The city of Sidney created a plan to reduce their greenhouse gas emissions by70% until 2030 and their plans are to be 100% independent in energy and water.
A key component of Sustainable Sydney 2030 is the call for a Green Infrastructure Plan which comprises:
Decentralized Energy – Trigeneration Master Plan (cooling, heating and power network in the City)
Decentralized Energy – Renewable Energy Master Plan (renewable energy sources: solar panels, wind and/or waste)
Advanced Waste Treatment Master Plan
Decentralized Water Master Plan
When a city create scale (master plans) makes the difference
Environmental upgrade agreement is a program that helps the residents to get their money back from investing in green technologies.
Waste to energy – food waste, wood, agriculture waste (livestock) = renewable gas
Natural gas more expensive than renewable gas
Building technologies (solar photo voltaic mainly)
Precinct scale technologies
Natural gas transportation is 20% cheaper than energy
To show the residents and business how much greenhouse gases their building generates the City of Sydney created a graphic. The graphic below shows the projection in 2030 without decentralize energy network and showing with a trigeneration.
Power generation. Renewable energy provides 19% of electricity generation worldwide.
Renewable power generators are spread across many countries, and wind power alone already provides a significant share of electricity in some areas: for example, 14% in the U.S. state of Iowa, 40% in the northern German state of Schleswig-Holstein, and 49% in Denmark. Some countries get most of their power from renewables, including Iceland (100%), Norway (98%), Brazil (86%), Austria (62%), New Zealand (65%), and Sweden (54%). (source: Wikipedia)
