Tina interviews Mirja Löhr, the director of the company Ekomo. The start-up has created a heating system that works using induction and can therefore be much more sustainable than heating with oil or gas.

Life in the alpine pastures of Tyrol has its own pace in tune with natural cycles. We visit an alpine farmer and his wife and learn about traditional dairy products and how they are made.

In this segment, we see how the churned butter is put into a traditional wooden mold, take a look at some more farm animals, and catch a glimpse of the "Daberklamm," an alpine gorge.

In this segment, we get to know the bearded vulture, a scavenging bird of prey that has resettled in the Hohe Tauern National Park. Now there are even stations in the park that address some of the misconceptions that almost led to this bird's extinction.

Up in the mountains, a vulture and an eagle fight for their territory while conservationists watch closely. The series ends with a view of the Venediger Group, a famous high mountain range.

In this segment, we explore the beautiful landscape around the Staller Saddle mountain pass, visiting alpine roses, a pack of magnificent stags, and a traditional tavern where local farmers carry out their negotiations.

Our exploration of wildlife in the Tyrolean Alps continues as we visit cuddly marmots and one of their most fearsome predators: the golden eagle.

In a rare close-up, we see the mother eagle working hard to keep its offspring fed. Then we get a look at the Innergschlöß, an 800-year-old Alpine settlement.

In this video, physicist and author Harald Lesch talks about how Germany could phase out coal and nuclear power completely and still meet all of its energy needs.

In this segment, we visit quaint settlements, a chapel carved into a rock, and a waterfall that seems to disappear into the earth, all at the foot of some of the tallest mountains in Europe.

In this segment, we finally glimpse the peak of the Großvenediger. Back down in the valley, families make hay without the usual farm machinery.

Whitewater rafting and kayaking are very popular but also very dangerous sports in the Alps. Here we see some remarkable footage of a few daring individuals making their way through the thundering rapids.

Germany is not a big enough country to devote all of its land to creating renewable energy – but there is another place with vast expanses of empty space and limitless sunshine.

Canyoning is another popular activity in the Alps, but it isn't for the faint of heart. In a glorious natural setting, the group faces some tough passages and harrowing jumps over waterfalls.

As autumn approaches, the sheep are brought back to their winter quarters. In this segment, we also see how beautiful the region is in the evenings.
