Whisper Wind Turbines

March 20th, 2010

The energy sector is greatly responsible for climate change and atmospheric pollution. Wind is a clean and environment friendly source of energy that produces electricity. Its renewable character and the fact that it does not pollute during its operational phase makes it one of the best promising energy systems in reducing environmental problems at global and local levels. However, wind energy, may cause impacts on the environment which should be analyzed and mitigated.

Whisper a name with more than 10 years of knowledge in the field, has been re-engineered and started under the Southwest Wind power family of wind turbines. The Whisper has an all-new appearance having a cast aluminum frame and smooth, quiet operation of the patented “angle-governor” furling design.

Whisper 100

Whisper 100 formerly known as Whisper H40, has been updated with new features and added flexibility for renewable energy system. It provides reliable energy for remote homes, telecommunications sites and rural applications in moderate to extreme environments. Dependable operation by thousands of customers makes Whisper 100 the top selling small wind turbine in its class. The Whisper 100, have 7 ft. (2.1m) rotor diameter and 40 sq. ft. swept area, which makes it rugged enough for extreme environments.

The Whisper 200 also includes a permanent magnet alternator powered with an advanced airfoil, as a result capturing the most energy in its class as compared to other competitive wind turbines. The Whisper will deliver 6.3 KWH per day. The Whisper 200 produces more noise than its Whisper100, but it does produce almost twice the power. The Whisper200 can be installed in just a few hours with no welding, no concrete or cranes.

Whisper 500 formerly H175

Formerly the Whisper 175, the Whisper 500 has a 14-foot (4.26m) rotor diameter providing 175 sq. ft. of swept area. The H500 has been redesigned, including a stronger, larger yaw shaft, new blade stabilizer straps and a third spindle bearing for increased reliability.

The Whisper 500 have a handmade fiberglass and foam core blade used for smooth, high efficiency operation and low wind start-up. It also includes the patented “angle governor” design for quiet operation in high winds, which is an ANGLE-FURL™, an incredibly effective, Whisper quiet, method of protecting the Whisper 500 in high winds and helps in maintaining the maximum output in all winds. The Whisper 500 is an outstanding machine for village power projects, farms, ranches, back-up power and remote homes, and off grid living with large energy demands. This 3000- watt rated turbine will deliver in excess of 500 KWH per month assuming a 12 mph (5.4 m/s) wind.

The Whisper wind turbine towers involve no welding however the largest towers need concrete. These are available in different heights like 24ft, 30ft, 50ft, 65ft and 80ft. All the installations can be done efficiently on the ground. The Whisper tower kits contain anchors, pope materials and power wires.

Whisper Controller and Digital Display

The Whisper 100, Whisper200, Whisper 500 Whisper 100 comes with the new Controller that presents greater reliability and superior control for battery charging. Its compact cabinet design features effortlessly settable voltage regulation points; load dump and load dump isolation from the battery.

Whisper controller protects both wind turbine and battery. It can be installed in minutes and it fits easily inside your battery room. You can add the optional LCD display and you will instantly receive real time data on the performance of your Whisper. The display can be mounted on the controller or up to 1000 feet away, so you can monitor performance in the comfort of your home. You can even add an anemometer to the controller so you can measure wind speed, and compare it to the output from your Whisper.

Facts

  1. Offshore wind power plants can deliver seven times the energy as land-based plants.
  2. There are three British offshore wind farms having a combined capacity of 210 MW.
  3. Wind energy can provide new sources of income to some rural areas having favorable climate conditions.
  4. Wind energy use has been growing movement in many countries, mainly in Europe.
  5. Wind energy can be shortly the cheapest way to produce energy on the large scale, particularly in areas with suitable climate conditions.
  6. Wind energy assures high working reliability, no fuel costs and no pollution.
  7. In recent years wind energy has provided for over 20% of the power consumption of Denmark, providing energy for a large number of homes and businesses throughout the country each year.[#1]
  8. The National Renewable Energy Labs stated that the Whisper 100 was one of the quietest wind turbines ever tested.[#2]
  9. According to the experts, in the United States alone if the 10 windiest states were to fully utilize their available wind sources the energy produced could compensate the entire coal-based power production facilities presently being used and substitute them entirely.[#1]
  10. If properly developed, wind power could successfully reduce carbon emissions in the US by at least one third every year and help realize a global carbon dioxide reduction of 4% yearly.[#1]
  11. In order to replace all energy consumption needs of the world with wind power production about 13% of all land will need to be developed for wind energy purposes, assuming the placement of six large wind power generators per square kilometer in certain area 80 meters above sea level in order to maximize wind energy potential. This can of course be reduced if we were to rely upon offshore wind energy production facilities as well as onshore ones.[#1]
  12. The large commercial wind turbines can be 500 feet high, and generate electricity in a 700 kW to 2.5 MW range. The farm or large yard turbine towers run about 30 to 50 feet in height, and can generate about 10 kW power. Rooftop models lack the height needed to get up into the best wind currents, and they need to be smaller all around to fit in with the overall look of any residence. Obviously they would produce far less energy, but enough to power lighting or small appliances.[#3]
  13. Top three nations now producing wind power are Germany, Spain, and the United States. Even in the forward looking US, the power produced is only less than a half of one percent of all electricity produced (2005). And, only half the states even have wind farms. Colorado is one of the leaders in renewable resource energy. The wind mill giant company based in Denmark, Vestas, has recently chosen to locate a new manufacturing plant, with about 1350 new jobs, just outside of Denver, in Colorado.[#3]

Alternative Energy ETF

March 12th, 2010

An alternative energy ETF invests in companies which are involved in alternative energy research and production. An alternative energy ETF holds a number of stocks of companies that generate energy from environment friendly resources. Exchange Traded Funds is as compelling an investment theme as you’ll ever come across. These Alternative Energy ETFs are created and marketed just like any other ETF. The only difference is the underlying securities.

As alternative energy ETF is a green investment. With global energy demand growing sharply, oil prices at record highs, climate change concerns growing, and new technologies allowing more proficient power extraction from natural resources, the case has never been better for investing in alternative energy companies that will assist us conquer our oil and carbon-emission addictions. With more and more companies focusing on alternative energy research, the portfolio of these ETFs is becoming increasingly convincing.

Alternative energy research is in the public interest due to two reasons:

1. Depleting natural resources
2. High demand of environmental friendly products

Many companies have by now launched their eco-friendly products in the market and the rest are catching up due to the growing demand for such products. This has opened up new opportunities for investments and alternative energy ETFs are smoothing the progress of their funding and profits for investors too.

Before you buy or sell any investment product you want to be familiar with all the limitations of the asset. Understanding the benefits of ETFs will assist you utilize the right investment strategy when including exchange traded funds in your portfolio. It is equally important to understand the disadvantages of ETFs.

Advantages of Alternative Energy ETFs:

1.Alternative Energy ETFs is a green investment.
2.ETFs are tax-friendly investment. Capital gains taxes are usually lower for ETFs than usual mutual funds due to the structure of each trade.
3.ETFs perform like indexes and pursue certain market sectors. But, not like an index, you can buy an ETF with one single transaction.
4.As there is single transaction per trade, commissions are lower on an ETF as compared to an index, which involves many stocks and multiple trades. Moreover unlike regular mutual funds, there are no load fees and managing fees tend to be lower for ETFs.
5.Alternative energy ETFs are narrower as compared to other ETFs. As the requirement for alternative energy is high, a narrow investment brings in more profits than a diversified one.
6.Alternative energy ETFs is the precise way to diversify your portfolio. The high volatility and demand joined with the prospects make these ETFs the perfect hedging funds.
7.Alternative energy ETFs are best for short term traders since they are very volatile and less risky.
8.Alternative energy ETFs are very flexible, like equity, ETFs trade throughout market hours. ETFs can be sold short or on margin, and prices are continuously updated during the trading day.
9.With most ETFs, dividends are straight away reinvested back into the fund. In the case of traditional funds, the time frames may differ.

Investing in alternative energy ETFs is a profitable and a responsible investment. But, one should identify that many companies invest only a small portion of their resources in alternative energy. Hence, lot of caution must be exercised while investing in these ETFs. The underlying securities must always be checked.

Disadvantages of Alternative Energy ETFs:

1.Alternative energy ETFs has a higher expense ratio. Their higher expense ratio than usual indices makes them an expensive fund to spend in.
2.Although the U.S. has an excess of ETF products, some countries only have a few ETFs in which to invest. Moreover those regions which offer market ETFs, generally only include large-cap products leaving a lack of normal and small-sized funds.
3.In spite of many benefits to include ETFs in your portfolio, but it is very important to know that they are not the perfect investment for every situation. ETFs must be evaluated on a case-by-case basis for every investing strategy. You should understand all the risks involved with ETFs before you get started.
4.As Alternative energy ETFs tend to be narrowly focused, the lack of diversification makes them prone to huge losses.
5.The high volatility of the ETFs, obsessed by rumors and emotions, can de-motivate traders from investing long term.
6.A number of ETFs are not as actively traded as others. It may be a sector associated issue or even a regional issue. When such situation arises, it may be more useful to invest in managed fund where activity is higher.

Facts:

1.Many green technologies are becoming economically viable. For example, through the development of less expensive materials and improved production and installation methods, researchers aim to make solar cells cost-competitive with traditional electricity by 2015.[#1]

2.China has set a goal of creating 30 gigawatts of renewable energy capacity by 2020, up from 1.3 gigawatts now. [#2]

3.In 2007, for example, $18.9 billion of new money was raised in the public markets by clean energy companies — up 80% from 2006. And more than $6 billion was raised through the initial public offering of a single company.[#3]

4.Money is required to fund research and development of green technology. Money is needed to build the infrastructure that carries clean water to families and fields. In the U.S., it’s estimated that $662 billion is needed for water infrastructure from 2000 to 2019.[#4]

5.As developing nations industrialize, pollution has come to the fore. The World Bank estimates that between 2001 and 2020, nearly 600,000 Chinese a year will die prematurely due to air pollution.[#2]

6.The Chinese government estimates nearly one-third of the country’s rivers are too dirty for agricultural or industrial use.1 In addition to the human toll, the economic toll is huge — pollution and its related health problems cost China $54 billion a year.[#2]

7.Of the 11 industry segments that make up the cleantech investment category, the top five categories by total financings were solar, bio fuels, transportation, wind and smart grid.[#5]

8.Cleantech investments in North America, Europe, China and India reached $8.4 billion in 2008, up from $6.1 billion in 2007.[#5]

9.Transportation is the fastest growing source of greenhouse gas emissions in the U.S., accounting for 47% of the net increase in total U.S. emissions since 1990.[#6]

10.Eighty-six percent of the U.S.’s primary energy — the natural resources we harness for power — comes from carbon-emitting fossil fuels.[#7]

Solar light panel

March 8th, 2010

Solar energy is the cleanest and inexhaustible of all known energy sources. Solar energy is nothing but the light, heat and other radiation that is emitted from the sun. Solar radiation holds huge amounts of energy and is responsible for almost all the natural processes on earth.

Solar Light panels are completely free standing. Simply fit the light components collectively, press the spike into the ground or screw on to the wall mounting, it really is that simple! Power is provided by solar panels, located tactfully on the head of the lights.

During the day the lights charge up with free solar energy via the solar panels collecting power from both sunlight and daylight. The energy is stored in long-life NiCad batteries (supplied) integrated into the lamp body. Often, these lights are designed to turn on automatically at end of the day, providing an enhancing effect through-out the night, and then charge up again during the day. All weather design ensures that Solar Lights are not affected by unfavorable weather conditions ensuring years of pleasure.

Science behind the working of Solar Light Panels:

The system operates just like a bank account. Withdrawals from the battery to power the light, source must be compensated for by adequate deposits of energy from the solar panels. Provided that the system is designed so deposits exceed withdrawals on an average daily basis, the battery remains charged and light source is consistently powered.

Features of our Solar Light Panels:

1.Automatic sunset sensors operate light at evening.
2.Strong design ideal for year round outdoor use.
3.Solid state Light Emitting Diodes give 20,000 hrs life.
4.These are the very economical lighting system.
5.Sun is a direct source of energy for the solar panel.
6.The battery is recharged during the day by direct-current (DC) electricity produced by the solar panel.
7.The light source is powered by the battery each night.
8.The electronic controls are used between the battery, light source and solar panels to protect the battery from overcharge discharge, and to control the timing and operation of the light.

Why to opt Solar Lights:

•Solar Lights are the very economical. As the cost of energy is always on the rise, every person is looking for more affordable options. Solar light panels are not only affordable but can be operated from natural sunlight, which is available for free for you. The natural sunlight provides the power for solar lights to work. They do not require electricity or gas. As this power is generated without using any external energy source, your energy bills will be much lower. Solar lights are the most reasonably priced type of outdoor lighting that you can find anywhere.

•No trenching, no metering, no wiring.

•A most important consideration is that these lights will not use up other energy resources. As electrical power and gas power are not needed, using solar light means that you are going green and you are doing your part to make sure that these resources are not depleted.

•These lights will get just the right amount of power to make them completely effective. These lights are not overly bright or very dim light that is essentially useless, but are completely effective.

•Solar light panels are easy to install. You will not require to waste money hiring a professional to do it. You can have your lights suitably installed and in great working condition in no time at all.

•Solar lights also look great. There are several different styles available that it will be effortless to find the style best suited to your needs. Whether you are looking for something modest, stylish, to blend in with the natural environment or to give a bold contrast, there is one accessible for you.

•Solar light panels are both attractive and practical. These lights make your yard, streets, driveway, and walkway lit with just the right amount of lighting.

As you can see, there are plenty of reasons why you should consider adding solar yard lights to your home. They are the best choice for outdoor lighting available today. Let’s try to get out of this ferocious treadmill of paying hard earned money to the companies for their electricity. Make use of solar light panels and reduce your bill…….

Facts:

1.NASA estimated that the Sun gives or irradiates the earth 174 Petawatts (Pw) of solar energy every day. Out of this roughly 30% of energy is reflected back to space, and another major share is absorbed by our atmosphere. Even if we get only 10% of this energy which is about 17.4 Pw per day, it is still more than the whole daily energy requirement worldwide. [#1]
2.Solar light panels help in deterring crime and by using these lights, you can augment the visibility of your place thus augmenting the safety of people who walks along the pathway while taking the benefit of reduced electric bills.[#4]
3.Do you know out of total solar radiation that falls on our solar panel how much energy does our Solar cell absorb? Sorry to say that our simple solar panel can absorb only about 14 % or less.
4.Solar energy is sustainable, clean and green energy.
5.The batteries incorporated on Solar Lights panels are recharged during the day. The battery used is so efficient that it can hold power all through the whole night which is usually for 12 hours.[#4]
6.Solar energy with the help of developing technologies play an important role in reducing greenhouse gasses and helps in stimulating the economy.
7.Solar Energy is measured in kilowatt-hour. 1 kilowatt = 1000 watts.
8.1-kilowatt home solar system consists of about 10-12 solar panels and requires about 100 square feet of installation area. [#2]
9.Solar thermal technology can also create electricity by creating steam to power generators.
10.In 1990, a solar powered airplane flew across the U.S.[#2]

11.The “solar panel” accounts for between 40-50% of the total cost of an installed solar energy system. [#2]

12.During the 15th century, Leonardo da Vinci already had plans for solar concentrators in his notebooks.
13.In just one hour, the earth receives more energy from the sun than the entire world uses during a whole year.[#3]

14.Solar energy can produce lighting for indoor or outdoor use. It can be used to heat swimming pools, power cars, and small appliances. You can even cook food with solar energy.
15.According to a global price survey, solar energy prices have declined an average of 4% per year for the past 10 to 15 years.
16.A 1-kilowatt home solar system will prevent approximately 170 lbs. of coal from being burned, 300 lbs of CO2 from being released into the atmosphere and 105 gallons of water from being consumed each month! [#2]
