Ni–Cd batteries contain between 6% (for industrial batteries) and 18% (for commercial batteries) , which is a and therefore requires special care during battery disposal. In the , the expected cost (to be used for proper disposal at the end of the service lifetime) is rolled into the battery purchase price. Under the so-called "batteries directive" (), the sale of consumer Ni–Cd batteries ha.

Any must match electricity production to consumption, both of which vary significantly over time. Energy derived from and varies with the weather on time scales ranging from less than a second to weeks or longer. is less flexible than , meaning it cannot easily match the variations in demand. Thus, without storage presents special challenges to .
