The new Google headquarters in California is achieving its goal of working with green energy 90% of the time by powering its building with solar panels inspired by 'dragon skin'.

The 2 sun drenched office buildings take up 1.1 million square feet covered by 90,000 silver solar panels. The result is a set of builidings that show what's possible in human-centered and sustainable workplaces.

The prismatic nature of the glass traps the light that would normally escape from traditional flat solar panels and reduces reflective glare that can be a problem for drivers and pilots.

To help deliver on its commitment to  replenish 120% of the water it consumes by 2030, the site is net water-positive with all non-potable water demands being met using the recycled water it generates on site.

A series of above ground ponds gather rainwater, combined with a building wastewater treatment system, together to serve as a water source for cooling towers, flushing toilets and landscape irrigation.

A massive group of 12,000 solar panels are set to become Europe's largest floating solar park when they finish taking position on top of the Alqueva reservoir this year.

Supplying a third of the  eletricity to the nearby towns of Moura and Portel - they look to continue taking advantage of Portugal's nice year-round weather that has seen the nation become one fo the leading renewable-powered nations in Europe.

The advantage of floating solar is that it doesn't take up limited land space in the small country. Unused electricity that can't be used pumps water into the reservoir, which can be fed through the hydropower system of the dam to create additional power.

By 2030 Portugals principal utility provider (EDP) hopes to offer 100% renewable electricity across all infrastructre, while currently producing 78% of its power from solar, wind, and hydropower.
