For every small step we take towards responsible living—buying eco-friendly light bulbs, and so on—there are gadgets that help us make giant leaps in our quest for sustainability. This week in our ...

What happens if you run an electric motor backwards? In short, it stops being a motor and becomes a generator. Following this principle, researchers at the University of Southampton have built a new ...

Tidal power is a fantastic source of clean, predictable energy – if you can harness it. It's proven immensely difficult due to a range of factors, but engineering giant SKF says it's making major ...

Scotrenewables Tidal Power has announced that its 2 MW floating tidal stream turbine prototype has managed to generate more than 3 GWh of renewable electricity during its first year of continuous ...

"During the early hours of this morning … our tidal stream array off the coast of the Pentland Firth became the first tidal stream array in the world to generate 50GWh of electricity," Graham Reid, ...

Tidal power is a way to generate clean, renewable energy by harnessing the rise and fall of ocean tides. Unlike wind and solar power, tidal power is predictable on a regular basis. There are two ...

But there are other types of hydropower that harness marine currents, tidal energy and wave energy, also referred to as marine current energy. Tidal stream turbines work much like submerged windmills, ...

The European Commission has described "ocean energy" as both abundant and renewable. The MeyGen tidal stream array has now exported more than 25.5 gigawatt hours of electricity to the grid since 2017.

Backers of tidal power technology say 2015 is going to be a big year on the road to commercialization. Utility-scale projects in France, the United Kingdom and Canada all show promise, with turbine ...
