give 2 advantages and 2 disadvantages of using renewable and non renewable resources
Answers
- Advantages of Renewable Energy:-
One major advantage of renewable energy is that it is sustainable and will never run out. They provide clean energy because they are non-pollutant and non-contributor to greenhouse effects and global warming.
Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation.
Renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so have a minimal impact on the environment. Unlike coal, renewable energy pays off its carbon footprint and does so relatively quickly. Depending on where they are made, solar panels offset their carbon footprint in about four years.
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.
- Advantages of Non-Renewable Energy:-
Non-renewable energy sources cannot be replenished in a short period. They include fossil fuels such as oil, natural gas, coal, and uranium used for nuclear energy.
The main advantages of non-renewable energies is that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles. Non-renewable energy is cost effective and easier to product and use. According to NG (National Geographic), there are reservoirs of non-renewable energy sources throughout the world.
- 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.
It can be 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.
Renewable energy often relies on the weather for its source of power and this can impact the reliability of a consistent energy supply. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors require 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.
- Disadvantages of Non-Renewable Energy:-
On the other side are the disadvantages to non-renewable energy. Solarschools indicates that once sources of non-renewable energies are gone they can't be replaced or revitalized.
The mining of non-renewable energy and the by-products they leave behind causes damage to the environment. There is little doubt that fossil fuels contribute to global warming. When fossil fuels are burned, nitrous oxides causes photochemical pollution, sulphur dioxide creates acid rain, and greenhouse gases are emitted.
A major disadvantage of non-renewable energy is the challenge of breaking humans of their habit of leaning on it. The Union of Concerned Scientists reports it's an uphill battle to sway consumers that the so-called "public goods" of renewable energy, such as reducing pollution for everyone, may not be enough to convince them to pay more for cleaner energy.
As countries disagree through wars and differences, the prices of non-renewable energies such as oil has become a commodity where price fluctuation is always eminent. The burning of fossil fuels continues to rise producing high levels of carbon dioxide (CO2) which climatologists believe is a major cause of global warming.
