Two departments have responsibilities in this area.
The department of energy and climate change (DECC) is responsible for all aspects of UK energy policy, and for tackling global climate change on behalf of the UK.
"To achieve secure, affordable and low-carbon energy in the years and decades ahead, we need an energy mix that is diverse, both in terms of technologies and geographical sources of imported fuels, within a market framework that offers us competitive prices," the department says.
Another key role at DECC is to help the UK move to a low-carbon economy.
The department for environment, food and rural affairs (Defra) is responsible for securing a healthy natural environment and dealing with environmental risks.
It also promotes a sustainable, low-carbon and resource-efficient economy and ensures a thriving farming sector and a sustainable, healthy and secure food supply.
