What can I choose in the calculator?

The calculator lets you choose the energy efficiency in the swiss industrial sector in the selected year (2035 or 2050).

IMPACT – What is the impact of increasing the energy efficiency in industry?

In Switzerland, increasing the energy efficiency in industry will have the following impacts:

Energy system

image Reduces final energy demand.

image Likely to reduce total electricity consumption.

image Likely to reduce total fossil fuel consumption.

image Likely to increase energy independence and energy security by reducing fossil imports.Likely to increase energy independence and energy security by reducing fossil imports.

Environment & Climate

image Very likely to reduce global CO2 emissions.

image Focus on energy efficiency likely to also result in related resource savings as a side-effect.

Society & Economy

GLOBAL MARKET – What is the global potential for increasing the energy efficiency in industry?

Analysis by the Rocky Mountain Institute suggests that the energy intensity of US industry could be reduced by a factor of more than 2 by 2050 relative to 2010.[1] Considering that global industrial energy demand represents about 30% of total final energy consumption and is forecasted to remain at that level,[2] such an improvement in energy intensity could have a very substantial impact on global CO2 emissions if the efficiency improvements are adopted widely and rapidly.

DEFINITION / CONSTRAINTS

DEFINITION - What is Industry Energy Efficiency?

This indicator reflects the way heat and electricity are used in industry. The major industrial energy demands come from process heat requirements and for electric motors that drive equipments. In 2012, about 42% of the industrial final energy demand in Switzerland was for electricity, and a further 43% was met by fossil fuels.

Industrial efficiency measures can result from process and process equipment improvements, and waste heat recovery.

CONSTRAINTS - What are the key barriers facing the increase of efficiency in industry?

• Low energy prices often make the economics of equipment or process improvements very challenging as the monetary value of the energy savings is small.

• Energy efficiency improvements would often need to be made by refurbishing existing industrial plants, which is typically less cost effective and more challenging.

ASSUMPTIONS – WHAT ARE THE ASSUMPTIONS CONSIDERED IN THE CALCULATOR?

The [[industry_energy_intensity|industry energy intensity]] is calculated assuming several parameters. The main assumptions are: * Evolution of the [[industry_energy_intensity|energy intensity]] for twelve types of industry (food, clothing, paper, chemistry, etc). * The evolution of the [[swiss_industry_mix|Swiss industry mix]]. It is necessary to forecast the production of each type of industry in order to be able to determine its weight in the Swiss industry production and calculate its contribution into the average energy intensity. E.g. the paper industry had an [[industry_energy_intensity|energy intensity]] of 3.50 kWh/CHF [3] in 2011 and it is assumed that in 2050 it will be around 4.5 kWh/CHF [3]. In spite of the increase of the [[industry_energy_intensity|energy intensity]] of the paper industry, the Swiss average value is expected to be lower. This can be explained by the fact that the paper industry production will decrease, while other industries with reductions on the [[industry_energy_intensity|energy intensity]] will increase their production. As it is the case of the chemical industry, whose [[industry_energy_intensity|energy intensity]] will go from 0.48 kWh/CHF [3] (2011) to 0.2 kWh/CHF [3] (2050) and its production will be 30% [3] higher (2050 respect to 2011).

VALUE RANGE - WHAT RANGE OF VALUES CAN I CHOOSE?

The expected future value ranger for the average [[industry_energy_intensity|industry energy intensity]] are: * 2035 -> 0.20 – 0.25 kWh/CHF * 2050 -> 0.15 – 0.20 kWh/CHF In 2011 the Swiss [[industry_energy_intensity|industry energy intensity]] amounted to 0.34 kWh/CHF in average [3].
