How to make a very easy solar hot water heater.

On March 28, 2009 at 8:30 p.m., local time, World Wildlife Fund is asking individuals, businesses, governments and organizations around the world to turn off their lights for one hour -- Earth Hour -- to make a global statement of concern about climate change and to demonstrate their commitment to finding solutions. Turn out. Take action.

The Carbon Trust believes that offshore wind power has the potential to supply 25% of the UK's electricity by 2020. To help make this happen, the Carbon Trust launched the Offshore Wind Accelerator, a ground-breaking research and development initiative. From 2003 to 2009 some 350 offshore wind turbines have been built at the rate of one every 11 days. They currently deliver about 1GW, whereas about 29GW will be required to hit the EU's renewable target for 2020. To achieve this, a further 6,000 turbines must be built at the rate of one a day from 2010 to 2016, rising to 2.5 a day from 2017 to 2020. They will be bigger and more complicated to install, standing in up to 60m of water, in some cases more than 200km from shore.
