Defossilization
Defossilization: _ The goal of defossilization is to shift material sourcing away from fossil resources (red) to non-fossil resources, including carbon dioxide, biomass, or recyclate (green path) as seen in figure above. _ Section-1 Prologue: The 2026 Iran war—triggered by US-Israeli military strikes and Iran’s retaliatory actions—has sent profound ripple effects across the globe. The conflict has disrupted one of the world’s most vital maritime chokepoints and reshaped international trade. By disrupting and blocking the Strait of Hormuz, the conflict cut off roughly 20% of global oil & liquefied natural gas (LNG) supplies, and 30% of global fertilizer trade. Crude oil prices surged to nearly $100 a barrel, heavily elevating fuel costs for industries and consumers. Fossil fuels—predominantly coal, oil (petroleum), and natural gas—are primarily used to generate electricity, fuel transportation & cooking, provide industrial heating, and manufacture raw materials for plastics and fertilizers. They form the backbone of […]
COMBAT CLIMATE CHANGE
Combat Climate Change (CCC): ______ A Houston interstate after Hurricane Harvey in August 2017 _______ Prologue: Recently more than 15,000 scientists from 184 countries issued ‘warning to humanity’. The scientists around the world are very concerned about the state of the world, the environmental situation and climate change. Experts say worldwide average temperatures have already risen 1 degree Celsius since pre-industrial times, largely due to carbon emissions from the United States and Europe over the past century. Many countries are already feeling the heat that is enveloping the globe, with dramatic floods, hurricanes and droughts across the world in recent months adding a sense of urgency to the climate talks. On June 1, President Donald Trump announced that the United States will pull out of the Paris Agreement, a 2015 deal to curb carbon emissions, invest in green technology, and take other steps to combat the existential threat of climate […]
ELECTRICITY
ELECTRICITY: _ The picture above shows how a barber cuts hair during recent power failure in India. _ Prologue: Electric crematoria were snuffed out with bodies inside, New Delhi’s Metro shut down and hundreds of coal miners were trapped underground after three Indian electric grids collapsed in a cascade on 30th and 31st July 2012, cutting power to 620 million people in India. The blackout engulfed as many as 19 of India’s 28 states on July 31, with more than 100 intercity trains stranded and traffic lights went out in busy roads, causing widespread jams. Without question, it was the largest blackout in world history. Hospitals, factories and the airports switched automatically to their diesel generators during the hours-long cut across half of India. Many homes relied on backup systems of invertors with batteries. On the other hand, millions of India’s poorest had no electricity to lose. Of the […]
