How might solar-powered buildings and cars reduce the amount of carbon dioxide that is added to the atmosphere?

Less Fossil fuel used in powering the building for light, heat, and maybe air conditioning.

How does buying a car that gets good gas mileage might reduce the amount of carbon dioxide that is added to the atmosphere?

Each gallon of fuel a car uses creates 20 lb of carbon dioxide. A car with good gas mileage means you can drive it farther and longer on each gallon of gas, makeing you burn less fuel,whitch causes less carbon dioxide to be released into the atmosphere.

Solar-powered buildings and cars can significantly reduce the amount of carbon dioxide added to the atmosphere primarily through the use of renewable energy sources. Here's how they achieve this:

Solar-powered Buildings:
1. Electricity Generation: Solar panels installed on buildings harness sunlight and convert it into electricity, reducing the reliance on fossil fuel-powered energy sources such as coal or natural gas.
2. Grid Independence: Buildings with solar panels can generate their electricity, reducing the need to draw power from the grid, which is often fueled by fossil fuels.
3. Reduced Emissions: By relying on solar power, these buildings produce zero greenhouse gas emissions during their operation, resulting in a decrease in overall carbon dioxide emissions.

Solar-powered Cars:
1. Electric Propulsion: Solar-powered cars use electricity stored in batteries for propulsion, eliminating the need for fossil fuel-based engines that produce carbon dioxide emissions.
2. Renewable Energy Source: Solar cars recharge their batteries using solar panels mounted on the vehicle, tapping into renewable energy, thereby reducing reliance on fossil fuels.
3. Zero Tailpipe Emissions: Solar-powered cars produce zero tailpipe emissions since they don't burn gasoline or diesel, which significantly reduces carbon dioxide emissions compared to conventional vehicles.

By utilizing solar power in buildings and cars, we can lessen our dependence on fossil fuels, which are major contributors to carbon dioxide emissions. Embracing solar energy plays a crucial role in reducing greenhouse gas emissions and combatting climate change.
