Why do we need alternative energy?
Why do we need alternative energy. Global warming, and climate change are issues that we need to take care of today during our lifetimes. If we love our children, our grandchildren, and others to be born after them.
Watch my video below instead of reading the article.
As far as being concerned there is not much for us to worry about. Because the world will go on and we have our water resources intact for now.
We do not have to wear pollution prevention masks whilst we step out of our homes. We don’t need to be in darkness without the luxury of electricity. Plus, many other good things which we are enjoying today.
Imagine our great, great, great, great, grandchild and that is five generations away. One and a half centuries hence what would the world be. If the changes that are happening around us in little doses are not taken care of now?
Global warming would melt the glaciers of ice in the North and South Poles. And assuming that all the ice melts.
Which of course would not happen during our lifetime the sea’s estimated to rise about 216 feet.
Which would inundate all the shipping ports of the world.
As this would not happen in our lifetime the most pertinent question we could ask ourselves is, “why do we bother?’
Yes! It is fine but what would happen to the many generations to follow?
New Delhi as the capital of India is topping the list. As the most polluted city in the world are having Polluted Matter (PM). Far above the permissible limits declared by the World Health Organization (WHO).
Imagine the impact on human health. If this could happen in the Indian capital there is no reason why it cannot happen in the city we live too.
The disaster that took place at the Fukushima Nuclear power plant on the 11th of March 2011. Spewed radioactive rain particles in most other neighboring cities and countries as well.
Hence pollution of the environment would not effect only that particular city. And the skies above it but affect all others too.
The Benefits of Alternative Energy
The world is facing a crisis of environmental degradation. Alternative energy sources offer an effective solution.
The use of traditional fossil fuels like coal, oil, and gas. Has resulted in extensive damage to the environment. Including air pollution, soil erosion, water contamination, and climate change.

And the few solar farms in development around the world. They need extensive real estate space to house them.
But the learned scientists of the world have to find a way out of this predicament and bring out the solutions.
After all “necessity is the Mother of Invention” and the world is at a very crucial crossroads.
We need to protect our environment. And arrest the global warming and climate change phenomena. Plus, make our planet a safer place for our generations to follow.
The most convenient method available for us to tackle this change. Start using renewable and green energy sources.
It can definitely take us forward and make this world a healthy place for everyone to live for a long period of time.
We owe it to them and we have to make a concerted effort now. If we are to turn away from our dependence on fossil fuels. And bring clean and green energy into our lives and those of our children. You also know why we need renewable energy.
