The nuclear power plant accident triggered by the Great East Japan Earthquake has drawn new attention to renewable energy. According to a study by the Ministry of the Environment, among the various types of renewable energy, wind power has the highest introduction potential by far with an installed capacity of 1.9 billion kW. However, introduction would require legal acts, supporting projects, and technological innovation. At Kyushu University, a large-scale demonstration facility for a wind power system called the wind-lens turbine was completed at the Ito Campus.

The nuclear power plant accident triggered by the Great East Japan Earthquake has drawn new attention to renewable energy. According to a study by the Ministry of the Environment, among the various types of renewable energy, wind power has the highest introduction potential by far with an installed capacity of 1.9 billion kW. However, introduction would require legal acts, supporting projects, and technological innovation. At Kyushu University, a large-scale demonstration facility for a wind power system called the wind-lens turbine was completed at the Ito Campus. While providing power to the campus, tests to increase the scale of the system will be conducted. For the next stage, Professor Yuji Ohya, one of the developers of this system, plans to build an offshore wind farm in Hakata Bay to conduct field tests, and also has a concept to establish a Multi-source offshore energy farm on the Genkai Sea in the future.

Check us out at www.tutorvista.com An energy source is a system which makes energy in a certain way, for instance a hydro-electric station. A hydro-electric station uses the current of the river for the making of electricity. Nowadays we need energy-sources for electricity. Without electricity no computers, no television, no washers. A lot of apparatus would not work without electricity. The three different kinds of energy-sources have their own pros and cons. In this part we give a few of them. •Nuclear power For the generation of nuclear power little raw material is needed to generate a lot of electric energy. This is an advantage, because the supply of the raw material will be enough for quite a time. A very big disadvantage is that the raw material for nuclear power, uranium, is very radio-active. Also the used rods en other used materials stay radio-active for ages. at a nuclear power plant as Tsjernobyl we have seen how dangerous this type of energy-generation can be. This is the major reason why environmental groups (like Greenpeace) are against this form of energy-winning. •Fossil energy The big advantage of fossil energy is that, to generate the energy from the raw material is easy and cheap. Disadvantage is that during the process of combustion a lot of toxic materials comes into the air which causes extra pollution of the atmosphere, these materials also increase the effect of global warming. Another disadvantage of fossil energy is that the supply of fossil ...

Question by Psssst! wanna send a letter?: What's the difference between a proper Solar water heating panels?
and household radiators painted black and housed in a cloche. Being a tight git I built my Solar water heating system for £180. It's three 1.2m x .6m panels, a pump and a controller. It gives me tons of hot water on a sunny day and does a bit even when it's not sunny. So whats the difference? Why do people spend £7000 on solar water heating systems?

Answer by BMS
first,

good job, it really isnt that difficult, but most people would rather pay than do the work...

second, from your picture, the water appears to be affecting you.....this may not be a good selling point.

good work!

Question by Fynnagin F: what colors should tubes be for a solar water heating system?
Solar energy can be used to heat water for a pool by running water through a series of pipes or tubes. What colour should the pipes be? What other features should this system have to improve its efficiency?

Best answer:

Answer by fill Yerboots
Matt black unless you are in a seasonally very sunny area. The black absorbs heat very well, so potentially it could get hot enough to boil the water if you are in an occasionally very hot climate. Some areas use pale colours because of this.
Black absorbs heat best, but also radiates it better than white or chrome surfaces.
