Renewable energy is better for the environment than fossil fuel alternatives, but is it always best for business? One German startup hopes to make it a more robust option, with the help of an innovative and reliable renewable energy storage solution. Read on

A new clean energy harvesting solution could help optimise ocean observation technologies - making them more resilient, powerful, eco-friendly and a whole lot more effective at collecting valuable data. Read on

A technology called AuREUS , which uses waste materials to turn UV light into electricity, even without direct sunlight, has won the James Dyson Award’s first-ever Sustainability Prize. Read on

The heat that reaches the Earth from space has long been used to generate electricity, but can the concept work in reverse? Read on

Cheaper and thinner solar power cells could lead to more affordable and more accessible renewable energy - for more people. But does it also bring new challenges? Read on

In theory, a world powered entirely by renewables is possible. But given the natural fluctuations of the wind, waves and sun, how can we ensure that the green energy market of the future is safe, fair and truly sustainable? An open source project Power TAC is using machine learning simulations to help us find out.

Swapping out glass panels for transparent solar modules, and harnessing the energy from wavelengths of light not used during photosynthesis, could help turn greenhouses into self-sufficient solar power plants. Read on

A emissions-tracking tool, developed in Britain, is using machine learning to work out if the next 96 hours of electricity has been sustainably produced - offering a big boost to both energy-consumer transparency and the transition to renewables. Read on

Like every person, every building is unique. So how can you easily, affordably and reliably reduce the energy consumption of something so complex? An American start up delivers a digital solution. Read on
