Just Friday, Hyundai announced the launch of its first car with a solar roof charging system, which would be first introduced to the newest Sonata Hybrid. Promising to roll out the technology to other cars in the future, the company’s move is its first of many.

Fundamentally, introducing the solar roof should help improve fuel efficiency, boost electric power, and reduce carbon-dioxide emissions. According to the company’s announcement, its silicon panels would allow for between 30 and 60 percent of the car’s battery to be charged through solar.

The impact? Apparently, six hours of daily charging could add over extra 800 miles to the car’s travel distance. To the consumer, that means convenience and saving a whole lot on gasoline.

For now, Hyundai is looking to have its solar roof play a supporting role in powering its cars. Its long term goal is to make powering cars with fossil fuels an obsolete concept, the company alludes. Its new Sonata Hybrid is a small step in the right direction.

Because the Sonata Hybrid does still run partially on gasoline, it does still emit the same greenhouse gases as conventional passenger vehicles. However, it is (and will be) far more fuel-efficient. On average, hybrid cars emit greenhouse gases in a quantity of over 30% less compared to their gasoline-run counterparts.

But the debate over whether electricity is actually cleaner than gasoline still remains. Currently, over 45% of the electricity generated in the United States comes from coal-powered plants. Hyundai is going in the right direction, but still, there are many challenges ahead.
