The first computer study to simulate the impact of white roofs on cities suggests that they can help cool cities and cut air-conditioning use. The study found that painting roofs white could lead to a 33% reduction in what's called the urban heat island effect, meaning higher temperatures caused by tar roofs and other artificial surfaces. The approach may cool cities by an average of 0.7 degree ...

Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs. Using zinc oxide nanostructures grown.
