This passage provides information on the subsidising of renewable energy and its effect on the usage of fossil fuels. The issue of subsidising sources of renewable energy came to the forefront of global politics as record emissions levels continue to be reached despite caps on carbon emissions being agreed up by several global powers.However, renewable energy sources tend more expensive than their fossil-fuel counter parts. In this way, renewable energy cannot be seen as a realistic alternative to fossil-fuel until it is at a price universally achievable. On the opposite side of the spectrum, commentators note that the average temperature is expected to rise by four degrees by the end of the decade.In order to prevent this, they suggest carbon emissions must be reduced by seventy per cent by 2050. Such commentators advocate government subsidised renewable energy forms as a way to achieve this target.
