"We can generate vast power from thin air - the wind. One of the world's biggest wind farms is being built off the English coast where the harsh conditions pose great challenges for the team. Meanwhile, a Norwegian team is striving to build the first-ever floating wind farm."

"The way we fly around the world is about to change. A new breed of aviators who are not afraid to think outside the box, are trying to develop clean, green electric aircraft, and even autonomous sky taxis, with the aim of possibly ending the days of the environment damaging jet aircraft."

"It is the greatest technological challenge ever undertaken by humankind. Fusion - the aim to produce the ultimate unlimited environmentally friendly energy solution. The challenges, at times, seem overwhelming, and it has been dubbed 'bottling a star'. So far the goal of producing a working fusion reactor has remained elusive and out of reach, but we may now be almost there."

"Tidal\n\nThe power of the ocean\u2019s tides is the last great untapped energy source on Earth. From sub-sea kites to floating platforms, teams of engineers are racing to perfect the technology to harness the vast flows of water."

"If global shipping were a country it would be the sixth largest producer of greenhouse gas emissions. But shipping companies and engineers are creating remarkable new machines to make their industry greener, using a resource that has moved man across the world\u2019s oceans for thousands of years\u2026Wind."

"The sun is the biggest source of energy in the solar system. Innovators are searching for new ways to capture more of the sun\u2019s power, and make it available through the night, everywhere."
