Fossil fuels energy released

The curve projects a maximum yearly fossil fuel production capability of about 700 Q, which could be reached by 2050. It also projects the total exhaustion of the fossil energy supply by the year 2200. Besides being exhaustible, the burning of fossil fuels also releases carbon dioxide (COz) into the atmosphere. In spite of these facts, the global dependence on fossil fuels is projected to increase (Figure 1.2). 

One of the main benefits from future use of biofuels would be the reduction of greenhouse gases compared to the use of fossil fuels. Carbon dioxide, a greenhouse gas that contributes to global warming, is released into the air from combustion. Twenty-four percent of worldwide energy-related carbon emissions in 1997 were from the United States. Carbon... 

The energy from nuclear fission is released mainly as kinetic energy of the new, smaller nuclei and neutrons that are produced. This kinetic energy is essentially heat, which is used to boil water to generate steam that turns turbines to drive electrical generators. In a nuclear power plant, the electrical generation area is essentially the same as in a plant that burns fossil fuels to boil the water. 

A typical chemical reaction such as that in burning a fossil fuel releases about 10 eV of energy. A release... 

The fuels of modem society—natural gas, petroleum products, and coal—are called fossil fuels because they are formed from the decomposition of green plants over many millions of years. Like glucose, fossil fuels release energy when they react with oxygen to form carbon dioxide and water. 

Fossil fuels are nonrenewable, and combustion products contaminate the atmosphere. Consequently, scientists are searching for new sources of energy. One possibility is molecular hydrogen, which releases energy when it reacts with oxygen 2 H2(g) + 02(g) 2H2 0(/) + Energy Hydrogen powers the rockets of the space shuttle,... 

In order to reduce the problem of global warming, society needs to find alternative sources of energy. The problem with burning fossil fuels is that they release too much —... 

As energy-efficient technologies help to release us from fossil fuels, consumers will have a wider and more diverse set of energy sources, the economy will be more robust and the world more stable.
