Singapore has set up an energy-efficient green space called Gardens by the Bay that has cost 1bn Singaporean dollars ($784m; £504m).  The man-made ‘supertrees’ mimic the qualities of trees here on earth.  Seven of the 18 structures are fitted with solar panels that convert sunlight into energy.

Clean technology is a growing commercial sector for Singapore.  Some 80% of Singapore’s power generation comes from natural gas, the cleanest of the fossil fuels, according to the Energy Market Authority. Some of its oil refineries and petrochemical companies which account for 50% of all carbon emissions have also made the switch to natural gas. (BBC, 18th June 2012)

Tata Steel is tackling the challenges of developing a more sustainable approach to its business by building ethical and sustainable practices into all areas of its operations. Using new technology Tata Steel is re-using gases from its steel operations to create electricity.  This has reduced its reliance on natural gas for power and also reduced its CO2 emissions.

Singapore is also committed to reducing its carbon emissions. Authorities are promising a 7-11% cut by 2020.  The goals seem particularly ambitious given that Singapore says a total abandonment of fossil fuels is very difficult for the country because it is ‘alternative energy disadvantaged’.

Hydroelectric, geothermal, wind, tidal and even solar are not viable renewable energy sources for Singapore because its geographical region and size mean it cannot adopt these types of renewables on a large scale.
