Streetlights that only Light up when Needed | White Spaces
Tvilight, based in The Netherlands is working to better an ongoing issue within Europe; their power expenditure. Research has shown that Europe spends 13 billion per annum powering street lights, which translates to 40 percent of their total energy costs. Tvilight has made it their purpose to cut this cost by 80 percent with the product CitySense.

This High Concentration Photovoltaic Thermal System (HCPVT) can harness the energy of 2,000 suns and provide fresh water and air conditioning in remote locations. The prototype HCPVT system under development uses a large parabolic dish, made from a multitude of mirror facets, which is attached to a tracking system that determines the best angle based on the position of the sun. Once aligned, the sun’s rays reflect off the mirror onto several microchannel-liquid cooled receivers with triple junction photovoltaic chips — each 1x1 centimeter chip can convert 200-250 watts, on average, over a typical eight hour day in a sunny region.

Namaste Tower: A Welcoming Gesture Of Green Design | Earth Techling
Looking more like a giant sculpture than a working skyscraper, the Namaste Tower currently under construction in Mumbai, India, is expected to be as green as it is beautiful to behold. The building will also incorporate a renewable energy system to help produce hot water, abundant greenery in the common areas and several passive systems to help reduce energy demands.
