Wind turbines are often denounced as being notoriously bad-looking, so French company NewWind has been working on a solution. Their new device, Tree Vent, is a set of vertical wind turbines designed to mimic the look of a tree. The ‘trees’ are 11 metres tall and eight metres in diameter at their widest point, and can hold 72 vertical turbines. With a power output of 3.1 kilowatts, several ‘trees’ can be used together in a garden, park, or along the side of a road to generate enough energy to supplement the energy use of the homes and buildings nearby.

Smart waste-management could improve the efﬁciency of recycling systems and combat excess pollution. Collection trucks usually take the same routes each week regardless of the amount of waste to be collected. It’s possible this system is no longer the most efﬁcient option and can mitigate the beneﬁts of recycling by adding to the emission of pollution. Smart waste-management systems monitor the fullness of waste containers and send real-time updates when a collection is required. aEnergis, a company specialising in wireless data transmission for communities, says their system helps communities optimise their waste collection rounds to save fuel, equipment use, time and the environment.
Santa Monica may become the ﬁrst city in California – and one of the ﬁrst cities worldwide – to require new single-family properties to meet net-zero energy standards. This means new projects within the city must be able to generate enough energy from renewable sources that they subsidise the amount used from a power utility within 12 months. Downtown Santa Monica is one of the leading cities in America when it comes to efﬁciency and sustainability, and California has a statewide energy goal to see all new residential construction be net-zero by 2020.
