Nobel Prize in Physics advocates that roofs around the world should be painted white to stop global warming

Of the current United States Secretary of Energy in the 'Filling whiten in the city, it is at the very least, if impossible to whiten around the world of the house,' said Nobel Prize in Physics laureate Steven Chu Mr. (Steven Chu) has been proposed.

It may seem logical to consider the coolness of traditional white houses on the Mediterranean coast and the amount of heat stored on black asphalt roads, but by turning roads and roofs around the world into whitish colors, It seems that the same effect can be obtained as if all cars disappeared from the earth for 11 years. It seems ridiculous to hear that 'the world is filled with white', but it may be an unexpected shortcut as a measure to prevent global warming.

Details are as below. US Energy Secretary says painting roofs white will save energy

The Obama administration intends to repaint the roof of buildings with white, which has high energy reflectance, as a measure against global warming, Chu announced on May 26.

“A “new revolution” in power generation is essential to significantly reduce greenhouse gas emissions,” says Chu. However, there are no policies that can be a silver bullet, and he says that various measures should be taken, including painting the roof white.

By changing the roads and roofs to a whitish color, the same effect as cars disappearing from the earth for 11 years can be obtained. 'It's completely harmless, it's a geotechnical plan that keeps buildings cool, reduces energy consumption from air conditioning, and also bounces sunlight back from the earth.'

Also, making the car a brighter color has the effect of significantly reducing the energy used by the air conditioner.

Chu says new thinking is needed to reduce the amount of carbon gas generated by power generation. “The Industrial Revolution was a revolution in the way we use energy. We used fossil fuel energy to do what we used to do with human and animal power. We significantly reduce carbon emissions during power generation. It's time to create a new 'revolution' that can be reduced.'

It may be difficult to change the roof to white, but when you buy a new car, you may want to start with what you can do, such as choosing a car body or interior with a color that does not easily store heat.
