Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
Cities all over the world are facing growing challenges to provide clean, reliable water. And many of the fixes, such as desalination plants, have a huge carbon footprint.
The European Investment Bank's funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.
Many Puerto Ricans are happy to see their broke power utility sold off to whoever can get the lights turned back on. But privatizing the island's energy grid may bring more problems than relief.
