Take solar or wind energy for example. We already know how to harness and make it. If you want to make one, do some research online and then set up the system yourself.

To have solar energy, you will need to buy an inverter, battery, charge controller, solar panels, some wires and support structure. The only difference with wind  energy is that you need a fan. Once you have everything you need, you can put it all together.

If you are not skillful, you will be happy to know that some companies sell the entire system. By buying it from them and having it installed by their experts, you are sure that there won’t be any problems the moment you switch it on.

There is one more thing you need before you can use one or the two green energy sources. Before you buy the materials or the system, make sure you have a flat area that is about a hundred square feet or so because it occupies a lot of space.

For those who don’t have the space or the budget to use these two energy sources, another option is to create your own biofuels.

Biofuels are used in many countries and they get it from harvesting corn, sugar and other crops. Luckily, you don’t need a farm to produce it because you can also make your own using some recycled waste.

A good example of this is vegetable oil which we use for cooking. To turn this into a biofuel, we first filter it by warming up the liquid and then filtering this with a coffee filter. The next step is to remove the water also by boiling it again at 100 degrees for a short period of time.

We need to know the amount of lye present in the vegetable oil and we do this by a process known as titration. When we are done with that, we now mix sodium hydroxide to produce sodium methoxide.

The process of converting used vegetable oil before it becomes a biofuel takes quite awhile and it must be heated the entire time. This is done so the fuel we produce is pure and only when this is achieved that we give it time to cool.

Just how much biofuel we make after all the work varies but you will have an idea of how much you have produced since this is the one you see floating at the top. If there is still some glycerin present, filter it again. From there, you already have your own backyard biofuel which you can use and even sell to those who are just as concerned with the environment as you are.

By making our own green energy sources, we make ourselves less dependent on gasoline in its various forms to power our heater, home or car. Why don’t a lot of people do it? Well simply because they don’t have the time to make it and would rather rely on someone else to do it for them.

Sustainable Power Of The Wind

With so much talk about environmental damage, dwindling fossil fuels, and sky rocketing oil and energy prices it is now clear that we must look for alternative energy resources that will be able to supply our endless needs without the possibility of it being exhausted.

A Brief Lesson in History

A sustainable energy source since ancient times, the power of the wind has been harnessed by sailors, farmer, and architects alike. In times long gone, from 5,000 years ago and rediscovered again today the Egyptians used wind power to propel their sailing vessels, and Babylonian architects use architectural designs to make use of the wind to ventilate their palace and temple complexes.

As early as 300 B.C. the Sinhalese bygones used monsoon winds to power their furnaces. Constructed right where monsoon winds pass the furnaces were powered up to 1100 to 1200 centigrade. In the 1st century AD the first ever primitively built windmill was used to power an organ. Later during the 7th century the first and most primary windmill was built in Afghanistan in a small town called Sistan. The Windmill has a vertical axle with blades shaped like a rectangle and with a long driveshaft. In the 1100’s wind mills were built to grind flour, for sugar manufacturing and the gristmilling industries. The Dutch built windmills that stand until this day.

Beneath Power Is Wind

The Sun unevenly heats the Earth that differences of heat distribution; the poles receive less than the equators do. Unlike the land, the oceans, seas and rivers do not have covering so it retains more heat than soil. This contrast results in a global atmospheric convection that reaches from the stratosphere and into the earth’s surface. Energy in these wind movements are stored at high altitudes where in the wind can achieve speeds up to 160km/hr. Here after with the effects of friction the wind’s energy is diffused into heat throughout the planet and its atmosphere. This vast amount of sustainable power can provide us unimaginable amounts of energy, far more than we currently consume.

Wind Speed Distribution

Wind varies in strength.  The average value of a certain location does not specify the energy of a single wind turbine.  The wind speed’s frequency can be assessed in a particular location, they are fitted by a probable distribution function to the particular observed data.  Different wind distributions varies from different locations, hourly wind speeds at different locations are being monitored by the Rayleigh model, which basically means a continuous probability distribution which was named after Lord Rayleigh.

Electrical Generation

Using the power of electricity from a wind farm is usually fed through a network of electrical power transmissions.  This is done by connecting the individual turbines with a medium voltage power system and a series of communications networks.  The electrical current is then increased with a transformer to be able to connect to the high voltage transmitting system.  System operators supplies the wind farm owner with a code that indicates requirements  to be able to connect to the transmission grid which includes the power factor, the constancy of the frequency and the behavior of the wind turbines when experiencing system faults.

Now that we know that the speed of wind is not constant, a farm’s energy production is not as much as the sum of the nameplate rating being multiplied by the year’s total hours being used.  The ratio of this productivity in a whole year is called the capacity factor. This is the ratio of productivity in a year to this theoretical maximum.
