A Welsh Energiewende

… can Wales lead an energy revolution?

Alan Simpson

Technology is transforming the politics of energy

Tomorrow’s towns and cities …

will become the centrepiece of local power ‘systems’

• …just like 190 German localities already doing

(including >70 local authorities and 9 community-

• wned grids).

Working to different market assumptions -

• Consume less
• Produce and distribute locally
• Invest in energy efficiency and storage
• prioritise renewables, and
• own or manage their local energy Grid.

Local power: the ‘off grid’ village

Electricity: >30% less than retail prices Bio gas produced from animal wastes Community-owned energy co-op

Hamburg: ‘Community Power’

as much about ethics as energy

• local ‘Grid’ ownership and supply
• less before more
• more about ‘systems’ than technologies

tomorrow’s energy security;

a new politics of inter-dependency

• clean before dirty

Ownership of Germany’s 83GW of renewable electricity

• passive house ‘plus’ … PV modules in balcony balustrades … solar thermal roof

units … climbing plants/solar shade … PCM curtains and thermal store … heat pumps.

Hamburg: The ‘Smart is Green’ building

Munich’s ‘solar’ district heating:

• the Ackermannbogen estate

26,600sq/m of solar thermal roof panels feeding a 5,700cu.m reservoir supplying 50% of the estate’s heating needs Backed up by heat pump and district heating connections

Sonnenschiff - Freiberg’s ‘solar city’

…producing 4x the amount of energy it uses.

Changing the way we think

Installing solar … on everything that doesn’t move

Being creative: …joining up the dots

…the power

• f ‘poo’

Storing and sharing

Last year, Germany installed 15,000 local energy storage systems … and dozens of other manufacturers are in hot pursuit. Tesla has launched its ‘Powerwall’ system across the US and Europe

Back to the Future?

Manchester, 1817: socially owned, local energy

1947: 50% of LA income came from their

• wn utilities

2017: local energy networks smart grids storing, saving and sharing

… changing everything.

Robin Hood Energy

…fighting for the right of ‘local supply’

• local generation
• clean energy
• store & share
• energy saving
• local tariffs

Dancing differently:

… a tango, not a rave

• partnerships
• sharing the gains
• proactive planning
• mutual security
• leading or owning?
• an ‘accountable’ energy

system.
