As the main cause of global warming is greenhouse gases congregating in the earth's atmosphere, the principal strategy has to be to use less energy particularly that derived from fossil fuels and to use what is needed more efficiently.
Kuna globaalse soojenemise peamiseks põhjuseks on kasvuhoonegaaside kuhjumine Maa atmosfääri, on oluline kasutada võimalikult vähe fossiilkütustest pärinevat energiat. Samuti on vaja tõsta energia kasutamise tõhusust.
