Differences between fossil fuel and renewable energy One of the great issues facing world in the 21st century is how best to obtain the energy for supporting operations: heat and light‚ transportation‚ production and delivery of goods and services. Fossil fuel supplies nearly 90 percent of the energy‚ according to the U.S. Department of Energy. In contrast‚ only %5 is provided by renewable energy. There are several differences between fossil fuel and renewable energy. Fossil fuel are including: oil

CE : Section 5 Fossil Fuels 1. 93 1(c) Alkenes can be obtained from petroleum fractions by a process called ’cracking’. Using a suitable petroleum fraction‚ a student carried out this process in the laboratory and collected the gaseous product over water. (i) What is ’cracking’ ? (ii) Draw a labelled diagram of a laboratory set-up that can be used for carrying out the process and collecting the gaseous product. (iii) An important safety precaution in the experiment is to prevent sucking

to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United States

Fuels Investigation Aim: To find out which fuel gives out the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific

1.0 INTRODUCTION FUEL AS SOURCE OF ENERGY FOR ECONOMIC SECTOR IN MALAYSIA. Energy is the foundation that supports and spurs the socio-economic development of a country. There are many challenges and issues with regard to energy- supply and demand in Malaysia namely energy security‚ fuel supply and pricing‚ especially gas pricing‚ renewable energy‚ energy efficiency and conservation‚ sensitivities of nuclear option‚ and the restructuring of the electricity supply industry (Tan‚ Maragatham‚ and

Petroleum‚ otherwise known as petrol‚ results in pollution during every stage of production‚ this ranges from: mining and recovery to refining‚ transporting and more importantly using it as fuel. Drilling wells is responsible for direct pollution due to oil spills; consequently‚ drilling also leads to the injection of watery liquids into the wells which are later distributed as drilling mud that often cause their own toxic pollution. Furthermore‚ the transporting of such oil by tanker ships have

If synthetic fuel was invented it would change the world economy in many great ways but mainly the U.S. economic would sky rocket. this would allowed for a more consumers era to begging‚ If we notice one of our greatest downfalls in the U.S. would have to be the uprising of the fuel price. this meant a great deal to a lot of business owner for the simple fact that more of there customer base had decrease after the fuel had took a increase‚ Synthetic fuel is far more expensive to process and requires

Select a fossil fuel. How is this fossil fuel used? What are the adverse effects on the environment? The fossil fuel I would like to use and is the most popular fossil fuel would be oil. Oil is used into things like gasoline‚ which is used for very much all of our transportation needs still now and those in the past

Fossil fuels and minerals go as far back as hundreds of millions of years ago. That is before the dinosaurs. Fossils fuels were formed in the Carboniferous Period. The Carboniferous Period occurred about 300 million years ago. In this period our Earth was covered in a swampy plant life. Lots of algae and big leafy plants covered the earth. When these plants died at the bottom of these swamps and lakes ‚they formed something called peat. Then new rock was formed on top of the peat called
