Environmentally friendly alternatives to oil including algae method essay

Precious Metals Population is not of concern if there are enough resources to go around. Important resources like water of suitable quality for growing crops, drinking, cooking, and cleanliness, fertile soil for growing food and trees, and fuel for warmth and cooking. Depletion of important resources leads to poverty, disease, malnutrion and often death.

Messenger Algal biofuels are in trouble.

Carrying Capacity and Ecological Footprints

This alternative fuel source could help reduce overall carbon emissions without taking land from food production, like many crop-based biofuels do. But several major companies including Shell and ExxonMobil are seemingly abandoning their investments in this environmentally friendly fuel.

So why has this promising technology failed to deliver, and what could be done to save it? Algae are photosynthetic organisms related to plants that grow in water and produce energy from carbon dioxide and sunlight.

Single-celled microalgae can be used to produce large amounts of fat, which can be converted into biodiesel, the most common form of biofuel.

There are many possible ingredients for making biofuels, from corn to used cooking oil. But algae are particularly interesting because they can be grown rapidly and produce large amounts of fuel relative to the resources used to grow them high productivity.

Watch it. Love it. Buy it!

In the last decade or so, vast amounts of money have been invested in the development of algae for biofuel production. This made sense because, ten years ago, there was a need to find alternatives to fossil fuels due to the high oil price and the increasing recognition that carbon emissions were causing climate change.

This is a series of articles and updates related to the effort by the residents of Fort Lauderdale and surrounding communities to rescue their shrinking beach from the ravages of tidal erosion. Traditional ethanol and oil Preview. Biofuel. 4 This is because of the general consensus that we need environmentally friendly fuel alternatives. It is because of this new found popularity that amazing developments are meing made every day. come up with a concluded plan for a possible replacement of fossil fuels. It is called. Algae is a micro-organism, that can produce its own food through the process of photosynthesis. Disclaimer: This essay has been submitted by a student. This is not an example of the work written by our professional essay writers. In addition to that algae constitutes of a broad wide profile of fatty acids including Omega 3 and Omega 6.

Algal biofuels were touted as the answer to these twin problems, and huge investment followed. Companies making algal biofuels struggled to retain their high productivity at a larger scale and found predators often contaminated their farms.

Building the ponds in which to grow the algae and providing enough light and nutrients for them to grow proved too expensiveand to make matters worse the oil price has plummeted. In fact, algae are like microscopic factories producing all sorts of useful compounds that can be used to make an amazingly diverse range of products.

For example, algae can produce large amounts of omega-3 fatty acids, an important dietary supplement. This means it could be a sustainable, vegetarian source of omega-3, which is otherwise only available from eating fish or unappetising cod liver tablets. More generally, algae are excellent sources of vitamins, minerals and proteins, with species such as Chlorella and Spirulina commonly being consumed for their health benefits.

Another useful product that can be made from algae is bioplastic. Regular plastic is a product of fossil fuels and takes an extremely long time to break down, which makes it very environmentally unfriendly.

Bioplastic from algae can be produced with low carbon emissions, or even in a way that absorbs emissions. Their use could help prevent the build up of plastic in the environment. The diversity of these products may be the key to finally developing algal biofuels. Many are high-value chemicals, selling for a much higher price than biofuels.

So by combining them with biodiesel production, we could subsidise the price of the fuel and offset the high costs of algal cultivation. We already know that oil refineries produce plastics, fibres and lubricants as well as fuels. Now we are hoping to develop algal biorefineries in exactly the same way.

Could health supplements like this be the solution to our biofuel problems? These are widely available from power plants, factories and water treatment plants and so could reduce some of the costs of growing algae.The table below presents an abbreviated geologic time scale, with times and events germane to this essay.
