3. ENERGY
But machines and technologies introduced
during the Industrial Revolution of the late
18
th
century required the use of other energy
resources, especially fossil fuels.

18. Three R’s
The slogan reduce, reuse, recycle is widely
used to raise awareness against the use of
non-renewable source of energy.
•Reduce consumption.
•Reuse manufactured products.
•Recycle raw materials.
