This article provides a few interesting facts related to sources of renewable energy like water, geothermal and bio-energy. The potential of renewable energy is phenomenal.
Water (as a source of energy)
There is a vast depository of water on the earth surface. Did you know?
1. Water is the most known sources of renewable energy, and it is already providing energy requirements to some 28.3 million individuals.
2. Water has been acting as a source of power for more than 2000 years (various forms of energy).
1. The old Romans were among the first people to develop modern drainage systems, roads and to use geothermal energy to heat households.
2. Geothermal energy supply roughly 18 percent of the total energy needs in Philippines.
3. Some areas of the earth surface are closer to the core of the planet than others. In countries like Iceland, steam can be used to generate electricity directly from underground water.
1. Biomass (wood) provided up to 90 percent of total world’s energy requirements some 125 years ago.
2. Bio-fuel is becoming more commonly used as vehicle fuel; it does roughly represent 2 percent of total fuel consumption, and is growing fast.
3. Waste oil, such as oil that has been used by restaurant for deep fry can be converted into bio-diesel.
4. Types of Biomass
Woody Biomass: Forest’s products as well as short rotation coppice
Non-Woody Biomass: Industrial and biodegradable products, Animal waste, food processing, energy crops like Maize, sugar cane and rape.
5. Bio-diesel relinquishes a by-product known as glycerine: Glycerine has more than 1,500 different applications ranging from pharmaceuticals, cosmetics and food.
6. In North America, ethanol has been widely used as motor fuel since the early years of 1900s while during the Second World War several states were already using blended ethanol gas.
