UPDATE: have a look at Clinton’s house below. Yep, that’s the big plan. Paint your roofs white. From the Atlantic:
I have no problem with saving energy, especially in the summer when power drain is excessive due to A/C load. California now requires most flat-roofed buildings to be white. As a testament to the potential cash savings, Walmart has installed white roofs on 75% of its stores in the United States. Roofs comprise over 20% of urban surface, so while painting them all white in a city, there’s still a lot of asphalt.
But paint roofs white has a downside as well as an upside. It depends on where you live. If you live in a mostly warm climate, say Miami or Phoenix, you’ll realize energy savings. But if you live in Minot,ND or International Falls, MN your white roof will not absorb as much sunlight in winter, thus requiring more energy for heating.
The point is, painting roofs white natiowide, willy nilly, without regard to the local climate, average temperatures, the number of days of sunshine etc. won’t be a full solution.
An idea like Cool Angle, might work, but is far more involved than a paint job.
UPDATE: Reader John provides this image link to the former president’s home. Goose, gander, and all that. We look forward to seeing Bill lead the way.
