Making renewables work through energy storage and grid management #COP21

solar power plantIn order to deliver a low carbon economy, we must move away from our current low efficiency, high carbon energy system. Our new energy system must be much more efficient, and low carbon.

This will mean abandoning the linear system of large scale, centralised energy production from fossil fuels.

The replacement should be a non-linear system where electricity is produced at widely distributed sites, at various scales, using renewable sources of energy.

To meet base load power demand, this system will need to combine fossil fuels with carbon capture and storage (CCS), and other sources of energy – such as nuclear.

This future low carbon energy system can only work if the way we generate and consume energy becomes much more flexible, and is able to respond rapidly to external weather and price fluctuations.

Matching supply with demand, particularly when a significant proportion of electricity is being generated by intermittent renewable sources, such as wind and solar, will require energy storage.
