biofuel an effective substitute for fossil fuel? The planet has been profoundly explored as the human population grows fast. As a result‚ many natural resources are coming to an end. This essay will discuss why it is extremely important to find renewable alternatives that could replace our traditional energy source – the fossil fuel – and focus on successful uses of biofuel‚ which have comparable performance‚ but do not emit carbon dioxide. Fossil fuel is a natural‚ but not renewable‚ energy font

Describe and explain how the use of Fossil fuels may affect the environment and discuss measures‚ which could be taken to reduce the harmful consequences Fossil fuels include gasoline‚ oil‚ coal‚ or natural gas. Whenever we burn them‚ more pollutant gases are emitted into the atmosphere. They are burned to run cars and trucks‚ heat homes and business and power factories and are responsible for about 98% of U.S carbon dioxide emissions‚ 24% of methane emissions and 18% of nitrous oxide emissions.

Introduction to Physical Science: Energy and Fuels Energy is defined as the capacity or power to do work‚ such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms‚ such as electrical‚ mechanical‚ chemical‚ thermal‚ or nuclear‚ and can be transformed from one form to another. It is measured by the amount of work done‚ usually in joules or watts. All known forms of energy can be converted from one form to another. The Law of Conservation

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

Fossil fuels are being used up at a faster rate than they can regenerate. The British Petroleum report provides alarming figures. At the current rate of consumption‚ the coal reserves on Earth will be spent within 110 years. Global reserves of oil and natural gas are even lower‚ and will be spent within the next fifty years respectively. Despite these statistics suggest that fossil fuels are a reliable long-term energy source‚ these numbers are misleading. Due to global population and energy

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS? Mammalian cells are eukaryotic this means that all of their cells have common components‚ membrane bound organelles which prokaryotic cells do not this is shown in figure 1. Organelles are purpose made to carry out a specific function that is necessary within a cell. Due to the specificity of both conditions and concentrations with in these organelles these are compartmentalized. Encasing

However‚ there is renewable sources of energy in wind and solar energy. In Deborah Snow article in the Newcastle Herald titled “Reliance on fossil fuels challenged” she talks about Cameron Clyne position on Australia climate change policy. Cameron Clyne is the former head of the National Australia Bank‚ therefore knows of the economic importance of continuous growth for a global economy. Clyne accepts

fossil fuels due to the lacking of oil‚ gas‚ etc. An alternative energy source is ethanol (C2H5OH). It is an alcohol fuel manufactured by fermentation and distillation of crops that are high with starch and sugar‚ such as grains‚ sugarcane (most commonly used)‚ corn‚ and fruit. Other names for ethanol are ethyl alcohol‚ drinking alcohol‚ and grain alcohol. It can also be made from trees‚ grasses‚ woods‚ and plant waste. It is a colourless‚ flammable liquid that is categorized under bio-fuel. Brazil

The debt over burning fossil fuels and the impact it has caused on climate change as been discussed over years without answer as to say if the gradual warming of the earth is a natural process or if human activity has added to the acceleration of climate change or is the key behind it. Evidence of this is the hockey stick debt as temperature rise rapidly once humans became developed. One thing we do know is that there are many natural events that possibly could accelerate global warming but also
