Looking closely at biodiesel, we find that its physical and chemical properties are very similar to petroleum based diesel fuel in terms of operation in compression ignition engines (diesel engines). Therefore, biodiesel can be used in diesel engines without expensive alterations to the engine or fuel system.
When it comes to listing the advantages of biodiesel, there are many and advocates say these include low emissions, better scent, and higher lubricity. According to a DOE report, biodiesel has a lower energy content than regular diesel, but performs as well as diesel when mixed with diesel in blends of up to 20 percent.
The possibility of bio-diesel has been around for a long while, but it is only now, as oil appears scarcer and less secure that people are starting to invest in …

As swanky electronic gazettes have become the new lifestyle status symbols of the modern society, more and more people have started taking to adapting and flaunting latest technology equipments. The usage of mobiles, laptops, mp3 players, computer, LCD TVs and home equipments with advanced technologies have become common. With new upgrades in technology everyday, old equipments are fast phasing out because of obsolence. This obsolete, non-working, non-repairable but durable equipments obviously find there way into the garbage.
According to N.M. Taphani, Regional Officer, Pollution Control Board, this Electronic Waste is highly dangerous for environment and hence should not be disposed with the regular garbage. Electrical and electronic equipment are made up of a multitude of components, some containing toxic substances which can have an adverse impact on human health and the …

Most of our energy comes from burning fossil fuels, this creates a lot of pollution. The other problem with fossil fuels is that they are quickly running out, some experts have suggested that within 50 years our supplies of fossil fuels will of run out. That would cause huge problems for generating power and running vehicles. One of the best alternative methods of generating power so far is solar power.
Solar power is so good because it’s reliable, clean and doesn’t cause any pollution. These panels collect sunlight and convert the suns energy into electricity. This sunlight can be used in a number of different situations, be it factories or homes. Solar panels are suitable for commercial and private use.
Reasons Why We Need Solar Energy
We have been dependant on fossil fuels …

Human activity invariably has an impact on the earth’s ecology through changes to the environment. Major impact drivers are energy and transport, resource use and waste production, and water use and management. These drivers are, however, not exclusive to each other and in fact have considerable overlaps.
Examples of these overlaps are the interdependence of water and energy/power production, the extraction and use of fossil energy resources and the production of wastes, and the utilization of energy for the production and distribution of agricultural and potable water.
Water and Power
Water in the power industry is utilized in many ways, including:
1. steam production for spinning turbines,
2. humidifying air flow into gas-turbines,
3. inter-cooling air in gas-turbine plants,
4. steam injection for nitrogen oxides control,
5. acting as a heat transfer medium in some nuclear plants,
6. condenser …

There is much concern at the present time about the increasing addition of green house gases to the earth’s atmosphere. A prominent greenhouse gas is carbon dioxide. This gas is produced when fossil fuels are burnt to produce energy for driving our automobiles or for producing electricity in power plants. It is believed that increasing addition of carbon dioxide into the atmosphere will result in adverse changes to the earth’s climate such as global warming to the extent that many presently inhabited areas of our planet will become inhabitable.
As a result of the concern caused by the emission of carbon dioxide from power plants it has been proposed that the use of fossil fuels should be restricted and a greater emphasis should be laid on alternative sources of energy such …
