Windmills Power - New Alternative Energy Source
Author: nuno ribeiro
A windmill is actually a machine which driven by the power of the wind. It consists of blades or sails, which generate to convert the wind energy into other form of more useful energy such as electricity or power to pump water.
Back then in the middle ages Europe, windmills were used to mill or grind grain. This is where the original word of ‘mill’ derived. It had a simple type of windmills consist of poles with blades. Centuries later, it turned into tower mills which took shape as windmills with tower in its based and a rotator on top of it. Tower mills known as ‘torenmolens’ in Dutch. It performed much better work than the previous windmills since it could farm even in a lower wind.
In the industrial revolution era, steam and engines replaced windmills. But for some countries windmills are preserved as antique machinery for their historic value. The original use of windmills nowadays is usually done in ranches in remote area that has less connection with latest technology.
The interesting part is that the world has changed when the prices of energy increases very high. People tend to go back to the use of windmills for the sake of saving their pocket and preserving the environment at the same time.
The necessity of less cost energy pushes companies to find effective way to create new source of energy. They went back to windmills and build ‘windfams’ as their alternative commercial energy for production. Now modern windmills equipped with turbines or generators to generate electricity. They can produce electricity up to 6 MW of power or similar to 500 - 1,300MW for conventional power plant.
Other type of windmill usage is a windpump. As it sounds, a windpump is used for pumping water from soil. It’s largely used in Africa and has a function to supply water for human and animals. Particularly in countries where lies above sea level, windpump is functioned to drain the land, as it did in Netherlands, some part in United Kingdom, and also in East Anglia.
A windmill has thermal and electric power output which produces by windmill’s blade rotation. They are mounted and connected to a speed increaser machine and compressor that moved by wind applied to the blades of the windmill itself. To produce electricity, a gas turbine generator should be connected to the compressor. A windmill can generate power or heat by adding impeller type of air brake and a valve and also a heat-sensitive control.
Here are the windmill power specifications for generating electricity:
1.It has a function as an electricity generator.
2.Minimum wind speed is 10 km/hr.
3.Maximum wind speed is 50 km/hr
4.Rotor specifications are: blade made of aluminum with 3 m in diameter, its framework made of bagel steel.
5.Body specifications are: tail model pointed to the top, frame work made of hollow steel.
6.Tower specifications are: 10 m in height, it has L stripe steel framework.
7.Generator specifications are: direct current electricity generator with power range from 1000 watts, 2000 watts, to 5000 watts.
Windmills, which use as alternative energy sources will play a great part in replacing fossil fuels power plants. It’s renewable and clean for the environment. It even helps us to create better climate in the future. Wind is free to get and produce no pollutions to earth, which can make our environment healthier for generations to come.

Major oil companies are already invested in renewable energy. Read this article.

It says Exxon-Mobil committed $600 million toward fuel from algae. Another oil company, British Petroleum, is one of the largest manufacturers of solar panels. It doesn’t upset me one bit that oil companies are diversifying into other forms of energy. I hope they make lots of money from it because if it isn’t profitable they will stop and we will continue depending on foreign oil.
Biomass -
it not that they need to be promoted
we are all aware of them and there benefits
what needs to be done is changing laws to allow them to be utilized by the common man
example
we own a medium farm, decided to put up a huge kw windjammer, aren’t allowed to because county law says no structures over two stories, county law also allows the public utility to not pay you for excess electric generated and you have to pay for the reverse hook up – now how does that promote green energy, it doesn’t it punishes for going green, now we have to do all kinds of stupid stuff to hide our alternative energy supply, and still are required to be on the grid. our goal was to be off grid by now, and possibly put up additional jammers to produce a very small profit, like maybe mcdonalds once a week.
so start there – get the laws changed so we can do what we want and stop letting government control what type of energy we use, make, consume
Probably chemical engineering. For that chemistry, and all of its requisites. Perhaps some other forms of engineering too. For that you’ll need physics and math, along with all of the engineering mechanics.
The one answer you got is typical of a so called conservative.If it ain’t broke,don’t fix it.Well our energy program is broke,and it need fixing.I won’t care if there was a wind generator on ever block in the united states if it would get us away from fossil fuel.Isn’t it amazing how the auto companies are falling in line with their electric models and hybrids.There excuse has been that the public just wasn’t ready for them.How do you know if you don’t offer them.The big three has been in bed with big oil for years.They are beginning to see the writing on the wall and hopefully will continue to build better models.
would you be upset if a major oil company discovers a new renewable energy source and makes billions off of it?
India has formed a Ministry of New and Renewable Energy, are Western countries following suit?

How can new and renewable energy sources be promoted?
I want to focus my studies on new energies?
I’m currently in high-school, and I’m wondering what specific subjects I should focus on in order to prepare for a career pertaining to new and renewable energy resources. What subjects should I want to learn now in high-school, what subjects will I want to focus on in college, and what colleges will be beneficial to this area of study?
This may not be the best category for this question, but I put it here because I thought the maths and sciences best pertained to this subject.
The second fastest growing new renewable energy source is ________.?
biomass
solar
wind
geothermal
ocean tides and currents
