Examples Of Renewable Energy
Energy is the prime component of all things running in the universe. Earth uses one very small fraction of the suns energy to sustain its life through the process of photosynthesis. Photosynthesis further leads to production of oxygen and glucose which are the source of survival for humans and all living beings on earth.
The energy used in the form of mechanical, kinetic or electrical energy also sources itself from the solar energy or from the product of photosynthesis directly or indirectly (Fossil fuels). Energy is one of the major inputs for the economic development of any country. In the case of the developing countries, the energy sector assumes a critical importance in view of the ever-increasing energy needs requiring huge investments

1.2.1 FOSSIL FUELS
Fossil fuels form the crux of energy use in the world today. 70% of the energy production and 98% of the vehicles on road are run on fossil fuels.
There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – hence the name fossil fuels, from about 360 to 286 million years ago. At the time, the land was covered with swamps filled with huge trees, ferns and other large leafy plants. The water and seas were filled with algae. As the trees and plants died, they sank to the bottom of the swamps of oceans. They formed layers of a spongy material called peat. Over many hundreds of years, the peat was covered by sand and clay and other minerals, which turned into a type of rock called sedimentary.
More and more rock piled on top of more rock, and it weighed more and more. It began to press down on the peat. This pressure caused the water to come out of it and it eventually, over millions of years, turned into coal, oil or petroleum, and natural
Salton Basin Research Paper
1988 Words | 8 PagesThe lower parts have been submerged and desiccated, shown by the layers of travertine, strand formations, and beaches (9). Scientists can infer that the basin was once filled with seawater due to the discovery of fossilized marine shells, corals, and oysters in the rock (9). The fossils are now above tide-level showing a change in elevation of the region (9). Dr. Stephen Bowers, who studies the region, writes, "The water of the old Tertiary Sea, which once prevailed here, must have been extremely favorable to the propagation and growth of mollusks, especially oysters”. There is also evidence of volcanic activity around the area in the form of craters stemming from Pinacate, an extinct volcano (9).

953 Words | 4 PagesThey are two crucial aspects to the topic of energy, but are not included by the UN. A determinant reason that millions of people across the globe have to resort to biomass to cook is that the cost associated with modern energy makes it less accessible (Birol, p.1). This unfortunate situation is due to many reasons. A key reason is that many of the resources required to install energy plants are disproportionally controlled by a few geopolitical actors. This causes large fluctuations on the commodity prices all over the globe, making not only modern energy, but also other basic human development targets, such as shelters and transportations less attainable (Regnier, p.2).
Energy As Renewable Energy: Chocolate As Renewable Energy
1666 Words | 7 PagesChocolate As Renewable Energy Have you ever heard of chocolate as renewable energy? Well it is, chocolate might just be the next renewable source of energy. Research from the University of Birmingham in the UK suggests that by extracting hydrogen from confectionary(food items that are rich in sugar and carbohydrates) waste- a process that may have a huge impact on the future handling of food waste and its potential as a supplier of renewable energy.(Renewable Energy World. 2006) Chocolate as a renewable energy resource could bring us the benefits of a new way of making energy, a way to handle food waste, and a better and cheaper renewable energy. Thinking that chocolate could be our source of energy is very absurd.

Persuasive Essay On Solar Energy
1889 Words | 8 PagesIt is commonly known throughout human history that the energy used is burned from coal which creates biomass. During the Industrial Revolution, coal was an essential need to everyone, hence the discovery of oil as a substitute. Yet, the mass formation from the unearthing of oil causes more damage than benefits for the planet. Humanity had never seen a more compatible source in which came a higher demand for oil. As the public has urged to generate more oil, scientists theorized that fossil fuels will eventually run out, making way for a renewable energy route in the future (Mason).

Non Renewable Resources Essay
1700 Words | 7 Pages2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
