Potential and Application of Renewables
and Energy Efficiency in Industry
Energy efficiency in IT centres
IT = energy consumption = heat
IT components are very
sensitive to heat• In the past: 35 °C
• Now: 38-42°C
• In future: ? ?
Cooling • Room temperature in the past: 19 °C
• Now: 20-22°C
• In future: 26 °C
Cooling = additional energy
consumption

Potential and Application of Renewables
and Energy Efficiency in Industry
Energy efficiency second to none!
EU-wide economical saving potential of 20 % of current total energy consumption in industry branches
Top cost-cutting potential by efficiency measures – economically especially interesting for companies
High level of acceptance: 40 % of the medium-sized companies in Germany wanted to invest in energy efficiency measures in 2009. One of six companies plans on investing over 1 Mio. EUR.

Fields of application of renewable energies
Renewable energies are the logical second step!
Renewable energies can (partly) cover the remaining energy demand.
Environmental advantage, relief of energy costs, competitive advantage ...

Companies and enterprises – Total energy consumption and potentials
Potentials for renewable energies in companies
so far very limited distribution of renewable energies in industry and commerce
(e.g. just ca. 90 facility for solar process heat generation world wide)
high share of total energy consumption, of which are ca. 2/3 heat and 1/3
electricity
Process heat in low and medium temperature level (up to ca. 400 °C) has to
be covered by renewable energies = ca. 60% of required process heat!
Wide range for possible applications of different energy technologies with
renewable energies
Energy intensive branches can develop a competitive advantage by
decoupling form the oil price increase
Renewable energies themselves are a important future relevant branch!

Conclusion
High energy consumption of industry and commerce, rising energy prices
increase the pressure on companies to act
Increasing number of realised projects (best practice) provide security of
action, however, especially organisational obstacles still slow down the
market trend
By involving experts, use of supporting funding and network development
companies can implement energy efficiency and renewable energies
