SOLAR Power is the way to go

[b_9904]

A. You can get it yourself and be independent and sell your excess to the market.

B. The government can lease your rooftop, and pay you through discounts and incentives in your electric bills.

That is if your government is going to do something about it, might as well just go noynoying, much better hey they are getting paid and with pork barrel so who cares.

Presently, solar panels are expensive and inefficient. Mayhap future panels may solve our problems.

We could also go by the way of ALCOHOL but we need to make production of alcohol more efficient so as not to drive the prices of food up AND for it to REALLY contribute to lowering greenhouse emissions.

[cyberfunk]

No, you can't sell the excess electricity back to the grid here. No, the government will not give you tax incentives.

Solar panel system large enough to supply your house to be efficiently off-the-grid here will take 30 years for your investment to return. Wherein, Solar system manufacturers will only gives 10 to 15 year warranties.

There was news long ago about how the government favor a certain type of alcohol producing process for something that would benefit a group of favored people.

Nuclear is the answer. BNP was such a waste
Pinoy should stop buying the fear on nukes that media sells. 6 or more years from now, our neighbors will be enjoying the benefits of it while we still scratch our head as to why we are still too dependent on imported oil.

A solar panel big enough to supply your house would not probably fit on your entire house and lot

Unless for some reason you hate refrigerators, the microwave, and computers.

Actually, if we want to "nip the rose by the bud" then we should come up energy efficient technologies and solutions.

Not that big naman. Wala pang 30sqm. Pero abutin mahigit 1M kung talagang mag off-the-grid ka.

Solar Power generation plants would require large track of land. this means the philippines has to allot areas for power generation rather than food production or cut down trees.
........

Maybe the Philippines will not be big enough to have space for equipmet for solar power that will supply energy to the whole country!

[blue_tracer]

mahina lang ang power na binibigay ng solar eh.

mainit sa pinas, heavy use sa fan at aircon ang mga tao. sa heavy industries rin halimbawa, papano 'yan patatakbuhin ng solar?

pang back-up lang talaga siya.

unlike desert countries that have vast waste lands na pwede lagyan ng solar plants

dito sa pinas, barely developed pa and God forbid that rain forests be cut down to erect these solar panels.

maganda na back up ang solar panels but here in mindanao dahil sa cloudiness most of the time medyo ineffective minsan ang output ng cepalco solar plant. it's only 1 megawatt if I'm not mistaken.


sa halip, natural sources such as the water falls which are actually abundant here should be prioritized. ang problem is walang additional investment made sa current hydro plants.

on the plus side, electricity generated by old hydro plants is actually cheap.

kaya naglalaway ang lopezes who already control the geothermal plant and raised the costs by 70% and created a shortage by withholding energy from the said plant.

the funny thing is Mindanao has a lot of electricity, so much cheap electricity from solar, geothermal and hydro plants and if you include the coal plants, the oligarchs want to funnel the electricity and connect the power grid of mindanao to visayas and luzon.

pero may "shortage" ang mindanao ngayon.

ironic

[b_9904]

^hydro plants have its own issues especially with the environmental opportunity cost.

re: cloudiness

well that is expected sa Pinas.

re: geothermal plants

its unpredictable because the vents spout out heat and steam at different levels in a given day, week, month, or year.

bottom line

all sources of power has its own pros and cons, even the "green" ones.

re: connection

dapat naman talag i connect na ang lahat ng isla ng Pilipinas eh.

kaya nga it's always best to have multiple sources of "green" energy which is mindanao is doing the right thing by having a solar, hydro and geothermal plant.

as for the connection of the power grid, ma dilute ang power supply ng green plants dito. they can't even solve the current problem here in mindanao and they want the plants here to share electricity to luzon?

mindanao is thriving kahit may corruption due to relatively low power rates and water bills

tama 'yan. nagbibigay pa rin naman ng power ang solar + wind + geothermal + etc. pero maliban nga sa mahina lang siya, realistically speaking, intermittent ang supply niya eh.

sa mga important establishments/structures like hospitals na nagme-maintain ng highly delicate medical instruments 24/7, hello i-aasa ba natin sa araw?

yung solar panels sa dagat.. puwede. naisip ko lang ang gastos sa maintenance niyan. salty ang environment, so maraming components ang dapat stainless steel ( grade 316), fasteners like grade A4. and these aren't cheap. kung steel framings ang gagamitin grabe ang protective coating nito.. etc. parang mahal ah.

kung ngayon pa lang napapaisip ang mga taga mindanao na mag nuclear, early 70s pa lang sumagi na sa isip ni marcos ang nuclear energy.

ilang bilyon na sanang revenue ang inani ng bansa dahil sa efficiency ng nuclear?

takot lahat sa nuclear. pero sa mala-tsunami na bills sa kuryente hindi?

at this time, mag quit man ang japan sa nuclear energy dahil sa hazard nito okay lang, na propelled na sila ng pagkalayo-layo na eh.

tayo, anong i-quit natin?

ang malaking irony pa niyan, sila nga itong nakaranas pa mismo ng lupit ng atomic bomb.

huwag na tayo umasa ng solution sa pnoy henyo at take it or leave it lang ang binigay na solution niya mindanao.

That's inadvisable.

The project will kill the ecosystem of the water body specially in oceans/ seas. The aquatic photoautotrophs and photosynthetic species which are the base of the food web will decrease, eventually die. Corals which provides shelter and nesting grounds will also affected since sunlight will be blocked by solar panels.

Food supply will also be affected by the chain reaction effects.

actually in dubai, there is a german company that proposed having a floating solar cell plant. they built a prototype on a gigantic inflatable pool. its still under study because they are looking on how it will fare with tides, waves and water spray.

its a good idea to locate it in a lake but not in a dam. dams are surrounded by a water shed which will cast shadow on the collectors. and the water level of dams are easily affected by the weather.

sa desert areas ayus 'yang solar panels.

bagyuhin sa pinas. vulnerable sa debris ang panels nito.

makakatulong ang solar energy. kaso pagbali-baliktarin man natin, kulang ang power. tulad sa mga factories malalakas kumain ng kuryente, i think solar energy alone wont be enough.

backup lang siya, 'di siya feasible maging main source of energy. i could be wrong. pero tantiyahin ninyo ilang megawatts maibibigay niyan per square kms.

The most feasible way and to maximize solar energy is place it in outer space. I know there are studies now regarding this technology, converting the solar energy collected by solar panels and transform it to microwave and beam it to a receiver in the earth's surface. 24/7 ang collection ng solar power dahil walang clouds and other things na tatakip o makakaapekto sa solar panels.

Napanood ko ng ginawa yan sa discovery channel at effective siya, they transmitted microwave energy from solar energy sa dalawang magkahiwalay na location, nakapag-charge sila ng mobile phone.

Pero masyado ng advance yan para sa Pinas, di nga tayo makagawa pa ng rocket at wala man lang space program.

Solar power from space
Beam it down, Scotty
Harvesting solar power in space, for use on Earth, comes a step closer to reality

Jun 23rd 2011 | from the print edition

THE idea of collecting solar energy in space and beaming it to Earth has been around for at least 70 years. In “Reason”, a short story by Isaac Asimov that was published in 1941, a space station transmits energy collected from the sun to various planets using microwave beams.

The advantage of intercepting sunlight in space, instead of letting it find its own way through the atmosphere, is that so much gets absorbed by the air. By converting it to the right frequency first (one of the so-called windows in the atmosphere, in which little energy is absorbed) a space-based collector could, enthusiasts claim, yield on average five times as much power as one located on the ground.

The disadvantage is cost. Launching and maintaining suitable satellites would be ludicrously expensive. But perhaps not, if the satellites were small and the customers specialised. Military expeditions, rescuers in disaster zones, remote desalination plants and scientific-research bases might be willing to pay for such power from the sky. And a research group based at the University of Surrey, in England, hopes that in a few years it will be possible to offer it to them.
In this section

Heavenly power

This summer, Stephen Sweeney and his colleagues will test a laser that would do the job which Asimov assigned to microwaves. Certainly, microwaves would work: a test carried out in 2008 transmitted useful amounts of microwave energy between two Hawaiian islands 148km (92 miles) apart, so penetrating the 100km of the atmosphere would be a doddle. But microwaves spread out as they propagate. A collector on Earth that was picking up power from a geostationary satellite orbiting at an altitude of 35,800km would need to be spread over hundreds of square metres. Using a laser means the collector need be only tens of square metres in area.

Dr Sweeney’s team, working in collaboration with Astrium, a satellite-and-space company that is part of EADS, a European aerospace group, will test the system in a large aircraft hangar in Germany. The beam itself will be produced by a device called a fibre laser. This generates the coherent light of a laser beam in the core of a long, thin optical fibre. That means the beam produced is of higher quality than other lasers, is extremely straight (even by the exacting standards of a normal laser beam) and can thus be focused onto a small area. Another bonus is that such lasers are becoming more efficient and ever more powerful.

In the case of Dr Sweeney’s fibre laser, the beam will have a wavelength of 1.5 microns, making it part of the infra-red spectrum. This wavelength corresponds to one of the best windows in the atmosphere. The beam will be aimed at a collector on the other side of the hangar, rather than several kilometres away. The idea is to test the effects on the atmospheric window of various pollutants, and also of water vapour, by releasing them into the building.

Assuming all goes well, the next step will be to test the system in space. That could happen about five years from now, perhaps using a laser on the International Space Station to transmit solar power collected by its panels to Earth. Such an experimental system would deliver but a kilowatt of power, as a test. In 10-15 years Astrium hopes it will be possible to deploy a complete, small-scale orbiting power station producing significantly more than that from its own solar cells.

Other researchers, in America and Japan, are also looking at using lasers rather than microwaves to transmit power through the atmosphere. NASA, America’s space agency, has started using them to beam energy to remotely controlled drones. Each stage of converting and transmitting power results in a loss of efficiency, but with technological improvements these losses are being reduced. Some of the latest solar cells, for instance, can covert sunlight into electricity with an efficiency of more than 40%. In the 1980s, 20% was thought good.

Whether the Astrium system will remain a specialised novelty or will be the forerunner of something more like the cosmic power stations of Asimov’s imagination is anybody’s guess. But if it comes to pass at all, it will be an intriguing example, like the geostationary communications satellites dreamed up by Asimov’s contemporary, Arthur C. Clarke, of the musings of a science-fiction author becoming science fact.

By connecting Mindanao to the rest of the country any deficiency in the island can be offset by the excess in another and vice versa.

well mas magandang i-asa sa fossil fueled or nuclear power plants ang mga equipment ng hospitals. Pero pwede i-asa sa "green" sources ang mga ilaw sa hallway, office, rooms, electric fans, etc.

yung solar panels sa dagat.. puwede. naisip ko lang ang gastos sa maintenance niyan. salty ang environment, so maraming components ang dapat stainless steel ( grade 316), fasteners like grade A4. and these aren't cheap. kung steel framings ang gagamitin grabe ang protective coating nito.. etc. parang mahal ah.

Mahal naman talaga pero may technology na silang ginagamit dyan para maging corrosion resistant yung structure. Dunno the details though.

kung ngayon pa lang napapaisip ang mga taga mindanao na mag nuclear, early 70s pa lang sumagi na sa isip ni marcos ang nuclear energy.

well, madaming issues ang "nuclear" sa bansang ito. kahit nga sa constitution natin bawal magkaroon ng nuke ang Pilipinas.

IMHO, there is no problem with nuclear energy, its just that takot lahat sa Pinas kasi baka substandard ang gagawin at magka-meltdown. Pwede ding misinformation or propaganda campaign ng mga anti-nuclear advocates.

at this time, mag quit man ang japan sa nuclear energy dahil sa hazard nito okay lang, na propelled na sila ng pagkalayo-layo na eh.

The reason Japan entered WWII was because the US cut Japan's oil lifeline. Kaya I dont think Japan will abandon nuclear energy unless may mas reliable at safer na energy source silang madiskubre.

That's inadvisable.

Your point will count if you cover and concentrate the structure within a single HUGE area of the sea. If you scatter them and place them far from reefs the structures will not harm our ecosystem.

its a good idea to locate it in a lake but not in a dam. dams are surrounded by a water shed which will cast shadow on the collectors. and the water level of dams are easily affected by the weather.

I dont get it. So what kung waterhsed sila, so what kung affected sila ng weather, will the panels poison the dam or affect rainfall?

Well hindi talaga ito feasible para sa Pilipinas

How about the Philippines harvest TIDAL energy as a short term "green" energy source?
