Which energy source will we use in the future? DLR Energy Blog for ‘Energy’ Science Year

Can we refuel in the future simply using the Sun? How long will the Earth’s oil reserves last? Which energy source will our grandchildren use? Many people are asking scientific researchers about the future of our energy supply. The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) has chosen the slogan ‘The Future of Energy’ for Science Year 2010. In the DLR Energy Blog, science journalist Jan Oliver Löfken will answer a question about energy each week during the year. read more
