Essay Writing Contest:The Search for Energy Youth Leaders

Web Admin Advisory

This is to apprise all essay writing participants that we have scheduled the Awarding Rites on October 14, 2010, with tentative venue at New World Renaissance Hotel in Makati City.

 

We will notify the winners soon.

 

Since the nomination for our selected winner to an overseas conference will  not go along anymore with the deadline for the World Energy Council (WEC) conference in Canada, we are taking the option of sending him/her to the Climate Change Conference in Mexico this December or a nomination to the WEC Program for Youth, which is also overseas. We will correspondingly make announcement on that too during the awarding rites.

 

                                                   --- Essay Writing Secretariat

 

 

 

 

 

Believing in the immense potential of the next generation in helping shape the country’s energy future, the institutional and corporate partners of the Essay Writing Contest for College/University Students have introduced two Special Categories that aims to dig deeper into the ideas of the youth on how the country would be able to move forward from the vicious cycle of energy crisis and how this vital sector can contribute in the preservation of the environment and into abating climate change risks.

 

The two Special Categories revolve on the sub-themes: “Strategic Measures in Ensuring Success of a Competitive Electricity Market”, advocated by institutional partner Energy Regulatory Commission (ERC); and “Clean Energy Solutions”, which is supported by the Aboitiz Power Corporation. They were launched last June 11, 2010 at the Bryant George Hall of the Eduardo Aboitiz Development Studies Center in Cebu City.

 

In view of the latest developments, the organizers have decided to move deadline of submissions to July 31, 2010 (details are provided in the Contest Rules). The awarding rites will be scheduled August this year.

VECO raises the bar of customer service for electric utilities

 

 

The massive restructuring in the Philippine electric power sector presents downright challenges with new dimensions. Chiefly for the distribution utilities (DUs) which are the industry’s so-called frontliners, the battle chant is “improvement in customer service”.

 

Of course, no one is under illusion that to be imbued with responsibility of having direct contact with customers, especially in an industry so economically- and politically-charged would be a joyride. When there are sentiments frayed, in no doubt, there may be more drawbacks than one can imagine.

Renewable Energy: Understanding the Basics*

Simply put, Renewable energy is energy derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Present renewable energy sources supply about 18% of current energy use (see figure 1 & 2) and there is much potential that could be exploited in the future.

As the simple drawing will show, the technical potential of renewable energy sources is way beyond the current and even future global primary energy requirement.

 

Hydropower
 

Using renewable sources of energy has significant benefits to people. Renewable sources of energy are derived from natural processes that are replenish constantly. Compared to other sources of energy which uses oil, coal and nuclear technology to generate electricity renewable sources are a lot safer and environmental friendly.

Worldwide, hydro power plants produce about 24 percent of the world’s electricity and supply more than 1 billion people with power. The world’s hydro power plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of   oil, according to the National Renewable Energy Laboratory.

In the Phillipines, there are a handful of hydro power plants dispersedly located at the various countrysides of Luzon, Visayas and Mindanao. Almost all of the large hydroelectric power plants, which range from over 50 MW are connected to the main transmission grid, while most of small, (10 to 50 MW) and mini (101 to to 10 MW) are embedded to the local distribution system. The total installed generating capacity at the Phillipines is 15,937 MW. Hydro power plants accounts for about 3,289 MW (20.64%). On the other hand, the gross power generation is 59,612 GWh, hydro power acounts for about 8,563 GWh (14.36 %).

In this article, we’ll take a look at how falling water creates transforms energy into electricity known to us as hydropower. You will also get a glimpse at one unique application of hydropower that may affect your daily life.

When watching a river roll by, it’s hard to imagine the force it’s carrying. Hydropower plants harness water’s energy and use simple mechanics to convert that energy into electricity. Hydropower plantsare actually based on a rather simple concept, water flowing through a dam turns a turbine, which turns a generator.

 

Here are the basic components of a conventional hydropower plant
 
1. Dam - Most hydropower plants rely on a dam that holds back water, creating a large reservoir.
 
2. Intake - Gates on the dam open and gravity pulls the water through the penstock, a pipeline that leads to the turbine. Water builds up pressure as it flows through this pipe.
 
3. Turbine - The water strikes and turns the large blades of a turbine, which is attached to a generator above it by way of a shaft.
 
4. Generators - As the turbine blades turn, so do a series of magnets inside the generator. Giant magnets rotate past copper coils, producing alternating current (AC) by moving electrons.
 
5. Transformer - The transformer inside the powerhouse takes the AC and converts it to higher-voltage current
 
6. Power lines - Out of every power plant come four wires: the three phases of power being produced simultaneously plus a neutral or ground common to all three.
 
7. Outflow - Used water is carried through pipelines and re-enters the river downstream.
 
The water in the reservoir is considered stored energy. When the gates open, the water flowing through the penstock becomes kinetic energy because it’s in motion. The amount of electricity that is generated is determined by several factors. Two of those factors are the volume of water flow and the amount of hydraulic head. The head refers to the distance between the water surface and the turbines. As the head and flow increase, so does the electricity generated. The head is usually dependent upon the amount of water in the reservoir.

I still prefer nuclear power as total solution to enrgy problem. We need revive and reactivate the Bataan Nuclear Power Plant (BNPP) project in a move to increase electrical power generation more sufficiently and thereby bring down significantly the cost of electricity. We should have utilized BNPP long time ago as part of economic recovery solution. People’s money had been invested into this Bataan Nuclear Power Plant project that came into big waste. Did we stop it because of Chernobyl? Well, we cannot remain meticulous and choosy when in fact we are living poor, do we realize that some Filipinos are already eating from trashes. We are already living in danger, in fact poverty is endangering the lives of many poor Filipinos. Why afraid of the ghost already in your front? You need to confront your fears and recognize that ghost cannot kill anyone unless you decide to jump out of the window. If that is your dead grandfather’s soul then he might have a valuable message for you, like saying “I buried a crate with 10 tons of gold 10 feet below the generator room”. You can no longer get that when you’re already damn dead after making adverse decision. So why are we afraid of nuclear reactors? The voyaging US aircraft carriers are nuclear powered, they are traveling frequently so they are more prone to danger including the nearby coastlines they traverse. On the brighter side, nuclear powered countries were able to develop massive and long distance traveling trains, big shipyards, large hangars, numerous industrial plants, high rise constructions, and other infrastructure projects. Power grid system here in the Philippines may not be able to handle such heavy electrical loads. Even the electric generation charges, relying on present energy supply sources here makes it more costly to consumers both residential and industrial. In fact, some international manufacturing companies relocated their plants to other Asian nations with low cost of electricity. One example, I remember the Proctor and Gamble (P&G) plant in Makati, it is no longer in the Philippines. Check your shampoo or soap with P&G label, you will read, Manufactured by P&G Thailand; Imported by P&G Malaysia; Distributed by P&G Phils. Basically who is gaining much, the factory owner or the retailer? We were in recession since long time ago, even before Iran, Iraq, China, Korea, Vietnam, Thailand then US, because of bad decisions of our past and present leaders.

More to the Point: Energy Crisis in Mindanao

Mindanaons are angry that the administration has not been able to anticipate the crisis which had been foreseen by several experts. Now a state of calamity in Mindanao has been declared but many fear that this would give the administration reason to exercise emergency measures that may not be sustainable. In fact, senatorial candidate Joey de Venecia blames the administration for its “unexcused failure to put in the required base load capacity.” It also puts the blame on El Niño instead of looking at other factors such as its inability to plan ahead of time. What could have been done, he said, is to have invited foreign and local suppliers for the needed emergency generating sets instead of resorting to negotiated contracts, a common practice in the past.

A policy paper prepared by former Energy Secretary Francisco L.Viray and Myrna Velasco on “Crafting Energy Policies” for the Unicef-Asian Institute of Journalism and Communication publication, “The Future of Filipino Children,” examines some realities and alternatives. They note that although we are urged to shift from fossil fuels (coal and oil) to cleaner energy sources such as biofuels, renewable and nuclear energy, the reality is that oil, coal and natural gas remain the most abundant energy.

Rotating brownouts during sweltering summer months. Electricity price spikes at the spot market. And yes, there’s a Department of Energy (DOE) that failed in planning. Familiar scenes? Well, that was the State of California in the past decade before it hurtled into its monumental power market deregulation failure.

 

Now, the same events are being relived in Philippine shores. But if it is any stroke of luck, the local power industry appears more resilient, and fortunately, still has the room to save its deregulated market from teetering to failure.

On the night of October 8 last year, 23-year-old Norma Sapao lost six members of her family to a massive landslide triggered by a week of continuous, heavy rains that swept through their mountainside village of Little Kibungan in La Trinidad, Benguet.

 

To Sapao, whose two-year-old son was plucked out alive after being buried in mud and piles of debris for seven hours, the tragedy could be a freak of nature—a tragic event that could hit the unlucky, the unsuspecting.

 

“It’s horrifying and sad,” says Sapao. “I lost my family, my home was reduced into a pile of debris, and we have nowhere to go until now.”

How can something which is primarily used to generate electricity entice travelers that they will go out of their way just to see it?

 

Or to be more specific: who would have thought that the windmills of Ilocos Norte, which now supplies 40 percent of the electricity needs of this northern Philippine province, will become a major must-see site?

 

The coastal town of Bangui is not that accessible, you need to have your own vehicle to go there. And yet, hundreds of tourists have come and gone, not just for some beach bumming, but also to take photos of uhmm…. a windmill?

What’s visible in the eyes might not be comprehensible in political-savvy minds.
 
Take the case of the ‘biologically dead’ Pasig River – there are dodgy claims as to what have been triggering its continuously degrading state. To some sectors, the ‘blame compass’ conveniently swings in just the direction indicting the oil depots being “unwanted corporate residents’ along Pandacan stretch’s riverbanks.
