Renewable energy is energy that can be used over and over again. It never runs out. It is also better for the environment. I think that renewable energy is definitely an option for South Africa in the near future. There are many different forms of renewable energy and I’ll talk about the forms of renewable energy which would be most suited in South Africa. Solar Power would probably be the most successful form of renewable energy in South Africa. The reason why I say this is because South Africa is a country that has a reputation for sunny weather. This fact is true as South Africa is the 5th sunniest country in the world1. There are various different ways in harvesting the sun rays to convert it into electricity. The most successful way of harvesting the energy for only your household would probably be the Solar Water Heating method. The way it works is it uses the heat from the sun to heat a liquid inside the cylinders. The liquid then turns into a gas which supplies power to the generator which creates electricity. The Solar Water Heating method is more successful than the photovoltaic method because the photovoltaic method converts the light directly into electricity. This means that the photovoltaic method cannot store the electricity and is only able to function when there is sunlight2. So for the Solar Water Heating method if it was an overcast, rainy day, you would probably still have enough electricity to power all the essential requirements as the electricity would’ve been stored. A solar water heating system costs about R20000 so the cost is initially high but in the long term it is very efficient as your electricity supply is free. The government could also consider investing in a solar furnace. It is a massive collect... ... middle of paper ... ...vest the lightning strikes into electricity in the near future. In conclusion, I believe that we should still continue to use the remainder of fossil fuels available but the governments all across the globe should start considering the use of renewable energy only. We could possibly store the fossil fuels and use it as back up because not all forms of renewable energy are completely reliable. But having said that, we should also learn how to conserve our energy and do small things such as turning off your light when you walk out of your room. Even if the government doesn’t start considering renewable energy soon, nothing’s stopping you from investing in your own solar geyser or trying to get involved by promoting this recent form of energy. It is good for you as you save money and good for the Earth’s future as it reduces the emissions in the Earth’s atmosphere.
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.
From the home to factories, families and industries are reliant on the use of nonrenewable fossil fuels to feed the needs of the everyday human. Fossil fuels are the main source of energy over clean, renewable sources such as the use of wind, solar energy, and water to power our homes, schools, and industries. In fact, about 85% of energy use comes from fossils fuels. The main reason being that using fossil fuels is cheaper than wind and solar energy. “For nearly two centuries, fossil fuels have been the cheapest source of energy” and widely abundant (Marburger, A global framework: international aspects of climate change). However, overtime fossil fuels will disappear due to the lack of time to replenish itself with the human races rapid use of it. Despite its current status of availability, there are many controversial issue in using fossil fuels; the most prominent issue being that it is the cause of rapid climate
Every day the world we live in dies a little more. By this I mean the physical world is gradually being damaged by the way we treat it. We need to start looking at the kind of environment we are creating and decide if it is a place that we want our children and the future generations to have to suffer though. If your answer to the previous scenario is no then you should really consider what we can do to make the future a better place. One of the best ways that I can think of is by focusing on the advancements of green energy resources. By doing this we will not only reduce pollution produced by burring fossil fuels but mainly we will be able to reduce the amount of pollution produced from the gathering of them though means like fracking.
Fossil fuel has in a sense fueled our economy and way of life for decades, and in many ways we have taken these resources for granted. Eventually they will run out or the price per barrel will be so astronomical that the average American will not be able to afford to buy gas. Renewable energies have the power to save our environment and change the world as we know it. The most important thing that we, as Americans need to do is to be open about other options that become available to us.
We depend on energy; nothing in our daily lives could be possible without it. Electricity primarily comes from burning fossil fuels or using nuclear reactors. But the plain truth is, we are running out of fossil fuels. Our known oil deposits will run out in approximately 35 years, and if we increase the use of natural gas and coal to make up for the energy loss, our natural gas will last for 45 years and coal deposits will deplete in 75 years.
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
South Africa wastes lots of money on non renewable energy sources in order to create electricity for example coal. The building of Wind Turbines, Hydroelectric power plants etc. Are costly, but once built are free as they use renewable energy sources. They do not contribute to global warming unlike nuclear power plant which is extremely bad for the air. There is also a risk of an accident such as the Chernobyl accident.
“Is Renewable energy an economically viable option for South Africa?” “Renewable Energy is a source of energy that is not exhausted when used.” “Economical means giving good value in relation to the resources used or money spent.” “Viable means capable of working successfully; feasible.” (Soanes, Hawker & Elliot et al., 2005)
There are different kinds of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from natural resources. Although renewable energy can be expensive to build, it has less environmental damage in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources.
Solar power for instance is one of the most popular and easiest of all of the renewable energy sources to harness, especially for home and business uses. (Galbraith) For around the same ...
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
With the depletion of fossil fuel resources comes speculations and debates about alternative energy sources. The world, including the Philippines, is practically dependent on a dwindling non-renewable source of energy. Today, experts are debating about and considering three options: Nuclear, Solar, or Wind Energy. Everyone has been accustomed to the bad image of nuclear energy as a result of the Chernobyl and Fukushima incidents above all others. The popular belief is that radiation from a nuclear meltdown is very harmful to humans and other living things—which is true—and that nuclear power plants are very dangerous and not ideal—which is not. According to Smith, et. al (n.d), all the nuclear disasters that ever occurred were caused by human error and natural disasters like tsunamis, not one because of system failure. Putting the false beliefs aside, with proper engineering and adequate maintenance by experts, a nuclear power plant is a very ideal and viable source of energy for the following reasons:
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
...outcompete fossil fuels, but by using different forms of alternative energy fossil fuels use could be reduced drastically. Now is the time for a conversion from fossil fuels to alternative energy.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
