Which kind of cars does not harm the environment؟
إجابة الطالب المختصرة من خلال موقع بوابة الإجابات هي
a- Hybrid car
No car *completely* avoids harming the environment, as even electric vehicles have an environmental footprint associated with their production, battery manufacturing, and electricity generation. However, some car types are significantly better for the environment than others. Here's a breakdown:
* **Electric Vehicles (EVs):** These are generally considered the most environmentally friendly option because they produce zero tailpipe emissions. The environmental impact is mostly shifted to the electricity generation source. If the electricity comes from renewable sources (solar, wind, hydro), the overall impact is much lower. Even with electricity from fossil fuels, EVs are often cleaner than gasoline cars due to the greater efficiency of power plants compared to internal combustion engines.
* **Plug-in Hybrid Electric Vehicles (PHEVs):** These cars combine an electric motor and a gasoline engine. They can drive on electric power for a certain range before switching to gasoline. This reduces emissions compared to a traditional gasoline car, especially if the vehicle is frequently charged and used primarily in electric mode.
* **Hybrid Electric Vehicles (HEVs):** These cars use a gasoline engine assisted by an electric motor. They cannot be plugged in and have a smaller battery than PHEVs, so they can only drive short distances on electric power alone. However, they still offer better fuel economy and lower emissions than traditional gasoline cars.
* **Hydrogen Fuel Cell Vehicles (FCVs):** These cars use hydrogen to generate electricity, producing only water vapor as a byproduct. However, the production and distribution of hydrogen can be energy-intensive and may involve fossil fuels, depending on the source. The environmental impact of FCVs depends on the sustainability of the hydrogen production process.
It's essential to consider the full life cycle of a car when assessing its environmental impact, including manufacturing, use, and disposal. For example, the production of batteries for EVs can be resource-intensive and have environmental consequences. Similarly, the mining and refining of gasoline have significant environmental impacts.
So, to directly answer your question: No car perfectly avoids harming the environment, but Electric Vehicles (EVs), particularly when powered by renewable energy sources, are the least harmful option currently available.
