Mediterranean plastic greenhouses are generally used in areas with high radiation and favourable temperatures, allowing almost year-round production of tomato, sweet pepper or cucumber. The use of fossil energy for heating is negligible. However it is expected that there will be a gradual increase in the application of artificial heating in greenhouses. This even can add to sustainability, since it will allow the optimisation of other product factors like fungal diseases due to humidity. Currently the heated greenhouses are usually high tech greenhouses heated with natural gas, but there are clear commitments to limit the use of fossil energy and seriously search for alternative sources, such as biofuel or new applications of solar energy.

East Asia
In the context of greenhouse gases and sustainability there have seen various shifts and developments in recent years. Many East Asian countries, including China, Japan, and South Korea, have been increasingly investing in renewable energy sources like solar, wind, and hydroelectric power. Despite the push for renewables, coal remains a significant energy source in East Asia, particularly in countries like China and India. However, there's a growing emphasis on reducing reliance on coal due to its significant contribution to greenhouse gas emissions and air pollution. Many countries are investing in cleaner coal technologies or gradually shifting towards cleaner energy sources.
