In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as the EU-15 plus Switzerland, Norway, and Iceland).

Water power sources is an interesting source of energy. It is available freely in nature. The constant flow of water can guarantee the availability of energy. Water power take it sources of energy from the motion of water. The motion of water is happening in river, sea and water fall. This movement can be derived from two resources:
1. Flows of water streams, this is attracted by earth gravity force
2. Tides which are the rise and fall of sea level by moon and sun gravity force (more…)

Brazil produced about 18.5 million metric tones (20.4 tons) of processed sugar in the 2001/2002 harvest, with approximately 9.45 million metric tones (10.4 tons) used domestically and the rest exported. Brazilian sugar is mostly derived from sugarcane, a drought-tolerant tropical and subtropical crop containing about 12 to 17% sugars (90% sucrose, 10% glucose) and 68 to 72% moisture. Brazil grew about 272 million metric tones (300 million tons) of sugarcane in the 2001/2002 season, making it second to India in world cane production that year. In 1975, Brazil adopted a Pro-Alcool Program to convert sugar to ethanol to reduce dependence on petroleum imports that were damaging the economy. (more…)

It is often useful to know how much energy is being changed from one form to another. For example, natural gas companies need to have a way to measure the fuel demands of their customers so they can provide enough natural gas advantages when it is most needed. (more…)
