The island of Ta'u in American Samoa is home to around 600 people. Located in the southern Pacific Ocean, the island relied until recently on diesel generators for energy production — which meant that not only did the generators produce pollution as a byproduct, but the diesel itself had to be shipped in at a rate of around 300 gallons per day. SolarCity, a company just acquired by Tesla, took a year to set up the island with a bank of solar panels and Tesla Powerpack industrial-grade battery energy storage that means Ta'u now runs almost entirely off the sun.

Scientists at The Australian National University (ANU) have set a world record for efficiency for a solar thermal dish generating steam that could be used for power stations.

The team designed and built a new receiver for the solar concentrator dish at ANU, halving losses and achieving a 97 per cent conversion of sunlight into steam. The breakthrough could lead to the generation of cheaper base-load electricity from renewable energy and help lower carbon emissions which cause global warming.
