Advantages and Disadvantages of Non Renewable Energy Unlike renewable energy, non-renewable energy sources, such as coal, gas, and oil, will become heavily depleted over time. That may call for a look at both the advantages and disadvantages of non-renewable energy and their current outlook. What Are the Advantages and Disadvantages of Non-Renewable Energy? There are many arguments both for and against non-renewable energy. These include: Advantages of Non-Renewable Energy Because non-renewable energies seem abundant, like oil, gas and coal, some experts believe if channeled correctly, our supplies will be safe for future generations. Non-renewable energy sources include oil and petroleum products, gasoline, diesel fuel, and propane, natural gas, coal, and uranium used for nuclear energy. Some environmentalists include our forests, trees, and plant life as a non-renewable energy source as well especially due to the deforestation of our forests. 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. They are cost effective and much easier to produce and use. Non-renewable energy also has market value where a supplier or manufacturer makes money and pays workers enhancing economies. Although governments struggle with fair trade practices, many countries have a non-renewable energy source which can used as a bargaining tool to help their economy stay afloat. Disadvantages of Non-Renewable Energy On the other side, there are many disadvantages to non-renewable energy. Because non-renewable energies come from sources on our planet, once they are gone they can't be replaced or revitalized. Pollution grows greater through the by-products they leave behind and mining of non-renewable energy is causing damage to our environment. There is no doubt that fossil fuels.
Renewable energy sources are being used all over the world. Brilliant minds have devoted their lives to finding resources that do not leek greenhouse gases into the ozone, or cost large amounts of money. In the Video “New Energy Revolution,” it shows some of the renewable energy sources being used all over the world. For example, wind energy, solar power, Hybrid cars and using methane gas for stove fuel. These are all excellent examples of renewable energy as they are all affordable and convenient as well as being efficient. The question is, will people use them, or stay with the atmosphere damaging fossil fuels of today? Solar power is an excellent energy resource. The sun gives us free rays, so why not use them as a power source. The video shows Japan as a country which is educating their people about the risks of keeping the current resources and providing information on renewable energy sources, like solar power. Solar power is set out in a row of panels which take in the suns energy and provides power for homes and other things. Cars can now be solely power by solar panels, creating huge possibilities. If solar energy was used world wide, along with other renewable sources, the world would be cleaner and more pleasurable to live in, knowing that the greenhouse gases are under control. Hybrid cars are cars that run on electricity (charged) and some gas. The Hybrid car was invented to cut down the hazardous gases that are emitted by normal cars. The Hybrid car emits 90% less greenhouse gases than the normal car and inventors want to make it 100%, meaning no gases emitted. Toyota is leading the pack in terms of producing a usable, affordable Hybrid car. The car is charged at places similar to petrol stations with an electric charger that easily plugs into the front of the car. This marvellous invention only runs on gas, when it is doing speeds of 100 kilometres per.
One major advantage with the use of renewable energy is that as it is renewable it is therefore sustainable and so will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation. Even more importantly, renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so has minimal impact on the environment. Renewable energy projects can also bring economic benefits to many regional areas, as most projects are located away from large urban centres and suburbs of the capital cities. These economic benefits may be from the increased use of local services as well as tourism. The Disadvantages of Renewable Energy It is easy to recognise the environmental advantages of utilising the alternative and renewable forms of energy but we must also be aware of the disadvantages. One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. This may mean that we need to reduce the amount of energy we use or simply build more energy facilities. It also indicates that the best solution to our energy problems may be to have a balance of many different power sources. Another disadvantage of renewable energy sources is the reliability of supply. Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors need clear skies and sunshine to collect heat and make electricity. When these resources are unavailable so is the capacity to make energy from them. This can be unpredictable and inconsistent. The current cost of renewable energy technology is also far.
