Due to the use of fossil fuels and their harmful effects on the environment, the importance of renewable energy is increasing. Fossil fuels such as natural gas, oil, and coal are burned to drive engines and generate heat/electricity. However, they are composed of only two elements: carbon and hydrogen. When these compounds burn, the bonds between hydrogen and carbon atoms are broken, and the stored energy is converted into heat energy, thereby forming carbon dioxide (CO2). These harmful gas levels can cause air pollution and climate change, and they are dangerous!
From burning fossil fuels, carbon dioxide is released. This gas has a direct impact on the climate. Another harmful gas emitted by fossil fuels is nitrogen oxide, and it contributes to smog. In addition, fossil fuels contain sulfur compounds. When the sulfur reacts with oxygen and CO2, it forms sulfuric acid, which is acidic and can harm the environment and water supplies. Apart from the negative effects of fossil fuels on the environment, they also have adverse effects on the human body and health. As carbon and hydrogen are two different elements, their combustion releases different gases, such as carbon dioxide (CO2) and water vapour.
While the greenhouse gases effect refers to the increase of the average temperature on the planet, the increase of the UV radiation caused by the greenhouse gases is known as the ozone depletion effect. Ozone is a pollutant that consists of three ozone molecules. If the number of these atoms is increased, the concentration of carbon monoxide (CO) in the air increases and the amount of oxygen decreases. This phenomenon is known as the ozone hole.
The greenhouse gases (GHG) effect is a cause of global warming. This refers to the change in the average temperature of the earth and how it affects it. Greenhouse gases are gases that are emitted from various burning sources such as automobiles, planes, and industrial processes. All the GHGs created by these sources, depending on their concentration and their sources, can absorb heat, thus causing an increase in the surface temperature of the earth. As pointed out above, the GHG emissions are made up of carbon dioxide (CO2) and methane (CH4), but other GHGs can be produced as well. For example, NO2 and oxides of nitrogen (NOx) are also created from smog and traffic. The main focus of greenhouse gases is on carbon dioxide (CO2).
Renewable energy is energy derived from natural sources or renewable resources such as sunlight, wind, rain, and waves. Renewable energy can be defined as energy that can be continuously and indefinitely generated. One of the main benefits of renewable energy is that it reduces greenhouse gas emissions, such as carbon dioxide, while at the same time generating power. For instance, solar energy can be harnessed for electricity generation and a variety of other uses. And, wind power can provide power to homes and communities without emitting carbon dioxide. Other benefits of renewable energy include stability of supply, as it cannot be disrupted by any weather variations.
When compared to fossil fuels, the use of renewable sources of energy is much cleaner. Natural gas, for example, is comprised of only three elements: carbon, hydrogen, and oxygen. When these compounds burn, the hydrogen bonds are broken and the stored energy is converted into heat energy. In turn, the carbon and oxygen atoms of the methane are released, and the carbon dioxide is converted into water vapour. These compounds are not as harmful as fossil fuels and are relatively inexpensive to obtain, unlike fossil fuels. In addition to being environmentally friendly, renewable energy also has many economic advantages over fossil fuels.
To fight climate change, we need to turn to renewable energy. As stated above, wind and solar are some of the most common renewable energy sources. These sources are proven to work well as we can utilize wind and solar to generate power even in the winter! Wind energy (wind turbines) is derived from the wind. People often dismiss wind turbines as noisy or distasteful. These are simply the myths associated with wind energy! What a person sees when they see a wind turbine is a tall tower (actually the blade) that catches the wind and rotates. The turbine has a large mass which is propelled forward by the wind’s direction. The heavy mass pushes against the Earth’s surface. The push from the surface causes the turbine to rotate.
Solar and wind energy are the best alternatives to burning fossil fuels. These alternatives are much cleaner and therefore more eco-friendly, which is why they are rapidly replacing fossil fuels. With the use of renewable energy, we can improve the environment and prevent climate change, thereby promoting a more positive and healthier future.
