Over theyears, there have been working on ways to create more sustainable energytechniques. One technique that is discussed often is Biofuels. The wayBiofuel energy is created is by burning organic matter. Biomass is the solidform of ‘bioenergy’, but liquid fuels could also be created from plant matterand this is mentioned to as ‘biofuel’.

Biofuel creates carbon emissions, asbiomass is carbon based. On the other hand, the carbon that is released duringcombustion is equal to the amount that was absorbed while growth, and so thetechnology is carbon-neutral. Therefore, instead of burning fossil fuels tocreate petrol, biofuels are an efficient replacement in cars and trucks duringthe construction of the new development in Headley. A source of Biofuel iscellulose and vegetable oil crops such as palm oil and rapeseed can also be managedto create liquid fuel. In addition, animal residues from cattle, chicken andpig waste can be transformed to bio-energy by adaptation to gas or other fueltypes.Another energy technique isWind Power.

The energy source is the wind and the power of the wind determineshow efficient the energy is. Wind Turbines are used to transform the wind intoenergy. As the new development in Headley is in a rural area, it is suitable touse wind power. Having a wind turbine close to the building would normallyhave peak outputs of up to 10–20 kW. 6 kW is a mutual size for smallerbuildings, and would usually be expected to produce around 10 000 kW·h peryear, reducing carbon dioxide emissions by more than four tonnes.

Wind turbinesare generally known to be one of the best cost effective renewable energytechnologies. Furthermore, the UK has one of the windiest climates in Europe,and this makes it perfect to use in the new development.In recent times, buildings are using renewable materialsmore and more. This technique is getting popular and steadily developing astime passes by. The reason why this is more preferable is that it decreases theover reliance of non-renewable resources. In addition, a few more reasons are:–         Reduced embodied carbon content –          Reducedwaste –          Socio-economic benefits-          Improvedconstruction performance –          Insulation materials (improved performancewhen damp) –          Localprocessing/manufacturing –          Healthierbuildings –          Enhancebiodiversity  A type of renewable material that is used frequently in the industry isInsulation.

Conventional Insulation is made up of Fibre glass, polystyrene, polyurethanefoam and multi-foils. A building that is well-insulated cuts down energy billsby maintaining the building keeps warm in the winter and cool in the summer. Sotherefore, this results in a cut down of carbon emissions linked to globalwarming and climate change.  Cellulose is a recycledproduct made from newsprint and other cellulose fiber. Builders seem to preferthis technique because it can be easily blown into cavity walls, floors androofs. Waste could be reduced in our world,as Waste is expensive.

One way to hit that goal is to take the approach ofrecycling. Recycling waste from households could later be generated into fuels.In addition, glass could be recycled to create aggregates, decorativematerials, fluxing agent in the manufacture of bricks and ceramics, filtrationmedium, insulation and abrasives
