Why Local Energy Systems are Essential for a Low Carbon Future Mary@mgillie.co.uk Mary Gillie, Engineering a greener future Thursday, November 29, 2018

What I want to talk about A bit about me The problems to be solved and how local energy contributes. Some examples of the types of solutions Mary Gillie, Engineering a greener future Thursday, November 29, 2018

Me Applied physicist and electrical engineer by training. Worked on R&D and field trials developing smart grids for 10 years. This lead to working with communities on energy projects, demand side management and energy efficiency. Work at different points of the spectrum from communities to international project.

The problems to solve An energy system that Is low carbon end to end. Incorporates intermittent renewable energy Is affordable and manages many sources heat and power Minimises vulnerability to extreme weather and terrorist attack Encourages responsibility by consumers. No ‘Business as Usual’ Mary Gillie, Engineering a greener future Thursday, November 29, 2018

Is low carbon end to end This requires renewable energy. Some sources are large –scale but others are small scale. Small scale renewables need to be managed locally. Biomass requires a local supply chain We need local systems Mary Gillie, Engineering a warmer greener future Thursday, November 29, 2018

Incorporates intermittent renewable energy We can develop storage but matching load to demand is more efficient. We need to use controllable loads but managing domestic demand is complex. Load is more easily managed at a community scale. Local communities can then get the benefit. Mary Gillie, Engineering a warmer greener future Thursday, November 29, 2018

Is affordable and manages many sources heat and power We have a quiver of silver arrows, not one magic bullet. We need to use local sources for local supply. This could be various biomass, wind or solar, depending on location. The jigsaw is easier to complete locally Is affordable and manages many sources heat and power Mary Gillie, Engineering a warmer greener future Thursday, November 29, 2018

Minimises vulnerability to extreme weather and terrorist attack Local generation, means damage in one location doesn’t jeopardise the whole supply. Short supply links reduces vulnerability. Interconnection increases resilience as long as different systems are not reliant. Needs local control. Minimises vulnerability to extreme weather and terrorist attack Mary Gillie, Engineering a warmer greener future Thursday, November 29, 2018

Encourages responsibility by consumers. Local generation and ownership raises awareness. People understand why responsible use is required They can get a benefit from participation. Encourages responsibility by consumers. Mary Gillie, Engineering a warmer greener future Thursday, November 29, 2018
