Global energy consumption in the last half century has increased very rapidly and is expected to continue to grow over the next 50 years. However, we expect to see significant differences between the last 50 years and the next. The past increase was stimulated by relatively “cheap” fossil fuels and increased rates of industrialization in North America, Europe, and Japan; yet while energy consumption in these countries continues to increase, additional factors are making the picture for the next 50 years more complex. These additional complicating factors include the very rapid increase fuel economy in energy use in China and India (countries representing about a third of the world’s population); the expected depletion of oil resources in the not-too-distant future; and the effect of human activities on global climate change.

Earth’s climate is a complex system of interacting natural components. These components include the atmosphere, the ocean, and the continental ice sheets. Living things on earth—or, the biosphere—also constitute an important component of the climate trends system.
Numerous factors influence Earth’s climate system, some of them natural. For example, the slow drift of continents that takes place over millions of years, a process known as plate tectonics, influences the composition of the atmosphere through its impact on volcanic activity and surface erosion.

Climatologists generally agree that there is accumulating evidence that a warming trend has been occurring since the mid-1960s. There are rather distinct seasonal and regional climate variations in the lower 48 states of the United States. Livezey and Smith determined that the average national warming trend has been 0.0151F per year. Since 1964, this implies that average annual temperature has increased by approximately one-half of one degree. (more…)

Biomass has been a main energy sources in the world since the beginning of civilization. It has been important in development processes, including early stages of industrialization in several countries. In Sweden, for example, the first concerns about preservation date from the seventeenth and eighteenth centuries, resulting from the recognition of the central role played by forests in energy provision. Biomass was also essential in the initial development of the iron industry in Sweden and, later on, the same happened in Brazil, where charcoal is still largely utilized in iron reduction. Biomass remains a major source of energy in many countries. (more…)

In the beginning, human progress was limited by the amount of work in single day. This is only to feed themselves and their families. At that time, the economy was largely rural as a result. In the early of 19th century, more intelligent human began to looking for energy resources to support their lives. They began to develop coal, oil, and other stored energy to supplement their prime energy source: sunlight. Sunlight energy results in overgrown plant and animal growth over huge and dispersed areas and geologic time periods. There was, and will continue to be, abundant solar energy sources available to get more fossil fuel, to do research on how to exploit these resources more efficiently, and to use them in daily life and changing their cultures.
