# Sustainable energy generation

Natural gas is the cleanest among the fossil fuels – which is why the emissions from the power generation process are significantly lower than those of other fossil-fuelled power plants. The combined gas and steam cycles are built such that the maximum energy is extracted from the natural gas.

The CCGT process is very flexible: fast start-up and shutdown of the plant makes CCGT plants the preferred technology to provide electricity when demand is high, or to balance fluctuations from renewable energy sources, such as from wind and the sun, which are not always available. This is the reason why CCGT generation is the ideal partner to integrate more renewable energy sources in the power grid and keep the electricity grid balanced.
