2050: max. renewables, min. fossil fuels
Energy saving: 2% each year
CO2-reduction: 30% in 2020 (ref. 1990)
Renewables: 20% in 2020
Gas sector: Smart use of natural gas

• combinations with renewables
Centralised power production (60% gas)
Demand for electricity is increasing
Idea:
• generate electricity at home with gas
• small combined heat and power system
• microCHP

In 1995 a trip to New Zealand…
… first Stirling in 1996 to the Netherlands …
… and after some experiments …
… in 2003 arrived a serious Stirling
