Government figures have revealed that 15 per cent of domestic gas and electricity prices are made up of taxes to help fund green policies.
The Daily Mail reports these levies go into schemes to cut the country's carbon emissions and pay for renewable energy developments such as wind farms, while also helping to upgrade the UK's power infrastructure to deliver energy made from these sources.
It added that unless measures are taken to make homes more efficient, the average domestic energy bill could increase by around £200 by 2020 as a result of these expenses.
By then, under the highest price scenario, gas could cost as much a £997 a year, while annual electricity cost may reach £812.
Recently, government figures obtained by the Guardian suggested two-thirds of households will see their bills rise by 2020, despite efforts to reduce energy usage.
