- Edwin L. Drake succeeds to find fossil oil for the first time in a 20m deep hole
- coal dissolves wood as GGS
- fossil oil also known in central europe
-> as healing
- Egyptian use windpower
- fossil oil is used by many old cultures as healing and fuel
- fire gets discovered
- wood and sun are important suppliers of energy
-the large part of the world energy demand is covered by wood
- natural gas has the biggest growth of the fossil fuels
in Wietze at Celle :
-> first time drilling for fossil oil - unsuccessful
- fossil oil and natural gas gain more and more importance
