Councils and other public sector bodies are being urged to generate renewable energy and cut their emissions.
The Environment Agency said the public sector could provide energy for up to 1.5 million homes by reducing its own output.
As such, government agencies are being urged to energy technologies such as wind turbines and hydropower schemes
More than ten per cent of UK land is currently owned by public sector bodies.
Tony Grayling, the Environment Agency's head of climate change and sustainable development, commented: "Investment in green technology such as wind turbines not only help cut carbon emissions and secure more home grown energy - they also make financial sense to those involved and ultimately save the taxpayer money."
It is now more important than ever to look for alternative sources of energy to meet our demands, he added.
Meanwhile, the Environment Agency announced yesterday that it has begun trialling a new electronic waste tracking system with a number of businesses in the south-west of England.
