The objective of this report is to find the alternative energies for Singapore electricity sector instead of using fossil fuel such as coal, natural gas and oil by current generating electricity plants. Most of the electricity in Singapore is generated from fossil fuel including natural gas contributed 80% of the total energy demand. The current electricity generating technologies in Singapore are gas-fired combined cycle power plant, combined cycle co-generation plant and oil-fired steam plant.Despite being a small island, Singapore still can harness renewable energies such as biomass, solar, wind and nuclear power. Electricity from renewable resources generally does not much contribute to climate change or local air pollution since no fuel is combusted in these processes.Being able to harness local wind resources and alternative sources of energy will reduce Singapore’s demand and dependence on fossil fuels. Design of turbines is a key issue harnessing wind power. Many of the turbines studied for use in Singapore are based on horizontal axis turbines that will spin when air currents flow in a certain direction and at a certain speed. For a wind energy to be harvested in a tropical climate like Singapore, localised turbine design is necessary. In an urban environment, the strength of vertical turbine is its can accept wind from any direction and operate in low wind speed. In this report, testbed vertical axis micro wind turbine connected to national grid will be proposed which can generate 1kW and unlike horizontal axis turbine; they can be installed side-by-side, taking up a smaller area of space from hilltops to rooftops that produce higher capacity of energy generation. The efficiency of the proposed micro wind turbine can be expected 20 to 30% higher efficiency than other vertical axis wind turbines.
