Why are more and more homeowners turning their interest towards the thought of solar panels and often adding wind turbines as well?

In this time of economic uncertainty people are looking to become self-sufficient, people who have solar energy don’t worry about when the next blackout hits. Following or maybe first is saving money and then there is the wits that sits high with many and that is taking that step towards a green planet.

Electricity From the Wind

When the wind blows the blades spin the wind turbine, which in turn makes electricity. A small windmill won’t run the whole house but it can be hooked into the electric panel for the house as a power source so it uses less from the power companies.

The giant windmills seen along highways are referred to as “wind farms” for harvesting the wind. They are providing a new source for jobs and bringing looked-for power to our cities.

Small homemade windmills are being used on farms and backyards and a few roofs of homes in mostly rural areas. Placing a wind turbine or generator on the roof is not recommended due to weight-bearing factors. Height is vital for getting a steady wind current. Be prepared to build a tall sturdy tower for your wind turbines.

Likewise with the discovery of the photovoltaic effect, which is the production of electricity from the sun, solar panels have only gotten more efficient at using the sun’s power that it is a further source of energy to provide the home’s power wants. With enough solar panels to generate power to the home often there is an excess that the power company has to pay the homeowner for the electricity. Now that sounds nice.

Governments and Alternative Energy

Apparently, the satellites that orbit the earth operate solely from solar cells as well as buoys, lighthouses and warning signs on the highway. Surprisingly, many countries have been using solar energy for more than 50 years.

On Sept. 7, 2011, the Department of Energy issued a $340 million loan guarantee to SolarCity and U.S. Renewables Group Renewable Finance and Bank of America Merrill Lynch’s $1 billion SolarStrong project, which will place solar on the homes for service members living on base across all branches of the U.S. military.

Below the project, 160,000 homes on military bases will have solar systems below the SolarStrong project, which will likely be the largest residential project in the world.

Available and Affordable?

Does this mean that we are moving forwards to having solar panels on every roof in the U.S. and the world?

That will depend on the the ability of homeowners to afford the cost of professional installation which can run anywhere from $6,000 to $20,000 according to the home’s need and size.

An alternative is DIY method, buying online manuals with step by step video instructions for building your own solar panels and wind turbines. The money it costs plus the materials is a fraction of what professional installers are charging. Besides it is a fantastic project that sends a message to friends and family that this homeowner wants a green planet.

According to experts, a professionally installed solar system will last for 20 years or more and the Do It Yourself panels last about 6 to 8. With extra consideration given to caring the panels from the elements the homemade ones can last even longer.

This is a subject that continues to bring hope for a country so dependent on non-renewable sources like oil, coal and natural gas.

Here we have a renewable store, call it Infinite Energy, where the sun keeps on bright and the wind is still blowing over mountains and down through the valley floor.

Rising price of non-renewable energy sources, growing energy consumption especially from emerging countries, pro-wind regulatory environment for wind projects and increase in utility scale wind energy generation farms have place the world at 197 GW installed capacity at the end of 2010. In, 2010, 37.6 MW of wind turbines were installed; mounted with 70,579 blades, valuing market size of $6.8 billion.

Asia-Pacific is the fastest growing market and will grow by 19.3% CAGR during 2011 – 2016. By 2016, The wind rotor blade market in Asia-Pacific will be at $9.1 billion with annual installation of 93,243 blades. The growth of Asia-Pacific is attributed toChina, where market is growing in support of internal market drivers such as government support through various subsidies, rising turbine demand from existing and proposed wind farms, and inexpensive raw material availability. Recently,China has presence of all major blade manufacturers with their facilities in the region. Currently, the country has presence of more than 50 blade manufacturers and most of them are very small with product portfolio of 1 – 3 small size blades.

The blade size of 38 – 50 meter length has the largest market with global market share of 55% during 2010 and will grow to 62% in 2016. Glass fiber composites are the predominantly used materials in modern blades and approximately 0.15 million metric tons of glass fiber was utilized in blade manufacturing during 2010. Carbon fiber is upcoming material usually used in blades sizing more than 45 meters. In 2010, estimated 8,160 metric tons of carbon fiber was used for blade manufacturing; which will increase to as much as 2 million metric tons in 2016 with growth rate of 22.9% CAGR during 2011 – 2016.

Blade testing is very crucial with respect to blade’s reliability during its life cycle and thus makes a market for test facilities.Europeis the most mature market with number of test facilities available in the region. In past few years, blade manufacturing base has shifted from Europe to Asia-Pacific, especiallyChinabut Asia-Pacific has the lowest number of test facilities.

In recent times, the use of wind energy turbines has increased considerably. Wind turbines convert the energy of the wind into electrical energy. Here are the different components of a wind turbine.

Fan blades: The fan blades rotate when the wind passes through them. The blades are connected to the hub. They are typically made from frivolous materials.

Shaft: The hub is mounted on the shaft and it rotates with the rotating blades. If the wind speed is very quick brakes are applied to control the speed of rotation the shaft and the blades.

Transmission gearbox: The transmission gear is used to increase the speed of the shaft. On its own, the shaft is not quick enough to produce electricity.

Gearbox Output: The input is provided to large gear rotating slowly and output is obtained from the small gear, hence the speed of the output shaft increases.

Electricity from the generator: Electricity is generated with the help of the high speed output shaft, which is connected to the generator and it rotates inside it.

Wind turbines are used for both residential and commercial purposes. Small wind or residential wind turbines can be used to power appliances and lighting.

Electricity can also be stored in the battery and used when required. Wind turbines can also be built at home, if you the materials are available. This will cost much less than buying a new wind turbine from the market.

Wind turbines are also grouped together. This agreement is called a ‘wind farm’. Wind farms are used for commercial purposes and they are built in open areas where the wind blows steadily. The turbines are mounted on tall towers to maximize the energy output. The power generated by these farms can be used to fulfill the energy requirements of the local community.
