Energy & Environment

Environmental issues, especially climate change, have become hot topics around the world in recent years due to the magnitude and scope of its impacts. Carbon dioxide and greenhouse gases emitted by human activities, particularly related to energy consumption, have shifted weather patterns across the globe, causing extreme weather such as hurricanes, drought, excessive rainfall, and unusual temperatures. In 2015, majority of the world came together and agreed to limit global warming to well below two degrees Celsius, known as the Paris Agreement.

Commercially-produced energy is derived from fossil, nuclear, and renewable sources. Since fossil fuels have been identified as a major source of carbon emissions and cause of climate change, many countries have subsequently started diversifying the focus of primary energy sources from fossil fuels to other sources, particularly to renewable energy.
