Biogas- principle and process Principle of biogas production Biogas is generated when bacteria degrade biological material in the absence of Oxygen, in a process known as Anaerobic Digestion. Since biogas is a mixture of methane (also known as marsh gas or natural gas, CH4) and carbon dioxide it is a renewable fuel produced from waste … Read more
The Greenhouse Effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s Atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. It is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a … Read more
Elements of Climate and weather Climate is decided by a region’s climate system. A climate system has few major components: the Atmosphere, the layer, the cryosphere, and the land surface. The atmosphere is that the most variable a part of the climate system. The composition and movement of gases encompassing the planet will change … Read more
Methane as a Greenhouse Gas: Methane is a greenhouse gas that is more potent than carbon dioxide. Methane is released from a variety of sources, including natural gas production, landfills, and agriculture. Methane is a major contributor to climate change. There are a number of ways to reduce methane emissions, including reducing natural gas leaks, … Read more
The subtopics of greenhouse gases are: Carbon dioxide Methane Nitrous oxide Ozone Water vapor Fluorinated gases Carbon dioxide is the most important greenhouse gas because it is the most abundant. It is released into the atmosphere when fossil fuels are burned, such as coal, oil, and natural gas. Methane is the second most important greenhouse … Read more
The greenhouse effect is a natural process that warms the Earth’s surface. When sunlight hits the Earth’s atmosphere, some of the energy is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the Earth’s atmosphere and surface. The greenhouse effect is essential to life on Earth. … Read more
