energy

energy is

needed to produce

electricity for homes

and workplaces, and for

communication. electricity

is created by burning fuels such

as coal and oil and by operating hydro-,

wind-, or solar-power stations. Pylons then

carry electricity to where it is required.

food technology

every aspect of food and

its production has been

affected by technology, from

growing and harvesting to

preserving and distribution.

there is now a larger variety
