In most countries, geothermal resources are classified as natural resources belonging to the government. Since the 1980s, there has been a worldwide trend to corporatize and/or privatize government commercial activities. Whereas the geothermal resources in the United States have been commercially developed by the private sector since the 1960s at The Geysers, other countries, notably The Philippines, Indonesia, and New Zealand, did not started private commercial geothermal projects until the 1980s. These private power developers are known as independent power producers (IPPs). There is a perception that the private sector is more efficient than the public sector. The efficiency arises from the increased flexibility of the private sector and its accessibility to commercial funding. (more…)

In 2006, total world wind generating electricity capacity was around 72,000 MW, producing some 160 terawatt-hours (TWh) per year of electricity. As of the end of 2006, the top wind producers were Germany, with 20,622 MW; Spain, with 11,615 MW; and the United States, with 11,575 MW.
Even so, wind accounts for only about 1 percent of the world’s total energy use. (more…)

The main reason why there is an on and off attempt of oil prices is due to depletion of our conventional energy. Our fossil fuel reserved almost nearly to its end. Hence, the world market tends to balance the trend of supply and demand. If that happens to be impossible, many countries will suffer because of insufficient of energy. We are going to take a look the advantages and disadvantages of wind energy and find out how to resolve this energy shortage. (more…)

There is a limited supply of energy resources for the world to use. There may come a time when the world faces a serious decrease in available energy. The small amount of energy we have at that time will not be enough for the populations of the world. Now is the time to consider planning towards our individual usages of energy. We need depend on natural energy such as solar energy as the new way to live. This will take a tremendous pressure off the surface energies we use today.
Many individuals consider the use of solar energy to be too expensive. (more…)

Statistics on national production levels and indicators of environmental pressure have been collected during the past few decades (and reconstructed for the more distant past) to document the link between world economic growth and the environment. The theory of world economic growth and economic theories of world natural resources provide explanations and interpretations of the trends as well as methods to assess future developments. The basic approach in most statistical and theoretical analyses is the decomposition of aggregate production function of a nation into, on the one hand, the current state of technology and, on the other hand, the inputs into the national production process. The main inputs are labor (hours worked), capital (produced means of production that can be used over a certain time period), and world natural resources. (more…)
