This idea might seem absurd, but I have always imagined how much power we could obtain if cars' rooftops had solar panels. It makes sense because several vehicles spend several hours under the sun. Positioning solar panels on top of cars would be a clean solution to more energy in an environmentally positive way. Solar energy is renewable and does not release any emissions or harmful products in the process of obtaining it. In addition, I don't think that this innovation would harm the environment that much because no additional processes or emissions would be produced. People could still drive around normally, except their solar panels would be absorbing solar energy simultaneously.  Not only could cars contain rooftop solar panels, but buses, trains, etc. could also absorb energy with panels. Personally, I don't think our society will ever be able to stop driving or emitting greenhouse gasses from transportation. But I think we can take these steps to do some good while we harm the environment.

I completely agree with you. Solar energy has many pros to it, such as being renewable, sustainable, environment-friendly, and does not produce CO2 at all. If cars were powered by solar energy, there would be so much less CO2 in the air and your idea would greatly help in the process of averting Global Warming.

I think this is an awesome idea! Solar panels should be on every car. Something I would take into account is that in order for this to work, solar panels have to have a power to weight ratio that is great enough to propel the car at a fast enough speed and drive for sustained periods. So I did some research. A car engine can weigh almost 600 pounds. But On average, solar panels and the mounting equipment weigh 2-4 lbs per square foot. The car is on average 15 feet long and the overall weight of the solar panels on it turns out to be between 12-28 pounds. Way lighter than the engine! The effectiveness of the solar panels would be increased if the engine compartment was completely scrapped, and the solar panel replaced it. This way the car might be light enough to be effectively powered by the solar panel. But I still don't know the power to weight ratio. I used google as a source and searched for stuff like "How long is the average car" and "how heavy are solar panels".

Solar panels are really good for clean energy. But I find a problem when I'm thinking about it. If solar power becomes really common in the future, such as all cities getting 80% of power from the Sun. What will it be like? I think that there might also be some global problems. It is because the wind is powered by heat from the sun mostly. What will happens if there's no wind or much less wind than today?

I agree. Solar panels on cars would help the environment a lot. we would have cleaner air and a very much safer area to live in. This could reduce our time we have until climate change because there will be less co2 in  the air.

I agree with this a lot! this idea is fantastic. Solar panels on cars would help decrease global warming and would also create our cities and towns much cleaner. Although I do question, how would people drive around at night if the cars are run by sunlight, or if it was extremely foggy out and the sun was nowhere to be found?

I think the idea of having solar panels on cars is an incredible idea, but it can be enhanced a bit more. First of all, solar panels will not work when the weather isn't right. This means that when it's raining, the car will not have any power. In addition, currently, solar panels cannot produce enough power. Even if it does, the car will not be able to reach high speeds due to the power limit, which will be determined also by the weather. Nonetheless, these two problems can be solved by adding large batteries. Similar to the current electric-powered cars, it allows recharging, but as well as solar panels which will provide extra power to the car. This way, the car can be more energy-efficient as well as be able to run at any time at high speeds.
