Singapore using less electricity and water

Home electricity consumption per capita fell from 115.7kWh in 2006 to 108.7kWh  in 2015. This could be due to more people using more energy efficient household appliances such as air-conditioners and refrigerators.

The Paris climate pact seeks to limit global warming to under 2 deg C above pre-industrial levels, and countries, including Singapore, have committed to implementing measures to reduce greenhouse gas emissions. Singapore's climate policy is based on three pillars - fuel switching, increasing energy efficiency, and developing renewable energy. Most of Singapore's electricity is already generated by natural gas, the cleanest form of fossil fuel. But there are limitations, such as the lack of suitable sites, to tapping renewable energy sources.

Increase in Dengue Cases in Singapore

A total of 7,370 dengue cases have been reported in Singapore since the start of the year 2016. Four people have died of the disease so far – a 47-year-old man who lived in Marsiling Rise, a 67-year-old man who lived in Toa Payoh, a 63-year-old woman who lived in Bedok and a 73-year-old woman who lived in Hougang.

The Ministry of Health and NEA have warned that the number of dengue cases in Singapore may exceed 30,000 this year, higher than the record of 22,170 reported in 2013. One of the main factors is the rising temperatures which caused faster breeding and maturation cycles of the Aedes mosquito population.
