Metal trees with micro wind turbines and plastic solar leaves generate green electricity that can be used right then and there, even in ordinary gardens. They’re not an eyesore, and are more compact and easier to install than their regular turbines.

00:00 It looks like a plastic tree, but this tree is good for the environment.
00:05 Weather conditions here in Artaz, which is home to this animal shelter,
00:10 are ideal for an innovative environmental experiment.
00:13 Close to the Alps it's always windy, making it a great location for wind turbines in the guise of trees.
00:20 For us, environmental protection and animal protection go hand in hand.
00:27 We decided to invest in a wind tree to generate some green energy
00:32 and to steer us away from our dependency on oil and gas.
00:36 This wind tree is a hybrid model.
00:42 It has 30 small wind turbines attached to the branches, which each generate electricity.
00:48 And its 20 white leaves contain solar cells.
00:53 Depending on the weather, this hybrid model can produce between 4 and 16 thousand kilowatts of electricity per year.
01:01 The wind trees are made in Switzerland.
01:04 They are between 5 and 10 meters tall and are particularly well suited to urban areas.
01:09 Big wind turbines need to be quite far away from cities.
01:13 We never see them in cities.
01:15 They have to be placed on the outskirts and they require engineers.
01:19 Our product is close to the consumer and doesn't require any major engineering work.
01:24 The energy that's produced can be used right then and there.
01:28 One tree can potentially supply a four-person household.
01:34 So perhaps one day every garden could have one.
