 The Commission also recommended that the government should not sanction the creation of a national natural gas infrastructure, on the belief that this would inhibit the development of biofuels and encourage the use of gas in place of oil.To cut energy use, the commission anticipated that by 2020 at least 75% of all new housing would use low-energy building techniques similar to the German Passive house standard, and that it will also be necessary to modernize the existing housing stock, including replacing direct electric heating systems (with systems heated by district heating, biofuels or heat pumps).They also expect there to be a greater use of teleworking, video conferencing and web conferencing, public transport, sea transport, hybrid vehicles, and smaller, lighter, biodiesel cars.
