In a rather “environmentally concerned” approach to cut down on the carbon emission from flights, Lufthansa airlines has announced that they will start commercial biofuel flights daily between Hamburg and Frankfurt in a six-month trial from April 2011. The move to operate an aircraft engine with biofuel over a long stretch of six months, is first of its kind in the world.

Energy security issues, hike in petrol prices and climate change from greenhouse gases emitted by airplanes have been troubling the airline industry for quite some time. Virgin Atlantic Airlines, British Airways and Continental Airline have have already tested on biofuel flights in the last two years. However, environmentalists have been constantly warning that production of biofuels can also have adverse effects on environment.

Utilizing biofuel in flight operations can save around 1,500 tonnes (15,00,000 kg) of Carbon dioxide emissions. However, as the airline industry worldwide is calling for an alternative source of energy, there’s a need to check for the sustainability of biofuels against fossil fuels and their effect on aircraft’s engine over a longer term. Plus, environmental concerns are another big issue related to production of biofuels.

According to a report by UN Food and Agricultural Organisation, biofuel plantations are destroying ecosystem of various regions in the world. Palm oil plantations set up for biofuel production in Indonesia and Malaysia, have led to deforestation resulting in more emission of greenhouse gases as the worst consequence.

In such a situation, a sustainable and environment-friendly way to produce biofuels is the need of the hour.

Biofuels are when we use organic matter as fuel by converting it into power for use. By producing biofuels, this is an alternative energy source as we depend on fossil fuels. The ethanol products include under its aegis, derivatives of plants like sugar cane, and also corn and vegetable oils, all part of the biofuels umbrella. Not all of them are designed for use as gasoline, although the International Energy Agency (IEA) say that by 2025, 10 % of the world’s gasoline could be made up of ethanol products, and by 2030, it could be up to as much as 30%. At the moment, the percentage stands at just 2%.

A lot of research is going into biofuels, and it will be some time before we can refine them to make them more economic and practical enough to use. Oregon State University have done a study to prove this. Biofuels have not yet been developed which are as energy efficient as petroleum which makes up our gasoline. To put it simply, energy efficiency is how we measure the usable energy that is derived from the input energy by a certain amount. (Up till now we have not come up with any product where the output energy exceeded that of what was input). What is most important is the end product energy that has been converted and its usefulness for our society’s needs, the effort involved is what we put into the input energy so as to produce which is the end-product. A study by the OSU found that ethanol which is corn-derived was only 20% energy efficient (compared to gasoline that is 75% energy efficient and made from petroleum). Biodiesel fuel had a recorded energy efficiency of 69%. Out of the study came one positive thing: higher than nuclear energy which is effectively efficient, was cellulose-derived ethanol charted as 85% efficient.

The New York Exchange has marked a change in oil for the future, with analysts from many countries having predicted surges in the availability of biofuels, which would offset oil prices, seeing crude oil drop to prices of about per barrel on the international market. On the Chicago Stock Exchange there is more investment activity in future markets on grain, making a “steal” on the oil futures of New York, with investors expecting much better profitability from biofuels to come. By 2030, a consensus of analysts have predicted that biofuels will account for 7% of transportation for all round the world. Demand for and diesel and gasoline will slowly fall dramatically according to one energy market analyst, as government supports the use of the more eco-friendly biofuels and subsidise the manufactures of this fuel.

Many nations support the use of biofuels and its production in developement.

Brazil is the biggest in the production of ethanols that are derived from sugars. Approximately three and a half billion gallons of ethanol is produced in a year.

The greatest oil user is the United States, who already come second behind the largest producer, Brazil, in biofuels.

The European Union now have an excess of four million (British) tonnes in biodiesel production capacity, of which 80% is derived from rapeseed oil. The remaining 20% of the EU’s biodiesel fuels is marginally from palm oil and the rest comprised of soybean oil.

Just like solar energy, wind energy is another environment-friendly and economical energy source. With almost 40% of wind energy sources of Europe in the United Kingdom, there is immense potential to use wind energy as a source of energy.

Generating power through wind is not only efficient but also renewable like solar energy. The only downside is that a tall, moderately sized generator can be a sore eye and spoil the visual landscape, leading to murmurs of disapproval among neighbours. Think about this before you go ahead and think about how to generate wind energy in your area. However, if you do not live in a very populated area and your neighbors consent to your wind energy project, there could be nothing more beneficial to harness the potential of such a natural and renewable resource called wind.

Getting Help in the Start

If you are wondering how to generate wind energy, the British Wind Energy Association or BWEA is a good professional source of services and information for initiating projects related to wind energy. This professional body continuously organizes and manages several initiatives to propagate the use of wind as a source of energy across the country and its residences. It has information on local suppliers of wind systems and information on grants and permissions.

The ‘Energy Saving Trust’ which is backed by the government also provides provide advice on several issues for both companies and individuals and companies desiring to install wind generators on a small scale.

Other Practicalities like Cost and Savings

The cost of wind generators should fall in the range of 3000 pounds -15000 pounds for each kilowatt. This is as competitive as solar and actually slightly cheap when compared to the high output it generates. It is also expected to generate higher output in a year compared to its output in the previous year. Your wind generator should break even in about five years and the way the prices of normal energy sources are increasing, the returns of a wind generator will surely increase over a period of time.

How to Position Your Turbine

It is best to place the turbine high if you want to get the most of the wind strength without any obstructions. Also make sure to measure the wind strength in your locality so that you can place the turbine facing the direction where the wind is prevailing. To measure the wind strength, you can either buy or hire an anemometer. You can also get the person installing your wind generator to do that.

Battery or Grid?

A battery can be connected to wind generators of small scale to provide electricity to your house. The other option is to connect the wind generator to the National Grid. The decision to do the former or the latter depends totally on the circumstance. As such there is no major difference except that it will affect the direction of your energy. If you happen to stay in an area that is remote with no access to the National Grid, energy should then be directed to the battery which in turn will be connected to your residence’s mains. If you can easily access the National Grid, get the generator connected to the grid. By connecting to the grid not only will you be benefited from power savings by not using the supply of electricity from the grid, you will also be able to sell surplus electricity to the grid.

As people are waiting for “them” to make biofuel available as a source of energy there are many of us who have been using forest biofuel to heat our homes for generations. This biofuel is sold on the free market without government subsidies or a need for more research and development.

Wood can be made into many biofuel products like methane, alcohol, or diesel and it can be burned directly to power electric generators to produce electricity. All of these are expensive and energy intensive. After refining wood into these biofuels the cost and energy used has not made wood biofuel a viable source of energy. The exception to that is burning wood to generate electricity which has experienced some commercial success.

What people often overlook is a form of wood biofuel that requires very little or no processing and that is wood as a heating fuel. While people are waiting for biofuel they are still using fossil fuels to heat their homes when they could switch today to an economically proven biofuel heat source which is to burn wood.

Since there is little or no processing required, direct heating with wood is more efficient than turning wood into another fuel such as diesel or electricity. The raw material is directly converted to the desired product which is heat.

The most basic form of wood biofuel is simple firewood for wood stoves and fireplaces. This is a very desirable form of energy for many homes but it’s not for everyone. Burning firewood does have some disadvantages such as wood handling, it can be messy and can produce smoke. Although modern wood stoves have come a long way in reducing emissions and efficiency. Modern wood stoves can burn with no visible smoke. Burning firewood is not as convenient as other heat sources since you have to continually feed fuel into the fire.

The alternative to fireplaces and firewood stoves is wood pellet stoves. Wood pellets require more processing but pellet stoves are more efficient than firewood stoves so it makes up for the difference. A pellet stove combines the use of renewable biofuel with the convenience of traditional electric, gas or oil heating systems.

Pellet stoves have automatic fuel feeding systems and are thermostatically controlled. Wood pellets are available today and have been proven as a heat source that is competitive and can even cost less than fossil fuels.

Both firewood and wood pellets are available as a practical source of forest biofuel that you can start using today. Which one you choose depends on your situation and preferences.

Alternative Energy sources such as Biofuel, Biodiesel, and Green Oil are rapidly becoming big business as ethical investments become lucrative.

We are using more fossil fuel oil than we are finding. Though experts disagree about the time scale, most agree that the rate at which we are consuming traditional oil is now greater than the rate at which new reserves are being found, we have already entered the depletion phase and are on a downhill slope of terminal decline. In short, crude oil is running out.

What are our alternatives?

Biofuels.  Thanks to the Gulf of Mexico fiasco, many people are totally reconsidering the use of fossil fuels for energy and are opting for a cleaner, less harmfull alternative fuel like Jatropha or Millettia biofuels but what are they?

Jatropha and Millettia what?

Jatropha and Millettia are two hardy plants that can grow in harsh desert conditions, needing little water and care. Biofuels from Jatropha or Millettia are formed by crushing the seeds of the plant and extracting the oil.  The waste is biodegradable and can be used for farming.

What makes them so good?

Bio fuels are better for the planet and humanity for a variety of reasons:

Can be made in a matter of days as opposed to fossil fuels which take millions of years to build
Are safer compared to fossil fuels which produce pollution and harm emissions
Unlike fossil fuels, are a renewable source of energy which means that they can continually produce more energy

Both the Jatropha and the Millettia plant take about 3-4 years until they produce a significant amount of seeds to turn into “green oil”.  Once the plants are established however, it can live up to 20 years or more.
No machines are needed to take care of the plants or to harvest.
It is a renewable source of energy, producing year after year.
Nitrogen rich fetiliser, medicines and rubber can be made from the waste produce.

Why should we invest in this?

Fossil fuels will only go up in prices and are harmful to the environment so we need to take a stand and start investing in this new emerging technology.  World economy needs to start investing in the future of the planet and the human race.
