The given pie charts reveals the generation of electricity in New Zealand and Germany for the years 1980 and 2010 consecutively. There is a significant increase in the electricity production in both the nations over the period. Further, Germany depicts increased production than New Zealand.
In one hand, if the resources for electrical power generation are compared for the two nations, it can be seen that for the year 1980 the sources were appropriately distributed and produced nearly equally.
Similar power units However in the year 2010, the major unit generation was the grey source, covering almost 75 percent of the total production. In addition, a glance at the chart of Germany depicts that the yellow source of production apparently grain fans approximate 12 percent in 1980 and also 15 percent in 2010. The green and the blue sources have altogether diminished to an eye-catching amount. Furthermore, comparing both the countries, in year 1980, both countries relied on all the sources of production, but eventually over the years, a single resource has taken a great portion of the production chart. Overall, there is a positive increase in production of total electrical units for both the countries.
