look into the still tiny alternative energy market. In a minimum of fifty years fossil fuels‚ which include petroleum (oil)‚ natural gas‚ and coal‚ will all run out. Alternative energy is a renewable and the most productive type of energy for the USA and the world (United States. Department of Energy). Every person on this planet is provided with a dirty and unforgiving energy source‚ fossil fuels. Fossil fuels destroy and tarnish the once beautiful world. Alternative energy could slowing bring

1301 24 June 2012 Effects of Ethanol in the Society Ethanol‚ also 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

like coal burnt in the industries release CO‚ CO2‚ SO2 and so on. These gases are harmful as they cause global warming‚ acid rain‚ breathing problem and so on. For this‚ energy renewable sources like biomass are taken as a good alternative source of fuel. Also some other efficient alternative source of energy can be explored so that the industry flourishes without much impact on the environment‚ where people and other organisms dwell upon. In one way‚ exploring eco-friendly-alternative-source of energy

But they are known as fossil fuels because they are made from decomposed plants and animals that have been buried in the ground for millions of years. Biofuels are similar‚ except that they ’re made from plants grown today. Hoekman’s book‚ Renewable Energy: An International Journal‚ which I read on October 24‚ says they’re produced from living organisms or from metabolic by-products such as organic or food waste products. In order to be considered a biofuel the fuel must contain over 80 percent

WTHESIS STATEMENT: “BIOCONVERSION OF WATER HYACINTH (EICHHORNIA CRASSIPES) TO ETHANOL.” 1. INTRODUCTION Water hyacinth (Eichhornia crassipes) is a free-floating or rooted in mud plant or weed which can totally cover fresh water lakes‚ harbors‚ and other essentially relatively occluded fresh water bodies. It is a fast growing permanent aquatic plant that are extensively scattered all throughout the world. This tropical plant can be the reason for the infestation over large areas of water resources

ABSTRACT This study proposes that mechanical pretreatment of the algae Ulva reticulata will increase the percentage of ethanol produced. Two batches of sample will be prepared. The first will serve as a control. The second will be subjected to maceration. The two batches will undergo dilute acid hydrolysis. The sugar released will then be fermented to produce ethanol. The ethanol yield of the two batches will then be compared. The result of the comparison will justify the effect of mechanical pretreatment

Global Fuel Cell - Market Analysis and opportunity Assessment 2014 - 2020 : Future Market Insights Global Fuel Cell - Market Fuel cells convert electrical energy sourced from chemical energy‚ through an electromechanical reaction with oxygen or other oxidizing agents. Primarily‚ a fuel cell functions as a battery‚ but is different in the way that in a fuel cell‚ fuel is supplied from an external source and fuel is converted to electricity without any involvement of a burning process. The demand

The world is undergoing a transition period between a phase of fossil fuel energy to a phase of clean and renewable energy. There is urgent need for the planet to develop a new range of renewable energy sources which are less carbon intensive and which will open up a new age for fuels. In such a scenario‚ the 21st century will be a transitional period for energy generation and consumption. It is probable that the world is moving towards a greater diversity in primary sources‚ in which each country

After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution‚ cheap fossil fuels then became the main source of energy. However‚ faced with the notable increase demand for energy‚ fossil fuel‚ as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem‚ the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy. This
