Hello everybody, today I will present you ( 😉 Flo 😉 ) a good solution to use a wind energy
The solution, as many see it, is to make these farms farther out to sea, where the wind is stronger. The resource is more interresting. Aside from the transmission challenges that come with deep offshore wind, the biggest objective is how to anchor these wind turbines without fixed foundations
The floating structure it’s a best engineering and construction challenges at more shallow depths. Because the deep water structure are designed to float, they can essentially be assembled on shore and towed to their final destination, with much less work performed directly on site.
Right now, offshore wind plans are concentrated along the East Coast.
In the moment, this is the first offshore wind turbine in Atlantic waters, and the first deployment of a semi-submersible structure supporting a multi-megawatt wind turbine.
Today, I will you present advantages and disadvantages of the water energy.
- Electricity can be generated constantly.
- Once the dam is built, the energy is virtually free.
- No waste or pollution produced.
- Much more reliable than wind, solar or wave power.
- Water can be stored above the dam
- Hydro-electric power stations can increase to full power very quickly, unlike other power stations.
- The dams are very expensive to build. However, many dams are also used for flood control or irrigation, so building costs can be shared.
- Building a large dam will flood a very large area upstream, causing problems for animals that used to live there.
- Finding a suitable site can be very difficult – the impact on residents and the environment may be unacceptable.
- Water quality and quantity downstream can be affected, which can have an impact on plant life.
Unlike other renewables such a wind and a solar power energy that receive more praise than criticism, hydropower is a highly controversial issue. While it does have many merits, it too is like so many other sources of energy if we ignore the critics’ warnings, we may not realize its full impact on our natural resources until it is too late.
I will you present the other energy renewable, the Wind Energy.
The next picturen present the principe to transforms the wind into electrical energy.
The usage of wind turbines to produce energy is constrained to installing them in wind areas where wind flows with high speed as otherwise wind cannot be utilized to produce energy. To generate energy, humans have been harnessing the wind since a long years. But today’s modern wind turbines continue to become more productive and powerful as they supply energy to hundreds of homes than the windmills used in old days which were good enough to produce energy only for small jobs like recover water from sea or grinding grains.
Today I will you present the solar energy. In a first time, below it’s a picture to present how solar energy is recovered.
For me the sun is the most important source of energy. The sun rays can be used as a mean of producing the energy. Photovoltaic cells possessing the characteristic of converting heat to energy are used to generate electricity. When sun rays strike the surface of these photovoltaic cells, electric current is produced.
But the principal problem it’s the price. This device is also less expensive as it is made up of silicon which is one of the most abundant elements on earth.
See you soon for the new information.
I will present two companies using renewable energies for heating or cooling a home :
SARL Thiel & Lambert, the company uses water power. It’s allows to use heat water. The advantage is that this energy is available all the time. The disadvantage is that you must be next to a water source to recover power.
SOLAIRESUD this entrerpise proposes to use the sun to heat the house. This is a very economical and convenient way when there is a large area available. The advantage is that the sun is available everywhere (almost) and the disadvantage is the high price.
I have found a website to teach young people about renewable energy
I think it’s a good idea to teach it to children. In this way, they can want to find a jobs in renewable energy when they grow up. Moreoverthis way of presenting the problem can show to the next generation. The training is fun. Because those children suggest different solutions with different available energies (Solar oven, wind turbine, hydro generator , biogas generator).
A competition is organized in Canada and the topic is the renewable energy. Different classes every year which challenges participants to build, test and bake with solar ovens.
For me it’s a great idea, funny and interesting.
We will see during the next few years the progress of renewable energies in the world …
Hello Ecologist energy,
Today I’m going to present you the distribution of energy. The diagram below, present the energy uses.
The table below, presents different energies. It’s very interesting, because we can see the increase of the renawable energies use. It’s very good for the world but it’s not enought for the moment.
|Investment in new renewable capacity (annual)||130||160||211 billion USD|
|Renewables power capacity (existing)||1,140||1,230||1,320 GWe|
|Hydropower capacity (existing)||950||980||1,010 GWe|
|Wind power capacity (existing)||121||159||198 GWe|
|Solar PV capacity (grid-connected)||16||23||40 GWe|
|Solar hot water capacity (existing)||130||160||185 GWth|
|Ethanol production (annual)||67||76||86 billion liters|
|Countries with policy targets
for renewable energy use
See you later for other information in the EnergyBlog 😉
Hello every body
The subject of the blog is the renewable energy. It’s very interesting for the world. In this blog, I will present a different energies, and news of renewable energy.
Nowadays, it become more and more important to recycle energy so I think that the renewable energy is the future of energy.
Have a nice visit in my energy blog
