The consumption of natural fuels like petrol and diesel has increased manifold with the increased use of vehicles that run on these fuels. Since the beginning of industrialization we started consuming fossil fuels at an alarming rate. Coal, diesel and petrol are derived from fossil fuels that are going to exhaust one day if the current pace of consumption continues.

This makes us to find sustainable fuel for future needs. As of now there are two alternative fuels that could be used as alternatives for fossil fuels. Let us discuss about them in detail.

Bio-fuels
The energy of bio-fuels is derived from biological carbon fixation. These fuels can be derived from biomass conversion, solid biomass, liquid fuels etc. Based on the source from which they are derived there are a variety of bio-fuels. Two popular forms are bio-diesel (alternative to diesel) and bio-ethanol (alternative to petrol).

Bio-diesel is made by extracting and purifying plant seed oil to substitute regular diesel and made available to diesel engines. The most widely recognized bio-ethanol is the fermented extracts of corn or sugarcane. The natural ethanol thus extracted acts as alternative to petrol and can run on any petrol powered vehicles.

Pros and cons
Bio-fuels are inexhaustible energy sources, as they are extracted from plants produce. Automobile engines do not require major changes to run with bio-fuels. Since their origin is natural, they are considered sustainable and environment friendly. They help reduce dependency on import of crude petrol. They produce less emissions, thus, contribute to efforts for lowering global warming issues.

The possible disadvantages from bio-fuels are – there is an increased competition between bio-fuel crops and food crops, which is likely to result surge in food crop prices. Bio-fuel production encourages destruction of forests and other natural habitats for growing bio-fuel related crops, which will show devastative consequences on environment.

Hydrogen fuel
Hydrogen in its gaseous form can be used as fuel to run engines. Hydrogen is the most abundant element on the earth which is colorless, non-toxic and environment friendly. The source of hydrogen fuel is natural gas and water. Natural gas contributes 80% of hydrogen fuel and the rest comes from water resources through the process of hydrolysis.

Pros and cons
The production process of hydrogen fuel is safer and cleaner than petroleum production. Hydrogen fuel ensures future security in terms of fuel, economic stability and reduces the dependency on petrol and diesel. Hydrogen fuel produces zero emissions of pollutants which again contributes to the sustainable development of country.

The disadvantages of hydrogen fuel comes from its production cost. Process of making hydrogen fuel is expensive. Since development of hydrogen fueling infrastructure is still in early stages, it requires major changes in vehicle’s engine design and thus makes automobiles expensive.

Cloud computing allows users to “manage and reinforce data from online sources”. Users can retrieve and share data such as contacts, e-mails, documents, and even movies through their mobile devices or other PC’s. Examples for cloud-based services are G-mail and Google Docs.

Accessing a cloud service can be done off-site, through a third-party provider or via the Internet through a browser. It is beneficial and convenient for businesses that depend on particular software for running their applications. Instead of purchasing software’s in bulk, each user can access it through this method which will save the amount of expenditure on software’s by the business. So, we can say that cloud computing will change the way we organize and approach our data.

Through cloud computing technology users can create their personal clouds, or collections, of their data and documents. They can also synchronize with other devices such that they can access data where ever they want. Twitter and other RSS feed blogs have utilized cloud computing to allow users to access other users’ data. Now it can be a fairly new concept but it can be seen in near future.

In this cloud technology, security will move to “centralized trust” that is everything is managed by the cloud that is provided by the service provider and the users do not need to worry. And also centralization of data in a cloud is a key advantage for the users where anybody can use through a publicly accessible API, such as stock market behavior, clinical outcome data etc.

The future of cloud computing should be highly considered by businesses of any industry because the possibility of full adaptation of cloud computing by almost any industry is slowly starting to happen.
