Electric vehicles (EVs) and smart grids are interconnected systems that enhance energy efficiency and consumption.
Detailed Explanation
Electric vehicles (EVs) run on electricity instead of gasoline or diesel. They are part of a broader system, often referred to as a smart grid, which uses digital technology to manage and distribute electricity more efficiently. The integration of EVs into smart grids allows for better energy management, including renewable energy sources, which can help reduce greenhouse gas emissions.
Examples & Analogies
Think of it like a coordinated dance. Just as dancers must work together to create a beautiful performance, EVs and smart grids work together to optimize energy use. If one dancer performs out of sync, it disrupts the whole routine. Similarly, if EVs arenβt properly integrated into the smart grid, energy efficiency can suffer.
