'The Future of Energy' Year of Science: A different question every week, 1 answer and 150 comments

29. December 2010, 11.00
During 'The Future of Energy' Year of Science, DLR prepared one question each week on the topic of energy, answered by the science journalist, Jan Oliver Löfken. Users were invited to post their questions and comments on the blog, and we responded as they came in – we received a total of 150 contributions. Read 51 posts on our Energy Blog and see how researchers want to safeguard our energy supply in the future and what policies are being put in place for this in the world of politics.

Energy question of the week: Will our appetite for energy continue to increase?

27. December 2010, 10.33
Our energy demand can be split into three main areas: electricity, heating, and fuel for mobility. In Germany, every person needs about 6000 watts of power to maintain his or her affluent, mobile way of life. Americans use almost twice that amount. Compare that with people in developing countries, like Chad, who only have 11 watts at their disposal. Is there a need for more and more energy?

Energy question of the week: How much electrical power can be harnessed from tides?

22. February 2010, 08.02
Under the influence of the Moon's gravity, the water of Earth's oceans rises and falls twice a day. Powerful forces are at work all over the globe between every low and high tide – forces that can be harnessed to generate electrical power. Just how mature is the technology and what is the potential that tidal power stations could unleash?

Energy question of the week: How much energy does the Sun send us every day?

12. January 2010, 11.30
Our Sun is a gigantic fusion reactor with an expected lifetime of about ten billion years. Although this period of time is unimaginably long from a human perspective, half of it has already elapsed. That means that our star, a very ordinary one in astronomical terms, will still be radiating the same amount of energy as it now does long after our resources of uranium, coal, gas or crude oil have been used up. How much energy from the Sun reaches us here on Earth?
