Renewable And Non Renewable Energy Options Environmental Sciences Essay

We cannot use our feet to force our vehicles like the flinstones. So, just how do cars maneuver around? Energy! what is energy? energy is the capability to do work. All living things need energy to expand, vegetation use light from sunlight to expand, also light is a kind of energy we use on a regular basis, we get the majority of the light from sunlight, but at night we make our very own light using another energy source known as electricity. Energy makes things move, cars run on the stored in gas sail boats are pressed by the vitality in the wind. It takes energy to run our televisions, personal computers, and video games by means of electricity, we use electricity all day long, it gives us light and heat, it creates things operate. After a long day not feel too tired to move? Well you have ran out of energy, you need some food to refuel. Think about what your daily life would be without electricity?!

There are two main types of energy; alternative and non-renewable, basically A lot of the energy we use comes from fossil fuels, such as coal, gas and petroleum. Uranium is another nonrenewable source, but it is not a fossil gasoline. Uranium is changed into a gas and used in nuclear power plants. Once these natural resources are used up, they have died forever. The procedure of gathering these fuels can be harmful to the biomes that they come. Fossil fuels are placed through an activity called combustion in order to create energy. Combustion produces pollution, such as carbon monoxide and sulfur dioxide, which might contribute to acid rain and global warming. Apart from Renewable resources of energy can be used again and again. Alternative resources include solar energy, wind, geothermal energy, biomass and hydropower. They create significantly less pollution, both in gathering and creation, than nonrenewable sources. But it is presumed that petroleum in particular will never be depleted as it is made in the deep sedimentary basins even if it will take thousands of years but it'll be produced and petroleum it's still one of main and important resources of energy and the source upon which countries' economies depend upon, in the next report we will attempt to identify different energy options available in the world.

Scientific Background

Renewable energy is described () to be those power source which do not deplete. These are basically natural sources of energy like sunshine, breeze, ----whereas nonren

renewable energy sources :

renewable energy resources are the resources which when used will never be depleted from the earth.

Non-renewable energy resources:

non-renewable energy resources are the options which when used will be depleted from our world and then we must find alternative options.

Data survey

The following section will also show various types of non alternative energy options extracted from (http://www. lshc. co. uk/downloads/Nonrenewable. pdf), such as:

1-fossil fuels:

Fossil fuels are ingredients made from the chemical elements carbon and hydrogen. Fossil fuels shaped millions of yrs ago, through the Carboniferous Period, from the remains of plant life and animals. As the plants and animals that inhabited the swamps died, they were buried under sand and mud which discontinued them from decaying. As time passes, more sediments protected the remains and pressure, together with heat, changed them into coal, petrol and gas deposits.

Today, fossil fuels are used in ability stations to create electricity. Gas is also commonly used in homes to make food and warmth drinking water, and compressed gas can power specially designed vehicles. Petrol is the key source of vitality for vehicles, by means of petrol or diesel.

74% of the UK's electricity is produced from fossil fuels.

Most of the world's oil (13%) comes from Saudi Arabia.

Russia is the primary designer of natural gas, extracting practically 22% of the total produced each year. The UK is 5th with 3. 2%.

China leads just how in coal production, mining 38% of the world's coal.

2-Nuclear power

In most electric power plants, drinking water is heated up and changed into steam, which drives a turbine-generator to produce electricity. Fossil-fueled electricity plants produce warmth by losing coal, olive oil, or gas. In a nuclear vitality seed, the fission of uranium atoms in the reactor supplies the heat to produce steam for creating electricity.

Several commercial reactor designs are currently in use in america. The hottest design contains a heavy steel pressure vessel adjoining a reactor core. Thereactor primary contains the uranium petrol, which is made into cylindrical ceramic pellets and covered in long steel tubes called gas rods. Thousands of gasoline rods form the reactor central. Heat is stated in a nuclear reactor when neutrons reach uranium atoms, creating them to divided in a continuous chain effect. Control rods, which are made of a material such as boron that absorbs neutrons, are placed among the energy assemblies.

When the neutron-absorbing control rods are taken out of the main, more neutrons become designed for fission and the string reaction speeds up, producing more heat. When they are inserted into the main, fewer neutrons are available for fission, and the chain effect slows or stops, reducing the heat generated. High temperature is removed from the reactor key area by normal water streaming through it in a shut pressurized loop. Heat is transferred to a second water loop via a heat exchanger. The also functions to decelerate, or "moderate" the neutrons which is essential for sustaining the fission reactions. The next loop is stored at a lower pressure, allowing the water to boil and create vapor, which is used to power the turbine-generator and produce electricity.

Originally, nuclear energy was expected to be a clean and cheap way to obtain energy. Nuclear fission will not produce atmospheric pollution or greenhouse gases and it proponents expected that nuclear energy would be cheaper and go longer than fossil fuels. Alas, because of construction cost overruns, poor management, and numerous polices, nuclear power ended up being much more expensive than predicted. The nuclear damages at Three Mile Island in Pennsylvania and the Chernobyl Nuclear Place in the Ukraine raised concerns about the safeness of nuclear vitality. Furthermore, the condition of safely disposing put in nuclear petrol remains unresolved. AMERICA has not built a new nuclear center in over two decades, but with extended energy crises across the country that situation may change.

19% of the UK's electricity originates from nuclear power

3-Coal

At the present rate of use, the known coal supplies can last about 300 years and essential oil may not go on for more than about 50 years. A great deal of fossil fuel is burnt in electricity stations. The coal is burnt to boil water which produces heavy steam. The heavy steam drives the followers of a large turbine (an extremely big dynamo) which then generates electricity. The electric current is transported to our houses by large vitality cables. The complete process can be an exemplory case of how energy is changed from chemical substance energy to heat up energy to kinetic energy and then finally to electricity.

Problems with non-renewable energy

The main way to obtain energy today is fossil fuel. However, there are two main problems associated with this kind of gas: the limited option of fossil fuels and climate change. There are also safety concerns from the use of nuclear ability and the radiation that is produced.

Limited availability of fossil fuels

Fossil fuels are non-renewable sources of energy, so they could one day run out. Alternative sources of energy are needed. As items decrease, the expense of buying fossil fuels may increase causing financial problems as well

Climate change

When fossil fuels are burnt they produce the gas carbon dioxide (CO2). Carbon dioxide is actually a greenhouse gas because it traps warmth from sunlight, much like the cup in a greenhouse, stopping it from escaping out of the Earth's atmosphere into space. Greenhouse gases are found naturally in the atmosphere and they're needed for keeping the planet earth warm. However, through the actions of humans, mainly because of this of getting rid of fossil fuels, the amount of these gases in the atmosphere is increasing. As a result, global warming is happening as the temp of the planet earth rises.

Global warming is leading to climate change.

Polar ice-caps are melting, triggering a rise in sea level throughout the world.

Rainfall habits are changing and extreme weather happenings, such as hurricanes and droughts, tend to be frequent in a few parts of the entire world.

The UK is one of 170 countries that contain agreed upon an arrangement called the Kyoto Protocol, which places out targets for reducing CO2 emissions.

There are also some environmental problems with fossil fuels such as:

oil Spills

 

Oil has to be transported from oil fields to where it is needed. Olive oil tankers, which can bring many thousands of tons of oil, are regularly used to move the oil. Regrettably, damages can and do happen and the engine oil spills that result from these injuries have brought on some major environmental problems. Local birds, seafood and animals such as sea otters and seals are very vulnerable to petrol spills. Even though immediate damage can often seem horrific, by making use of careful human being clean-up operations and with natural procedures that help clean the surroundings, the marine ecosystem can usually retrieve well.

 

Figure(2)

Acid Rain

 

When coal uses up, it produces gases like skin tightening and, which are then released in to the atmosphere. Other dangerous gases made by coal getting rid of are sulphur dioxide and some nitrogen oxides. These dissolve in this inflatable water in the atmosphere to make weak alternatives of sulphuric acid and nitric acid, which can then return to Globe as 'acid rainwater'. Sadly many trees and crops cannot prosper when this they need is acidic such as this and large regions of forest can be afflicted. In the most severe cases the vegetation may be killed.

conclusion

In the finish we must know how energy is something we can not put up without as without energy there is no life. For some dangerous energy resources then we must find and start looking for substitute energy sources that are clean and non damaging, we should also commence to depend on green energy resources as we know that they will not be all depleted in the future.
