Wind Energy Converted to Free Solar Electricity



The secrets are made easy on how to build a homemade wind power turbine generator at home.
Having a home wind generator gives you the ability to create pollution free power. The major benefit is to lower your utility power bills by using the wind to power your home.
Everyone would like to stop paying for their electricity and know how to convert wind energy into usable FREE electricity by building your own homemade wind generator at home for less than $130.
Renewable energy is an alternative to using on the grid power and comes free from the sun and wind.
This renewable energy can be easily converted into household power to run your home appliances with homemade wind generators and solar panels. Design your home to run off the grid with this power generated from the sun and wind.
You Can Do the Same.
Many homeowners just want to make a difference in their lives and wanted to lower their electricity costs because power is getting too expensive and any savings would be a great help.
Commercial solar panels or power producing wind turbines are very expensive which only leaves the homeowner with the alternative to build their own.
Live Off the Grid with a Homemade Wind power Turbine Generator.
Before you decide to construct a homemade wind power generator, you need to determine if your area is windy enough and from what direction.
Wind direction and what happens to home made wind power generator when the wind direction changes is a relevant question because the wind generator blades need to capture this wind to spin the generator motor so as to produce the power hence the voltage and current needed to power the home.
Wind Direction short list that may help you.
1. Look at the trees for wind direction.
2. Use data from the U.S. Department of Energy available from the internet.
3. From local airports and weather stations.
Installation of a complete home energy system using solar power and wind power cost thousands of dollars and this may be out of the question for many to spend this amount of money on commercial brands.

Residential Wind Generators - Are They Right For Me?



Residential wind generator are becoming more accessible to a greater number of people than ever before. More people want to know, are they right for me?
There are many things to take into consideration when reviewing wind power, the first being the availability of wind in your area.Once you know if your average wind speed is favorable, the next step is to see if wind power generators are allowed under your zoning. You may need a building permit.
If you have neighbors close by you may want to talk to them about the aspect of a home wind power generator in the neighborhood. Some may be thrilled to see a proactive approach to green power. Others may have concerns about residential wind generators that need to be addressed.
The average wind speed in your area is a good starting point but there are many other variables that will affect the performance of a home wind power generator.The topography of your location greatly affects your wind availability. Even in a high average wind speed area, if you live in a valley or on the lee ward side of a bluff your wind power generators performance will be disappointing.
On the other hand someone in an area of low average wind speed could do quite well with residential wind generators if they are on a hilltop or the windblown side of a bluff or ridge. Some wind powered street lights claim startup speeds as low as four MPH.
The average wind speed in an area can vary greatly through the seasons. At our location in northwestern Illinois, our average wind speed in summer is class 2. In winter when all the crops are harvested and the leaves are off the trees we often reach class 4. Light wind residential wind generators should do quite well in our area.
Because of all the variables involved, and the expense of the installation, site surveys are required to more accurately assess the capabilities for residential wind generators at a given site. This is the only way to accurately gauge the size of wind power generators needed.

The Application of Hybrid Photovoltaic-Wind Power Generation



Wind Solar Power System is the source of all the energy on earthWind energy is another form of expression in the Earth's surface. Wind and solar energy have low energy density, the stability is weaknesses, and they are influence by geographical distribution, seasonal changes, day and night alternation. However, Solar and wind energy have Complementary in time and geographical. And the most sunlight during the day, thewind less, the evening sun, the light is very weak, but the surface’ temperature of earth has changed and wind to strengthen large. In summer, Sunlight is strength and wind is small. In winter, sunlight is weak and wind is strength. Stable is reliable solar power generation, but it has higher costs now. And wind power costs are lower, but random, and reliable power supply is poor. Day and night achieve power generation resources in the conditions of the suitable weather, wind / photovoltaic generating system can be complementary to each other to improve the continuity of electricity supply systems, stability and reliability if we can get them together. Therefore, the wind / PV hybrid generating system is the best resources of independent power system, in many areas has been widely used. Solar photovoltaic systems have many factors to effect. the complexity of the design not only to achieve both long-term reliability to meet the needs of the load, but also makes the minimum system configuration capacity, investment at least, must be carried out to optimize the system design, wind power generation system is also true . But the wind / optical hybrid generating system to the characteristics of two different power generation systems by combining their respective strengths in order to achieve the best match, which more than two separate power system design more difficult and complicated. A lot of wind / light power generation system while so-called optimized design, in fact, these two do not really complement each other power generation systems. Along with the production and living standards are improved, the world's energy consumption growth. Study shows that, 1965’s energies were increased almost 6 times than 1900. The past 40 50 years, a large portion of energy consumption come from fossil fuels. Many times the energy crisis led to the recognition that mineral resources are limited, the world's oil resources can only be maintained for several decades, people have gradually concern by shifting the focus to new energy development and utilization up. Expected the next century, new energy will be more important position of energy in the world. It was the atomic energy and solar energy can be referred to as the 21st century source.

Energy is a human life, one of the five elements that is the national economic and social development of strategic materials. New and renewable sources of energy mean that mass-energy, wind energy, solar energy, small hydropower, ocean energy, geothermal energy, hydrogen energy and other energy resources except to conventional energy sources other than hydropower and large-scale biological. At present, new sources and renewable sources of energy mainly in the form of non-commodity energy for the general provision of energy supply in rural areas, but with the social and economic development of new and renewable sources of energy is also steadily to change the direction of the commercialization of energy. Solar and wind energy applications is the relatively wide range of two renewable energy sources. Solar and wind energy have few advantages than other conventional energy sources to use. The interior of Solar releasing a huge light and heat due to nuclear fusion of hydrogen thermo nuclear reaction, which is the source of solar energy. Hydrogen production capacity in the area of nuclear fusion, hydrogen burning time of nuclear stability can be more than 60 million years. This means that the sun can be used indefinitely as now at least 60 million years., especially that conventional energy sources are less than before, it is extremely attractive to more people. Injection of energy the sun, the earth is only one ten thousandth 20, and the rest are lost to space, went to BU.The Earth's surface are entitled to receive 7.034×1024 Joule of energy for one year, which is equivalent to 200 trillion tons of coal combustion issued by the tremendous heat. According to the calculation of M.R.Gustavson, solar flux between the earth and the sun is 1400 W / m2, and the Earth's surface, the energy gained per second for the 350 W / m2, converted to electricity for one year equivalent to about 1.58×1018 degrees. Wind energy is a transformed form of Solar, which is estimated by M.R.Gustavson, boundary layer winds in the global total energy of 1.3×1015 watts, the year of about 1.14×1016 Kilowatt-hour of energy.

At present, this is equivalent the annual world energy by burning about 3000 times. Fossil fuels, coal and oil resources are uneven geographical, and industry caused by the uneven distribution of coal and oil transport uneven. Even it can be powered by electricity, but a number of mountains, islands, grasslands and high altitude, such as power grids are not easily accessible place, make full use of the advantages of energy weather will bring convenience. Although the distribution of solar and Small wind generator energy also has some limitations, but with the fossil energy, hydropower and geothermal energy, such as the comparison may be held to be a broader distribution of energy. Resources such as the world's oil distribution in the face of the earth do not Uniform, the world's proven oil reserves, only in the Middle East on the world's total reserves of 57%, and some consumer State-owned oil more oil reserves and output are relatively more, and some even do not produce oil. Coal carbon is also very uneven distribution of resources, the vast majority of the world's coal resources are embedded in the region for more than 300N, The former soviet union, the united States and china account coal for about 90% in the world.
