Transcript of Renewable and Non Renewable energy

Renewable Energy BackGround Information Solar Energy Wind Energy Geothermal Energy Hydroelectricity Result Of Survey Conclusion Renewable vs Non Renewable Energy The Sun is our most powerful source of energy.

Can be used for many applications e.g heating, lighting and cooling homes.

Solar energy does not produce waste or pollution and is environmentally friendly. Wind Energy is the kinetic energy that is present in moving air therefore endlessly reliable and sustainable.

Wind turbines are a major example of generating electricity.

Wind Power is the fastest growing source of energy in the world. Around 80 different countries use wind power to generate electricity. Geothermal energy is derived from the natural heat of the Earth.
Geothermal heat pumps (GHPs) use the constant temperature of the earth as the exchange medium instead of the outside air temperature.

Has very low emissions of greenhouse gasses therefore has minimum negative environmental impact. Hydroelectricity is a form of Hydro power and is the most widely used form of renewable energy.

. It produces no waste and does not release greenhouse gases.

China is currently the highest generator of hydroelectricity. It is produced by using organic material on the Earth's surface and converting them into other forms of energy for example: Burning wood.

Biomass contains stored energy from the sun as plants use photosynthesis to grow and produce biomass.

Biomass plants burn biomass fuel in boilers to heat water and turn
a steam turbine to create electricity. Renewable Non Renewable Q5) What is your preference of Renewable and Non Renewable energy? Non Renewable Renewable Non Renewable Renewable Q6) Do you have anything against Renewable and Non Renewable Energy? Non Renewable Renewable Q7) Do you think it is expensive? Non Renewable Renewable Q1) Can you name any types of Renewable and Non Renewable Energy? Non Renewable Renewable Q2) Can you name any Advantages of Renewable and Non Renewable energy? Non Renewable Renewable Q3) Can you name any Disadvantages of Renewable and Non Renewable energy? Q4) Give a location in Ireland of Renewable and Non Renewable energy Renewable energy is natural energy source which does not have a limited supply. Renewable energy comes from natural sources such as sunlight, geothermal heat, wind, water, and bio fuels. Biomass Background Information Fossil Fuels Crude Oil Gas Coal Non-Renewable Energy Advantages and Disadvantages
A major advantage is that it produces little or no waste products such as carbon dioxide or other chemical pollutants, so has minimal impact on the environment.
A disadvantage of renewable energy sources is the reliability of supply. Renewable energy often relies on the weather for its source of power. Non-renewable energy sources are natural resources that have been formed in the earth for over millions of years.

These sources of energy are consumed much faster then they are regenerated.
Non-renewable resources can generally be separated into two main categories; fossil fuels and nuclear fuels. Fossil fuels are derived from organic matter which has been trapped between layers of sediments within the Earth for millions of years. They are difficult to obtain as they are typically retrieved through drilling or mining. Crude oil is a non-renewable resource that builds up in liquid form between the layers of the Earth’s crust.

It is retrieved by drilling deep into the ground and pumping the liquid out. Natural gasses gather below the Earth’s crust and, like crude oil, must be drilled for and pumped out. Raw natural gas is a mixture of different gases. Its main component is methane. Created by compressed organic matter, it is solid like rock and is obtained by mining.
Coal is most typically used in home heating and the running of power plants. Nuclear Fuels Nuclear energy comes from uranium, a non-renewable resource that must be mined. Mined, refined, compounded. Uranium begins to break down and release energy which heats the water it is immersed
in. Advantages and Disadvantages One advantage of non-renewable energies is that right now, they seem widely available and affordable. Oil and diesel are still good choices for powering vehicles. Pollution grows greater through the by-products they leave behind and mining of non-renewable energy is causing damage to our environment The main aim of our project was to recognise the difference between renewable and non-renewable energy and find out the consumptions of them. The information we got made us able to distinguish between renewable and non-renewable energy. To find out the consumption of these energies our group carried out a survey, our results show majority of respondents could comprehend the differences between renewable and non-renewable energy. The pie charts compare both concepts of renewable and non-renewable. In conclusion, we see that renewable and non-renewable energy are easily differentiated within the community. Our results show renewable energy is widely recognised as clean and safe way for energy production in comparison to non-renewable which is environmentally damaging and limited. Examples are Crude Oil, Natural Gas, Coal It accounts for 90% of worlds transportation fuel. Composed of carbon, hydrogen, oxygen, nitrogen and varying amounts of sulphur. It does not produce toxins and is environmentally friendly. Humans are using fossil fuels 100,000 times faster that they are being made. The big advantage of renewable energy is that it is less polluted so has minimal impact on the environment.
The advantage of non-renewable energy is that right now, they seem widely available and affordable
For example when asked to name different types of renewable and non-renewable energy as many as 34% answered solar and wind as compared to 32% stated oil for non-renewable
