The end of the world as we know it

The Earth seen from Apollo 17

Where are we at? In the 21st century the world has entered a time of great change. Following the industrial revolution, humans learned how to extract and use fossil fuels in great quantities. This led to an era of cheap and apparently abundant energy for keeping warm, artificial light, transport and creating electricity. First world… Continue reading The end of the world as we know it

Biofuels

Biofuels are derived from biological sources such as plants and algae. With dwindling fossil fuel supplies, many types of biofuels such as ethanol and vegetable oils are now being used for transport, industrial and domestic purposes. “Good biofuels” are produced from waste organic matter that is not produced from environmentally destructive activities. For example, using crop waste… Continue reading Biofuels

Heat pump

MSZ-FB25VA heat pump inside

A heat pump is a machine or device that moves heat from one location (the ‘source’) to another location (the ‘sink’ or ‘heat sink’) using mechanical work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink.[1] Common examples are food refrigerators and freezers, air conditioners, and reversible-cycle heat… Continue reading Heat pump
