How do you power a tropical island with little land, but over 300 days of sun a year? The solution: putting photovoltaic systems out to sea. Read on

Solar power trade-offs are a classic problem for clean energy solutions — the cheapest solar panels are usually the least efficient, because they don’t use complicated manufacturing processes. Read on

There's another way to generate power from our oceans - and a team at the University of Edinburgh, working with researchers in Italy, have shown encouraging results from initial work. Both wave and tidal energy harvesting remain incredibly important methods for generating renewable energy from sources that don't stop at night or need wind to work. Read on

While the concept of storing thermal energy in molten salt has been around for decades, a new approach - from one of Google's sister companies - combines hot energy with cold to create a temperature difference that can be utilised to generate power. Read on

What if you could farm energy and edibles on the same piece of land? Read on

The solar sector itself is not without environmental impact - especially in relation to rare-earth minerals. However, could humble old iron be about to change that? Read on

An Australian invention that uses wave power to safely generate renewable energy is on its way to its first large-scale test. Read on

Swedish researchers have developed a new breed of molecule which could make storing solar energy all the more efficient. Read on

The winner of the 2018 James Dyson Award is an innovative new wind turbine designed to harness wind power even in the inner city. Read on
