The potential for renewable is immense. In urban
centres, many efforts are being made to utilize all potential of the natural
and renewable energy to reduce costs and improve efficiency and quality in
urban environments. Especially in smaller developing cities where there is more
opportunity to test new and innovative technologies.
In the book 'Renewable City', Droege sums up the
tool that could be used given the source of renewable energy available.
- Solar energy - could be captured by
photovoltaics and solar-thermal systems - largely used in commercial,
residential or industrial buildings, or in rural areas as well.
- Wind energy - captured by turbines - for its size
and impacts it could be used in remote areas or remote buildings. However in smaller
scale it can also be used on the top of high rise buildings.
- Bio-energy - biofuels - used in power stations
and for transport systems, causing less impact on the environment.
- Ocean energy - thermal, tidal power or wave
energy - this source of energy can be largely used in coastal regions, however it
is still not fully developed.
