Earthquake struck New Zealand

A 7.8-magnitude earthquake and a series of powerful aftershocks left thousands stranded in a New Zealand town near the quake's epicenter. A local state of emergency has been declared for the region of Canterbury, which is home to the areas hardest hit by the quake. Helicopters are being sent to airlift trapped tourists and locals from cut-off communities in the Hurunui and Kaikoura districts.
There have been between 80,000 to 100,000 landslides since the main quake with areas of the Inland and Seaward Kaikoura Ranges the most affected. As a results, a  number of roads are closed indefinitely.

Watch the video below showing how the earthquake uplifted the coastline of New Zealand as well as the other impacts of the earthquake.

The earthquake lifted the seabed by 2m and created new land

New Zealand is located at the plate boundary between the Australian plate and the Pacific plate. Reflect on how this will result in earthquakes.

Singapore using less electricity and water

Individual Effort
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.

International Effort
The Paris climate pact seeks to limit global warming to under 2°C above pre-industrial levels, and countries, including Singapore, have committed to implementing measures to reduce greenhouse gas emissions. 

National Effort
Singapore's climate policy is based on three pillars - fuel switching (Green Plan), increasing energy efficiency (E.g. energy efficient buildings under the Green Mark Scheme), 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. 


Why is there a need to conserve energy and water resources?
