lets look at the options we have

solar - have you read on how solar panel manufacturers pollute the environment? this is the lousiest excuse for green technology that you can ever get.

wind/wave - we have very low potential for this energy type. i believe tnb has done research on this locally.

nuke - this is considered RE? nvm. the biggest problem with this energy source is the power plant. how sure are you that the project won't be ali baba sub sub sub con to somebody else. even if we manage to build it, i doubt that we are gonna let it go operational. Philippines has already built one under the mega corrupt estrada's regime (finished, can be connected to the grid) . it still haven't gone online yet. go figure.

hydro - submerges large areas underwater. the place where you build this power plant will be very far from where the power is needed. (think bakun) so get ready to build that hvdc link. the converter stations and cables ain't cheap.

biomass - low power output i guess. try gastification on the biofuel and it might burn like coal.

don't see the production in china decreasing anytime soon. they already produce 28% (not latest figure) of world's solar panels ... plus, there's no guarantee other third world country producing solar panels don't have the same problem (think india)

-------------------------------------------------------------------------------------------------------------------------------------------

i have questions about solar panels.

solar panels consumes alot of energy to be produced. can someone specify how much? how long does a solar panel have to operate to offset the energy used to produce it?

edit: not arguing about this ... just wanna know since i have read about this somewhere.

Yes, it does manage to offset the energy used to produce the panels in the first place:

Given enough R&D, solar energy will be able to reach its maximum potential, efficiency, and feasibility.

so should we use it now when it have not reach its maximum potential?

-------------------------------------------------------------------------------------------------------------------------------------------

as for biomass, i have mentioned gastification before ...

an example would be this - a car powered by wood chips. using the same method, we can extract the carbon from our palm oil waste and use it to produce energy. this technology is currently being used for some coal power plants

try reading up on gastification. quite an interesting topic.

rexis: He had given the impression that all solar panel manufacturing is polluting. That is false, and I could give you many other examples of other forms of energy used in China which would be much cleaner if not for unscrupulous businessmen going for cash instead of thinking of the enviroment. It isn't inherent in solar panel manufacturing; all the pollutants can be processed; it is just that they refuse to.
*
businessmen wants to close their plants and move to china ... that tells you how much they care about the environment ... it doesn't matter what kind of method you have to reduce pollution (in this case, for the production of solar panels), if businessmen can't be bothered, the technology is as good as useless ... so unless there is a fuss free way to process the pollutants cheaply, we might as well say that the pollutants can't be processed

i would say biomass and hydro is our best bet ... they have a certain advantage over solar and that is their output is more manageable compared to solar and the technology is known to us

as for solar ... it should stay in the kiv tray for the time being ... for research, but not for use in the country yet

why should we argue about using solar when biomass does the job fairly well ... the power output from biomass is more consistent and it is superior in price ... plus, we are not gonna run out of rubbish and plantation waste to burn any time soon

in science, yes we talk about potential ... and solar has so a lot of potential ... in the real world tho, money speaks much much louder
