Saving building energy

Buildings last a long time (80% of housing and 70% of commercial buildings standing today will still be standing in 2050). Their energy consumption won’t change much in that time, so it is important that they are initially built to the highest thermal performance.

Scotland will tackle the problem by retrofitting new technologies to existing buildings, such as district heating, insulation, draught exclusion or changing lights to LEDs.

Other larger scale solutions include renewable energy projects such as biomass, wind turbines, hydro and solar. These free us from the volatility of imported oil-based fuels.

Global carbon dioxide is steady

A recent analysis by the Global Carbon Project has shown that carbon dioxide emissions have been steady for the past three years.

The situation can be seen with a positive perspective as the two major polluters: China and USA have over the last decade introduced policies and made changes in the way they operate to reduce their emissions, China by 0.7% and USA by 2.6%.

On the other hand, the emerging market of India has increased its carbon emissions by 6.3% and is aiming to double its coal production by 2020.

How energy is changing

Scotland’s energy mix has been changing over the past 10 years. Recent major changes have been the closure of the two remaining coal fired power stations and the steady increase in renewable generation.

Since 2007, Scotland’s total energy consumption has fallen steadily, down 14% (this comes from a 17% decrease in domestic and non-domestic buildings and a 9% reduction in transport).

In the same time, total UK energy consumption has fallen by 8.4% and in the EU by 6.4%.
