Going Green is Driving a World Copper Shortage
A personal story kicked this one off This week I renewed the gas piping on my boat and wondered what to do with the old copper pipework. Copper is in big demand, for sure, but I’m not sure that 3 metres of scrap copper is worth much. 1/2 kg in weight? At $3.31 a US pound my copper is worth about $3. Maybe.

What is earthquake explain?
What is earthquake explain? An earthquake is a natural disaster that occurs when the ground shakes, usually caused by the movement of tectonic plates in the earth's crust. The movement of the plates can be sudden and violent, releasing a huge amount of energy that can cause the ground to shake, sometimes with great force. Earthquakes can cause buildings and other structures to collapse, and they can also trigger landslides, avalanches, and other types of natural disasters. The severity of an earthquake is typically measured using the Richter scale, which assigns a number to the magnitude of the earthquake based on the amount of energy released.

Human's make things
Introduction Global warming refers to the long-term warming of the planet due to the increase in greenhouse gases in the Earth's atmosphere. These greenhouse gases, such as carbon dioxide and methane, trap heat from the sun and cause the Earth's average temperature to rise. The main cause of global warming is the burning of fossil fuels, such as coal, oil, and natural gas, which releases large amounts of carbon dioxide into the atmosphere. Other human activities, such as deforestation and the use of certain industrial processes, also contribute to the increase in greenhouse gases.

Refrigeration Sucks 20% of the World's Energy Supply
Huge consumption This is what that august body, the International Institute of Refrigeration said in a 2019 report: The IIR estimates that the total number of refrigeration, air-conditioning and heat pump systems in operation worldwide is roughly 5 billion. Global annual sales of such equipment amount to roughly 500 billion USD. Over 15 million people are employed worldwide in the refrigeration sector which consumes about 20% of the overall electricity used worldwide.
