Most countries who still use coal as source of energy, have a problem with air pollution, thus making the world hotter and more unbearable because of worsening global warming. People use more electricity for aircon that overloads the capacity of power plants, and reach for a desperate, quick fix solution by installing coal power plants. So, this is a real dilemma facing our world today.
The answer lies to a compromise since our country can’t afford renewable energy (which I see renewables save more money in the long run because sunlight and wind are free forever). Anyway, our country opted to put more coal power plants. So, how do we make coal more viable alternative other than the more expensive renewables?
After searching for answers, coal is bad for the environment (period), but the solution for making the most out of coal is to make the power generation more efficient. Through the advent of modern technology, there are power plants that are more efficient, and produce less emissions. What is the role of smokeless coal?
Smokeless coal as stated, produces less emission, or less smoke, which harms the environment. It produces more heat that converts more to electricity. And, it is cheaper than gas! (because of rising oil prices worldwide).
For more information, you could read the details in Wikipedia: https://en.wikipedia.org/wiki/Smokeless_fuel
In summary, there are clear ways to solve our energy woes by using renewable energy. However, it’s hard to convince governments to use this because of upfront costs, and so opted for a more conventional form of sources of energy because they argue it’s more cheaper. Using smokeless coal together with efficient power plants could lessen the impact to our environment and make time to save money to buy renewable sources of energy for our future.

If they can do it, we can do it! 🙂
To achieve efficiency of power plants, we could use a machine that converts heat into electricity:
Thermoelectric Generators (TEGs):
TEGs use the Seebeck effect to directly convert heat into electricity.
When there’s a temperature difference between two sides of a thermoelectric material, it generates an electric voltage.
TEGs find applications in power plants to recover waste heat and improve overall efficiency.

Note: Although, as stated, this machine has high production costs, and so it must be developed further in using cheaper materials to make it more affordable in the future.
For emergencies, when power plants are overloaded, we could employ power barges:
These are floating power plants where you can use if there is yellow or red alert state of calamity in the regions affected. This is what the ex-president Fidel V. Ramos did when there was an electricity crisis years ago and it was effective, for there were no blackouts in the country.
These are temporary solutions that could help mitigate our energy crisis, and so we must find ways to ease the burden using cheaper wind turbines and cheaper solar panels. Renewables in my opinion are the future of energy for our children and children’s children.
