Renewable energy production: Earth saver.
Air Pollution and Carbon Dioxide emissions:
“Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project which is part of the Climate and Clean Energy program at the National Resources Defense Council. In fact, according to the World Health Organization (WHO), it is estimated that each year, air pollution is the major cause of the death of nearly seven million people on Earth. Air pollution has several causes such as:
- Burning fossil fuels
- Industrial emissions
- Wildfires
- CO2 and other greenhouse gases emissions
According to the National Institute of Environmental Health Sciences, it is estimated that deaths due to the devastated air quality will continue to rise till 2100 and the economic value of the health benefits was estimated to be between $50 and $380 for each ton of carbon dioxide emitted.
Ever since the industrial revolution, there was an outbreak of industries in all fields ranging from mechanical production to electrical to technical. All these productions relied mostly on heavy machinery that in fact, combusted energy sources (such as fuel, oil, diesel…) and in a complex series of chemical reactions, released gases. One of those gases is Carbon dioxide (CO2). CO2 by itself is not bad because it is a needed chemical in nature. However, CO2 levels in the air have been increasing drastically to the point that they have become one of the major sources in air pollution, according to MDPI.
Carbon Dioxide from electricity production:
According to the World Nuclear Association, almost 40% of the energy-related CO2 emissions are due to burning of the fossil fuels for electricity production. Because a huge part of electricity production depends on burning fuels, there will be a mass of CO2 emitted to the air. This in turn leads to high CO2 emissions, especially from the countries that depend completely on burning fuels to produce electricity. The visuals below demonstrate and prove that the regions that had the highest CO2 emissions from electricity and heat production in 2014 tended to have the highest air pollution rates. The Carbon dioxide emission rates were highest in the middle east, east Africa and east Asia compared to the low numbers of North America and Europe. The same former countries had the highest air pollution rates (PM2.5) compared to the latter. Therefore, we can conclude that the higher the dependency on fuel combustion for energy production, the higher the CO2 emission rates, the higher the air pollution rates. On the long run, this can have devastating effects on the nature, climate and humans.
What can be done?
After governments realized the devastating effects of the gaseous emissions on the air quality and on humans in general, several attempts were done, such as awareness programs among the youth, restrictive laws and advertising. However, these attempts tackled the tip of the iceberg of the problem. A solution is needed to solve the problem deep from within the roots, to prevent it from happening in the first place. Producing energy from renewables could be a potential solution. The most common renewable power technologies are through Solar, wind, biogas, geothermal, low-impact hydroelectricity and biomass. According to the Environmental Protection Agency, generating energy from renewable sources reduces air pollution, diversifies energy supply and creates economic development.
To reduce the gaseous emissions and air pollution, several countries tried to develop their technological and scientific knowledge of renewable energy production as saw a promise in using renewables, that could one day, be substituted for fuel combustion to produce energy. In fact, developed countries such as USA and the EU countries took serious initiatives to use renewable energy production. The below figures show that countries that increased their electrical energy production from renewable sources over the time period of 2005-2014 had the least air pollution rates in 2014. The EU countries and North America had the highest dependency on using renewables to produce electricity compared to the middle east, east Africa and east Asia and the former regions in turn had air pollution rates that are much lower.
Renewable energy production, therefore, is a clean energy source that can reduce Carbon dioxide emissions and in turn lead to a better, sustainable and a healthy planet that has a rich and high air quality.
