• The chemical sector is energy intensive due to:
  – Energy intensive processes e.g. steam cracking to produce ethylene, benzene, propylene etc.
  – Feedstock choice: gas and increasingly coal due to high
  oil prices. Use of acetylene in VCM production.
  – Refrigeration, heating, etc.
  – Not energy efficient
• The chemical industry has been switching from coal to gas powered facilities as an efficient way of reducing CO2 emissions. This fuel switch almost halves the emissions of carbon dioxide due to the lower carbon content of gas.
• By capturing the heat from electricity generation and using it in the process, a CHP plant is nearly twice as efficient as the best conventional power plants
  through  power of carbon dioxide.
• The chemical industry is also pursuing reductions of nitrous oxide emissions (N2O), which are even more harmful than carbon dioxide when released into the atmosphere. For instance, the industry uses a catalyst which selectively destroys nitrous oxide when it is formed, cutting the amount of emissions in the combustion process by more than 90 per cent.
• Housing and transportation are two examples where chemistry has helped considerably to reduce energy consumption and thereby the impact on climate.
• Materials for house insulation, double-glazed windows and efficient ventilation systems are produced through innovations in chemistry.
• Refrigerators and other appliances are also far more energy efficient today than a generation ago. This is largely due to insulation materials made from chemicals, which have dramatically reduced the amount of electricity needed to run them. Better plastics and insulating materials have helped to improve the energy efficiency of refrigerators and air conditioning equipment by 30 to 50 percent since the early 1970s.
• Compact fluorescent light bulbs:  produce the same amount of light as a conventional light bulb whilst using 70% less energy. In addition, they last between 10 and 20 times longer. Again, chemistry is behind this innovation. The inside of the light tube is coated with the chemical product phosphor - a powder that “fluoresces” (gives off light) when stimulated by ultraviolet radiation, thus producing visible light
• Significant progress is also being made in the field of transport. It is estimated that 100kg of plastics have replaced 200-300kg of conventional materials in a typical
  car over the last decades - saving 750 litres of fuel every 150,000 km. Each year that equates to 12 million tons of oil saved across Europe.
