The Science Behind Hydro-power - A Renewable Energy Source - and How It Helps an Island Cope With Power Shortage

Water is one form of renewable energy source and the power it produces is what we call as hydropower and from there it produces electricity which we are using in our homes, offices and factories.

Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower.

The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesn't necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine.

Another type of hydroelectric power plant - called a pumped storage plant - can even store power. The power is sent from a power grid into the electric generators. The generators then spin the turbines backward, which causes the turbines to pump water from a river or lower reservoir to an upper reservoir, where the power is stored. To use the power, the water is released from the upper reservoir back down into the river or lower reservoir. This spins the turbines forward, activating the generators to produce electricity.

Renewable energy business are steadily growing here in the Philippines as can be seen on the renewable energy investments coming from local private investors.

This form of renewable energy sources helps Sibuyan Island stabilized there supply of electricity which is scarcely supplied before by diesel generators.

Recent installation of the 900-kW hydroelectric turbines helps the locals improved their living by starting small businesses like hardware, food stalls groceries and  resorts catering to tourists. Not unlike when there is no stable supply of electricity when most people would only do farming and fishing.

As renewable energy business increase and more renewable energy investors continue funding projects like this, we can be sure that we are always moving on the right direction by creating jobs and addressing poverty issues.
