The Energy Policy Act of 1992 (EPAct) defines alternative fuels as electricity‚ ethanol‚ natural gas‚ propane‚ methanol‚ hydrogen‚ and biodiesel (U.S. Department of Energy‚ What is the Energy Policy Act of 1992‚ para. 2). Gas prices all over the world have been elevated for years‚ giving drivers no other option than to pay the high costs of gasoline with more people driving vehicles that

notably their ability to produce large amounts of natural oils with some diatom species reported to produce a lipid content of between 20%- 40% dry weight (Jiang et al.‚ 2012; Kanda et al.‚ 2011; Liu et al.‚ 2008). In addition to lipid production for biodiesels‚ diatom biomass also contains carbohydrates and proteins that can be used as alternate fuels via carbohydrate fermentation for ethanol‚ anaerobic digestion of proteins to produce methane and photobiological hydrogen production‚ making them a valuable

AGRICULTURE Agriculture is the production of food and goods through farming and forestry . Agriculture was the key development that led to the rise of human civilization‚ with the husbandry of domesticated animals and plants creating food surpluses that enabled the development of more densely populated and stratified societies. The study of agriculture is known as agricultural science. Agriculture encompasses a wide variety of specialties and techniques‚ including ways to expand the lands

Energy demand is increasing day by day owing to our dependency upon fossil fuels‚ which is a limited energy source and also poses negative effect on environment due to CO2 removal. Concerns about increased global energy demand‚ finite natural resources and environmental issues‚ are thus intensifying the search for sustainable‚ clean‚ renewable and eco-friendly alternatives to fossil fuels (Venkata mohan et al.‚ 2008). Renewable energy can be defined as energy that comes from constantly replenished

exports reached a record high due to strong worldwide demand caused by the boom in biofuels (Channel News Asia‚ 2007). Another recent article by an energy expert (Cockcroft‚ 2008) explained that due to the high costs of biomass resources‚ a few biodiesel plants in Asia have ceased operation. This was triggered by the high demand for crops in Europe and other countries‚ triggered by the search for alternative fuels. If not selected wisely‚ bioenergy development may compromise food security

Part of the efforts to save our planet is to shift from using conventional fuels to alternative ones such as wind energy‚ solar‚ tidal‚ wave‚ oceal‚ thermal‚ dendrothermal‚ biogas and biodiesel‚ alcohol and gasohol‚ and agro/industrial wastes. While others may argue that great amount is needed to make that shift‚ we should all realize that its long-term benefits far outweigh the cost of investment. For instance‚ the windmills

Firstly‚ governments need to reduce our dependence on fossil fuels and promote alternatives. Plant-derived plastics‚ biodiesel‚ wind power and solar power are all things that are a step in the right direction‚ but governments need to enforce the limits on CO2 emissions for the polluting industries in their countries for these to be effective. Also‚ individuals can play a
