Introduction

Energy is most often used in the context of energy resources, their development, consumption, depletion, and conservation. Since economic activities such as manufacturing and transportation can be energy intensive, energy efficiency, energy dependence, energy security and price are key concerns. Increased awareness of the effects of global warming has led to international debate and action for the reduction of greenhouse gases emissions.

In the context of natural science, energy can take several different forms: thermal, chemical, electrical, radiant, nuclear, etc. These are often grouped as being either kinetic energy or potential energy. Many of these forms can be readily transformed into another with the help of a device; from chemical energy to electrical energy using a battery, for example.

The concepts of energy and its transformations are useful in explaining natural processes. Meteorological phenomena like wind, rain, lightning and tornadoes all result from energy transformations brought about by solar energy on the planet. Life itself is critically dependent on biological energy transformations; organic chemical bonds are constantly broken and made to make the exchange and transformation of energy possible.

Selected article

Investors worldwide have paid much greater attention to the renewable energy industry in recent years. In many cases, this has translated into rapid renewable energy commercialization and considerable industry expansion. The wind power industry and photovoltaics (PV) industry provide good examples of this. Leading renewable energy companies include Acciona, Enercon, Gamesa, GE Energy, Q-Cells, Sharp Solar, SunOpta, and Vestas. Read more...

Selected biography

Sheikh Ahmed Zaki Yamani (born 1930) was Saudi Arabia's Minister of Oil (Petroleum) and Mineral Resources from 1962 until 1986, and a minister in OPEC for 25 years. He is best known for his role in the 1973 oil crisis, when OPEC quadrupled the price of crude oil.

Yamani gained a degree from Harvard Law School and a master's in Comparative Jurisprudence from New York University. After working in the Saudi Ministry of Finance, in 1958 be became a legal advisor to Faisal, then Crown Prince and Prime Minister, until Faisal's resignation in 1960. After Faisal's return to government, in 1962 Yamani replaced Abdallah Tariki as Oil Minister, playing an important role in the development of OPEC. During the 1967 Arab-Israeli War Yamani spoke against the use of an Arab oil embargo. The following year he lead the founding of the Organisation of Arab Petroleum Exporting Countries.

When Arab-Israeli hostilities resumed with the 1973 Yom Kippur War, the pressure to join the other Arab states, who wished to use oil to change the apparent pro-Israeli policy of the United States government, was irresistible. Yamani's proposal of increasing monthly cuts in production was accepted and, together with a later embargo against the US and the Netherlands and a quadrupling of the oil price, severely affected the economies of all western nations. Despite this, by resisting more extreme proposals Yamani became increasingly seen as pro-American in the Arab world. Read more...
