A science policy analyst compares electric car efficiency. Model A uses 0.2 kWh/km, and Model B uses 0.15 kWh/km. If both drive 150 km, how much less energy does Model B use?

Comparing Electric Car Efficiency: How Model B Slashes Energy Use Compared to Model A When it comes to electric vehicles (EVs), efficiency is a key factor influencing range, cost, and environmental impact. A recent analysis by a science policy analyst highlights how subtle differences in energy consumption can significantly affect real-world performance—especially over long distances. Let’s take two prominent models: Model A, which consumes 0.2 kilowatt-hours (kWh) per kilometer, and Model B, which outperforms with a more efficient 0.15 kWh/km. If both vehicles drive 150 kilometers, understanding the energy savings reveals not only cost benefits but also broader sustainability impacts. ### Energy Usage Comparison
