See why this requires global cooperation. finding new sources of more sustainable power was rightly high on the agenda, with 118 governments pledging to triple the world''s renewable energy capacity by 2030. The initiative, led by

Renewable Energy

Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Non-renewable energy, in contrast, comes from finite sources, such as coal, natural gas, and oil.

Can renewable energy sources power the world?

Can renewable energy sources power the world?.The course is made up of eight weeks, with

Nuclear power can play a big role in the energy transition

Nuclear energy - a zero-carbon source - provides 10% of the world''s electricity. As the world transitions to clean energy, nuclear can offset the intermittency inherent in wind and solar energy - but innovation is needed. A new kind of reactor, developed at CERN, could help to overcome the main barriers associated with nuclear power.

We Need a Renewable Energy Transition | Choosing Clean Energy
