Facts About Biodiesel Prices

Biodiesel is a biofuel which is obtained from different renewable sources of energy such as animal fats and vegetable oils etc.  It is obtained through a chemical process from different naturally occurring (biological) components. Due to the shortage of conventional sources of energy like petroleum, natural gas and so on, and because of the harmful impact of these sources of energy on the environment of our planet, there has been an increase in the usage of biodiesel and the growth of biodiesel stations in the last few years. Biodiesel is a clean source of energy which is renewable and is easily obtainable compared to the conventional fuels like petroleum and diesel.

Studying Biodiesel Prices

Biodiesel can be used to run vehicles, produce heat and electricity, and in meeting the household energy needs of people. However, there has been a concern about the biodiesel prices as it is a popular belief that biodiesel is more expensive than the conventional fuels.

This is not entirely true! Even though biodiesel can be more expensive than petrol or diesel, when be purchase it from the manufacturers of bio fuels, it can be easily made at home for a much lower price. People can use different methods and technologies available which will allow them to manufacture this biofuel at home, with the help of used vegetable oils and other bi-products of cooking. Hence, biodiesel prices can be cheaper than other fuels that we use in our daily lives.

Factors Determining Biodiesel Prices

In most cases, the factors that determine the biodiesel fuel prices manufactured by different ‘clean energy’ companies are the cost of transportation and the cost of purchasing raw materials. In some places, the raw materials will be easily available while in other cases they may not be easily available.

Hence, people will need to transport the raw materials from other locations which will end up increasing the final cost. On the other hand, the companies which have easy to access to the raw materials and do not have to spend a lot of money in their transportation will be able to reduce their manufacturing cost. In turn, they will be able to reduce the final prices of the biodiesel they manufacture.

Taxes and Subsidies

In most of the states in the US, the biofuel manufacturers get a lot of subsidies from the federal government. Besides, they also get rebate on different taxes that other companies are needed to pay. For example, these companies get tax rebate on the federal excise tax. These subsidies and discounts in taxes help the companies in offering the bio fuel at a lower price.

One the other hand, people who use biodiesel to power their vehicles or meeting the energy requirements of their homes or offices also get tax discounts and subsidies from the government. Thus, it becomes easier for them to invest on biodiesel rather than investing on any conventional fuels.

Biodiesel prices are not too high most of the times and even if they are, people will be able to save a lot of money in the long run, by using biodiesel.

Rooftop Wind Turbine – Your Home Energy Resource

Fossil fuel is a fading solution when it comes to energy providers. The future will be dominated by renewable energy processing structures and oil or gasoline will be extinct because of the increase in world population and fossil fuel use. Using a rooftop wind turbine is a good way of starting the transformation process. Wind energy is very popular in many countries across the world, especially those with constant strong winds. Operating a rooftop wind turbine comes with incredible advantages that include low costs, efficient maintenance and silent energy processing.

Who Can Use a Rooftop Wind Turbine?

A rooftop wind generator solution is a great opportunity for industrial, commercial and domestic use. It is suitable in both urban and rural environments and can provide a constant and cheap alternative to all other energy sources. It does not pollute the environment regardless its use and it can be run by any person. In the last few years using a rooftop wind turbine as a main energy generator has become quite the trend all over the world. This type of technology has won many prizes and it is slowly catching up on solar and water power.

Think Green and Save Money by Doing So

Using a rooftop wind turbine comes with several strong points and almost no downsides. It does not matter if you live in the city or the country-side. A properly placed and maintained energy processor such as this will drastically lower carbon emissions and pollution levels will go down. Your electric bills will never be lower. Another great thing about this type of solution is the nice visual impact a wind turbine has on passing by individuals.

The Safest and Most Silent Solution on The Market

A normal system like such as Swift Wind Turbine is capable of generating less than 35Db of noise, no matter the wind conditions. To better understand the massive impact this type of approach can have on cities, know that those noise levels are lower than a whisper. Imagine if all cities would be powered by rooftop wind turbines. The world would be much more pleasant. The basic principle behind wind turbines uses a diffuser ring constructed around the propeller. This will deflect wind currents from the tip of the blades, making it as quite as a mouse.

A rooftop wind turbine comes with both electrical and mechanical safety mechanisms. All structures that use wind as their main energy sources have been tested and used under harsh wind conditions. Current technology is approved by all governments across the world and has already started to surpass all safety standards.

The Benefits of Having a Rooftop Wind Turbine

It is a cheap alternative to common energy sources and can save up to 1000 kg of CO2 every year. It is easy to mount and use. It is very silent and can produce somewhere around 2000Kwh if set in the right place. It lasts for more than 20 years and can save and bring you money through many grand opportunities and tax cuts.

Monocrystalline Solar Cells – Efficiency and Inventively

If you take your time and learn a few things about solar panels you will find that most of them are made out of monocrystalline solar cells. These structures are also known as crystalline silicon solar cells or just crystalline silicon and are commonly integrated with photovoltaic technology.

This apparently innovative engineering scheme goes back all the way to the 50′s. The first ever purpose of monocrystalline cells was to convert and conduct solar energy that will eventually be turned into electricity. The principle behind this whole thing is simple.

The sunlight interacts with a silicon semiconductor that helps absorb energy, permitting electrons to move freely. The monocrystalline cells are created in order to direct free electrons that are part of an electric field, towards circuits that use electricity to power appliances.

Polycrystalline vs. Monocrystalline Solar Cells?

The difference between the two is found within the manufacturing process. The polycrystalline cells are created by melting and pouring a silicon compound into a mold and the monocrystalline solar cells are cut into thin pieces from a larger crystal constructed for this exact purpose.  The single crystal cells have a blue color given by the uniformity of the cut. It is efficient and different from the various shades of blue that compose the polycrystalline modules. The cells are laminated by using tampered glass and plastic. The connection between them is mad with clear adhesive fixed on an aluminum frame.

The Efficiency of Solar Cells

Probably the most interesting and worth improving area regarding this type of technology is cell efficiency. Scientists have reached the conclusion that only ¼ or actual sunlight is processed and transformed into energy. The monocrystalline solar cells have achieved a 24% efficiency rate but only after years of research and experimentation. This massive loss of energy is explained as a consequence of the wide spectrum of sunlight wavelengths.

Looking Towards The Future

Very few know that this stage of monocrystalline solar cells research is the result of 50 years of hard work. The solar cell industry and technology are reaching their full potential after such a long period of time. The big breakthroughs over the last few years lead to massive decreases in prices and great increases in popularity. New mechanisms and systems are flooding the market and design and maintenance are becoming better every day.

What Benefits may Come with Monocrystalline Solar Cells

The use of such technology has its main advantage when it comes to saving money. Monocrystalline solar panels are the way of the future and will replace all other obsolete, rudimentary energy sources. This type of investment will last you a lifetime and spare you incredible amounts of money over the years. Investing in solar panels will make it worth your money and in 10 years you will be the proud owner of a device that paid for itself.  People are now more informed and up to date with news regarding solar cell research and try to make the most out of this incredible possibility.

The History of Algae Biofuel

If humans may be called the microcosm of the universe, algae can be considered as the microcosm of environment-friendly energy coming from existing biological sources – the new green biofuel. Wile global scale production of oil from algae still needs to overcome certain practical challenges, the homework on producing an eco-friendly form of biofuel from algae has been completed and various environmental-friendly fuel companies are looking forward to cash this immensely valuable natural source of energy that is barely visible to the general attention of our species.

The history of algae biofuel dates back to 1978 when the Aquatic Species Program (launched in the US) started research on energy production from high-lipid algae that were grown in ponds. Trying, at first, to get hydrogen from algal population, the program later focused on oil production, especially biodiesel. In the mid 90s, the research program came to an end and the publications from the program came out by early 2001. It concluded that the green biofuel from algae would only be economical if oil prices would double than the existing (1998) ones. Today, that limit has been far exceeded and hence the increased interest in algae biofuel for large-scale energy production.

Microalgae grow much more rapidly than land plants used for biofuel extraction. Their yield per unit area is up to 30 times greater than the most productive terrestrial plants. Also, algae can grow in diverse environments ranging from entirely aquatic to dry deserts with only saline groundwater reserves. Some of them have the quality of converting about 60% of their biomass into fuel. Obviously, algae stand as the most suited candidates for biofuel production. One of the most remarkable merits of algae biofuel production lies in the prospect of saving valuable terrestrial plants for other uses, particularly as food.

Today, algae biofuel stands at the forefront of green energy projects, including production of transport fuel, with a number of advantages over conventional forms of oil-extraction from non-algal sources. While algal biofuel may come in various forms like biodiesel, biobutanol, biogasoline, methane, and straight vegetable oil (SVO), currently the primary interest of fuel companies is the production of biodiesel from algae; so far, it appears the sole viable form of alternative transport fuel on a global scale.

Currently, algae biofuel production is emerging out of experimental stages in different parts of the world. In the Netherlands, Algaelink has developed a new way of extracting oil from wet algae through centrifugation of the algae paste. This development is more environment-friendly and will save more time and energy than previous methods of oil extraction from algae. At the same time, the UK-based independent company Carbon Trust – working toward low-carbon economy – has announced the world’s largest algal biofuel project that aims at developing the technology required for commercial extraction of biofuel from algae.

Since algae also remove a significant part of the carbon dioxide in the air, their use for biofuel production may be accompanied by a parallel growth of additional algal mass so as to make environmental amelioration a two-fold progress. The microcosm of algae as environment-cleaners is thus a green dream coming true within a lifetime.

Building Energy Efficient Homes

Energy efficient homes are a sparkling example of applying creative thinking for developing environmental friendly communities.

These houses are built by paying special attention to the construction details and various other elements of the house – all serving to cut down on the total energy consumption. This approach has a number of environment-friendly implications.

First, it helps conserve the energy budget of our ecological system.

Secondly, it prevents environmental damage that is caused by the emanations of pollutants associated with the consumption of some fuels. This in turn signifies better health. In addition, energy efficient houses save a good deal of money that is spent on paying for the energy required to run homes. It is important to mention that, according to studies on community development, the money thus saved becomes a source of generating wealth within the community.

Energy efficient homes vary in the number and style of elements employed in their construction and operation. Central to all of them are some basic features like:

•    Minimization of Heat Transfer
•    Proper Ventilation
•    Efficient Cooling and Heating Systems
•    Use of Energy Saving Appliances

Besides the advantages to environment and community development mentioned above, energy efficient houses have generally been found more comfortable, especially in terms of temperature stability and desirable levels of humidity. The passage of air in and out of the house is kept at an optimum level by specialized insulation techniques.

For lovers of quite environs (and who isn’t these days), energy efficient construction of houses also filter out most of the noise and keep the inside of the house peaceful. The main disadvantage of building these kinds of houses, at this point in time, is the high cost of construction. Also, the constructor needs to be experienced in handling such projects – something not yet very common. However, energy efficient houses do pay in terms of environmental amelioration and quality of domestic life, once they stand completed.

In the 21st century, the use of advanced computer technology promises cost-effective solutions to some heretofore costly procedures involved in the assessment of a particular area for constructing energy efficient houses.

This includes recording and processing of data relating the suitability of the location, mapping of the buildings, and limitations that need to be considered before squaring out for construction. For the green living motto of environmental friendly communities, energy efficient houses literally instantiate the (modified) adage of
