Forget all you have heard about how “Renewable Energy” is our salvation. It is all a myth that is very lucrative for some. Feel-good stuff like electric cars, etc. Such vehicles are actually powered by coal, natural gas… or dead salmon in the Northwest.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

Offshore wind farms are a major player in the move away from fossil fuels, especially in the North Sea, and they are increasing in number. But their impact on the environment is not yet clear: We take a look at ongoing research in Europe that is measuring the impact of wind turbines and their harm, or benefit, to biodiversity in our seas.

A documentary short that uses fish to explore identity and belonging in a metropolis.

An overlooked engineer is sent to Alaska to scope out an eccentric scientist's claim that capturing lightning can be a new source of renewable energy.

Nuclear energy: a clean energy for the future or a risk for humanity? As the European Union has classed nuclear as a green energy, France is building new power plants whilst Germany is decommissioning them. An in depth look at the future of atomic energy in the coming decades.

A portrait of free diver Kathryn Nevatt, former World Champion and current New Zealand record holder in all three disciplines.

When an alien visitor discovers it can communicate with Earth’s oceans, it becomes the only intermediary between humanity and a vast marine intelligence whose patience with the human race is running out. Part survey, part discovery, the film explores a stretch of the wilderness that has largely slipped through the cracks of human attention, and in some places, bears the marks of human failure. The alien encounters a force both beautiful and terrifying, a voice as old as the planet itself, carrying memories, warnings and a power beyond human control. The film is a parable about nature on Earth by establishing an unidentified alien as interacting with the planet. By way of subtle messages the sea warns the alien that the existence of the planet is at stake. The alien discovers a controlling city but does not interfere with it and hopes that the sea will find a way to survive.

An homage to the weird and wonderful world of B-movies, this short fauxdocumentary by film artist Chris Gerrard splices together classic clips with some new footage to tell the ludicrously fake story of the mysterious people (and things) lurking beneath us in the eerie River Tay. Feast your eyes on this unique archaeology of aquatic-themed film.

A three year self-described labour of love, 2040 takes the form of a visual letter from the filmmaker to his four-year-old daughter Velvet, showing her what the year 2040 could look like “if we simply embraced the best solutions that exist today.”

«Energy Pioneers» portrays two visionaries and their fellow campaigners as they fight to solving one of humanity’s most challenging problems. A film about obstacles, crises and the power of an idea.

Sixty years ago, the Canary Islands were the first in Europe to adopt desalination of ocean water to produce drinking water. Often considered a miracle solution, is this technique compatible with sustainable development?

The Balkans cradles Europe's last wild rivers and supports abundant wildlife and healthy, intact ecosystems. These rivers are "The Undamaged" – clean, pristine, and undammed. With over 2,700 small and large hydro power plants planned or under construction in the Balkans, corruption and greed are destroying the last free-flowing rivers of Europe. Follow the Balkan Rivers Tour, a rowdy crew of whitewater kayakers, filmers, photographers and friends who decided to stand up for the rivers, travelling from Slovenia to Albania for 36 days, kayaking 23 rivers in 6 countries to protest the dams and show the world the secret wild rivers of the Balkans. The film honours everyday people and local activists who are fighting to defend rivers and aims to spread the word of the plight of these rivers, showing a new style of nature conservation that is fun, energetic and effective.

Yaku: water; aya: essence, blood. Yakuaya is a non-verbal documentary about the descent of water and life that follows the journey of a drop of water from its birth on a glacier until its arrival at the sea. Along the way, water influences the life of a peasant, locks himself in the rhythm of a bottling factory, brings people together in the city, transforms the life of a woman, leads a river navigator, awakens hope in a desert and welcomes the innocence of two children in the sea.

When the Tanana River bridge was installed in Salcha, Alaska, the community worried about the levee's effects on fish wildlife. Salcha Elementary School, along with the help of Tanana Valley Watershed Association, conducted a 10-year scientific project with students to study the effects the levee had on Piledriver Slough. Tori Brannan - the filmmaker's mother - is a retired principal at Salcha Elementary and was the project's centerpiece. She shares her experiences with the project, the community, and how her daughter's involvement strengthened their relationship.
