The table below gives details of world electricity production by renewable sources in the four years between 2009 and 2012. Summarize the information by selecting and reporting the main features and making comparisons where relevant. Write at least 150 words.
The table illustrates the percentage of
power
produced from different sources of sustainable
energy
and the number of employees engaged in each of these sectors.
Overall
,it is quite obvious that hydropower generates the highest proportion of electricity,
whereas
solar
energy
only contributes a fraction of
power
compared to other renewable sources. The highest percentage of sustainable
energy
was produced by hydropower, followed by wind
power
in second place,
while
both of them had an average of 1100 workers in 2009.
In contrast
, solar
power
accounted for the lowest percentage of electricity production, with 12450 workers contributing 3.6% of the
energy
.
On the other hand
, tidal
power
and geothermal
energy
contributed around 6.8% of
energy
production but later had 2566 more employees than tidal.
Hence
, it makes it clear that tidal
power
is more efficient than geothermal
energy
.
