The combustion of fossil fuels increases the amount of carbon dioxide in the atmosphere, accentuating the greenhouse gas effect. This is recognised by many of the world's climate scientists as a major contributor to global warming.

Using energy supplied from renewable sources contributes to environmental protection by reducing reliance on non-renewable fossil fuels and reducing greenhouse gas emissions. Monitoring and optimising the use of energy, whilst maintaining the same quality and quantity of production, helps to achieve efficiency, with potential financial benefits.
