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: are large hydroelectric power stations genuinely good for the environment?

15. February 2010, 08.40
After decades of planning, Belo Monte - the third largest hydroelectric power station in the world, will now be constructed in the Amazonas region of northern Brazil. When the Brazilian Institute of Environment and Renewable Natural Resources, IBAMA, approved the plan in early February, it was met with vociferous criticism from environmental conservationists and spokespersons for indigenous groups. So just how green are gigantic hydroelectric power stations really?

Energy question of the week: How does one turn a T-shirt into a power station?

Whenever the battery in a mobile phone, laptop or MP3 player goes flat, the desperate search for a power socket begins. A power source that everyone can carry with them at all times will provide more independence in the future – their own shirt. That your electronic equipment could ever be recharged by a piece of fabric does sound rather like a fairy tale. But is the 'T-shirt power station' really such an impossibility?

Energy question of the week: How long will our crude oil reserves last?

01. February 2010, 12.45
The global economic crisis has also had a positive side – the consumption of crude oil fell slightly in 2008 and 2009. Yet before long, it is likely to rise again to about 85 million barrels per day. The International Energy Agency's World Energy Outlook 2009 report states that demand will rise by a further percent each year to 105 million barrels per day by 2030. For how long can we meet this growing demand
