Use of Solar Energy Around the World
Male: This is Europe center for solar energy research and development in Utamaro, Southern Spain. It is pioneering technologies that could ultimately be used to power large towns or industrial complexes. In this system, a huge array of mirrors reflects and concentrates light to a single receiver at the top of this tower. The resulting energy can turn water into super heated steam, enough to power a high output generator.
Manuel Muriel: This mirror reflects move in such a way that reflects the light from here that goes into the mirror towards a central receiver system on top of the tower. Concentrating the light that comes over all these mirror into one receiver.
Male: Other systems replace water for gas.
Michael Geyer: In this receiver, we have a working gas. It’s heated up here to about 650 degrees centigrade, and leaves the receiver at this temperature and enters here the cylinder of this sterling engine, where it performs the mechanical work and drives the generator.
Male: This is the cutting edge of solar research. But to prove, it’s not just the theoretical technology. There is a town in Germany known as the “solar city”, Freiburg, in the black forest of Southern Germany. It may not have the sunniest skies, but it does have the sunniest power. Rolf Disch is the architect of many of Freiburg’s solar buildings including his own home.
Rolf Disch: This is an experimental house. With this house, we’ve tackled many problems. One of this is energy. This is the first surplus energy house that we’ve built, which produces five times an amount of energy that the house needs.
Male: Disch now builds solar powered, low energy houses for others. These are the first of 150 that make up Freiburg is the first solar village. The whole city is involved in Freiburg’s solar policy as even as solar plant on the grandstand roof of the local football stadium.
Naturally, the public swimming pool is heated by solar power, and the parking meters are also powered by solar power. With Freiburg reaping major economic awards does a booming demand for new solar technology. At the factory where much of the hardware is made, solar power modules and the glass façade plus a power plant fueled by vegetable oil together give enough energy for the whole building.
There’s even a solar café. It has a roof made with semi transparent solar panels. Then at on the roof, they isle the roof. They let in sunlight and give the architect greater flexibility in design. They parted the building materials, panels at the solar future.
But solar power needn’t be about large scale projects. This congregation of fifteen in Kenya has led by a single solar lantern, enough to allow the service to go ahead. And more important, to give Steven enough light to read the scriptures. Kerosene is out, solar power is in.
Designed by the Intermediate Technology Development Group, ITDG, Steven’s lamp is easily charged by Kenya’s powerful and plentiful sunlight. A day’s charge will give four hours light at night. It used to take Steven and his wife two hours every time they had to collect that kerosene.
Jane Njenga: The lamp has many advantages. I don’t have to buy kerosene and it’s portable. I can use it when cooking and for checking the children’s rooms. We leave it on until ten then it take it to the --.
Male: Before, the solar lantern normal life came to a stand still off the dark. Now, David’s family can do old sorts of things at night. The lamp is simple to operate but costs just over US $100.00. That’s a big investment for a poor family in the countryside but eventually the light is free. Another bonus, you can even plug a radio into it.
John: This being lighted is brighter than even a torch. The light is very bright. You can see every corner of the compound.
Male: When John has finished with the light for the evening, the chickens get a little more lying time. At the other end of the continent in South Africa, a scheme developed by Shell in partnership with Escon, the South African National Electricity Company and a local manufacture of Conlog is showing that solar power can be cost- effective for the rural poor. It has some importance supporters.
Male: By connecting homes with the country’s electricity grade is getting very expensive especially as we get deeper and deeper into the rural areas. Alternative vessels have become important. That is why we couldn’t force support to efforts made by Shell and Escon to bring our people electricity through to solar home safety, which is safe, affordable, and friendly to the environment in which we live.
Male: It’s the largest commercial, solar rural electrification project ever undertaken. The target is to light 50,000 homes. So far, 1400 homes have seen the light. The installation costs the equivalent of US $30.00 and the running costs are US $8.00 a month. This goes towards the purchase of the magnetic card which activates the unit for 30 days. The gauge shows how much time you have left. When fully charged, the system provides power for TV, radio, and full lights for up-to four hours. Once the lead is on, Pomape Papoos starts the system.
Flaeiephi Dlamini: I bought this so that when I’m dead and gone, I will leave something behind for my grandchildren which is wonderful especially its something I didn’t have.
