Towards the energy systems of the future
Infographic showing the old centralised, one-directional energy system giving way to the new people-centered, smart, distributed and multi-directional renewable energy systems of the future. Illustration from the LDC REEEI Framework document.
- Historically, electricity demand was supplied by large, central power generators with a high-voltage backbone and an ever finer grid.
- In the future, because of cost-competitiveness of distributed renewables, the system architecture can be based on interconnected and
multi-directional, smart grids and island grids.
- Solar PV (roof and ground-mounted) will be installed literally everywhere. Wind turbines will complement where economically viable. Dispatchable generators (biogas, biomass, diesel, natural gas, hydro, battery storage, etc.) will complement the local island grid.
- Each island grid can in principle run on its own but higher reliability and lower costs are achieved by interconnecting over time.
