The pie charts below show electricity generation by source in New Zealand and Germany in 1980 and 2010. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The charts compare the sources of

electricity

in New

Zealand

and

Germany

in the years 1980 and 2010. Between these years,

electricity

generation almost doubled, rising from 127

units

to 200 in New

Zealand

, and from 107 to 214

units

in

Germany

. In 1980 New

Zealand

used coal as the main

electricity

source

(56) and the remainder was produced from had become the fuel for more than 75% of

electricity

produced and only hydro continued to be another significant

source

supplying approximately 20%.

In contrast

,

Germany

used coal as a

source

of only 28

units

of

electricity

in 1980, which was matched by natural gas. The remaining 49

units

were produced largely from petroleum and nuclear power, with hydro contributing only 7

units

. But by 2010 nuclear power, which was not used at all in New

Zealand

, had developed into the main

source

, producing almost 75% of

electricity

, at 155

units

,

while

coal and petroleum together produced only 55

units

. Other sources were no longer significant.

Overall

, it is clear by 2010 these two countries relied on different principal fuel sources: New

Zealand

relied on coal and

Germany

on nuclear power.
