Stockholm the Royal Seaport project Urban Development - Full scale test of solutions for Sustainable Cities

Sao Paulo and Stockholm to lead C40 Cities Climate Leadership development program

Renewable electricity certificate - A co-operation between Sweden and Norway

Key figures • 12,000 new residences and 35,000 new workspaces • By 2030, the city district should become free of fossil fuels and adapted to climate

change. • By 2020, CO2 emission less than 1.5 ton per person and year. Reducing the demand by

energy efficiency improvements. • Fully developed by 2025.

Focus areas • Transport: Public transportation, electrical cars and car pools, cyckling • Energy-plus-housing • Waste management: ”Easy-to-do-right” sorting and biogas production Key technologies • Urban Smart Grid, Smart waste collection, Smart ICT, Smart City SRS, Smart

communication

Key Questions

Projected Swedish Source Energy Mix 2050

Total Proportion of Renewable Source Energy (2009)

Can Sweden continue its renewable path?

• Are nuclear and waste-to-energy sustainable? • Is a ~30% reduction in energy demand

feasible? • What is the true energy balance of biofuels? • Can current 35% conversion losses be reduced?

Swedish electricity (2009) is 85% Nuclear and Hydro

Oil accounts for 30% of total primary energy supply, and

biofuels 20%

Wind, Solar, and Efficiency are expected to drive change

Farmarenergi - A non-profit co-operative of 19 farmers in

Kolbäck – 2 000 habitants

History • 1980 – EU legislation => Reduction in wheat production =>

Reuse 1 600 ha of cropland for energy crop growth.

• 1990 – Farmaenergi is founded. Mixed financing from farmers, Kolbäck municipality, the Federation of Swedish Farmers, the region, and bank loans. Decision to invest in biofuel furnace for municipal power plant and 200 ha of Willow Salix energy forest

• 1992 – Biofuel incineration plant in operation

• 2006 – Bankruptcy of Farmaenergi. Outcompeted by a large power company.

Challenges of co-operatives: • Large investments lead to difficulties in securing financing • Establishing relationship between stakeholders • Competition from large power companies

Transportation = Oil

Industry = Biofuels / Electricity

Residential sector = Electricity / District Heat
