  THE GREENENERGY WEBSITE 

  http://www.nef.org.uk/greenenergy/index.htm

  Did you know.? At present over 2% of electricity produced in the UK comes from a renewable source. By the year 2010 the Government's target is to exceed 10%. Various predictions suggest we will achieve ... 50% by the year 2050. Some renewable energy sources rely on the availability of natural occurring energy. These include heat or light from the sun; wind at a suitable speed produced from complex weather systems; waves from oceans, and tides based on the relative position of the sun and earth. These cannot be turned on or off according to demand for energy; they are therefore said to suffer from intermittency. Although a degree of back-up is required to cope with intermittency, a report prepared for the Carbon Trust in 2006 identified that intermittency should not be a major problem in the UK over the next 20 years. Please follow this link for more details on intermittency . To download our education factsheets on the different renewable energy, please visit our education website at ww   [More...] [Less...]

  Energy Resources: Solar power 

  http://www.darvill.clara.net/altenerg/solar.htm

  We've used the Sun for drying clothes and food for thousands of years, but only recently have we been able to use it for generating power. The Sun is 150 million kilometres away, and amazingly powerful. ... Just the tiny fraction of the Sun's energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over. In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly. Solar Cells ( really called "photovoltaic" or "photoelectric" cells) that convert light directly into electricity. In a sunny climate, you can get enough power to run a 100W light bulb from just one square metre of solar panel. Solar water heating , where heat from the Sun is used to heat water in glass panels on your roof. This means you don't need to use so much gas or electricity to heat your water at home. Water is pumped through pipes in the panel. The pipes are painted black, so they   [More...] [Less...]

  A ray of hope for developing countries - icWales 

  http://icwales.icnetwork.co.uk/business-in-wales/business-news/2007/11/23/a-ray-of-hope-for-developing-countries-91466-20148515/

  A COMPANY making next-generation solar technology used to charge mobile phones yesterday announced its first order. Cardiff-based G24 Innovations – G24i – said a deal for its mobile phone chargers, centred ... around its revolutionary solar technology known as Dye Sensitised Thin Film (DST), has been made with a company in Kenya. G24i has a strategy to first target markets in the developing world, where people in remote areas have little access to reliable power sources. Company chairman Bob Hertzberg – a former speaker of the California State Assembly – has formulised the plan because of the massive need for communications technology, coupled with dependable power, in the developing world. G24i’s chargers will be pioneered by Master IT in Kenya. Last month G24i, which is headquartered in Wentloog on the outskirts of the Welsh capital, announced the world’s first production of commercial grade DST solar cells, marking the commercialisation of 18 years of research and development in the tec   [More...] [Less...]
