Biodiesel Fuel The biggest problem the United States faces today when we talk about becoming energy independent is replacing the gas we use to power our vehicles. When we talk about replacing gasoline as the fuel we use to power our vehicles‚ biomass‚ hydrogen‚ and fuel cells are the three most talked about alternatives. Biomass‚ which is organic material made from plants and animals‚ contains stored energy from the sun. Biomass in the form of bio fuels can be used to make the same products

purification of the water we drink. We also depend on it to dispose of some of our wastes. The increasing population within the world has had an impact on the lithosphere and consequently as led to the deterioration of this essential component of the biophysical environment. Land degradation has become one of the primary issues of concern arising from the human interaction with the lithosphere. It encompasses soil degradation and the deterioration of natural landscapes and vegetation. It includes

Cycles and Human Impacts The carbon cycle‚ nitrogen cycle‚ and phosphorus cycle all play a big role in our environment. They are some of the key components that are recycled to create pathways know as the biogeochemical cycles. All the chemical elements that make up living cells must be recycled continuously in order for the living components of a major ecosystem to survive. The recycling of these elements is the only possible way to maintain a dynamic system. Human impacts of these cycles

world is currently undergoing changes unlike ever recorded before in human history. Record breaking temperatures are occurring more frequently‚ carbon dioxide (CO2) emissions are at their highest rates since the Jurassic period‚ and a rapidly increasing population‚ fully reliant on our planets natural resources‚ are beginning to push the earth to its limit. On a local level‚ these environmental changes are having a significant impact on California’s environment. If this trend continues‚ California could

After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution‚ cheap fossil fuels then became the main source of energy. However‚ faced with the notable increase demand for energy‚ fossil fuel‚ as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem‚ the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy. This

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

Fossils of the Paleozoic Era The Earth is thought to be approximately 4.6 billion years old. For years researchers have turned to fossil remains to learn more about the earth and the organisms that have resided here. The history of the earth has been divided in to a widely accepted tine scale in order to make the study of the earths history more organized and understandable. The geologic time scale is used by all kinds of scientist‚ including geologist‚ anthropologist‚ and paleontologist as

Explain why fossil fuel exploration could lead to high economic and environmental costs. (10) A fossil fuel is a natural fuel such as coal or gas‚ formed in the geological past from the remains of living organisms. There are many environmental and economic costs behind the exploration of fossil fuels‚ and as demand is ever increasing‚ these costs in turn are multiplying. There have been many environmental costs linked to the exploration of fossil fuels. Firstly looking at fracking‚ which has
