Energy question of the week: Does the future of wind power lie in the open seas?

26. April 2010, 08.34
In January 2010, wind farms in Germany had a generating capacity of 25,777 megawatts. This means that almost eight percent of Germany's electricity requirement can be met in a climate-neutral way. However, since land areas exposed to strong winds are limited, both large and small-scale power-generating businesses are jostling for position out in the open sea. This poses a simple question: are offshore wind farms genuinely more efficient?

Energy question of the week: How much electricity could be generated from ocean currents?

21. April 2010, 10.37
Electricity has been generated from tidal power for decades. Large installations could supply entire towns and cities. However, tides are not the only forces moving water in our seas. Ocean currents also move huge amounts of water all around the globe. Is it worth exploiting this power source?

Energy question of the week: Is it possible to fly on nothing but solar power?

12. April 2010, 08.33
In cruise ships, electrical propulsion units – powered by diesel engines – are now standard equipment. Every day, buses with electric motors powered by fuel cells ply the streets of Hamburg. Now the first aircraft powered solely by electric motors are taking off. However, in the quest to find exciting, original and climate-friendly propulsion, are solar cells powerful enough to get an aircraft off the ground?

Energy question of the week: How is electrical power carried across the sea?

06. April 2010, 08.07
Two trends are emerging for future renewable electricity. In the first, local solar, wind or biomass plants will produce more energy for small communities or single homes. In the second, large amounts of electricity will be generated by solar power stations in desert areas or extensive offshore wind farms, and delivered over long distances to densely populated areas. But how can electrical power be delivered over long distances without large losses?
