Zero-Emission Technologies

Zero-emission technologies do not emit greenhouse gas into the atmosphere. “In the energy sector that means using non-fossil energy sources, i.e. nuclear or renewables. However, neither is entirely carbon-free – at present we use fossil fuel to make the materials for the energy conversion technologies involved and, in the case of nuclear, to extract and process nuclear fuel. Nevertheless, they are both low-carbon options.” (PhysicsWorld, Oct 2018)
