/ Many targets have been set, and many predictions made, but what really needs to be done for the world to transition to an entirely renewable energy system? We take a look at the technologies that will pave the way for a cleaner energy future.

As the UK increasingly embraces renewables, it is moving away from coal for good. We profile the seven remaining coal plants in the country.

Solar panels are one of the most popular and successful forms of renewables, yet they remain hugely inefficient. How can you balance increases in efficiency with cost?

Hydropower has come under criticism following a report produced by the World Bank showing that the technology can hold back nations. Should countries steer clear of the power source? New, alternative technologies and solutions are constantly being developed, and the Start-Up Energy Transition (SET) initiative has produced a list of the top 100.

Finally, we look at the nuclear renationalisation debate in France, the UK's failing power companies and what can be done about them, and how the energy recruitment sector is powering up. /
