Scientists Created the World's Whitest Paint. It Could Eliminate the Need for air Conditioning.

Whitest paint in world created at Purdue, may help curb global warming:
The paint has now made it into the Guinness World Records book as the whitest ever made.
So why did the scientists create such a paint? It turns out that breaking a world record wasn't the goal of the researchers: Curbing global warming was.
[...] Making this paint really reflective, however, also made it really white, according to Purdue University. The paint reflects 98.1% of solar radiation while also emitting infrared heat. Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power.
Using this new paint to cover a roof area of about 1,000 square feet could result in a cooling power of 10 kilowatts. That's more powerful than the air conditioners used by most houses," Ruan said.
[...] Two features make this paint ultra-white: a very high concentration of a chemical compound called barium sulfate - also used in photo paper and cosmetics - and different particle sizes of barium sulfate in the paint, scientists at Purdue said.
Will the reflected sunlight cause more global warming or less ?? And, what happens on cloudy days ?
