The Plymouth Brethren are a conservative, low church, evangelical movement, whose history can be traced to Dublin, Ireland, in the late 1820s, originating from Anglicanism. Among other beliefs, the group emphasizes sola scriptura. Brethren generally see themselves not as a denomination, but as a network, or even as a collection of overlapping networks, of like-minded independent churches. Although the group refused for many years to take any denominational name to itself—a stance that some of them still maintain—the title The Brethren, is one that many of their number are comfortable with in that the Bible designates all believers as brethren.
When did the Plymouth Brethren originate?

A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions. Sometimes the status of great powers is formally recognized in conferences such as the Congress of Vienna or an international structure such as the United Nations Security Council (China, France, Russia, the United Kingdom and the United States serve as the body's five permanent members). At the same time the status of great powers can be informally recognized in a forum such as the G7 which consists of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States of America.

In 2004, a large share of natural gas reserves in Iran were untapped. The addition of new hydroelectric stations and the streamlining of conventional coal and oil-fired stations increased installed capacity to 33,000 megawatts. Of that amount, about 75% was based on natural gas, 18% on oil, and 7% on hydroelectric power. In 2004, Iran opened its first wind-powered and geothermal plants, and the first solar thermal plant is to come online in 2009. Iran is the third country in the world to have developed GTL technology.
How much did Iran's installed capacity of power increase to after it added new hydroelectric power in 2004?
33,000 megawatts
