Among 'green' energy, hydropower is the most dangerous

Many governments are promoting a move away from fossil fuels towards renewable energy sources. However, in a study published today, scientists highlight some of the ecological dangers this wave of 'green' energy poses.

A new material for the battery of the future

Renewable sources of energy such as wind or photovoltaic are intermittent; production peaks do not necessarily follow the demand peaks. Storing green energy is therefore essential to moving away from fossil fuels. The energy ...

Nanostructures improve solar cell efficiency

To make solar cells a competitive alternative to other renewable energy sources, researchers are investigating different alternatives. A step in the right direction is through new processes that change the surfaces of silicon ...
