For example, energy conservation is a form of memory (an elastic band remembers how much energy was put into stretching it and eventually goes back to the original position).
Energy conservation could as well have been accomplished by resting quiescent without shutting off the organism from the environment, potentially a dangerous situation.
Flow-through shares allow investors to make tax-advantaged investments in companies involved in sectors such as mining, oil and gas, renewable energy and energy conservation.
Energy conservation, difficult as it is in a cold wave, may require such measures as collecting people (especially the poor and elderly) in communal shelters.
