Fossil fuels such as gasoline‚ methane and propane contain mostly carbon. When these fuels are burned‚ they react with oxygen and produce carbon dioxide. Because of our heavy use of fossil fuels‚ the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution. The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide. Most of the light energy from the sun is emitted in wavelengths shorter than 4‚000 nanometers (.000004

climate change‚ nuclear energy is considered the key future energy resolution. In favor of greater reliance on nuclear energy‚ Mark Lynas – a climate-science author strongly brought in the reasons of: 1st‚ nuclear power avoiding climate change while fossil fuels have failed to do so and green energy capability is still being questioned; 2nd‚ opponents overstating danger even after many reactors has been safety improved; 3rd‚ the cost is acceptable comparing to other renewables energy. In contrast‚ Peter

energy source. The source may be electricity or fossil fuel but it is clear that everything needs an energy source to run. In the old days firewood was the energy source. After the invention of automobiles and airplanes in early 20th century‚ fossil fuels have been the most prominent source of energy. Fossil fuels fulfill most of the energy requirement of the world because of which energy produced from other sources are regarded as alternative energy. Fossil fuels are found in a limited amount which puts

but the former takes a more natural‚ less energy intensive path‚ while the latter takes more energy input from the use of fossil fuels to power the machines to plant‚ sow and maintain the tree farms. Once the trees are felled‚ requiring energy input‚ it is converted to pulp. The transformation of tree chips into pulp and then paper is an energy intensive endeavor‚ taking fossil fuel inputs to form and shape the paper into a specific product. Some paper products take more processing in order to obtain

with sustainable growth‚ energy needs are increasing day by day throughout the world. At the same time fossil fuels are depleting and lots of environmental issues are coming into picture for addition of any more fossil fuel based power plants. So many countries in the world including Asia Pacific region have placed emphasis on the development of renewable sources of energy in order to reduce fossil fuel consumption and decrease pollution. In the quest for a greener planet and renewable energy sources

we burn many different types of fossil fuels to produce ourselves electricity and to power up our vehicles‚ and so we create a lot of pollution‚ making this our own fault. With our modern technology and the abundance of the sun’s energy‚ solar energy has the ability to provide the world with electricity and different types of fluid (“Solar Energy”). Solar energy is ?e energy source. It is also comparable to fossil fuels in the way that it works‚ but unlike fossil fuels‚ solar energy is pollution-free

consumption had increased because of population increase. Fossil fuels are the most commonly used by industrialized nations (in fact the world at large) these are oil‚ coal and gas which supplies about 90% of the worlds commercially traded energy. Fossil fuels were formed hundreds of millions of years ago; they are an accumulation of energy rich organic molecules produced by organisms as a result if photosynthesis over millions of years‚ fossil fuels are like concentrated stored solar energy. because

said to be similar to other animals‚ but why are humans more intelligent compared to other species? The most widespread theory is that humans evolved from apes and Neanderthals since we have morphological and biological similarities proven by human fossils like bones‚ tools‚ and footprints left by earlier people. These ancestral apes then evolved to humans by natural selection‚ changing their posture‚ bone structure‚ appearance and behavior as the more selectively advantaged apes survived and reproduced
