Comment and analysis from our editorial staff and professionals in the field.

Green energy in the EU

The European Union aims to get 27% of its electricity from renewables by 2030. Some member states have already gone well past that (e.g. Sweden at 52%) , but others lag behind (e.g the UK at 5%), with changes in support schemes adding to the uncertainty.

Renewables in the USA

Renewables supply nearly 15% of US electricity at present, and seem certain to expand, despite the political stalemate: up to almost 50% of power by 2030 is seen as possible, and 27% of total energy - the same as the EU's target.

Green energy in Africa

Africa has a very large renewable energy potential that is only now being developed, with the UN Sustainable Energy for All programme, along with many others, providing some help to local initiatives.
