200 terawatt-hours. What is the total renewable energy usage after 5 years? (Round to the nearest whole number.)

Why this trend matters now: Clean energy is no longer a niche topic. With growing climate concerns, policy shifts, and rising public awareness, governments and communities worldwide are tracking energy transformations closely. The steady growth in renewable usage reveals how far progress has come—and what remains to be achieved.

Why This Trend Is Gaining US Attention

The rise in renewable energy is gaining traction globally—and especially in the United States—due to converging economic and environmental drivers. Rising fossil fuel costs, advancing technology, and strong government incentives have accelerated adoption across industries. In the US, clean power is increasingly seen not just as a sustainability goal, but as a strategic economic opportunity. Public interest in energy independence and climate resilience continues to grow, making visual storytelling around these trends both relevant and timely.

How the Numbers Tell the Full Story

Starting at 200 terawatt-hours five years ago, an 8% annual increase compounds each year. With no compounding effect error here—simply cumulative growth—the calculation unfolds clearly:

Year 1: 200 × 1.08 = 216
Year 2: 216 × 1.08 = 233
Year 3: 233 × 1.08 = 251
Year 4: 251 × 1.08 = 271
Year 5: 271 × 1.08 = 293

So after five years, total renewable energy usage reaches approximately 293 terawatt-hours. This rounded figure reflects real-world data patterns closely and sets a solid baseline for visualizations on long-term energy shifts.

Common Questions About the 5-Year Slide

Q: What counts as “renewable” energy here?
Renewables include solar, wind, hydroelectric, geothermal, and bioenergy—sources replenished naturally and reducing carbon emissions.

Q: Why Irene rounding to the nearest whole number?
Precision matters in communication; rounding produces a clean, memorable number while preserving overall accuracy.

Q: Is this growth consistent every year or fluctuating?
