In other words, if we keep using them, they will eventually run out. But it can be a part of the solution.Read the following article about biofuels and answer the questions that follow.A large dairy farm, Fair Oaks Farms, in the United States of America has found a way to use the endless supply of manure from the cows to generate electricity. Fossil fuels are mainly made up of Carbon. Let's find out why.Get your learners to first do some of their own research about nuclear power and write down their own points. In other words, what are the disadvantages?Some of the disadvantages are listed here (there are others):Although there are many disadvantages to nuclear fuels and power plants, many environmentalists and other people are now starting to change their minds and think that the advantages outweigh the disadvantages. Energy is everywhere! Renewable vs. Non-Renewable Energy Sources What are some ways that you use energy every day? Nuclear power provides about 6% of the world’s energy and 13–14% of the world’s electricity.Following are the examples of non-renewable resources:The first oil well that was drilled in Asia was in Assam, India. Non-renewable energy: fossil fuels. The time to renew this source is short, compared to non-renewable sources, for example, fossil fuels take millions of years to form. Do you remember that we spoke about the atom last term in Matter and Materials? Energy Information Administration: Oil,U.S. Non-renewable energy is energy from fossil fuels (coal, crude oil, natural gas) and uranium.
These natural resources are a major source of power for a vast amount of industries – however, there are numerous downsides to non-renewable energy, including their negative environmental impact and the fact they are in limited supply . We only have one nuclear power station, Koeberg near Cape Town. Remind the learners of the meanings of the terms and then use the activity to see how much they remember from Grade 6. The oil refinery that is found in Digboi is the oldest oil well.There are 7 nuclear power stations in India. It is the Koeberg power station near Cape Town. Essentially, South Africa could benefit as we have multiple livestock farms and agricultural areas which produce a lot of manure and other methane-rich material, which mostly just goes to waste at the moment and is not used. The glass also traps the Sun's energy and keeps the internal environment warm enough for the plants to grow. Have a look at this website to help guide the discussion at the end of this activity.What are some of the advantages of using nuclear fuels instead of fossil fuels? There is now an,Play a simulation to learn more about the greenhouse effect.Find out what else, besides burning fossil fuels, is contributing to an increase in greenhouse gases and write it below.Other sources that contribute to an increase in greenhouse gases are:Energy can be produced by nuclear reactions. A disadvantage is that they produce excess greenhouse gases when they are burnt and that the supply is limited.Discuss, in your groups, the advantages and disadvantages of using renewable energy sources.A major advantage of renewable energy sources is that the supply will not run out and so their use is sustainable. When coal is burnt, it produces heat that is used to convert the water into stream… Natural gas is available deep under the rocks that are found in the underground. In the year 1889, for the first time, oil deposits were discovered in the Assam-Arakan Basin at Digboi. [2 marks].Non-renewable energy sources cannot be reused or replenished. These processes generally take from tens of thousands to millions of years, through plate tectonics, tectonic subsidence and crustal recycling. Therefore, many people see nuclear fuels as an alternative to fossil fuels. (See References 5),Also a byproduct of decomposition, natural gas is mostly methane created as organic matter decays. U-235 must be extracted from mined and processed uranium. It is normally a house made of glass, used to grow plants in. Non-renewable energy is a source of energy that will eventually run out. Non-renewable energy is a source of energy that will eventually run out. Energy exist freely in nature, some of them are infinitely available called renewable, and some are infinity called non-renewable. While there is disagreement among experts on the exact time frame, it is understood that our nonrenewable energy sources will be gone within a few decades minimum or a few hundred years maximum.
