Re-duce

For the necessary production and consumption,effort should go into the least energy exploitation.

Used items should be repeatedly exploited to increase their utilization rate.

Re-cycle

Ways should be worked out to recycle used products to promote the energy utilization rate.

Re-newable

Utilize more renewable resources,for example,plant resources,solar energy and wind power.Lessen reliance on non-renewable resources such as oil.
