The renewable energy sources are frequently considered alternative source since, many industrialized countries don't rely on them by their important source of energy. Rather, it tends to rely on sources of non-renewable such as nuclear power or fossil fuels. As the energy crisis in the America during the seventies, decreasing supplies fossil fuel and its hazard associated with nuclear energy, utilization of renewable energy sources has increased such as geothermal, hydroelectric, wind and biomass.
The solar energy is the simple energy source driving the environment. Although only 1 billionth of the energy that leaves the sunlight actually reaches the
surface of the earth and this is more than adequate to meet the requirement of world's energy. As a matter of fact, each other sources of energy, the
non-renewable and renewable are in reality stored forms of solar power.
The hydroelectric power is generated by using the energy of flowing water to power generating turbines for producing electrical energy. Nearly the
hydroelectric power is generated by dams across rivers large-flow. The dam built across river makes a reservoir behind that and the height of the H2O
behind the dam is larger than that the dam below, representing stored potential energy.
The wind is the effect of the sun's unequal atmosphere heating. The warm air rises and expands and cools air shrinks and contracts. This motion of the air
is called wind power. The wind has been used for millennia as a source of energy.
