Can alternative energy effectively replace with fossil fuels? ‘’Fossil fuels are coal‚ natural gas and petroleum.’’ (http://en.wikipedia.org/wiki/Fossil_fuel) They are all organic residues. People use this for their energy‚ fuel and heating requirements. But fossil fuels polluting environment so much and people started to think about using alternative energy for their environment’s healthy. ‘’These alternative energy resources are windy power‚ solar energy and geothermal energy.‘’ (http://en

Coal is a solid fuel formed over millions of years by the decay of land vegetation. Over time‚ successive layers become buried‚ compacted and heated‚ a process through which the vegetation is turned into coal. This means that it’s not possible to keep it going since we can’t wait around for a few million years. Coal was the first fossil fuel to be exploited on a large scale during the 19th century with the beginning of the Industrial Revolution. Production of these fossil fuels is expected to rise

Fossils Fossils are the remains of ancient organisms‚ usually animals and plants but there are also minute bacteria and occasionally fungi. They are preserved by natural processes of burial. Most are entombed in sediment i.e. mud‚ silt or sand which with time transforms into a sedimentary rock such as sandstone. Rarely‚ fossils are enclosed in ash erupted from volcanoes‚ resin that oozes from trees and hardens into amber‚ or natural tar seeping from the ground. Normally only the resistant hard

mean by fossil fuels and explain why they are an attractive source of energy: Fossil fuels are energy sources such as petroleum‚ natural gas‚ and coal which contain the stored radiant energy of organisms that lived millions of years ago (Tillery‚ Enger‚ & Ross‚ 2009‚ p. 67). Fossil fuels are an attractive source of energy because they are accessible and cheap. Describe two different energy alternatives to fossil fuels in detail. Discuss how they work‚ how they compare with fossil fuels‚ and

our country ’s continuous use of fossil fuels is endangering to nature and the wildlife it inhabits as well as the environment that we live in. Our society seems to think that fossil fuels we use in excess today will last forever but actuality will one day be depleted to unrepairable measures‚ which is why we need a cleaner more environmentally friendly substitute. With that said my paper is going to underline how our society would be able to transfer from fossil fuels to cleaner energies which are

Alternative fuels‚ also known as non- renewable sources‚ are substances that can be used as fuels‚ other than conventional fuels. Conventional fuels include: fossil fuels (petroleum (oil)‚ coal‚ propane‚ and natural gas)‚ and nuclear materials such as uranium. [ 1] The fuels we use now are finite‚ meaning they have a limited life expectancy. This along with the toxic waste they produce has made environmentalist and government officials alike take precautionary steps so that we do not

Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. Lately the production of biofuels has been discussed quiet frequently and many people have started focusing on the question if the production of biofuels actually is environmental friendly. Firstly‚ what is a biofuel? Biofuels refer to any solid‚ liquid or gas fuel that has been gotten from biomass. They produce biofuels by growing plants‚ growing sugar

Biofuels Biofuels are Fuels made from Biomass Biofuels are made from plants‚animals‚ or their waste products. Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which

What are fossils? Fossils are the remains or marks of plants and animals that lived a very long time ago. They are usually found in rocks and stones. Fossils are important because they tell us a story about things that lived on the earth before us. What Things Become Fossils? Animals and plants become fossils. So do nests‚ eggs‚ footprints and even animal droppings! How are Fossils Made? Fossils are made from the hard parts of plants and animals‚ such as:-bark‚ seed cases‚ bones and
Premium Fossil Sedimentary rock Dinosaur
Fossils A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground‚ the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from a creature or plant (like a bone). Trace fossils are signs of
