Food is essential to human existence and it is an integral part of a low carbon economy. Food miles, artificial fertilizers, organic production, mono cultures, food vs. fuel and industrialization are all issues for consideration in the wider context of ‘low carbon food’. Growing food increasingly relies on agro-industry using machinery, pesticides, artificial fertilizers and even genetic modification.

Even simple food crops now have significant embedded carbon factor, and the carbon cost of agriculture is further increased by factors such as clearing of natural habitats to make room for farming (and the subsequent loss of biodiversity), the use of mono cultures that damage the land (and cause future reliance on technologically-driven agriculture) and transportation of the produce. On the other hand, agriculture can also provide bio-fuels and biomass which are sure to play a part in the future energy mix. - Description added by: David Lockie

Heating and cooling are typically extremely energy intensive technologies. In the United Kingdom the majority of heating in our homes and buildings is provided by burning natural gas. Renewable energy technologies such as solar heating, or heat pumps provide a sustainable low carbon alternative. Condensing boilers, and combined heat and power (CHP) also offer significant energy savings. In this circumstance energy that would have otherwise been wasted (which happens in traditional power plants) is instead used by the local community via a district heating scheme. Alternatively, a micro CHP system (such as a residential fuel cell, or Stirling engine) produces both electricity and heat to serve a local heat demand i.e. for a particular building. Energy efficiency technologies such as low carbon ventilation solutions can reduce the energy demands of buildings. - Description added by: David Lockie

Transport is responsible for a large proportion of carbon emissions. As high carbon fossil fuels are largely used to power all types of transport - from road to rail, marine to aviation - carbon dioxide and other greenhouse gases are released into the atmosphere, contributing to climate change. Using public transport and technologies to improve energy efficiency, hybrid vehicles, electric vehicles, bio fuels and fuel cell vehicles are all vital components in helping to reduce our carbon emissions from transport. - Description added by: David Lockie

Renewable and alternative energy sources are set to play an increasingly important role in providing the electricity, heat, cooling and fuels that society needs. There is a wide range of energy sources such as solar (both photovoltaic and solar thermal), wind, bio-fuels and biomass, hydro-electric, geothermal and heat pumps. - Description added by: David Lockie
