The bar chart represents the amount of capital the UK invested in clean energy production between 2008 and 2015.
To begin with, the sum of money invested in energy-efficient technologies, although minimal, has gradually increased. It started at less than 1 billion pounds in 2008 and increased to almost 1 billion pounds in 2015. Furthermore, investments in other sectors underwent slight fluctuations, as it decreased in 2009 before reaching its highest in 2011, reaching roughly 2.5 billion pounds. It remained stable before continuing to decline to around 1 billion pounds.
Moreover, the amount of funds spent on wind energy had an overall increase, even though it significantly decreased because more funds were allocated toward solar energy in 2011. It experienced a considerable jump in 2009, reaching 6 billion pounds before it was cut to 2 billion pounds in 2011. However, it started to rise until it reached almost 10 billion pounds in 2015, whereas solar energy development started below 1 billion pounds but rose to around 3 billion pounds in 2015.
In conclusion, every sector except energy-efficient technologies experienced an increase, with the largest increase in investment seen in the wind energy sector.
