Why are Coal-Powered Power Stations harmful to the Environment?

Why are coal-powered power stations harmful to the environment?

Fossil fuels are indeed the top fuels used all over the world for generating power and electricity. Among the fossil fuels, coal is the most widely used fuel in power plants. Coal-fired power plants boiler use different kinds of machinery that convert heat energy produced from combustion into mechanical energy. Coal, gas, and oil are fossil fuels responsible for most of the world’s electricity and energy demands. Coal, which is readily available in most of the developing and developed world, has been used as a major source of fuel even in ancient human civilizations. It also found its use in historic steam engines at the dawn of the industrial revolution.

There are many advantages to coal power stations like Reliability, Affordability, Safety, etc. but as much as coal is reliable and affordable how safe is it?

The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.

Air pollution from coal power stations causes disease and kills thousands of South Africans every year, says UK expert. Air pollution from coal-fired power stations kills more than 2,200 South Africans every year and causes thousands of cases of bronchitis and asthma in adults and children annually.

In 2016 these were the statistics that were provided by Dr Holland to the Department of Environmental Affairs and to members of the Environmental Affairs and Health Portfolio Committees

2 239 deaths per year: 157 from lung cancer; 1 110 from ischaemic heart disease; 73 from chronic obstructive pulmonary disease;719 from strokes; and 180 from a lower respiratory infection
2 781 cases of chronic bronchitis per year in adults
9 533 cases of bronchitis per year in children aged 6 to 12
2 379 hospital admissions per year
3 972 902 days of restricted activity per year
94 680 days of asthma symptoms per year in children aged 5 to 19
996 628 lost working days per year
All these statistics and yet the Minister of Mineral Resources unveiled the long-awaited Integrated Resource Plan, saying “coal will continue to play a significant role in electricity generation. This is a 10-year plan which includes increasing the country’s current 47,000 megawatts of energy by 1,500 megawatts from coal, 2,500 megawatts from hydro, 6,000 megawatts from solar and 14,400 megawatts from wind. Mantashe said coal would contribute 59% of the country’s energy, as “the country has the resource in abundance” and coal-fired power plants “are going to be around for a long time.”

For clean fresh air, we must say no to coal. It continues to fuel climate change, supercharge extreme weather events, poison our air and consumes precious freshwater.

Cheap is not always Better – You get what you Pay for

posted in: General 0

Everyone wants to save an extra rand! However, in our pursuit of savings, there are areas where we should not skip especially when it comes to building a home, regardless of the size or location, its always costly… and these days with the cost of living only getting higher, building a home has become increasingly expensive.

When we think of building a home… the first things that normally come to mind are: “Bricks, sand, roofing, tools, painting oh and lets not forget the labour.”

Anyone who has built a home or considered building a home has likely heard the term “builder grade/ Contractor grade” materials. These matertials are just for temporary use not long term measures. When there are so many details to consider, a potential homebuilder may not look as deeply into understanding what these materials are and how they can affect your home down the road.

For example: Bricks: we know for one that it is time consuming because it cannot be used in high seismic zones. Bricks absorb water easily, therefore that can cause flouroscene when not exposed to air. We know that bricks have a less textile strength and the rough surfaces of bricks cause mold growth if not properly cleaned. The cleaning of brick surfaces is a job that can be quite difficult because the colour of low quality brick changes when it is exposed to the sun for long periods of time.

Everyone wants to save these days and we see this everywhere, with our clothes and electronics and even food. However, when it comes to our assets like our homes, cars and jewellery we need to consider spending a few extra rands. We really need to think of the long term effect and whether the specific item will last us for the next 10 or even 15 years. We tend to spend because an item is on sale not necessarily because we need it at the time. Time! Yes, it is such an imperative factor, because it is something we can never get back. Let us ask ourselves, is this going to sustain me for the next 10 years or will this perish within a few months.
When we consider Building, we see that it is about creation. We create with the heart, but we envision from the mind. We create to help and support people but in order to do that in a way that is effective and long lasting, we need to be able to forecast the unpredictable weather conditions like the current flood we are experiencing throughout KwaZulu Natal.

“Cheap is not always better, you should get what you paid for!”

Common misconceptions about demolition

posted in: General 2

Common misconceptions about demolition

What is demolition?

Demolition derived from the verb demolish: to completely destroy a building, especially in order to use the land for something else.

When I think of demolition, I think of buildings collapsing, loud bangs, big machines, and building areas being closed off. Due to demolition becoming very messy.

I have to admit I didn’t know much about demolition, especially since most of the sites are usually covered up when you go by, but I have to say thanks to Google. As I have learnt that there is a lot that goes into demolition and behind the scenes. I even learnt what demolition is.

“Though demolition is an important part of the life of our cities and neighbourhoods” – Demolition 101

When it comes to demolishing a building it is not as easy as one, two, three. There are many factors that come into play, e.g.: Professional machine operators, proper equipment, and the most important of them all a plan.

 

1. Buildings don’t just fall, and implosions are just one percent of demolition work. Machinery such as excavators and backhoes do most of the work.

2. Demolition contractors help preserve and restore historical buildings.

3.  The personnel using the machinery need to undergo the proper training on how to use the equipment the right way. Especially since we all know that technology is constantly evolving, so the machine operators need constant training to keep up with the changes.

4. Contractors do not just knock buildings down for fun. It’s their job.
