Reduce Pollution by Using Renewable Energy

Reduce Pollution by Using Renewable Energy

Climate change is the biggest threat to our planet. It is both the easiest and the most challenging issue we have ever faced. The easiest because we know what we must do. The hardest because our current economics are still totally dependent on burning fossil fuels, thereby destroying ecosystems to create everlasting economic growth.

Although there are still some countries like Africa doesn’t have total access to electricity.

Over the years, electricity consumption has increased tremendously.

 

So did the usage of renewable resources has also increased, but not enough compared to non-renewable resources.

           

      It has been 10 years since top voice influencers and climate justice activists, United States presidents, and tech enthusiast CEOs were trying to fight climate change. It is known that the key to tackling the climate change crisis is to end our reliance on non-renewable energy. So, what if we try to use renewable energy for electricity? Can this reduce climate change? Can it avoid using CO2 Emissions, fuel, oil, and gas? We studied and visualized data of countries that used renewable energy and how it affected their environmental pollution compared to others that used non-renewable energy like fuel, oil, and gas. We found that developed countries that were using renewable energy had less ecological pollution by 70% approximately than countries that weren’t using renewable energy.

     

      This descriptive statistical measure demonstrates the huge success of the use of renewable sources of energy to reduce pollution and diminish climate change. Remember there is no planet B. We live in one mother earth; we must protect it.

It is proven that the use of renewable sources of energy decreases the amount of pollution which reduces climate change and, because of this we recommend that the countries should make use of their hydropower, ocean power, wind, and solar energy for electricity and minimize the use of non-renewable energy.

Air Pollution- The Silent Killer

Air Pollution- The Silent Killer

“I want people, when they realize they have been wrong about the world, to feel not embarrassment, but that childlike sense of wonder, inspiration, and curiosity that I remember from the circus, and that I still get every time I discover I have been wrong: “Wow, how is that even possible?”
― Hans Rosling, Factfulness: Ten Reasons We’re Wrong About the World—and Why Things Are Better Than You Think

Air pollution has always been an environmental health threat and a problem that countries suffer from until today. Our analysis starts with an interactive Gapminder  followed by a brief discussion about Air pollution between two countries Sweden and South Africa .

Each caption will  guide you to our main objective that is: Air pollution affects Life expectancies of countries like South Africa where they are subject to a less clean Air (nearly 1 million deaths in  Africa are caused by Air pollution).As Hans Rosling stated: Yes we should be embarrassed .Solving this crucial problem remains a big challenge for all the countries. Therefore, a collective work from citizens and government is much needed to build  cleaner, greener and sustainable cities.

Covid-19 impact on Pollution

Covid-19 impact on Pollution

We all heard that Covid-19 pandemic lock down has some positive impacts on earth. We did a project studying the impacts of Covid-19 on stock market, healthcare sector, flights, and Pollution. The visualization below shows NO2 levels in different continents before and after Covid-19.There was a decrease of NO2 levels in some continents due to lockdown(the factories closing, less pollutants emissions from cars, flights, etc.)
