               Energy Turnaround:
       The government new 6-point program
1. Quickly enhance Renewable energy
Core of the energy turnaround is the rapid expansion of renewable energies. The wind energy
has the biggest potentials.
2. Quickly develop electricity grids and storages ...to transport electricity from wind power
plants in the north to the south. Expansion of flexible power stations and storage, serving to
stabilize the power supply.
3. Consistently increase Energy efficiency
By 2020 the heat demand of buildings shall be reduced by 20 percent. Encourage an
ambitious renovation.
4. Quickly build flexible power plants
In future, flexible power plants must offset the increasingly fluctuating power generation from
renewable energy sources. Gas power plants have a special role. The construction of highly
efficient and flexible power plants will be promoted in accordance with EU requirements. This
is limited to operators whose share of the German power generation capacity is up to five
percent.
5. Reorienting Energy Research
The funds for research into networking and storage should be increased to 500 million € by
2020.
6. Participation of Citizens
People should be fully involved to enable a broad dialogue on the necessity of restructuring
the energy supply.

            Summary and main results
• Energy efficiency is a core element of a sustainable energy
  strategy
• Conventional heat production in boilers is a big waste of
  exergy
• CHP is a core element of an energy efficiency strategy
• CHP is being discovered more and more by policy makers
• CHP has a large potential - in Germany and anywhere
• The Target of doubling CHP in Germany is a big chance for
  industry and investors
• We have to make our choice on the future electricity
  production path – in fact environment tells us that we don’t
  have a choice
• By using CHP potential and by overcoming barriers against
  CHP we may learn from each other
