Although not widely used today as a transportation fuel‚ government and industry research and development are working toward the goal of clean‚ economical‚ and safe hydrogen production and hydrogen fuel cell vehicles.

Can Petroleum Be Replaced? Today ’s world economy relies more than ever on a constant supply of petroleum to fuel a vast number of different vehicles and other applications. Everything from an internal combustion engine in a car to a furnace in a home use a petroleum product as the form of energy needed to make them function. With the burning of oil for energy comes the unwanted side-product of emissions such as carbon dioxide‚ which have now been proven to affect the Ozone and weather patterns

to deal with real challenges for its energy supply‚ especially if this country turned to a sustainable way of producing energy. Thanks to an ideal climate for sugarcane‚ Brazil has a huge resource for supplying the world with the clean and renewable fuel. 88.8% of Brazil’s electricity in 2011 came from renewable energy sources. Wind power provided the largest contribution‚ with capacity up a massive 24.2% from 2011. This increase came as a result of the large amounts of money that were invested

relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for things like electricity‚ heating and transportation. A carbon footprint is made up of the sum of two parts‚ the primary footprint and the secondary footprint. The primary footprint is a measure of our direct emissions of carbon dioxide (CO2) from the burning of fossil fuels. These fossil fuels are coal‚ oil and natural gas‚ they are all non-renewable and currently running out. Some estimates

Every individual has responsibility to use natural resources judiciously. This will give equal opportunity to all to use the resources for the benefit of mankind. One should not be selfish to spend the available resources without thinking of other fellow beings. There is no limit to spend natural resources if available plenty but at the same time one should realize that natural resources are non-renewable sources. The future also depends on such resources. Every individual should think himself or

academic program‚ I had the desire to work on using alternative fuel sources for conserving the environment. This interest of mine received a fillip during my pre-final project where I designed a pressure burner using an alternative fuel source. I prepared a prototype model that simulated an original burner without fabricating the actual burner and accommodated the admission of Jatropha (Alternative Fuel)‚ which is a highly viscous fuel with high ignition point. The project brought in appreciations

called ethyl alcohol is a volatile‚ flammable‚ colorless liquid. The largest single use of ethanol is as a motor fuel and fuel additive. Ethanol is considered to be better for the environment than gasoline. It is a renewable source of energy and it has been seen as a promising alternative to fossil fuel consumption. However‚ there are some negative aspects in the production and usage of this fuel. It is considered to be inefficient and it indirectly affects the environment too. The United States produces

effects of pollution. Prevention of Acid rain is very important for the future of our environment. Since acid rain is caused mainly by the emission of sulphur dioxide from coal-fired power plants. There are a number of preventions‚ including: switching fuel sources to natural gas‚ oil‚ or renewable energy sources; switching to low-sulphur coal; removing the sulphur from the coal before burning; using fluidised-bed combustion processes to burn the coal; and removing the sulphur from the smoke stack after

from fossil fuels. For years‚ we have been drawing on fossil fuels such as coal‚ oil and natural gas‚ as energy resources. However‚ with time these resources have gradually depleted leading to increase in the cost of energy. This had led experts to invent new sources of energy. The invention on renewable energy has not only provided an alternative energy resource but has also come with great environmental and socio-economic impacts. Global warming‚ caused by emissions from fossil fuels‚ has become

This is called “non-renewable” energy resources. Non-renewable energy resources consist of fossil fuels (petroleum‚ coal‚ natural gas) and uranium (nuclear energy). The amount of pollution released from producing energy is a big concern‚ but not all of the energy resources emit the same amount of pollution. The alarming fact is‚ recently‚ many of the
