Reply to comment by AmberHeardsGrodyTurd in Researchers designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. This cooler may lead to an annual energy saving of up to 86.3 MJ/m² or 24 kWh/m² in hot climates by mossadnik

Again, you're completely wrong. According to the EPA,

> "Urban heat islands" occur when cities replace natural land cover with dense concentrations of pavement, buildings, and other surfaces that absorb and retain heat.

> Trees, green roofs, and　vegetation can help reduce urban heat island effects by shading building surfaces, deflecting radiation from the sun, and releasing moisture into the atmosphere.

Reflecting radiation improves the urban heat island effect, rather than making it worse.

Absorption of heat is what makes it worse, aka what we are doing right now.
